All of them come from real measurements, and none of them is simply wrong. That is the most useful thing to understand about this sweetener. The short answer: crystalline maltitol measures around 36 on the glycemic index, maltitol syrup measures around 52, and sucrose sits near 65 (Saraiva et al., 2020). So yes, maltitol raises blood sugar, but less than sugar does. Everything else worth knowing (why real products refuse to obey the chart, what keto and diabetes communities actually disagree about, and what all of this means for labels and sourcing) hangs off those three numbers. This guide takes them in order.<\/p>\n<h2>What the Number Actually Says, and Why It Comes in Two Versions<\/h2>\n<p>Maltitol is a sugar alcohol (polyol) made by hydrogenating maltose syrup derived from corn or tapioca starch. It delivers roughly 75\u201390% of sucrose’s sweetness at about 2.1 kcal per gram, does not promote tooth decay, and is approved in major markets including the EU (as E 965) (Saraiva et al., 2020). One disambiguation before anything else: maltitol is not maltodextrin. Maltodextrin is a starch-derived glucose polymer that scores near the very top of the glycemic scale, close to pure glucose (GI 100 by definition of the scale). The two names collide constantly in comment sections, and they behave nothing alike. Everything below is about maltitol, the polyol.<\/p>\n\n<div class=\"bp-1-hook bd-reveal\">\n <p class=\"bp-1-hook-quote\"><span class=\"bp-1-hook-icon\"><svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"22\" height=\"22\" viewBox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"><path d=\"M16 3a2 2 0 0 0-2 2v6a2 2 0 0 0 2 2 1 1 0 0 1 1 1v1a2 2 0 0 1-2 2 1 1 0 0 0-1 1v2a1 1 0 0 0 1 1 6 6 0 0 0 6-6V5a2 2 0 0 0-2-2z\"\/><path d=\"M5 3a2 2 0 0 0-2 2v6a2 2 0 0 0 2 2 1 1 0 0 1 1 1v1a2 2 0 0 1-2 2 1 1 0 0 0-1 1v2a1 1 0 0 0 1 1 6 6 0 0 0 6-6V5a2 2 0 0 0-2-2z\"\/><\/svg><\/span><span class=\"bp-1-hook-key\">36 vs 52<\/span>: one ingredient name, two glycemic answers, 16 points apart. The form of maltitol on the label decides which answer applies.<\/p>\n<\/div>\n<p>Why two answers for one name? Crystalline maltitol is a high-purity single molecule (specification-grade powder assays at 98%+ maltitol), and it measures GI \u224836. Maltitol syrup is not diluted crystalline maltitol. Commercial syrup grades carry roughly half or more of their solids as maltitol, together with a significant fraction of hydrogenated oligosaccharides (larger hydrogenated saccharides) and a controlled sorbitol fraction (\u22648.0% in the common 75% grade). Those hydrogenated oligosaccharides are what push the syrup’s GI up to 52 (Saraiva et al., 2020). The popular claim that maltitol has “about half the glycemic impact of sugar” is accurate for the crystalline form (36 vs ~65) and optimistic for syrup, which lands closer to two-thirds of sugar’s impact.<\/p>\n<p>Context helps, so here is maltitol against the sweeteners it usually shares a label with. Treat these as published approximations: exact values vary by study, method, and form.<\/p>\n\n<div class=\"rich-table bd-reveal\">\n <p class=\"rich-table-title\">Common Sweeteners by Glycemic Index (published approximations)<\/p>\n <div class=\"table-wrapper\">\n <table>\n <thead><tr><th>Sweetener<\/th><th>GI (approx.)<\/th><th>Note<\/th><\/tr><\/thead>\n <tbody>\n <tr><td data-label=\"Sweetener\">Erythritol<\/td><td data-label=\"GI (approx.)\">~0<\/td><td data-label=\"Note\">Excreted unchanged; best-in-class glycemic profile<\/td><\/tr>\n <tr><td data-label=\"Sweetener\">Lactitol<\/td><td data-label=\"GI (approx.)\">~6<\/td><td data-label=\"Note\">Polyol<\/td><\/tr>\n <tr><td data-label=\"Sweetener\">Isomalt<\/td><td data-label=\"GI (approx.)\">~9<\/td><td data-label=\"Note\">Polyol<\/td><\/tr>\n <tr><td data-label=\"Sweetener\">Sorbitol<\/td><td data-label=\"GI (approx.)\">~9<\/td><td data-label=\"Note\">Polyol<\/td><\/tr>\n <tr><td data-label=\"Sweetener\">Xylitol<\/td><td data-label=\"GI (approx.)\">~13<\/td><td data-label=\"Note\">Polyol<\/td><\/tr>\n <tr><td data-label=\"Sweetener\">Maltitol (crystalline)<\/td><td data-label=\"GI (approx.)\">~36<\/td><td data-label=\"Note\">Highest-GI common polyol<\/td><\/tr>\n <tr><td data-label=\"Sweetener\">Maltitol syrup<\/td><td data-label=\"GI (approx.)\">~52<\/td><td data-label=\"Note\">Hydrogenated oligosaccharides push it up<\/td><\/tr>\n <tr><td data-label=\"Sweetener\">Sucrose<\/td><td data-label=\"GI (approx.)\">~65<\/td><td data-label=\"Note\">Reference<\/td><\/tr>\n <\/tbody>\n <\/table>\n <\/div>\n <p class=\"rich-table-source\">DataSource: Saraiva et al. 2020; GoodRx 2024; KetoConnect<\/p>\n<\/div>\n<p>If you have seen figures from 29 to 52 attached to maltitol, you now know where they come from: different forms, different assay methods, different eras of testing. They all collapse into the form-qualified pair above. (Maltitol’s other famous issue, digestive distress, is a separate dose-dependent story with its own thresholds; it is covered in a <a href=\"https:\/\/www.saigaoingredients.com\/blogs\/safety-and-tolerability-of-maltitol-syrup\/\">separate guide to maltitol’s digestive tolerance<\/a>.)<\/p>\n<p>The number is now qualified. The next question is why your own glucose curve sometimes refuses to follow it.<\/p>\n<h2>Why Real Products Don’t Match the Chart<\/h2>\n<p>A GI value is measured under standardized conditions: 50 grams of available carbohydrate, fasting subjects, blood sampled at fixed intervals for two hours. Real life violates every one of those conditions at once, in four predictable ways.