The base is potato starch, which gives kissel its characteristic body. Sweetness comes from added sugar, so this product is not suitable for low-sugar or ketogenic diets. Citric acid provides the tart berry note, and ascorbic acid (vitamin C) is included as a nutrient. The red-pink color comes from carmine (E120), a colorant derived from cochineal insects; people who avoid animal-derived additives or have rare carmine sensitivity should note this. The powder contains no milk, egg, soy, nuts, or gluten-containing cereals in its listed composition, but always check the physical label for cross-contamination statements if you have severe allergies. Because it is a carbohydrate-based drink, it contributes calories primarily from starch and sugar — treat it as a food item, not a supplement.
