Which vitamin is particularly important for healthy nails?

• A. Vitamin A
• B. Vitamin C
• C. Vitamin D
• D. Vitamin B7 (Biotin)

Answer: (D)

Vitamin B7, commonly known as biotin, is particularly important for healthy nails due to its role in keratin production, which is the primary protein that makes up the structure of nails. Biotin supports the health and strength of nails by promoting nail growth and preventing brittleness. Studies have shown that individuals with biotin deficiency may experience nail abnormalities such as thinning, splitting, or peeling.

Biotin contributes to the metabolic processes that convert food into energy, which is essential for the growth of cells in the nails. A sufficient intake of biotin can lead to stronger, healthier nails and help prevent common nail issues. This makes it a crucial nutrient for anyone looking to maintain or improve the condition of their nails.
