Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Methionine is an essential amino acid that plays a key role in a variety of biological processes, including the synthesis of proteins and the production of important molecules such as S-adenosylmethionine (SAMe), which is involved in methylation reactions. In the context of hair health, methionine is sometimes included in supplements with claims that it can support hair growth or strength. The rationale is that methionine contributes sulfur, which is an important element in keratin, the structural protein that makes up hair.

However, the direct scientific evidence supporting the use of methionine supplementation specifically for improving hair growth or health in individuals without a deficiency is limited. Most of the support comes from the understanding of its role in protein and keratin synthesis, not from clinical trials demonstrating a clear benefit in hair growth or quality. A few small studies and animal experiments have suggested a potential supportive effect, particularly when methionine is combined with other nutrients, but robust, large-scale human studies are lacking.

Overall, while the use of methionine for hair health is grounded in biochemical rationale and some preliminary evidence, it is not strongly supported by high-quality clinical trials. Thus, the evidence rating is 2 out of 5.
