About Rye (Secale cereale) Grain Extract
Rye grain/seed extract (Secale cereale) appears in a few hair-growth formulas (e.g. Vitabiotics Hairfollic) at ~6 mg/day, presumably as a source of lignans/phytosterols. There are no human trials of rye grain extract for hair, skin, or any other supplement indication; the only rye-related human data are for whole-grain rye foods (lipid/glucose crossover studies) and for rye pollen extract in prostate conditions — neither transfers to a 6 mg seed extract. Evidence is therefore insufficient and the ingredient should be regarded as label decoration. Contains gluten-related proteins in trace amounts (secalin) — coeliac patients should check the product's gluten status.

How much Rye (Secale cereale) Grain Extract to take
The RDA prevents deficiency. The effective range is what clinical trials used to actually move the outcome.
Effective
6–100
mg
No clinical dose exists. Hair-supplement labels use ~6 mg/day; the range here is a placeholder anchored to label practice, not to any trial. Do not confuse with rye POLLEN extract (Cernilton/Graminex, 189–378 mg/day for prostatitis/BPH), which is a different plant part with its own trials and is deliberately NOT matched by this entry.
Clinical evidence
Clinical evidence. No clinical trials of rye grain extract as a supplement; whole-grain rye and rye pollen data do not apply
