Vitamins & Minerals for Nail Health

Normal nail growth depends on overall nutrition, but taking extra vitamins does not guarantee stronger nails when intake is already adequate.

Biotin

Biotin is the best-known “nail vitamin,” though evidence for routine use is limited. Read the dedicated guide.

Iron and zinc

Deficiencies can affect many body systems, including tissues involved in nail growth. Testing and clinical context matter; appearance alone is not a reliable diagnosis.

Vitamin C and D

Both have important physiological roles, but product-specific nail claims require evidence beyond simply including these nutrients in a formula.

Before supplementing

Consider diet, symptoms, medications and whether a clinician has identified a deficiency. For product selection, continue to our nail supplement guide.
