Vitamin C is required in the synthesis of collagen in connective tissue, neurotransmitters, steroid hormones, carnitine, conversion of cholesterol to bile acids and enhances iron bioavailability. Ascorbic acid is a great antioxidant and helps protect the body against pollutants. Because vitamin C is a biological reducing agent, it is also linked to prevention of degenerative diseases - such as cataracts, certain cancers and cardiovascular diseases.
Ascorbic acid also promotes healthy cell development, proper calcium absorption, normal tissue growth and repair, such as healing of wounds and burns. It assists in the prevention of blood clotting and bruising, and strengthening the walls of the capillaries.
Vitamin C is needed for healthy gums, to help protect against infection and assisting with clearing up infections and is thought to enhance the immune system and help reduce cholesterol levels, high blood pressure and prevents arteriosclerosis. Vitamin C can kill the antibiotic resistant tuberculosis bacteria.
Vitamin C is required to change proline into hydroxyproline (collagen) and lysine into hydroxylysine (collagen) which both help to repair tissue damage. It works best when accompanied by foods rich in rutin and hesperidin.
Nickel and vitamin C share a common antagonist; vitamin E. This inhibiting effect of vitamin E is not related to the antioxidative properties of vitamin C or vice versa (both are antioxidants, so in that respect they are synergistic), but they are antagonists ratio wise to one another, and to other chemical members: For instance, vitamin C increases iron uptake, which vitamin E inhibits. Vitamin C lowers manganese and zinc, while vitamin E helps increase manganese and zinc absorption. As a result, a very high intake of vitamin C will require an equally high intake of
vitamin E to maintain the same ratio.
Foods that contain high amounts of vitamin C help the lungs effectively transport oxygen throughout the body and improve lung function protecting against respiratory disorders and lung cancer. They can also effectively dissolve bladder and kidney stones.
