Certain circumstances can affect the daily needs of these micronutrients. Factors such as age, stress, slimming diets or even sport, increase the need for vitamins and minerals.

Vitamin C: is found almost exclusively in fresh vegetables. It acts on the body as a carrier of oxygen and hydrogen, but also involved in the uptake of certain amino acids, folic acid and iron. Like vitamin E, have antioxidant effects. Being a water soluble vitamin just accumulates in the body, so a daily intake is important.
