The Claim

Pea protein supplementation at 20–22.5 grams per day for 84 days is associated with no significant difference in gastrointestinal tolerability or product likability compared to whey protein in sedentary adults, despite differences in amino acid composition and digestibility profiles.

In plain English

In sedentary adults, consuming 20–22.5 grams of pea protein daily for 84 days results in the same level of gastrointestinal tolerability and product likability as consuming the same amount of whey protein, even though the two proteins differ in amino acid content and how easily they are digested.

Pea protein supplementation at 20–22.5 grams per day for 84 days is associated with no significant difference in gastrointestinal tolerability or product likability compared to whey protein in sedentary adults, despite differences in amino acid composition and digestibility profiles.

Why this might work

When people consume pea protein or whey protein, both are broken down completely in the gut, releasing amino acids at similar rates. The taste and texture of both proteins are adjusted in the supplement form to be equally pleasant, so the body does not react differently to either one. This means the stomach feels the same, and people like the taste just as much, even though the proteins come from different sources.

  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 for three months said it was just as easy on their stomach and just as tasty as whey protein, even though the two proteins are different. The study confirmed this directly by asking participants.
