The Best and Worst Sweeteners Ranked by GI Index

Why Glycemic Index Matters When Choosing a Sweetener

When you are trying to cut back on added sugar, lose weight, or manage blood sugar, the type of sweetener you choose matters just as much as the amount. One of the most useful tools for comparing sweeteners is the glycemic index (GI) – a scale that estimates how quickly a carbohydrate-containing food raises blood glucose.

In this guide, we will walk through common sweeteners ranked by GI index, from highest to lowest, and discuss what that means in real life. We will also highlight why MonkVee monk fruit sweetener, a 100% natural, zero-calorie, zero-glycemic option, is an excellent choice if you want sweetness without the blood sugar spike.

Quick Refresher: What Is Glycemic Index?

The glycemic index ranks carbohydrate foods on a scale of 0 to 100 based on how quickly they raise blood sugar after eating. It is usually measured by giving people a fixed amount of carbohydrate from a test food and comparing their blood sugar response to the same amount of carbohydrate from pure glucose (GI = 100).

• High GI: 70 or higher – raises blood sugar quickly.


• Medium GI: 56–69 – moderate effect.


• Low GI: 55 or lower – slower, more gradual effect.


• Zero GI: 0 – essentially no measurable impact on blood glucose.

GI is one piece of the puzzle. It does not tell the whole story (for example, it does not include portion size or total carbs), but it is a helpful way to compare sweeteners side by side.

How We Ranked These Sweeteners

This ranking focuses on glycemic index first, and then considers:

• Typical impact on blood sugar and insulin.


• Calorie content and carbohydrate load.


• How they are commonly used in everyday life.

Numbers are approximate because GI can vary between studies, brands, and preparation methods, but the big picture remains consistent.

High-GI Sweeteners: Big, Fast Blood Sugar Spikes

1. Glucose / Dextrose (GI ~100)

Glucose (also known as dextrose) is the reference point for the GI scale and is assigned a value of 100. It is rapidly absorbed and causes a sharp rise in blood sugar and insulin.

Common uses: sports drinks, energy gels, some candies, processed foods, and as a pure powder for baking or medical use.

Takeaway: Effective when a rapid blood sugar rise is needed (for example, in treating hypoglycemia under medical guidance), but not ideal as an everyday sweetener if you are aiming for stable blood sugar or weight management.

2. Maltose (GI ~105)

Maltose is a disaccharide made of two glucose molecules. It is found in malted products and some syrups.

Common uses: brewing, some cereals and candies, malted milk powders.

Takeaway: Very high GI; it behaves similarly to or even more rapidly than glucose in terms of blood sugar impact.

3. White Table Sugar (Sucrose) (GI ~60–65)

Sucrose (table sugar) is a combination of glucose and fructose. Its GI is lower than pure glucose but still in the moderate-to-high range.

Common uses: baking, beverages, desserts, sauces, and nearly all conventional sweet snacks.

Takeaway: Sucrose is energy-dense (about 4 kcal per gram) and can significantly raise blood sugar and insulin when used in typical serving sizes. Reducing added sucrose is a central recommendation in most nutrition and diabetes guidelines.

4. High-Fructose Corn Syrup (HFCS) (GI ~55–65)

High-fructose corn syrup is a common sweetener in soft drinks and processed foods. Its GI is similar to or slightly lower than sucrose, depending on the fructose-to-glucose ratio.

Common uses: sodas, sweetened beverages, packaged snacks, condiments, and many commercial baked goods.

Takeaway: HFCS behaves similarly to table sugar in terms of blood sugar response and overall metabolic impact when consumed in typical amounts. From a GI perspective, it is not a lower-impact alternative to sugar.

Medium-GI Sweeteners: Slightly Gentler, Still Significant

5. Honey (GI ~50–70, varies)

Honey contains a mix of fructose, glucose, and other compounds. Its GI varies widely by floral source and processing.

Common uses: tea, baking, marinades, dressings, and “natural” sweet recipes.

