Is Classic Vanilla marshmallows Keto?

The Ingredient Breakdown

As a food scientist, I look for the 'hidden carbs' that often derail a ketogenic diet. The first thing I noticed about this product is the complete absence of sugar. Instead, the sweetness comes from a combination of xylitol, monkfruit sweetener, and prebiotic inulin.

Xylitol and the erythritol in the monkfruit blend are sugar alcohols. The body does not metabolize them in the same way as regular sugar, resulting in a negligible impact on blood glucose levels. Prebiotic inulin (derived from chicory or artichoke) is a fibrous carbohydrate that acts as a sweetener and a gut-health booster without spiking insulin.

Perhaps the most impressive addition is MCT oil (Medium Chain Triglycerides). Standard marshmallows are pure sugar, but this version adds healthy fats. MCTs are rapidly absorbed and converted into ketones, actually fueling your ketosis state rather than breaking it. Finally, the structural integrity comes from grass-fed gelatin and collagen peptides, which provide protein and gut-supporting amino acids without any carb load.

Nutritional Value

When evaluating a product for keto, we look at the 'Net Carb' count (Total Carbs minus Fiber and Sugar Alcohols). For these marshmallows, the math is highly favorable. With roughly 15 calories per serving and 1g of total carbohydrates, the net carb count is effectively zero once you subtract the fiber and sugar alcohols.

The inclusion of MCT oil shifts the macro profile away from 'empty calories' toward a functional fat source. While they aren't a significant source of vitamins, they provide a 'treat' experience without the insulin spike associated with glucose-based sweets. They fit easily within the strictest daily carb limits (usually 20-50g) of a standard ketogenic diet.
