Which vitamins are needed for claw growth?

• A. Biotin, Vitamin E
• B. Vitamin C, Vitamin A
• C. Biotin, Vitamin D
• D. Vitamin K, Vitamin D

Answer: (A)

Claw growth relies on healthy keratin production and good skin integrity around the claw. Biotin (a B vitamin) is essential for keratin synthesis and fatty acid metabolism, which supports strong, healthy claws. Vitamin E acts as an antioxidant that protects skin and nail cells from oxidative damage and helps maintain moisture and flexibility—both important for ongoing claw growth. The other vitamins listed tend to influence collagen formation, skin health, bone metabolism, or clotting more than keratin-based claw growth, so they’re less directly involved. This combination—biotin for keratin production and vitamin E for skin protection—best supports claw growth.
