Currently, no medical evidence supports marketing claims that collagen supplements or drinks can improve hair growth, shine, volume, and thickness. There haven't been any studies in humans examining the benefits of collagen supplementation for hair. However, this small study had no control group taking a placebo to compare with the group receiving collagen supplements. One small 2017 study of 25 people with brittle nails found that taking 2.5 grams of collagen daily for 24 weeks improved brittleness and nail growth. Hardly any evidence supports the use of collagen to enhance hair and nails. But large, high-quality studies are needed to learn whether commercially available products are helpful and safe to use long-term.

A few randomized, controlled trials (see here and here) show that drinking collagen supplements with high amounts of the peptides prolylhydroxyproline and hydroxyprolylglycine can improve skin moisture, elasticity, wrinkles, and roughness.Most of the trials used commercially available supplements that contained more than collagen: vitamins, minerals, antioxidants, coenzyme Q 10, hyaluronic acid, and chondroitin sulfate were among the additional ingredients. That sounds promising, but it's unclear if these skin improvements were actually due to collagen. Those who used collagen supplements saw an improvement in the firmness, suppleness, and moisture content of the skin, with wrinkles appearing less noticeable.
A review and analysis of 19 studies, published in the International Journal of Dermatology, that had a total of 1,125 participants.What does the science say about collagen drinks and supplements? Typically, they contain peptides, short chains of amino acids that help make up essential proteins in the body, including collagen itself and keratin. But aging, sun damage, smoking, and alcohol consumption all decrease collagen production.Ĭollagen drinks and supplements often contain collagen from many different sources, such as fish, cattle, pigs, or chicken. Our bodies naturally produce collagen using the amino acids from protein-rich or collagen-rich foods like bone broth, meat, and fish. It also helps make up proteins such as keratin that form skin, hair, and nails. Collagen works with other substances, such as hyaluronic acid and elastin, to maintain skin elasticity, volume, and moisture. It's found in skin, hair, nails, tendons, cartilage, and bones. But what does the science say? What is collagen?Ĭollagen is a major structural protein in our tissues.
Since the collagen in our bodies provides crucial support for these tissues, it seems plausible that consuming collagen might lead to lush locks and a youthful glow. A tremendous buzz surrounds collagen drinks and supplements, as celebrities and influencers tout miraculous benefits for skin, hair, and nails.
