Vitamin C (Ascorbic Acid)
Vitamin C prevents the free radical damage that contributes to aging and cancer and cardiovascular disorders. It also plays a role in preventing other antioxidants, including vitamin A and E, from being oxidized, thus keeping them potent.

Vitamin C helps increase resistance to a range of diseases by stimulating production of lymphocytes and being available for the thymus

 gland. Thus it is used to reduce symptoms of Asthma and allergies.

Vitamin C increases the ability to handle physical and mental stress by being available to the adrenal glands in order to synthesize hormones.

It also enhances chemotherapy in addition to boosting immunity. Nitrosamines are proven carcinogens in animals and humans. Vitamin C blocks the process by which the body uses nitrites and nitrates to make nitrosamines and therefore block the formation of tumors.

Vitamin C help prevent high blood pressure and atherosclerosis by moving cholesterol from arteries to liver, where it’s converted to bile acids and then eliminated from the body. It reduces oxidation of LDL (bad cholesterol). It also prevents the deposition of lipoprotein (another fatty substance) in the vascular wall.

Vitamin C and E combined reduce the risk of vision loss by 10%.

In general vitamin C is essential for the growth and repair for tissues in all parts of the body. It is needed for the formation of collagen, connective tissue, and the formation of bones and cartilages. It helps other nutrient do their job, like its need to convert folic acid into its active form. It increases our ability to absorb iron and improves the bioavailability of selenium.