<\/p>\n<h3>The Dose and the Carrier<\/h3>\n<p>The 50-gram standard matters because dose and vehicle drive the response. In a controlled trial, a single 50 g dose of maltitol produced significantly lower glucose and insulin responses than the same dose of sucrose in healthy young subjects (Msomi et al., 2021). Change the dose or the matrix, though, and the picture shifts. Fat and protein in a chocolate or ice-cream base slow gastric emptying and flatten the curve; a gummy carrier does not. Continuous glucose monitor (CGM) users report the same brand of sugar-free chocolate spiking them hard in the caramel variety and barely registering in the mint variety from the same package line: the filling changed the response, not the sweetener listed on the front. Serving-size accounting does the rest of the damage. Community threads are full of people who treated a small container as one serving and doubled the intended polyol load, then spent months blaming their A1C trajectory on everything else.<\/p>\n<h3>Crystal vs. Syrup: the Material Difference<\/h3>\n<p>The form effect from the first section has a material basis, and it shows up in more than one metric. The glycemic spread (crystalline \u224836, syrup \u224852) tracks the hydrogenated oligosaccharide content of the syrup (Saraiva et al., 2020). The insulin index spreads the same way: pure maltitol measures around 27, while high-polymer maltitol syrups can reach the mid-40s (Paleo Foundation, 2020). That matters most for keto readers, because insulin is the hormone that suppresses ketone production. For formulators, form is the first glycemic lever available: same sweetener family, same sweetness ballpark, measurably different metabolic signature. For shoppers, the practical rule is that “maltitol” on an ingredient list can mean either material, and maltitol syrup is the one to expect more from.<\/p>\n\n <img decoding=\"async\" src=\"https:\/\/www.saigaoingredients.com\/wp-content\/uploads\/2026\/09\/Maltitol-Glycemic-Index.webp\" style=\"width: 512px; height: 384px; max-width: 100%; object-fit: cover; border-radius: 12px; margin: 30px auto; display: block; box-shadow: 10px 10px 60px 0px rgba(210, 221, 224, 0.35); transition: all 0.3s ease; cursor: pointer;\" onmouseover=\"this.style.transform='translateY(-5px) scale(1.03)'; this.style.boxShadow='15px 25px 80px 0px rgba(210, 221, 224, 0.45)'\" onmouseout=\"this.style.transform='translateY(0) scale(1)'; this.style.boxShadow='10px 10px 60px 0px rgba(210, 221, 224, 0.35)'\"> \n\n<h3>The Net-Carb Accounting Problem<\/h3>\n<p>Labels feed the confusion. In US practice, manufacturers subtract sugar alcohols from total carbohydrate when calculating “net carbs,” as if all polyols behaved like erythritol. Maltitol does not. A common clinical rule of thumb is to subtract only half the sugar-alcohol grams; the American Diabetes Association sidesteps the debate entirely and instructs people with diabetes to count total carbohydrate (American Diabetes Association, 2026; Medtronic). Run the arithmetic on a bar that advertises 2g net carbs from 18g of maltitol and you get something that behaves like roughly 9\u201315g of ordinary carbohydrate, depending on form and individual response. The label number is not a lie, but it is an accounting choice, not a metabolic measurement.<\/p>\n<p>Put the four variables together and each deviation from the chart becomes diagnosable.<\/p>\n\n<div class=\"rich-table bd-reveal\">\n <p class=\"rich-table-title\">Why Your Glucose Response Differs From the GI Chart<\/p>\n <div class=\"table-wrapper\">\n <table>\n <thead><tr><th>Serving scenario<\/th><th>Form basis<\/th><th>Expected response<\/th><th>What to do<\/th><\/tr><\/thead>\n <tbody>\n <tr><td data-label=\"Serving scenario\">Small portion (\u226410g maltitol), taken with a meal<\/td><td data-label=\"Form basis\">Either<\/td><td data-label=\"Expected response\">Mild, slow rise; often hard to distinguish from noise<\/td><td data-label=\"What to do\">Standard tolerance zone for most people<\/td><\/tr>\n <tr><td data-label=\"Serving scenario\">Typical serving (10\u201325g) of crystalline-based product<\/td><td data-label=\"Form basis\">Crystalline<\/td><td data-label=\"Expected response\">Modest rise on the GI \u224836 pattern<\/td><td data-label=\"What to do\">Reasonable; verify with CGM if diabetic or strict keto<\/td><\/tr>\n <tr><td data-label=\"Serving scenario\">Typical serving of syrup-based confectionery<\/td><td data-label=\"Form basis\">Syrup<\/td><td data-label=\"Expected response\">Earlier, higher rise on the GI \u224852 pattern<\/td><td data-label=\"What to do\">Check the ingredient list; expect more from this form<\/td><\/tr>\n <tr><td data-label=\"Serving scenario\">Whole-container or repeated servings (30g+ polyol)<\/td><td data-label=\"Form basis\">Either<\/td><td data-label=\"Expected response\">Response approaches sugar territory as dose stacks<\/td><td data-label=\"What to do\">Count it as real carbohydrate (digestive limits arrive separately)<\/td><\/tr>\n <\/tbody>\n <\/table>\n <\/div>\n <p class=\"rich-table-source\">DataSource: Conditions synthesized from Saraiva et al. 2020; Msomi et al. 2021; ADA guidance; CGM user reports<\/p>\n<\/div>\n<h2>Keto and Diabetes: Same Number, Different Verdicts<\/h2>\n<p>Ask the keto question and you get three defensible answers that contradict each other. Diet Doctor tells readers to avoid maltitol outright (Diet Doctor, 2026). KetoConnect put 50 grams of maltitol syrup to a fingerstick test and watched blood sugar climb about 40 points in 30 minutes, concluding it is “a major no-no” (KetoConnect). MedicineNet, at the other end, describes maltitol’s rise as small, slow, and gradual. Meanwhile the Paleo Foundation reviewed the top-ranking “maltitol keto” content in 2019, found roughly 80% of it negative, disagreed with the majority’s reasoning, and formally added maltitol to its Keto Certified standards (Paleo Foundation, 2020). The camps are not arguing about the data; they are optimizing different things. Keto optimizes ketone production, which insulin suppresses, so form and dose decide: 50g of syrup form will threaten ketosis, while a small crystalline-form portion in a mixed, low-carb day may not register at all. The working verdict: strict keto has better tools and rarely needs to take the risk; liberal low-carb eaters can self-test small portions and decide on their own data.