Soy protein is the most popular and best-known plant protein. It is obtained from defatted soy flour, purified from non-protein components. It is a complete protein because it contains each of the eight essential amino acids. It provides little fat, is free of gluten and lactose. Its biological value is comparable to the biological value of casein.

Most of the supporters of the supplements based on soy protein are women. In addition to a solid portion of protein, soybeans also provide phytoestrogens that promote the alleviation of menopausal symptoms, protect against loss of bone mass and have a positive effect on the cardiovascular system. Extensive research shows that men whose diet is properly balanced do not have to be afraid of soy protein and can boldly reach for the supplements that have this type of protein in their composition.

Preparations in this category are suitable for vegetarians and vegans. They can also be used by people struggling with lactose intolerance. Soy protein is easy to digest and does not cause stomach problems, which often occur after milk proteins. An additional advantage of this type of supplements is an excellent solubility and pleasant taste.
