Powdered vegetable protein drink flavored with goji and acai berry powder, quinoa flour and sweeteners. Unlike animal-based versions, plant-based foods are not complete sources of protein, meaning they don't contain all of the essential amino acids your body requires. However, with supplementation (with a combination of different vegetable protein sources) a protein complex of great value can be obtained. At Vegan Protein we achieve this by combining two protein sources that complement each other perfectly: rice protein that contains little lysine, but is rich in sulfur-containing amino acids (such as cysteine and methionine) and pea protein that contains less sulfur. . -containing amino acids while being rich in lysine. There are additional extras added to this excellent base.
