Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Bovine (unspecified), often referring to bovine-derived collagen or gelatin, is used in dietary supplements aimed at supporting nail health. The rationale for its use is primarily based on the protein and collagen content, as nails are composed largely of keratin, a structural protein. Several scientific studies have investigated the impact of collagen supplementation on nail growth and strength. For example, a 2017 open-label trial (Hexsel et al., Journal of Cosmetic Dermatology) found that daily collagen peptide supplementation improved nail growth rate and reduced the frequency of broken nails in participants over 24 weeks compared to baseline. Other research suggests that collagen may increase nail thickness and decrease brittleness, although most studies are small, industry-funded, and sometimes lack placebo controls.

While the evidence is not overwhelmingly strong (hence a rating of 3), there is a moderate level of scientific support for the use of bovine-derived collagen supplements in promoting nail health. The mechanism is thought to involve collagen peptides providing amino acids that serve as building blocks for keratin and stimulating the body's own collagen production. However, it is important to note that not all bovine-derived products are equal; the benefit is mostly attributed to hydrolyzed collagen peptides rather than generic bovine tissue extracts. More rigorous, independent studies are needed to confirm these effects and determine optimal dosages and forms. Nonetheless, current evidence does suggest a potential benefit, placing the justification for use in the "scientific" category.