<\/p>\n<p>Ask the diabetes question and the split repeats at higher stakes. Diabetes.co.uk calls maltitol “beneficial for people with diabetes” because it produces lower glucose and insulin rises than sugar (Diabetes.co.uk, 2023). ConsumerLab concludes it is “not a problematic ingredient” for type 2 diabetes (ConsumerLab). A widely upvoted r\/prediabetes post argues the opposite: treat maltitol-sweetened products as neither sugar-free nor low-glycemic. All three are defensible because they compare maltitol against different baselines. Against sugar, maltitol is genuinely lower (Msomi et al., 2021). Against zero-carb sweeteners like erythritol, stevia, or allulose, it is genuinely higher. Between those baselines sits enormous individual variance, which is why the ADA skips the category debate and tells people to count total carbohydrate and watch their own readings. Note what “diabetic-friendly” on a front panel does and does not mean: it is a marketing phrase, not a clinical license.<\/p>\n\n<div class=\"rich-table bd-reveal\">\n <p class=\"rich-table-title\">Two Frameworks, Two Working Verdicts<\/p>\n <div class=\"table-wrapper\">\n <table>\n <thead><tr><th>Framework<\/th><th>What it optimizes<\/th><th>Where maltitol lands<\/th><th>Working verdict<\/th><\/tr><\/thead>\n <tbody>\n <tr><td data-label=\"Framework\">Strict keto<\/td><td data-label=\"What it optimizes\">Ketone maintenance (insulin-sensitive)<\/td><td data-label=\"Where maltitol lands\">Worst common polyol on glycemia and insulin index; syrup form far worse<\/td><td data-label=\"Working verdict\">Prefer erythritol, allulose, stevia, monk fruit<\/td><\/tr>\n <tr><td data-label=\"Framework\">Liberal low-carb<\/td><td data-label=\"What it optimizes\">Carb minimization with flexibility<\/td><td data-label=\"Where maltitol lands\">Moderate impact, dose- and form-dependent<\/td><td data-label=\"Working verdict\">Self-test small crystalline-form portions; keep syrup-form out<\/td><\/tr>\n <tr><td data-label=\"Framework\">Type 2 diabetes<\/td><td data-label=\"What it optimizes\">Post-meal glucose control<\/td><td data-label=\"Where maltitol lands\">Lower than sugar, higher than zero-carb sweeteners<\/td><td data-label=\"Working verdict\">Count total carbs (ADA), watch your own response, treat “diabetic-friendly” as marketing<\/td><\/tr>\n <\/tbody>\n <\/table>\n <\/div>\n <p class=\"rich-table-source\">DataSource: Verdicts synthesized from sources cited in text<\/p>\n<\/div>\n<p>Both frameworks converge on the same exit, which is the only part of this argument that never goes stale: measure your own response.<\/p>\n\n<div class=\"rich-steps bd-reveal\">\n <p class=\"rich-steps-title\"><span class=\"rich-ticon\"><svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"20\" height=\"20\" viewBox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"><circle cx=\"6\" cy=\"19\" r=\"3\"\/><path d=\"M9 19h8.5a3.5 3.5 0 0 0 0-7h-11a3.5 3.5 0 0 1 0-7H15\"\/><circle cx=\"18\" cy=\"5\" r=\"3\"\/><\/svg><\/span>The self-test protocol<\/p>\n <div class=\"rich-steps-list\">\n <div class=\"rich-steps-item\"><span class=\"rich-steps-chip\">1<\/span><p class=\"rich-steps-text\">Pick one product and one fixed portion; do not change two variables at once.<\/p><\/div>\n <div class=\"rich-steps-item\"><span class=\"rich-steps-chip\">2<\/span><p class=\"rich-steps-text\">Test it fasting once and with a meal once; the difference is often larger than the sweetener effect.<\/p><\/div>\n <div class=\"rich-steps-item\"><span class=\"rich-steps-chip\">3<\/span><p class=\"rich-steps-text\">Repeat 2\u20133 times before concluding; single readings mislead.<\/p><\/div>\n <div class=\"rich-steps-item\"><span class=\"rich-steps-chip\">4<\/span><p class=\"rich-steps-text\">Keto readers add a ketone check 2\u20133 hours after; some users watch ketones dip for hours after syrup-form products.<\/p><\/div>\n <div class=\"rich-steps-item\"><span class=\"rich-steps-chip\">5<\/span><p class=\"rich-steps-text\">Log the form (crystal or syrup) next to the result; the same brand name can hide different materials.<\/p><\/div>\n <\/div>\n <p class=\"rich-steps-note\">Note: individual reports cover both extremes (six-week CGM users flat “like eating chicken,” self-testers up 40 points in 30 minutes).

Its specification language is mature: ask for assay 98.0\u2013100.5% (dry basis), reducing sugars \u22640.1%, and conductivity \u226420 \u00b5S\/cm, referenced to USP\/BP\/FCC. That is the grade behind the GI \u224836 data. Maltitol syrup exists for a reason (it inhibits crystallization in hard candy, soft fillings, and ice cream), and it is sold in defined grades (75\/50 through 85\/55, maltitol \u226550%, sorbitol \u22648.0% in the 75% grade). But its glycemic data (\u224852, insulin index into the 40s for high-polymer grades) means products built on syrup should not carry aggressive net-carb claims, because the community that reads those claims now owns ketone meters. The specification lines that decide this are assay, reducing-sugar residue, hydrogenated oligosaccharide disclosure, and a COA for every batch. A supplier who cannot produce those four lines is selling you a claim risk, not an ingredient.