Blood is responsible for transporting substances around the body. Nails are largely made from the fibrous protein collagen. In order to make any protein the body needs the 'building blocks' of proteins - amino acids. These will be acquired from digested food, absorbed through the gut epithelium and transported to sites all over the body, where bodily cells construct the proteins needed.Why is a good blood supply important for healthy nail growth?
Good blood supply is essential for all growth and development and maintainance. Blood carries oxygen to organs and extremities (your hands, feet ). If oxgenated blood does not reach these areas, growth will cease and eventually areas that do not recieve it die.
