Collagen function is to give strength to bones and structure to the skin.
Vitamin C is an essential part of a healthy diet and a good source of vitamin C are citrus fruits and green vegetables.
Vitamin C directs the synthesis of a structural protein called collagen.

Vitamin C stabilizes the collagen messenger RNA and increase the synthesis of collagen.
When there is a deficiency of vitamin C it leads to anemia, skin problems, gum diseases, and weakness.