<\/p>\n<h3>Three Label Rules, Three Trust Outcomes<\/h3>\n\n<div class=\"rich-table bd-reveal\">\n <p class=\"rich-table-title\">Net-Carb Accounting: Three Rules and What Each Costs<\/p>\n <div class=\"table-wrapper\">\n <table>\n <thead><tr><th>Rule<\/th><th>Practice<\/th><th>Who uses it<\/th><th>Trust outcome<\/th><\/tr><\/thead>\n <tbody>\n <tr><td data-label=\"Rule\">Full subtraction<\/td><td data-label=\"Practice\">Subtract all sugar-alcohol grams<\/td><td data-label=\"Who uses it\">US “net carb” label convention<\/td><td data-label=\"Trust outcome\">Fastest route to community deconstruction if the polyol is maltitol<\/td><\/tr>\n <tr><td data-label=\"Rule\">Half rule<\/td><td data-label=\"Practice\">Subtract 50% of sugar-alcohol grams<\/td><td data-label=\"Who uses it\">Clinical rule of thumb (Medtronic guidance)<\/td><td data-label=\"Trust outcome\">Conservative; survives scrutiny better<\/td><\/tr>\n <tr><td data-label=\"Rule\">Total carbohydrate<\/td><td data-label=\"Practice\">Count everything<\/td><td data-label=\"Who uses it\">American Diabetes Association guidance<\/td><td data-label=\"Trust outcome\">The only rule with no accounting risk<\/td><\/tr>\n <\/tbody>\n <\/table>\n <\/div>\n <p class=\"rich-table-source\">DataSource: ADA 2026; Medtronic<\/p>\n<\/div>\n<p>The market is already enforcing this. Reddit threads dissect “with stevia” front panels whose second ingredient, listed four separate times, is maltitol; keto reviewers post glucose curves alongside the label math. One comment section at a time, creative label arithmetic is becoming a returns driver rather than a growth tactic.<\/p>\n<h3>Certification Won’t Save a Broken Promise<\/h3>\n<p>The Paleo Foundation did add maltitol to Keto Certified standards, and the keto community’s dominant position did not move (Paleo Foundation, 2020). That gap is the lesson: certification is a gate, not a verdict; the community runs its own trials. The formulation response is not to argue, it is to blend and substitute. Erythritol (GI \u22480) replaces maltitol’s sweetness share in strict-keto SKUs, at the cost of its cooling sensation and its own run of cardiovascular headlines worth tracking. Allulose tests near zero on the glycemic index and draws the best anecdotal glucose profiles in CGM communities, including users who report it lowering their readings. High-intensity sweeteners (stevia, monk fruit) carry sweetness without mass but need blending partners to mask aftertaste. The workhorse strategy is blend-down. Shift 10\u201330% of a formula’s sweetness to a higher-tolerance polyol, and the per-serving maltitol load drops below the threshold where the glycemic argument starts.<\/p>\n\n<div class=\"rich-checklist bd-reveal\">\n <p class=\"rich-checklist-title\"><span class=\"rich-ticon\"><svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"20\" height=\"20\" viewBox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"><path d=\"m3 17 2 2 4-4\"\/><path d=\"m3 7 2 2 4-4\"\/><path d=\"M13 6h8\"\/><path d=\"M13 12h8\"\/><path d=\"M13 18h8\"\/><\/svg><\/span>Specification lines to demand from any maltitol supplier<\/p>\n <ul>\n <li><span class=\"rich-cicon\"><svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"16\" height=\"16\" viewBox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"><circle cx=\"12\" cy=\"12\" r=\"10\"\/><path d=\"m9 12 2 2 4-4\"\/><\/svg><\/span>Assay range on dry basis (expect 98.0\u2013100.5% for crystalline)<\/li>\n <li><span class=\"rich-cicon\"><svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"16\" height=\"16\" viewBox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"><circle cx=\"12\" cy=\"12\" r=\"10\"\/><path d=\"m9 12 2 2 4-4\"\/><\/svg><\/span>Reference standard named (USP \/ BP \/ FCC)<\/li>\n <li><span class=\"rich-cicon\"><svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"16\" height=\"16\" viewBox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"><circle cx=\"12\" cy=\"12\" r=\"10\"\/><path d=\"m9 12 2 2 4-4\"\/><\/svg><\/span>Reducing sugars residue (crystalline grade: \u22640.1%)<\/li>\n <li><span class=\"rich-cicon\"><svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"16\" height=\"16\" viewBox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"><circle cx=\"12\" cy=\"12\" r=\"10\"\/><path d=\"m9 12 2 2 4-4\"\/><\/svg><\/span>Hydrogenated oligosaccharide content disclosed for syrup grades<\/li>\n <li><span class=\"rich-cicon\"><svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"16\" height=\"16\" viewBox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"><circle cx=\"12\" cy=\"12\" r=\"10\"\/><path d=\"m9 12 2 2 4-4\"\/><\/svg><\/span>Sorbitol fraction declared (syrup 75% grade: \u22648.0%)<\/li>\n <li><span class=\"rich-cicon\"><svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"16\" height=\"16\" viewBox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"><circle cx=\"12\" cy=\"12\" r=\"10\"\/><path d=\"m9 12 2 2 4-4\"\/><\/svg><\/span>Per-batch COA, not a one-time spec sheet<\/li>\n <li><span class=\"rich-cicon\"><svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"16\" height=\"16\" viewBox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"><circle cx=\"12\" cy=\"12\" r=\"10\"\/><path d=\"m9 12 2 2 4-4\"\/><\/svg><\/span>Form availability in both crystal and syrup with grade numbers<\/li>\n <\/ul>\n<\/div>\n<h2>Answering the Blood Sugar Question at Scale<\/h2>\n<p>Distributors and importers hear the same three questions on repeat, and each one has a form-qualified answer. “What’s the GI?” is not answerable without asking back: crystalline or syrup, and which application. “Is it keto?” deserves the conditional truth: not for strict keto, self-testable in small crystalline-form portions for liberal low-carb, with erythritol and allulose as the default substitutes for strict lines. “Can diabetics use it?” gets the ADA-aligned answer: lower than sugar, higher than zero-carb sweeteners, count total carbs, and advise downstream brands to label accordingly rather than creatively.

