Protein is made of chains of amino acids, out of which 9 is essential. They cannot be produced by the body hence we need to get them from food. While animal sources of protein including whey contain all 9 essential amino acids and thus are considered complete, plant-based protein sources only provide a few or have a lower percentage of at least one of the amino acids. That is why we combine pea protein which is low in the amino acids cysteine and methionine but rich in lysine with a second plant-based source, namely rice protein. Rice protein is low in lysine, but very high in cysteine and methionine. Thanks to this combination, we achieve a 100% vegan and complete essential amino acid profile.