Takeaway: Honey is often perceived as healthier than sugar, and it does contain trace antioxidants and other bioactive compounds. However, from a blood sugar standpoint, it still provides substantial carbohydrate and can raise glucose and insulin significantly, especially in larger amounts.

6. Coconut Sugar (GI ~50–54)

Coconut sugar is made from the sap of coconut palm flower buds. It contains sucrose, small amounts of fructose and glucose, and trace minerals.

Common uses: baking, coffee, and as a “natural” swap for white sugar.

Takeaway: Its GI is somewhat lower than table sugar, but it is still a concentrated source of carbohydrates and calories. It does not behave like a low- or zero-GI sweetener.

7. Maple Syrup (GI ~54)

Maple syrup is primarily sucrose with some water and trace minerals.

Common uses: pancakes, waffles, baking, sauces, and glazes.

Takeaway: Slightly lower GI than sugar but still delivers a significant carbohydrate load. It should be used in moderation, especially for people monitoring blood sugar.

Low-GI Sweeteners: Gentler on Blood Sugar

8. Agave Syrup (GI ~10–30, varies)

Agave syrup is often marketed as low GI because it contains a high proportion of fructose, which has a lower immediate effect on blood glucose.

Common uses: beverages, baking, and as a liquid sweetener for “natural” products.

Takeaway: While its GI can be lower than many other sugars, agave is still high in total sugars and calories. Fructose is handled differently by the body than glucose, and high intakes of added fructose are not generally recommended. From a GI perspective, it is lower, but it is still an added sugar.

9. Sugar Alcohols (Polyols) – Variable GI

Sugar alcohols (polyols) are a diverse group, and their GI values vary:

• Maltitol: GI ~35 (can raise blood sugar moderately).


• Xylitol: GI ~7–13 (lower effect).


• Sorbitol: GI ~4–9 (low effect).


• Erythritol: GI ~0 (essentially no effect).

Common uses: sugar-free candies, chewing gum, baked goods, and some tabletop sweeteners.

Takeaway: Polyols generally have fewer calories than sugar and a lower glycemic impact, especially erythritol, which is essentially non-glycemic. Some people experience digestive discomfort with higher amounts of certain polyols (like maltitol or sorbitol), so portion size and individual tolerance matter.

Zero-GI Sweeteners: Minimal to No Blood Sugar Impact

10. Monk Fruit Sweetener (Luo Han Guo) – GI ~0

Monk fruit sweetener is derived from the fruit of Siraitia grosvenorii, traditionally used in parts of Asia. The intense sweetness comes from compounds called mogrosides, which are non-nutritive (they provide essentially no calories).

Glycemic index: Monk fruit extract itself has a GI of approximately 0 because it contributes negligible digestible carbohydrate and does not meaningfully raise blood sugar.

Common uses: tabletop sweeteners, baking blends, beverages, yogurt, and a wide range of reduced-sugar or sugar-free products.

Takeaway: Monk fruit is an excellent option if you are aiming for near-zero blood sugar impact while still enjoying sweetness. It is generally well-tolerated, and current research supports its use as a non-caloric sweetener when used within normal amounts.

Why MonkVee Monk Fruit Stands Out

MonkVee monk fruit sweetener is formulated to provide clean, natural sweetness with zero calories and zero glycemic impact, making it particularly suitable for:

• People living with diabetes or prediabetes (as part of an overall care plan).


• Those practicing low-carb, keto, or carb-conscious eating patterns.


• Anyone looking to significantly reduce or eliminate added sugars without giving up sweetness.

Because monk fruit is so intensely sweet, MonkVee sweeteners are carefully balanced to mimic the sweetness level of sugar, making it easier to substitute in recipes and beverages without constant recalculation.

11. Stevia – GI ~0

Stevia is extracted from the leaves of Stevia rebaudiana. The sweet compounds (steviol glycosides) are non-caloric and do not significantly affect blood sugar.

Glycemic index: Approximately 0 for purified steviol glycosides, though blended products may contain small amounts of carbohydrate depending on the formulation.

Common uses: tabletop sweeteners, beverages, yogurts, and many sugar-free products.

