Which processes in the body is vitamin C involved in, and why do people often choose it at certain times?

Vitamin C is one of the few micronutrients involved in several of the body's systems at the same time.

• Immune and nervous systems: ascorbic acid contributes to their normal function.
• Collagen formation: vitamin C helps the body synthesise collagen, a structural protein needed by the skin, gums, cartilage, bones and blood vessel walls. Without enough vitamin C, this process slows down.
• Energy metabolism: ascorbic acid contributes to energy-yielding metabolism, so it is often chosen during periods of increased tiredness or low energy.
• Antioxidant protection: vitamin C helps to protect cells from oxidative stress, that is, the effects of unstable molecules formed under stress, lack of sleep and environmental influences.

That is why vitamin C is often chosen during periods of heavy demands, changes of season or an unbalanced diet, when food does not fully cover the body's need for this nutrient.

Remember that a food supplement does not replace a varied diet and is not a means of treating or preventing diseases. If you take high doses of vitamin C over a long period, it is advisable to be guided by a specialist's opinion.
