The Claim

Supplementing with 20-22.5 grams of pea protein daily for 84 days, combined with a structured resistance training program of six 30-minute sessions per week, results in a 16.1% improvement in whole-body muscle strength and a 2.3% increase in muscle mass in healthy sedentary adults aged 30–59, with effects statistically comparable to those achieved with whey protein supplementation.

In plain English

In healthy sedentary adults aged 30–59, consuming 20–22.5 grams of pea protein daily for 84 days along with six 30-minute resistance training sessions per week leads to a 16.1% increase in whole-body muscle strength and a 2.3% increase in muscle mass, with results statistically similar to those from whey protein supplementation.

Why this might work

When someone eats pea protein, their body breaks it down into amino acids, especially leucine. This leucine signals muscle cells to start building more muscle proteins. When the person does strength training, the physical stress on the muscles makes this signal even stronger. Over time, the muscles grow bigger and stronger because they are making more protein than they are breaking down.

  1. Study: Efficacy of Pea Protein Supplementation in Combination with a Resistance Training Program on Muscle Performance in a Sedentary Adult Population: A Randomized, Comparator-Controlled, Parallel Clinical Trial

    People who took pea protein and did strength training six times a week for three months got significantly stronger and a little more muscular — just like those who took whey protein. The results were basically the same.
