Study: What is the function of vitamin C in Natriche Immune Sport

Natriche Immune Sport contains vitamin C. Vitamin C or ascorbic acid is by far the best known vitamin. Already in the 16th century, sailors knew that citrus fruits and fresh vegetables could prevent scurvy. It was only much later that it became known that this disease was related to a serious vitamin C deficiency. Athletes also benefit greatly from taking a vitamin C supplement.

What is vitamin C?

Vitamin C, also known as ascorbic acid, is a water-soluble vitamin and is important for good resistance in the first place. In addition, it ensures healthy bones, teeth, blood vessels and skin. Vitamin C also ensures a well-functioning nervous system and contributes to energy supply. It is also an antioxidant and protects the body together with vitamin E against free radicals. Free radicals play a role in aging processes. Vitamin C also promotes the absorption of iron.

Humans cannot produce vitamin C themselves and are completely dependent on food for the vitamin C supply. Vitamin C is also not stored by the body so it is important that you get it every day. The most famous source of vitamin C is the orange. But vitamin C can be found in many more fruits and vegetables. For example, a paprika contains much more vitamin C than an orange. Vitamin C can also be found in kiwi, lemon, strawberries, berries, tomatoes, broccoli, Brussel sprouts, cauliflower and potatoes. It is important to know that vitamin C is water-soluble. With prolonged cooking of vegetables, the vitamin C content decreases. Even when exposed to air or high temperatures, some of the vitamin C in food is lost.

Health benefits of vitamin C:

  • Supporting the immune system during and after physical exercise


  • Prevents strained muscles and ensures better muscle recovery


  • Helps with the protection of cells against oxidative damage


  • Maintains strong bones and teeth


  • Helps with the absorption of iron


  • Reduces wrinkles and prevents skin aging

Why is vitamin C important for athletes?

After intensive training, your muscles are damaged and vitamin C plays an important role in connective tissue repair. Vitamin C is also an antioxidant. This means that it protects the body against harmful influences, such as smoking, stress and little rest.

Another important reason is the fact that vitamin C plays an important role in the formation of collagen. Blood vessels, cartilage, bones and tendons are made from collagen. To keep your blood vessels, cartilage, bones and tendons healthy, vitamin C is extremely important!

Because the body does not store vitamin C, it is important that you get it at different times every day. Nutritional supplements that contain vitamin C are therefore a nice addition to your daily diet, so that you know for sure that you get enough vitamin C.
