Pea Protein
High-quality, plant-based protein that supports muscle growth, satiety, and heart health.
Also known as: Pea Protein Isolate • Pea Protein Concentrate
Overview
Pea protein is a high-quality, easily digestible protein source derived from yellow split peas. It has become a popular alternative to animal-based proteins like whey and casein, especially among vegetarians, vegans, and individuals with allergies or sensitivities to dairy or soy. It is a complete protein, meaning it contains all nine essential amino acids, although it is slightly lower in methionine. To compensate, it is often combined with other plant proteins like rice protein. Rich in branched-chain amino acids (BCAAs) like leucine, isoleucine, and valine, pea protein is particularly effective for muscle building and repair. Studies have shown that pea protein supplementation, when combined with resistance training, can promote muscle thickness and strength gains comparable to whey protein. Beyond muscle synthesis, pea protein can also aid in weight management by promoting feelings of fullness and satiety. It is also considered a heart-healthy option, as it may help lower high blood pressure and cholesterol levels.
Key Benefits