All of them come from real measurements, and none of them is simply wrong. That is the most useful thing to understand about this sweetener. The short answer: crystalline maltitol measures around 36 on the glycemic index, maltitol syrup measures around 52, and sucrose sits near 65 (Saraiva et al., 2020). So yes, maltitol raises blood sugar, but less than sugar does. Everything else worth knowing (why real products refuse to obey the chart, what keto and diabetes communities actually disagree about, and what all of this means for labels and sourcing) hangs off those three numbers. This guide takes them in order.<\/p>\n<h2>What the Number Actually Says, and Why It Comes in Two Versions<\/h2>\n<p>Maltitol is a sugar alcohol (polyol) made by hydrogenating maltose syrup derived from corn or tapioca starch. It delivers roughly 75\u201390% of sucrose’s sweetness at about 2.1 kcal per gram, does not promote tooth decay, and is approved in major markets including the EU (as E 965) (Saraiva et al., 2020). One disambiguation before anything else: maltitol is not maltodextrin. Maltodextrin is a starch-derived glucose polymer that scores near the very top of the glycemic scale, close to pure glucose (GI 100 by definition of the scale). The two names collide constantly in comment sections, and they behave nothing alike. Everything below is about maltitol, the polyol.<\/p>\n\n<div class=\"bp-1-hook bd-reveal\">\n <p class=\"bp-1-hook-quote\"><span class=\"bp-1-hook-icon\"><svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"22\" height=\"22\" viewBox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"><path d=\"M16 3a2 2 0 0 0-2 2v6a2 2 0 0 0 2 2 1 1 0 0 1 1 1v1a2 2 0 0 1-2 2 1 1 0 0 0-1 1v2a1 1 0 0 0 1 1 6 6 0 0 0 6-6V5a2 2 0 0 0-2-2z\"\/><path d=\"M5 3a2 2 0 0 0-2 2v6a2 2 0 0 0 2 2 1 1 0 0 1 1 1v1a2 2 0 0 1-2 2 1 1 0 0 0-1 1v2a1 1 0 0 0 1 1 6 6 0 0 0 6-6V5a2 2 0 0 0-2-2z\"\/><\/svg><\/span><span class=\"bp-1-hook-key\">36 vs 52<\/span>: one ingredient name, two glycemic answers, 16 points apart. The form of maltitol on the label decides which answer applies.<\/p>\n<\/div>\n<p>Why two answers for one name? Crystalline maltitol is a high-purity single molecule (specification-grade powder assays at 98%+ maltitol), and it measures GI \u224836. Maltitol syrup is not diluted crystalline maltitol. Commercial syrup grades carry roughly half or more of their solids as maltitol, together with a significant fraction of hydrogenated oligosaccharides (larger hydrogenated saccharides) and a controlled sorbitol fraction (\u22648.0% in the common 75% grade). Those hydrogenated oligosaccharides are what push the syrup’s GI up to 52 (Saraiva et al., 2020). The popular claim that maltitol has “about half the glycemic impact of sugar” is accurate for the crystalline form (36 vs ~65) and optimistic for syrup, which lands closer to two-thirds of sugar’s impact.<\/p>\n<p>Context helps, so here is maltitol against the sweeteners it usually shares a label with. Treat these as published approximations: exact values vary by study, method, and form.<\/p>\n\n<div class=\"rich-table bd-reveal\">\n <p class=\"rich-table-title\">Common Sweeteners by Glycemic Index (published approximations)<\/p>\n <div class=\"table-wrapper\">\n <table>\n <thead><tr><th>Sweetener<\/th><th>GI (approx.)<\/th><th>Note<\/th><\/tr><\/thead>\n <tbody>\n <tr><td data-label=\"Sweetener\">Erythritol<\/td><td data-label=\"GI (approx.)\">~0<\/td><td data-label=\"Note\">Excreted unchanged; best-in-class glycemic profile<\/td><\/tr>\n <tr><td data-label=\"Sweetener\">Lactitol<\/td><td data-label=\"GI (approx.)\">~6<\/td><td data-label=\"Note\">Polyol<\/td><\/tr>\n <tr><td data-label=\"Sweetener\">Isomalt<\/td><td data-label=\"GI (approx.)\">~9<\/td><td data-label=\"Note\">Polyol<\/td><\/tr>\n <tr><td data-label=\"Sweetener\">Sorbitol<\/td><td data-label=\"GI (approx.)\">~9<\/td><td data-label=\"Note\">Polyol<\/td><\/tr>\n <tr><td data-label=\"Sweetener\">Xylitol<\/td><td data-label=\"GI (approx.)\">~13<\/td><td data-label=\"Note\">Polyol<\/td><\/tr>\n <tr><td data-label=\"Sweetener\">Maltitol (crystalline)<\/td><td data-label=\"GI (approx.)\">~36<\/td><td data-label=\"Note\">Highest-GI common polyol<\/td><\/tr>\n <tr><td data-label=\"Sweetener\">Maltitol syrup<\/td><td data-label=\"GI (approx.)\">~52<\/td><td data-label=\"Note\">Hydrogenated oligosaccharides push it up<\/td><\/tr>\n <tr><td data-label=\"Sweetener\">Sucrose<\/td><td data-label=\"GI (approx.)\">~65<\/td><td data-label=\"Note\">Reference<\/td><\/tr>\n <\/tbody>\n <\/table>\n <\/div>\n <p class=\"rich-table-source\">DataSource: Saraiva et al. 2020; GoodRx 2024; KetoConnect<\/p>\n<\/div>\n<p>If you have seen figures from 29 to 52 attached to maltitol, you now know where they come from: different forms, different assay methods, different eras of testing. They all collapse into the form-qualified pair above. (Maltitol’s other famous issue, digestive distress, is a separate dose-dependent story with its own thresholds; it is covered in a <a href=\"https:\/\/www.saigaoingredients.com\/blogs\/safety-and-tolerability-of-maltitol-syrup\/\">separate guide to maltitol’s digestive tolerance<\/a>.)<\/p>\n<p>The number is now qualified. The next question is why your own glucose curve sometimes refuses to follow it.<\/p>\n<h2>Why Real Products Don’t Match the Chart<\/h2>\n<p>A GI value is measured under standardized conditions: 50 grams of available carbohydrate, fasting subjects, blood sampled at fixed intervals for two hours. Real life violates every one of those conditions at once, in four predictable ways.