Question

Do collagen supplements really work?

Answer 1

If you're using them for healthy skin, nails and hair, it seems a waste of money.

Collagen comes from protein, the foods you eat. Collagen is a structural tissue and it is replaced very slowly. It is made of fibrous protein. In fact, collagen comprises 30 percent of the total body protein. A person who has been sick, or who has been on an extremely low-protein diet, very often sees the muscles in his or her arms and legs begin to sag, which is a sign that they have probably lost collagen.

So spend the money on good quality protein like lean meat, eggs,  etc.
