Vitamins and why we need them
Vitamin C RDA 60mg.
Vitamin C, also known as ascorbic acid, is a water-soluble vitamin. Unlike most mammals, we cannot make our own, therefore we must obtain this vitamin through our diet.
It is required for the synthesis of collagen, an important structural component of blood vessels, tendons, ligaments and bone. Vitamin C also plays an important role in the synthesis of the neurotransmitter norepinephrine. Neurotransmitters are critical to brain function and are known to affect mood. In addition, vitamin C is required for the synthesis of carnitine, a small molecule that is essential for the transport of fat to the mitochondria for energy use.
This vitamin is also a highly effective antioxidant. Even in small amounts vitamin C can protect molecules from damage by free radicals in the body such as proteins, lipids, carbohydrates, and nucleic acids (DNA and RNA). Vitamin C can regenerate other antioxidants such as vitamin E.
Vitamin C is needed to make collagen, the glue that strengthens many parts of the body such as muscles and blood vessels.
It plays an important role in wound healing and as a natural antihistamine. It also aids in the formation of liver bile and helps to fight viruses and to detoxify alcohol and other substances.
Researchers have shown that vitamin C improves nitric oxide activity. Nitric oxide is needed for the dilation of blood vessels, regulating activities of the brain, lungs, liver, kidneys, stomach, gut, genitals and other organs. Nitric oxide is also needed for erectile function in the male and is potentially important in lowering blood pressure and preventing spasms of arteries in the heart that might otherwise lead to heart attacks.
Note that ascorbic acid (synthetic vitamin C) in high doses can deplete blood copper, inhibit tyrosine metabolism (dopamine blocker), lower zinc levels and interfere with certain neurotransmitter manufacture.Symptoms associated with vitamin C deficiency
