Vitamin C is in charge of maintaining the structure of tendons
 It is a popular belief that Vitamin C must be ingested, especially when suffering a cold or flu. But the truth is that this vitamin has plenty of beneficial effects for the body. One of these is related to our joints’ health.
Vitamin C is important in the formation of collagen, a protein that nurtures, reinforces and keeps united our body’s tissues. Therefore, we can affirm that it is in charge of maintaining the structure of tendons, ligaments, cartilage, bone and teeth. Tendons are mostly formed by type I collagen, an element that gives rigidity and resistance to traction when it is subjected to stress, and flexibility when it is bent, compressed, or twisted. Therefore, the fact of incorporating vitamin C into our daily diet stimulates the synthesization of collagen in our tendons, so that it keeps its biomechanical properties. Additionally, vitamin C favours iron absorption, a mineral necessary for the growth and repair of tissues that, coupled with oxygen, also form collagen. If this was not enough, this well-known vitamin has great antioxidant power as it partly blocks the damage caused by free radicals, thus becoming the main ally of the sportsperson subjected to a high degree of physical wear.
