Nails themselves are made of keratin (say: KAIR-uh-tin). This is the same substance your body uses to create hair and the top layer of your skin. You had fingernails and toenails before you were even born.
Are nails alive?
Most of us do know that nails are made of a tough, dead substance called keratin, the same material that makes up hair. But nails actually start out as living cells. Behind the cuticles on fingers and toes, just beneath the skin, a structure called the "root" churns out living cells that go on to form the nail.
Are nails made of calcium?
Calcium is an important nutrient that plays a role in several bodily functions, including supporting nail and bone health. Some people may experience calcium deficiencies, which might cause dry, brittle nails. Calcium deficiencies result from insufficient calcium in the diet or the body not absorbing calcium properly.
