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.
Functions in the Body
- Important for the immune system

- Forms collagen (protein building blocks) in the skin, tendons and ligaments
- Builds tissue, bones and teeth
- Helps in healing wounds

Not known. Vitamin C is harmless even in large amounts (up to 1 grams / day).
+ Vitamin E and beta-carotene promote the body’s vitamin C utilization, which optimizes iron absorption.
– Smoking increases the body’s vitamin C requirement to about 35 mg per day. Alcohol consumption, acetylsalicylic acid (aspirin), contraceptives (“the pill”), antidepressants or diuretic medications also adversely affect the body’s vitamin C levels.
Vitamin C is found mainly in vegetables and fruits: Black currants, peppers, green vegetables such as broccoli, citrus fruits, and also potatoes provide lots of vitamin C.
