Wheat Peptides

Wheat peptides are wheat protein cut up by enzymes, sold as a supplement for blood pressure and as a hair and skin conditioner. The strongest evidence on file is for neither: a randomised placebo-controlled trial in 49 people with functional constipation reported about two extra spontaneous bowel movements a week against 0.4 on placebo, and a second double-blind study in 106 people paired wheat peptides with fucoidan against chronic superficial gastritis. The marketed uses have less behind them. The blood-pressure trial on file posted no results and was never published — the record names that as a gap — and no readable trial of them on skin exists.

Mechanism

Contain angiotensin-converting enzyme inhibitory sequences that slow angiotensin II formation and bradykinin breakdown.

Manufacturer’s claim vendor marketing

For a proprietary cosmetic ingredient the manufacturer is the originator — there is no upstream to defer to, and this is often the only description that exists. It is reproduced as an attributed claim, with the label its source gave it. It is not graded and it is not evidence — the graded studies are under Literature.

Vendor claims quoted from fetched page: "Gives an optimal level of conditioning and hair manageability"; "Increases by +20% the detangling effect on wet hair"; "Deeply smoothes dry hair"; "Can deliver the same level of performance than usual chemical conditioners". No n= or study duration given.

Dosing on file unverified

PEP5 peptide from fermented wheat peptone (clinical trial)

Carried from a source that labels it unverified, and reproduced with that label attached. A record of what is reported, not a recommendation. No citation on this page establishes it.

Notes unverified prose

Clinical trial: PEP5 treatment increased skin hydration and reduced fine wrinkles vs placebo (Biomater Sci. 2025 Jul 22); long-term RCTs scarce; CIR assessed safety not efficacy; Double-blind study: wheat peptides + fucoidan for gastritis; NCT02197910