<\/p>\n<h3>The Dose and the Carrier<\/h3>\n<p>The 50-gram standard matters because dose and vehicle drive the response. In a controlled trial, a single 50 g dose of maltitol produced significantly lower glucose and insulin responses than the same dose of sucrose in healthy young subjects (Msomi et al., 2021). Change the dose or the matrix, though, and the picture shifts. Fat and protein in a chocolate or ice-cream base slow gastric emptying and flatten the curve; a gummy carrier does not. Continuous glucose monitor (CGM) users report the same brand of sugar-free chocolate spiking them hard in the caramel variety and barely registering in the mint variety from the same package line: the filling changed the response, not the sweetener listed on the front. Serving-size accounting does the rest of the damage. Community threads are full of people who treated a small container as one serving and doubled the intended polyol load, then spent months blaming their A1C trajectory on everything else.<\/p>\n<h3>Crystal vs. Syrup: the Material Difference<\/h3>\n<p>The form effect from the first section has a material basis, and it shows up in more than one metric. The glycemic spread (crystalline \u224836, syrup \u224852) tracks the hydrogenated oligosaccharide content of the syrup (Saraiva et al., 2020). The insulin index spreads the same way: pure maltitol measures around 27, while high-polymer maltitol syrups can reach the mid-40s (Paleo Foundation, 2020). That matters most for keto readers, because insulin is the hormone that suppresses ketone production. For formulators, form is the first glycemic lever available: same sweetener family, same sweetness ballpark, measurably different metabolic signature. For shoppers, the practical rule is that “maltitol” on an ingredient list can mean either material, and maltitol syrup is the one to expect more from.<\/p>\n\n <img decoding=\"async\" src=\"https:\/\/www.saigaoingredients.com\/wp-content\/uploads\/2026\/09\/Maltitol-Glycemic-Index.webp\" style=\"width: 512px; height: 384px; max-width: 100%; object-fit: cover; border-radius: 12px; margin: 30px auto; display: block; box-shadow: 10px 10px 60px 0px rgba(210, 221, 224, 0.35); transition: all 0.3s ease; cursor: pointer;\" onmouseover=\"this.style.transform='translateY(-5px) scale(1.03)'; this.style.boxShadow='15px 25px 80px 0px rgba(210, 221, 224, 0.45)'\" onmouseout=\"this.style.transform='translateY(0) scale(1)'; this.style.boxShadow='10px 10px 60px 0px rgba(210, 221, 224, 0.35)'\"> \n\n<h3>The Net-Carb Accounting Problem<\/h3>\n<p>Labels feed the confusion. In US practice, manufacturers subtract sugar alcohols from total carbohydrate when calculating “net carbs,” as if all polyols behaved like erythritol. Maltitol does not. A common clinical rule of thumb is to subtract only half the sugar-alcohol grams; the American Diabetes Association sidesteps the debate entirely and instructs people with diabetes to count total carbohydrate (American Diabetes Association, 2026; Medtronic). Run the arithmetic on a bar that advertises 2g net carbs from 18g of maltitol and you get something that behaves like roughly 9\u201315g of ordinary carbohydrate, depending on form and individual response. The label number is not a lie, but it is an accounting choice, not a metabolic measurement.<\/p>\n<p>Put the four variables together and each deviation from the chart becomes diagnosable.<\/p>\n\n<div class=\"rich-table bd-reveal\">\n <p class=\"rich-table-title\">Why Your Glucose Response Differs From the GI Chart<\/p>\n <div class=\"table-wrapper\">\n <table>\n <thead><tr><th>Serving scenario<\/th><th>Form basis<\/th><th>Expected response<\/th><th>What to do<\/th><\/tr><\/thead>\n <tbody>\n <tr><td data-label=\"Serving scenario\">Small portion (\u226410g maltitol), taken with a meal<\/td><td data-label=\"Form basis\">Either<\/td><td data-label=\"Expected response\">Mild, slow rise; often hard to distinguish from noise<\/td><td data-label=\"What to do\">Standard tolerance zone for most people<\/td><\/tr>\n <tr><td data-label=\"Serving scenario\">Typical serving (10\u201325g) of crystalline-based product<\/td><td data-label=\"Form basis\">Crystalline<\/td><td data-label=\"Expected response\">Modest rise on the GI \u224836 pattern<\/td><td data-label=\"What to do\">Reasonable; verify with CGM if diabetic or strict keto<\/td><\/tr>\n <tr><td data-label=\"Serving scenario\">Typical serving of syrup-based confectionery<\/td><td data-label=\"Form basis\">Syrup<\/td><td data-label=\"Expected response\">Earlier, higher rise on the GI \u224852 pattern<\/td><td data-label=\"What to do\">Check the ingredient list; expect more from this form<\/td><\/tr>\n <tr><td data-label=\"Serving scenario\">Whole-container or repeated servings (30g+ polyol)<\/td><td data-label=\"Form basis\">Either<\/td><td data-label=\"Expected response\">Response approaches sugar territory as dose stacks<\/td><td data-label=\"What to do\">Count it as real carbohydrate (digestive limits arrive separately)<\/td><\/tr>\n <\/tbody>\n <\/table>\n <\/div>\n <p class=\"rich-table-source\">DataSource: Conditions synthesized from Saraiva et al. 2020; Msomi et al. 2021; ADA guidance; CGM user reports<\/p>\n<\/div>\n<h2>Keto and Diabetes: Same Number, Different Verdicts<\/h2>\n<p>Ask the keto question and you get three defensible answers that contradict each other. Diet Doctor tells readers to avoid maltitol outright (Diet Doctor, 2026). KetoConnect put 50 grams of maltitol syrup to a fingerstick test and watched blood sugar climb about 40 points in 30 minutes, concluding it is “a major no-no” (KetoConnect). MedicineNet, at the other end, describes maltitol’s rise as small, slow, and gradual. Meanwhile the Paleo Foundation reviewed the top-ranking “maltitol keto” content in 2019, found roughly 80% of it negative, disagreed with the majority’s reasoning, and formally added maltitol to its Keto Certified standards (Paleo Foundation, 2020). The camps are not arguing about the data; they are optimizing different things. Keto optimizes ketone production, which insulin suppresses, so form and dose decide: 50g of syrup form will threaten ketosis, while a small crystalline-form portion in a mixed, low-carb day may not register at all. The working verdict: strict keto has better tools and rarely needs to take the risk; liberal low-carb eaters can self-test small portions and decide on their own data.