Pea Protein Isolate (Pisum sativum)

Pea protein isolate is a powder obtained by extracting and concentrating proteins from yellow peas (Pisum sativum), a legume grown primarily in Europe and North America. This process yields a particularly high protein content, generally above 80%, while minimising residual fats and carbohydrates. From a nutritional standpoint, pea protein isolate offers a complete amino acid profile and is notably rich in branched-chain amino acids (BCAAs) — leucine, isoleucine and valine — which contribute to muscle protein metabolism. It is also a valuable source of lysine, an amino acid that is often limited in plant-based proteins. Pea protein isolate supplementation is a suitable option for individuals looking to meet increased protein requirements, particularly in a sporting context or during dietary rebalancing. Its plant-based origin makes it a relevant alternative to animal proteins, suitable for vegetarian and vegan diets. Its digestibility, while slightly lower than that of whey, remains satisfactory and is well tolerated by most individuals.
