1. A study revealed that supplementation with pea protein significantly contributed to increased biceps brachii muscle thickness after a 12-week resistance training program, particularly among participants who were less strong at the start of the study.

2. Studies found that pea protein supplementation was as effective as whey protein in promoting muscle thickness and strength, suggesting it can serve as a viable alternative to whey for those seeking plant-based options.

3. Pea protein was particularly beneficial for individuals starting or returning to resistance training, highlighting its role in enhancing muscle development during initial training phases.

4. Pea protein isolate tested in studies contain a high percentage of protein and essential branched-chain amino acids (BCAAs), which are important for stimulating muscle protein synthesis.
