Solein is 65-70 % protein, 5-8 % fat, 10-15 % dietary fibres and 3-5 % mineral nutrients. The macronutrient composition of the cells is very similar to that of dried soy or algae. Solein solves many deficiencies: it provides a source of iron, fibre, B vitamins, and vitamin A in the form of beta-carotene, which also gives Solein its distinct colour.
While protein is found in both plant and animal-based foods, edible proteins are not all the same. They are made up of different combinations of amino acids and are characterised by the ratio of essential amino acids they have.
Solein contains all of the nine essential amino acids that are required by the human body.
