The Claim

A specific probiotic blend consisting of L. paracasei LP-DG® and L. paracasei LPC-S01 increases plasma concentrations of branched-chain amino acids by 22–27% following pea protein ingestion in healthy young men, without altering absorption kinetics, thereby enhancing the anabolic signaling capacity of plant proteins.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect

In plain English

When healthy young men consume pea protein after taking a specific probiotic blend containing L. paracasei LP-DG® and L. paracasei LPC-S01, their blood levels of branched-chain amino acids rise by 22–27%, and this increases the activation of muscle-building signals from the protein without changing how quickly the protein is absorbed.

See the scientific wording

A specific probiotic blend (L. paracasei LP-DG® and L. paracasei LPC-S01) increases plasma concentrations of branched-chain amino acids (BCAAs) by 22–27% after pea protein ingestion in healthy young men, potentially enhancing the anabolic signaling capacity of plant proteins without altering absorption kinetics.

Why this might work

Specific bacteria in the gut break down pea protein into smaller pieces and free amino acids, allowing more branched-chain amino acids to enter the bloodstream without changing how fast they are absorbed.

  1. Study: Probiotic Administration Increases Amino Acid Absorption from Plant Protein: a Placebo-Controlled, Randomized, Double-Blind, Multicenter, Crossover Study

    This study found that taking a specific probiotic pill with pea protein made the blood levels of muscle-building amino acids go up by 22–27% — just like the claim says — without making them show up faster.
