4 min read

Many Think bar varieties are advertised as having 0 grams of sugar, but their total carbohydrate content and use of sweeteners can vary significantly across product lines. The amount of sugar in a Think bar depends on the specific bar you choose, with certain types containing 0g of total sugars while others have a small amount.

Quick Summary

The total sugar content of Think bars ranges from 0g to 2g, depending on the specific product line. High-protein bars often contain 0g sugar but use sugar alcohols like maltitol for sweetness. Other varieties, including Keto and Crisp bars, may contain 1-2g of total sugar. The use of sugar alcohols can impact net carb count and digestive health.

Key Points

Varies by Type: The sugar content in a Think bar is not uniform and depends on the specific product line, such as High Protein, Delight, or Plant-Based.
0g Sugar (with Sugar Alcohols): Many Think High Protein bars contain 0 grams of total sugar but use sugar alcohols like maltitol for sweetness.
Mindful of Sugar Alcohols: Consumers sensitive to sugar alcohols should be cautious, as ingredients like maltitol can cause digestive discomfort.
Keto-Friendly Option: Think's Delight bars are keto-certified and have a low net carb count, featuring around 1-2 grams of sugar.
Ingredient-Conscious Choice: Always check the nutrition facts on the specific bar's packaging to understand its sugar, sugar alcohol, and overall carbohydrate content.
Impact on Blood Sugar: Despite having zero grams of sugar, the sugar alcohols in many bars still impact blood sugar levels, which is important for those managing diabetes.

Understanding the Sugar Content in Think Bars

Think bars have built a reputation for offering high-protein, low-sugar snacking options, but their nutritional profile isn't one-size-fits-all. The amount of sugar in a Think bar can differ based on the specific type, such as the High Protein line versus the Delight or Plant-Based varieties. It is crucial to read the nutritional facts for the exact bar you are considering, as the total sugar count is not consistent across all products.

The '0g Sugar' Claim vs. Reality

Many of Think's High Protein bars famously state '0g sugar' on the packaging. This claim is technically accurate in that they contain no added sugar and no total sugars, but it is achieved by using sugar alcohols. Ingredients like maltitol syrup and erythritol are used to provide a sweet flavor without contributing to the total sugar count. While these sweeteners offer a lower calorie count and glycemic impact than traditional sugar, they are carbohydrates and should be factored into overall intake.

Maltitol: A sugar alcohol that is lower in calories than sugar but can cause digestive upset, such as gas or bloating, in some individuals. It is frequently found in the High Protein line.
Erythritol: Another sugar alcohol used in Think bars, particularly the keto-friendly 'Delight' range. It is generally better tolerated by the digestive system than maltitol.
Natural Sweeteners: Think also uses other natural sweeteners like stevia and monk fruit in various products, which do not contribute to sugar or calorie counts.

Varieties of Think Bars and Their Sugar Content

Think offers a diverse lineup of bars, and their nutritional makeup, particularly the sugar and sugar alcohol content, can vary widely. Shoppers should pay close attention to which bar they're selecting to ensure it aligns with their dietary goals.

High Protein Bars: As mentioned, many of these flavors like Creamy Peanut Butter and Brownie Crunch contain 0g of total sugars, relying on sugar alcohols.
Keto-Friendly Delight Bars: Designed for a low-carb diet, these bars typically contain a very low amount of total sugar. The Chocolate Peanut Butter Pie flavor, for instance, has just 1g or 2g of total sugar and only 3-4g of net carbs.
Plant-Based Bars: These are formulated with pea, brown rice, and pumpkin protein and also aim for a low sugar profile. The specific sugar content will depend on the flavor and other ingredients.
Crisp Bars: A lighter option, these bars contain a different blend of ingredients. For example, some crisp bar varieties contain 2g of total sugar.

A Comparative Look: Think Bars vs. Competitors

To put the sugar content of Think bars into perspective, it helps to compare them to other popular protein bars on the market. This table shows the typical sugar and sweetener profiles of several common bar brands.


Feature	Think! High Protein Bar	Think! Keto Delight Bar	RXBAR	Quest Bar
Total Sugars	0g (in many flavors)	1g - 2g	Varies by flavor (e.g., 12-16g)	1g
Sweeteners Used	Maltitol, Stevia, natural flavors	Erythritol, Stevia, natural flavors	Dates, fruit	Erythritol, Sucralose
Sugar Alcohols	High amounts (e.g., 8-12g)	Moderate amounts (e.g., 4-8g)	0g	High amounts (e.g., >8g)
Net Carbs	Higher due to sugar alcohols	Very low (3-4g)	Moderate to high	Low

Why Sugar Alcohols Matter

The presence of sugar alcohols like maltitol is a key differentiator for many Think bars, especially the 0g sugar varieties. For individuals sensitive to sugar alcohols, consuming these bars can lead to digestive discomfort. Additionally, while they have a lower glycemic index than regular sugar, they still impact blood sugar levels and should be accounted for, particularly for those with diabetes or strict carbohydrate monitoring needs. The labeling is important; while it accurately states '0g sugar,' it is not 'sugar-free' in the sense of containing no sweetening agents that affect carbohydrate intake.

Conclusion: Choosing the Right Think Bar for Your Needs

In summary, the sugar content of a Think bar is not a simple, universal number. While many of the brand's popular High Protein bars contain 0 grams of sugar, this is achieved through the use of sugar alcohols. For those monitoring sugar intake, it is vital to review the nutrition label of the specific product. The keto-friendly Delight bars offer a different profile with very low net carbs, while other lines also contain unique nutritional facts. Consumers should be mindful of sugar alcohols, their potential digestive effects, and their impact on blood sugar. By understanding these nuances, you can make an informed decision and choose the Think bar that best aligns with your dietary and health goals.