Takeaway: Stevia is another well-studied, zero-GI sweetener option. Some people notice a characteristic aftertaste, while others do not. It can be used alongside monk fruit or other sweeteners to create a more sugar-like taste profile.

12. Erythritol – GI ~0

Erythritol is a sugar alcohol that the body absorbs but does not metabolize for energy, so it is excreted largely unchanged.

Glycemic index: Approximately 0 – it has minimal impact on blood glucose or insulin in most people.

Common uses: baking blends, tabletop sweeteners, sugar-free chocolates, and many reduced-sugar products.

Takeaway: Erythritol provides bulk and texture similar to sugar with very low calories and essentially no glycemic effect. As with other polyols, individual tolerance can vary, but it is generally well-tolerated at typical intake levels.

Putting It Together: Ranking Sweeteners by GI Index

Medically Responsible Use of Low- and Zero-GI Sweeteners

Even with zero-GI options, a few principles remain important:

• They are tools, not cures. Replacing sugar with low- or zero-GI sweeteners can support blood sugar management, but it does not replace comprehensive care for conditions like diabetes or metabolic syndrome.


• Whole diet matters. Emphasizing vegetables, high-fiber foods, lean proteins, and healthy fats remains essential, regardless of which sweetener you choose.


• Listen to your body. People vary in taste preferences and digestive tolerance. It is reasonable to experiment and see which sweeteners feel best for you.


• Work with your healthcare team. If you have diabetes, prediabetes, or other metabolic conditions, discuss any major dietary changes with your healthcare provider or dietitian, especially if you use medications that affect blood sugar.

How to Transition Away from High-GI Sweeteners

Step 1: Identify Your Biggest Sugar Sources

Most people get the bulk of their added sugar from a few key places:

• Sugary drinks (soda, sweetened coffee drinks, energy drinks, juices).


• Desserts and baked goods (cookies, cakes, pastries).


• Everyday “extras” (sugar in coffee or tea, sweetened yogurt, breakfast cereals, condiments).

Start by looking at where you add sugar automatically and where it would be easiest to swap in a zero-GI option.

Step 2: Make Simple Swaps with MonkVee Monk Fruit

• Coffee and tea: Replace table sugar or honey with MonkVee monk fruit sweetener. Adjust gradually to find your preferred sweetness level.


• Oatmeal and yogurt: Use MonkVee instead of brown sugar, maple syrup, or flavored syrups. Add fruit for extra flavor and fiber.


• Home baking: Experiment with MonkVee monk fruit sweetener in muffins, quick breads, and cookies. Start with recipes where texture is less critical, and adjust over time.

Step 3: Read Labels on Packaged Foods

Even if you swap out sugar at home, packaged foods can still be major sources of high-GI sweeteners. Look for:

• “Added sugars” on the Nutrition Facts panel.


• Ingredients like sugar, high-fructose corn syrup, cane sugar, brown rice syrup, and other syrups high on the ingredient list.


• Products that use low- or zero-GI sweeteners such as monk fruit, stevia, or erythritol in place of large amounts of added sugar.

Key Takeaways

GI Ranking in Context

• High-GI sweeteners like glucose, maltose, table sugar, and HFCS raise blood sugar quickly and substantially.


• Medium-GI sweeteners like honey, coconut sugar, and maple syrup still deliver significant carbohydrate and should be used in moderation.


• Low-GI options like some sugar alcohols and agave have a gentler effect but still contribute calories and total carbohydrate.


• Zero-GI sweeteners such as monk fruit, stevia, and erythritol have minimal to no impact on blood sugar and can be valuable tools for reducing added sugar intake.

Within the zero-GI group, MonkVee monk fruit sweetener offers a natural, calorie-free way to enjoy sweetness with essentially no glycemic impact, making it an excellent choice when your priority is stabilizing blood sugar while still living a delicious, sustainable lifestyle.

If you are ready to lower your overall glycemic load and cut back on added sugars, exploring monk fruit-based sweeteners is a scientifically grounded, practical place to start.
