Vitamin C – Ascorbic Acid

Vitamin C is probably the best known vitamin. Unlike animals, human beings cannot produce vitamin C themselves. The water-soluble vitamin C is involved in numerous metabolic activities and active throughout the body. For example, it is a strong reducing agent, which means it captures free radicals, caused by smoking, stress, illness or poor nutrition. As a result, cells and tissues are protected and the immune system is strengthened.
Vitamin C is very sensitive to heat, light and oxygen. Vegetables and fruits should be eaten fresh, stored in the dark and processed as little as possible in order to minimize vitamin losses.
