Which vitamin is essential for healthy nail growth?

Biotin, also known as vitamin B7, plays a crucial role in maintaining healthy hair and nail growth. It is a water-soluble vitamin that contributes to the production of keratin, the protein that makes up the structure of nails and hair. Adequate biotin levels have been linked to improved nail strength and thickness, making it an essential nutrient for anyone looking to promote healthy nail growth.

While other vitamins, such as Vitamin C (important for collagen production), Vitamin D (which supports overall health including skin and bone health), and Vitamin A (essential for cellular repair and growth), also contribute to general health, biotin is specifically noted for its direct impact on the health and growth of nails. Therefore, it is the most relevant vitamin in this context.
