The Claim

Daily consumption of 10 billion CFU of a probiotic blend containing L. paracasei LP-DG® and L. paracasei LPC-S01 for two weeks significantly increases postprandial blood concentrations of methionine, histidine, valine, leucine, isoleucine, tyrosine, total branched-chain amino acids, and total essential amino acids following ingestion of 20 grams of pea protein in healthy young men, with increases ranging from 16% to 49% in maximum concentration and 16% to 27% in area under the curve.

What the research says

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
1 study reviewed
In plain English

In healthy young men, taking a specific probiotic supplement daily for two weeks increases the levels of several amino acids in the blood after eating 20 grams of pea protein, with measurable rises in peak concentration and total exposure over time.

See the scientific wording

In healthy young men, daily consumption of 10 billion CFU of a specific probiotic blend (L. paracasei LP-DG® and L. paracasei LPC-S01) for two weeks significantly increases postprandial blood concentrations of methionine, histidine, valine, leucine, isoleucine, tyrosine, total branched-chain amino acids (BCAAs), and total essential amino acids (EAAs) following ingestion of 20 grams of pea protein, with increases ranging from 16% to 49% in maximum concentration and 16% to 27% in area under the curve, suggesting a potential strategy to enhance amino acid availability from plant-based proteins.

Why this might work

Specific bacteria in the gut break down pea protein into smaller pieces and free amino acids before the body absorbs them, leading to more amino acids entering the bloodstream after eating pea protein.

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

    Taking this specific probiotic pill every day for two weeks helped the body absorb more important building-blocks from pea protein after eating it, making plant-based protein work better for muscles.
