Synopsis

Source of validity: Scientific
Rating (out of 5): 4

Pea and rice protein blends are increasingly used in the context of bodybuilding due to both their nutritional profile and scientific evidence supporting their efficacy in supporting muscle protein synthesis and recovery. Both pea and rice proteins are rich in essential amino acids, though each is incomplete by itself—pea protein is low in methionine, while rice protein is low in lysine. When combined, they provide a more complete amino acid profile, similar to animal-based proteins like whey.

Several studies have examined the effects of plant-based protein blends on muscle hypertrophy and strength gains. For example, a 2015 randomized controlled trial published in the Journal of the International Society of Sports Nutrition found that pea protein supplementation promoted a similar increase in muscle thickness as whey protein during resistance training. Additionally, rice protein has demonstrated comparable effects to whey protein in terms of muscle recovery and strength improvements. The digestibility and bioavailability of the blend are also high, making it suitable for athletes and bodybuilders seeking plant-based alternatives.

While the totality of evidence is not as large as for whey protein, the available studies and knowledge of amino acid requirements suggest that pea and rice protein blends are a scientifically valid option for supporting bodybuilding goals, particularly for individuals who avoid dairy or animal products.
