Synopsis
Source of validity: Scientific
Rating (out of 5): 4
Protein plays a crucial role in supporting the health and growth of nails, as nails are primarily composed of a fibrous structural protein called keratin. Scientific studies have established that adequate dietary protein is essential for the synthesis of keratin and, consequently, for maintaining strong and healthy nails. Protein deficiency can lead to brittle, weak, or slow-growing nails, a phenomenon observed in individuals with malnutrition or certain restrictive diets. Clinical nutrition literature and dermatological research support the recommendation of sufficient protein intake to promote optimal nail growth and structure. While specific supplementation with “unspecified” protein (as opposed to targeted amino acids or hydrolyzed keratin) is less commonly studied, the general consensus is that adequate total protein intake is foundational for nail health. Various guidelines from health authorities and dermatology associations include protein among the nutrients necessary for healthy nail maintenance. However, there is limited evidence that consuming protein in excess of daily requirements will further enhance nail quality in healthy individuals who already meet their protein needs. Overall, the use of protein to support the nails is justified by a solid scientific understanding of nail biology and nutrition.
