Collagen supplements may improve nail growth and reduce brittleness
Collagen is a structural protein found in skin, hair, nails, tendons, cartilage, and bones. It is produced naturally in the body using the amino acids from protein-rich or collagen-rich foods like bone broth, meat, and fish. However, factors like ageing, sun damage, smoking, and alcohol consumption decrease collagen production.
Collagen supplements are often made from collagen-rich animal tissues, like the skin and bones of cattle and pigs, as well as fish scales and skin. The proteins are first denatured to form gelatin and then broken down into smaller fragments to be incorporated into powders, gummies, capsules, and protein bars.
While there is limited evidence of the benefits of collagen supplements for hair and nails, some studies suggest that they may improve nail growth and reduce brittleness. For example, a 2017 study by Hexsel et al. found that specific bioactive collagen peptides helped improve nail growth and reduced brittleness. Another clinical trial by Yagoda and Gans in 2012 showed that a supplement containing peptides, lipids, collagen, and hyaluronic acid led to a significant improvement in nail cracking, brittleness, and softness after eight weeks.
Additionally, a small 2017 study of 25 people with brittle nails found that taking 2.5 grams of collagen daily for 24 weeks improved nail growth and brittleness. However, this study did not have a control group, so it is unclear whether the improvement was due to the supplements or other factors. Similarly, a single-center trial with 25 participants conducted by Verisol® in 2017 found that specific bioactive collagen peptides increased nail growth rate by 12% and decreased broken nails by 42%. Nevertheless, larger, high-quality studies are needed to determine whether commercially available collagen products are effective and safe for long-term use.

Collagen is a major structural protein in our tissues
Our bodies naturally produce collagen using the amino acids from protein-rich or collagen-rich foods like bone broth, meat, and fish. However, aging, sun damage, smoking, and alcohol consumption all decrease collagen production. Collagen drinks and supplements often contain collagen from various sources, such as fish, cattle, pigs, or chicken. They typically contain peptides, short chains of amino acids that help make up essential proteins in the body, including collagen itself and keratin.
Some studies have found that collagen supplements may improve nail health. A 2017 study of 25 people with brittle nails found that taking 2.5 grams of collagen daily for 24 weeks improved nail growth and brittleness. Another study found that specific bioactive collagen peptides helped improve nail growth and reduced brittleness. In a clinical trial, a supplement containing peptides, lipids, collagen, and hyaluronic acid led to a significant improvement in nail cracking, brittleness, and softness after eight weeks.
However, it is important to note that the 2017 study had no control group, and there is limited evidence to support the use of collagen to enhance nail health. Extensive research has already demonstrated that sun protection and topical retinoids are effective in improving skin texture and elasticity and minimizing wrinkles. While collagen supplements may have some benefits, the evidence is not definitive, and marketing claims may be overstated.

Collagen works with hyaluronic acid to maintain skin elasticity
Collagen is a structural protein found in skin, hair, nails, tendons, cartilage, and bones. It works with hyaluronic acid and elastin to maintain skin elasticity, volume, and moisture. Collagen and hyaluronic acid are both fundamental building blocks of the skin.
Hyaluronic acid is a kind of carbohydrate, or sugar molecule, that can bind large amounts of water. It is produced naturally in the body and is found in the eyes, joints, and skin. It is key to skin moisture and helps to keep skin hydrated, flexible, and elastic. It also helps wounds heal faster and can reduce scarring.
Collagen, on the other hand, provides structural support for the skin. It is organized in a matrix, or scaffold, in the skin. This matrix provides shape and support. Collagen also helps make up proteins such as keratin, which form skin, hair, and nails.
Our bodies naturally produce collagen using the amino acids from protein-rich or collagen-rich foods like bone broth, meat, and fish. However, aging, sun damage, smoking, and alcohol consumption all decrease collagen production. This can lead to a decrease in skin elasticity, volume, and moisture.
Some people choose to take collagen supplements or drinks to boost their collagen intake. While there is some evidence that collagen can improve skin elasticity and moisture, there is limited evidence that it can enhance hair and nails.
Hyaluronic acid is also available in the form of serums, creams, lotions, ointments, and supplements. It is often used to treat dry skin and improve overall skin flexibility and elasticity.
Both collagen and hyaluronic acid can be used in injectable treatments to improve skin elasticity and volume.

Collagen is found in skin, hair, nails, tendons, cartilage, and bones
Collagen is a major structural protein found in several body parts, including skin, hair, nails, tendons, cartilage, and bones. It is also present in other bodily substances such as hyaluronic acid and elastin, which help maintain skin elasticity, volume, and moisture.
Collagen is composed of amino acids, which support the production of keratin, a protein found in skin, hair, and nails. Our bodies naturally produce collagen by breaking down protein-rich or collagen-rich foods like bone broth, meat, and fish. However, factors such as aging, sun damage, smoking, and alcohol consumption decrease collagen production over time.
Due to its presence in nails, tendons, and bones, collagen supplements have been marketed as a way to improve nail health and strength. Some small studies suggest that collagen supplements may have limited benefits for nail growth and brittleness. For example, a 2017 study of 25 people with brittle nails found that taking 2.5 grams of collagen daily for 24 weeks improved nail growth and reduced brittleness. Another clinical trial found that a supplement containing collagen, peptides, lipids, and hyaluronic acid led to significant improvements in nail cracking, brittleness, and softness after eight weeks.
However, it is important to note that the evidence supporting the use of collagen supplements for nail health is limited and not definitive. The 2017 study had no control group, making it challenging to determine if the supplements were solely responsible for the observed improvements. Additionally, no human studies have conclusively proven that orally ingested collagen will be deposited in the skin, hair, or nails. While collagen supplements may provide some benefits, focusing on sun protection and topical treatments has been shown to be more effective for skin health.

Collagen supplements may not support nail health
Collagen is a structural protein found in skin, hair, nails, tendons, cartilage, and bones. It is often marketed as a supplement to improve nail health, with claims that it can reduce brittleness and increase nail growth. However, the evidence supporting these claims is limited and inconclusive.
While some studies have shown promising results, they tend to be small-scale and lack control groups, making it difficult to determine causation. For example, a 2017 study of 25 people with brittle nails found that taking 2.5 grams of collagen daily for 24 weeks improved nail growth and reduced brittleness. However, the lack of a control group in this study limits the ability to attribute the improvements solely to collagen supplementation.
Additionally, the bioavailability of collagen supplements is a concern. When applied topically, collagen molecules are too large to penetrate the uppermost layer of the skin. Oral collagen supplements are believed to be more effective, but there is limited evidence to support this claim. No human studies have definitively proven that orally ingested collagen will reach the nails and have a therapeutic effect.
Furthermore, the role of collagen in nail health is not fully understood. While collagen is a component of hair follicles, it is not a primary constituent of nails, which are mostly composed of keratin. Collagen may support nail health indirectly by promoting keratin production, but the mechanism is not yet clear.
In conclusion, while collagen supplements may offer potential benefits for nail health, the current evidence is insufficient to confirm their effectiveness. More large-scale, well-controlled studies are needed to establish whether collagen supplements can truly support nail health and improve nail growth. In the meantime, individuals seeking to improve their nail health may consider other evidence-based approaches, such as protecting their hands from sun damage and maintaining a healthy diet rich in protein and nutrients.
