The Claim

In healthy young men, a 2-week supplementation of a specific probiotic blend with 20g pea protein increases plasma histidine concentrations by up to 49%.

In plain English

In healthy young men, taking a specific probiotic blend with 20 grams of pea protein for two weeks raises the level of histidine in the blood by up to 49%.

See the scientific wording

In healthy young men, a 2-week supplementation of a specific probiotic blend with 20g pea protein increases plasma histidine concentrations by up to 49%, suggesting a potential role in modulating amino acid metabolism or reducing microbial fermentation byproducts in the gut.

Why this might work

Specific bacteria in the gut break down pea protein into smaller pieces and free amino acids, allowing the intestine to absorb more histidine from the food, which then enters the bloodstream at higher levels.

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

    Scientists gave healthy young men a probiotic pill along with pea protein for two weeks and found their blood histidine levels jumped by nearly half—exactly what the claim said. This means the combo likely helps the body absorb more histidine from plant protein.