<\/p>\n<p>Ask the diabetes question and the split repeats at higher stakes. Diabetes.co.uk calls maltitol “beneficial for people with diabetes” because it produces lower glucose and insulin rises than sugar (Diabetes.co.uk, 2023). ConsumerLab concludes it is “not a problematic ingredient” for type 2 diabetes (ConsumerLab). A widely upvoted r\/prediabetes post argues the opposite: treat maltitol-sweetened products as neither sugar-free nor low-glycemic. All three are defensible because they compare maltitol against different baselines. Against sugar, maltitol is genuinely lower (Msomi et al., 2021). Against zero-carb sweeteners like erythritol, stevia, or allulose, it is genuinely higher. Between those baselines sits enormous individual variance, which is why the ADA skips the category debate and tells people to count total carbohydrate and watch their own readings. Note what “diabetic-friendly” on a front panel does and does not mean: it is a marketing phrase, not a clinical license.<\/p>\n\n<div class=\"rich-table bd-reveal\">\n <p class=\"rich-table-title\">Two Frameworks, Two Working Verdicts<\/p>\n <div class=\"table-wrapper\">\n <table>\n <thead><tr><th>Framework<\/th><th>What it optimizes<\/th><th>Where maltitol lands<\/th><th>Working verdict<\/th><\/tr><\/thead>\n <tbody>\n <tr><td data-label=\"Framework\">Strict keto<\/td><td data-label=\"What it optimizes\">Ketone maintenance (insulin-sensitive)<\/td><td data-label=\"Where maltitol lands\">Worst common polyol on glycemia and insulin index; syrup form far worse<\/td><td data-label=\"Working verdict\">Prefer erythritol, allulose, stevia, monk fruit<\/td><\/tr>\n <tr><td data-label=\"Framework\">Liberal low-carb<\/td><td data-label=\"What it optimizes\">Carb minimization with flexibility<\/td><td data-label=\"Where maltitol lands\">Moderate impact, dose- and form-dependent<\/td><td data-label=\"Working verdict\">Self-test small crystalline-form portions; keep syrup-form out<\/td><\/tr>\n <tr><td data-label=\"Framework\">Type 2 diabetes<\/td><td data-label=\"What it optimizes\">Post-meal glucose control<\/td><td data-label=\"Where maltitol lands\">Lower than sugar, higher than zero-carb sweeteners<\/td><td data-label=\"Working verdict\">Count total carbs (ADA), watch your own response, treat “diabetic-friendly” as marketing<\/td><\/tr>\n <\/tbody>\n <\/table>\n <\/div>\n <p class=\"rich-table-source\">DataSource: Verdicts synthesized from sources cited in text<\/p>\n<\/div>\n<p>Both frameworks converge on the same exit, which is the only part of this argument that never goes stale: measure your own response.<\/p>\n\n<div class=\"rich-steps bd-reveal\">\n <p class=\"rich-steps-title\"><span class=\"rich-ticon\"><svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"20\" height=\"20\" viewBox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"><circle cx=\"6\" cy=\"19\" r=\"3\"\/><path d=\"M9 19h8.5a3.5 3.5 0 0 0 0-7h-11a3.5 3.5 0 0 1 0-7H15\"\/><circle cx=\"18\" cy=\"5\" r=\"3\"\/><\/svg><\/span>The self-test protocol<\/p>\n <div class=\"rich-steps-list\">\n <div class=\"rich-steps-item\"><span class=\"rich-steps-chip\">1<\/span><p class=\"rich-steps-text\">Pick one product and one fixed portion; do not change two variables at once.<\/p><\/div>\n <div class=\"rich-steps-item\"><span class=\"rich-steps-chip\">2<\/span><p class=\"rich-steps-text\">Test it fasting once and with a meal once; the difference is often larger than the sweetener effect.<\/p><\/div>\n <div class=\"rich-steps-item\"><span class=\"rich-steps-chip\">3<\/span><p class=\"rich-steps-text\">Repeat 2\u20133 times before concluding; single readings mislead.<\/p><\/div>\n <div class=\"rich-steps-item\"><span class=\"rich-steps-chip\">4<\/span><p class=\"rich-steps-text\">Keto readers add a ketone check 2\u20133 hours after; some users watch ketones dip for hours after syrup-form products.<\/p><\/div>\n <div class=\"rich-steps-item\"><span class=\"rich-steps-chip\">5<\/span><p class=\"rich-steps-text\">Log the form (crystal or syrup) next to the result; the same brand name can hide different materials.<\/p><\/div>\n <\/div>\n <p class=\"rich-steps-note\">Note: individual reports cover both extremes (six-week CGM users flat “like eating chicken,” self-testers up 40 points in 30 minutes).

Its specification language is mature: ask for assay 98.0\u2013100.5% (dry basis), reducing sugars \u22640.1%, and conductivity \u226420 \u00b5S\/cm, referenced to USP\/BP\/FCC. That is the grade behind the GI \u224836 data. Maltitol syrup exists for a reason (it inhibits crystallization in hard candy, soft fillings, and ice cream), and it is sold in defined grades (75\/50 through 85\/55, maltitol \u226550%, sorbitol \u22648.0% in the 75% grade). But its glycemic data (\u224852, insulin index into the 40s for high-polymer grades) means products built on syrup should not carry aggressive net-carb claims, because the community that reads those claims now owns ketone meters. The specification lines that decide this are assay, reducing-sugar residue, hydrogenated oligosaccharide disclosure, and a COA for every batch. A supplier who cannot produce those four lines is selling you a claim risk, not an ingredient.