Hair, skin and nail vitamins are intended to keep these parts of the body healthy. Vitamins and minerals, such as calcium, biotin, zinc, and vitamins C, E, D and A, are believed to be crucial for supporting the health of skin, hair and nails. Hair, skin and nail vitamins can help keep the skin, nails and hair strong, supple and healthy, and they may also have other health benefits.
Vitamin deficiencies are believed to be most apparent from the condition of one's hair, skin and nails. Brittle, dry and dull skin, nails and hair can often indicate deficiencies of B vitamins, as well as vitamins A and D. Vitamin A is believed essential for normal hair and nail growth, and a deficiency in this vitamin may lead to more brittle nails and contribute to hangnails. Vitamin D can help to support the health of hair follicles, for strong hair growth, and can also help with the absorption of calcium for stronger hair, skin and nails. Biotin, a B vitamin complex, may help to support hair growth and prevent hair loss.
Antioxidant vitamins such as vitamins C and E can support skin health, removing free radicals from the body to prevent the damage caused by oxidation. This can help to slow the signs of aging and help maintain skin's youthful appearance. The zinc and calcium found in many hair, skin and nail vitamins can help prevent hair loss. Zinc and calcium in hair, skin and nail vitamins can also strengthen the nails, making them less brittle and less likely to break.
Omega-3 fatty acids form an essential ingredient of some hair, skin and nail vitamins. These fatty acids are said to help keep skin supple and well-moisturized. They can also support cognitive function and may have benefits for cardiovascular health.
The vitamins and minerals found in most hair, skin and nail vitamins are often the same vitamins necessary for overall good health. Calcium, for instance, helps support the health of teeth and bones.
