Our nails are made up of a protective protein called keratin, which is the building block of nails, hair and skin.

Nails respond best to the vitamins that encourage growth and production of keratin. Vitamin A is known for working at the cellular level, it promotes growth and differentiation of cells and tissues.

Vitamin B complex is yet another vitamin family that has a marked effect on the strength and health of nails. In this family, biotin or Vitamin H is especially recommended for healthy nails and hair.