<\/p>\n<h3>Three Label Rules, Three Trust Outcomes<\/h3>\n\n<div class=\"rich-table bd-reveal\">\n <p class=\"rich-table-title\">Net-Carb Accounting: Three Rules and What Each Costs<\/p>\n <div class=\"table-wrapper\">\n <table>\n <thead><tr><th>Rule<\/th><th>Practice<\/th><th>Who uses it<\/th><th>Trust outcome<\/th><\/tr><\/thead>\n <tbody>\n <tr><td data-label=\"Rule\">Full subtraction<\/td><td data-label=\"Practice\">Subtract all sugar-alcohol grams<\/td><td data-label=\"Who uses it\">US “net carb” label convention<\/td><td data-label=\"Trust outcome\">Fastest route to community deconstruction if the polyol is maltitol<\/td><\/tr>\n <tr><td data-label=\"Rule\">Half rule<\/td><td data-label=\"Practice\">Subtract 50% of sugar-alcohol grams<\/td><td data-label=\"Who uses it\">Clinical rule of thumb (Medtronic guidance)<\/td><td data-label=\"Trust outcome\">Conservative; survives scrutiny better<\/td><\/tr>\n <tr><td data-label=\"Rule\">Total carbohydrate<\/td><td data-label=\"Practice\">Count everything<\/td><td data-label=\"Who uses it\">American Diabetes Association guidance<\/td><td data-label=\"Trust outcome\">The only rule with no accounting risk<\/td><\/tr>\n <\/tbody>\n <\/table>\n <\/div>\n <p class=\"rich-table-source\">DataSource: ADA 2026; Medtronic<\/p>\n<\/div>\n<p>The market is already enforcing this. Reddit threads dissect “with stevia” front panels whose second ingredient, listed four separate times, is maltitol; keto reviewers post glucose curves alongside the label math. One comment section at a time, creative label arithmetic is becoming a returns driver rather than a growth tactic.<\/p>\n<h3>Certification Won’t Save a Broken Promise<\/h3>\n<p>The Paleo Foundation did add maltitol to Keto Certified standards, and the keto community’s dominant position did not move (Paleo Foundation, 2020). That gap is the lesson: certification is a gate, not a verdict; the community runs its own trials. The formulation response is not to argue, it is to blend and substitute. Erythritol (GI \u22480) replaces maltitol’s sweetness share in strict-keto SKUs, at the cost of its cooling sensation and its own run of cardiovascular headlines worth tracking. Allulose tests near zero on the glycemic index and draws the best anecdotal glucose profiles in CGM communities, including users who report it lowering their readings. High-intensity sweeteners (stevia, monk fruit) carry sweetness without mass but need blending partners to mask aftertaste. The workhorse strategy is blend-down. Shift 10\u201330% of a formula’s sweetness to a higher-tolerance polyol, and the per-serving maltitol load drops below the threshold where the glycemic argument starts.<\/p>\n\n<div class=\"rich-checklist bd-reveal\">\n <p class=\"rich-checklist-title\"><span class=\"rich-ticon\"><svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"20\" height=\"20\" viewBox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"><path d=\"m3 17 2 2 4-4\"\/><path d=\"m3 7 2 2 4-4\"\/><path d=\"M13 6h8\"\/><path d=\"M13 12h8\"\/><path d=\"M13 18h8\"\/><\/svg><\/span>Specification lines to demand from any maltitol supplier<\/p>\n <ul>\n <li><span class=\"rich-cicon\"><svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"16\" height=\"16\" viewBox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"><circle cx=\"12\" cy=\"12\" r=\"10\"\/><path d=\"m9 12 2 2 4-4\"\/><\/svg><\/span>Assay range on dry basis (expect 98.0\u2013100.5% for crystalline)<\/li>\n <li><span class=\"rich-cicon\"><svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"16\" height=\"16\" viewBox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"><circle cx=\"12\" cy=\"12\" r=\"10\"\/><path d=\"m9 12 2 2 4-4\"\/><\/svg><\/span>Reference standard named (USP \/ BP \/ FCC)<\/li>\n <li><span class=\"rich-cicon\"><svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"16\" height=\"16\" viewBox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"><circle cx=\"12\" cy=\"12\" r=\"10\"\/><path d=\"m9 12 2 2 4-4\"\/><\/svg><\/span>Reducing sugars residue (crystalline grade: \u22640.1%)<\/li>\n <li><span class=\"rich-cicon\"><svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"16\" height=\"16\" viewBox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"><circle cx=\"12\" cy=\"12\" r=\"10\"\/><path d=\"m9 12 2 2 4-4\"\/><\/svg><\/span>Hydrogenated oligosaccharide content disclosed for syrup grades<\/li>\n <li><span class=\"rich-cicon\"><svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"16\" height=\"16\" viewBox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"><circle cx=\"12\" cy=\"12\" r=\"10\"\/><path d=\"m9 12 2 2 4-4\"\/><\/svg><\/span>Sorbitol fraction declared (syrup 75% grade: \u22648.0%)<\/li>\n <li><span class=\"rich-cicon\"><svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"16\" height=\"16\" viewBox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"><circle cx=\"12\" cy=\"12\" r=\"10\"\/><path d=\"m9 12 2 2 4-4\"\/><\/svg><\/span>Per-batch COA, not a one-time spec sheet<\/li>\n <li><span class=\"rich-cicon\"><svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"16\" height=\"16\" viewBox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"><circle cx=\"12\" cy=\"12\" r=\"10\"\/><path d=\"m9 12 2 2 4-4\"\/><\/svg><\/span>Form availability in both crystal and syrup with grade numbers<\/li>\n <\/ul>\n<\/div>\n<h2>Answering the Blood Sugar Question at Scale<\/h2>\n<p>Distributors and importers hear the same three questions on repeat, and each one has a form-qualified answer. “What’s the GI?” is not answerable without asking back: crystalline or syrup, and which application. “Is it keto?” deserves the conditional truth: not for strict keto, self-testable in small crystalline-form portions for liberal low-carb, with erythritol and allulose as the default substitutes for strict lines. “Can diabetics use it?” gets the ADA-aligned answer: lower than sugar, higher than zero-carb sweeteners, count total carbs, and advise downstream brands to label accordingly rather than creatively.
