Calories in Gummy Worms: Nutrition Facts & Serving Sizes
Per 7 pieces (40g)
Per 100g
Source: Web research, March 2026.
Gummy worms contain 300 calories per 100g, all coming from carbohydrates and sugar. A standard 7-piece serving (40g) delivers 120 calories with 30g of carbs and 25g of sugar. Like all gummy candy, they have zero fat, zero fiber, and no micronutrients whatsoever. The 5g of protein per 100g is from gelatin, an incomplete protein that does not support muscle building. Gummy worms are pure fast-digesting sugar in a large, chewy format that makes it easy to eat more than one serving without realizing it. The 7-piece serving size is a useful reference point, but most people eat significantly more. At 62.5g of sugar per 100g, gummy worms are among the highest-sugar foods by weight. They belong in the occasional treat category for anyone with body composition goals, tracked carefully when included.

Health Benefits of Gummy Worms
Gummy worms provide no meaningful health benefits. They are composed almost entirely of sugar, corn syrup, and gelatin, with zero vitamins, minerals, or fiber. From a nutritional standpoint, they are empty calories.
The only context in which gummy worms might serve a purpose is as a fast-acting carbohydrate source for endurance athletes or during intense intra-workout nutrition. The complete absence of fat and fiber means sugars absorb rapidly into the bloodstream, which can be useful for sustained high-intensity efforts when glycogen stores need quick replenishment. Some endurance runners and cyclists use gummy candy in this way.
The gelatin component comes from hydrolyzed animal collagen, and there is some evidence that collagen peptides support joint health and recovery. However, the amounts present in a candy serving are far too small and the protein quality too poor to offer any benefit.
For anyone focused on body composition, weight loss, or building muscle, gummy worms deliver no nutritional return on their caloric cost. They are best consumed as an occasional indulgence with full awareness of the calorie and sugar content.
Dietary Considerations
Gummy worms are fat-free but extremely high in sugar (62.5g per 100g), making them incompatible with keto, low-carb, and diabetic-friendly diets. A single 7-piece serving contains 30g of carbs, which would exceed the daily carb limit for most ketogenic dieters. Standard gummy worms are not vegan because they contain gelatin from animal collagen. Pectin-based vegan alternatives are available. They are typically gluten-free, but labels should be checked since manufacturing facilities may process gluten-containing products. For weight loss, gummy worms are a poor choice due to the high sugar content, zero satiety value, and complete lack of micronutrients. They can fit into a flexible dieting approach if tracked accurately within your daily calorie budget.

Frequently Asked Questions
How many calories in gummy worms?
Gummy worms have 300 calories per 100g. A standard serving of 7 pieces (40g) contains 120 calories with 30g of carbs and 25g of sugar. Since gummy worms are easy to overeat, tracking serving size carefully is important.
Are gummy worms good for weight loss?
No, gummy worms are not good for weight loss. They are high in sugar, provide no fiber or protein to create fullness, and offer zero nutritional value. The rapid blood sugar spike from 25g of sugar per serving typically leads to a crash and increased hunger shortly after eating. They are best saved as an occasional treat during a cut, tracked accurately.
How much protein in gummy worms?
Gummy worms contain 5g of protein per 100g, or about 2g per 7-piece serving. This protein comes from gelatin, which is an incomplete protein missing key essential amino acids. It does not contribute meaningfully to muscle protein synthesis and should not be counted as a protein source.
Are gummy worms vegan?
Standard gummy worms are not vegan because they contain gelatin, which is made from animal bones and connective tissue. Vegan versions made with pectin or agar exist, but regular brands like Trolli and Haribo use gelatin. Always check the ingredient list if you are avoiding animal products.
How much sugar is in gummy worms?
Gummy worms contain 62.5g of sugar per 100g, one of the highest sugar concentrations of any food by weight. A standard 7-piece serving (40g) provides 25g of sugar. There is no fiber to slow absorption, so the sugar hits your bloodstream quickly.
How do gummy worms compare to gummy bears?
Gummy worms and gummy bears are nutritionally similar. Gummy bears have 333 calories and 46.7g of sugar per 100g, while gummy worms have 300 calories and 62.5g of sugar per 100g. Gummy worms are slightly lower in calories but higher in sugar percentage. Neither offers any meaningful nutritional value.
