Why Take Antioxidants... ?

In recent years, much publicity has gone to the potential power of antioxidants - and for good reason. These vitamins and minerals bond with oxidants, preventing them from doing damage to the trillions of cells that make up the human body. Oxidants, free moving molecules that are created as byproducts of every process are body performs, such as eating, moving and even breathing, ricochet through a person's bloodstream; when they hit a cell, they cause damage to that cell's DNA. This damage leads to premature cell death, wrinkles (in skin cells) and even cancer. One of the most promising ways to prevent aging and prolong health is by preventing oxidants from doing damage.

N-Acetyl Cysteine (NAC) is a metabolite of the sulfur-containing amino acid, Cysteine. Cysteine is found in high protein foods, N-Acetyl Cysteine is not. N-Acetyl Cysteine is produced within the human body. Cysteine plays a role in the sulfation cycle, acting as a sulfur donor in phase II detoxification and as a methyl donor in the conversion of homocysteine to methionine. Cysteine also helps synthesize glutathione, one of the body's most important natural antioxidants and detoxifiers. N-Acetyl-Cysteine is the acetylated form of L-Cysteine.

Heavy metals like lead, mercury, and arsenic are detoxified and removed from the body by N-Acetyl Cysteine . It also increases the excretion of zinc and other essential minerals when taken over an extended period. It is therefore necessary to supplement zinc, copper and other trace minerals when taking N-Acetyl Cysteine.

Glutathione is known to aid in the transport of nutrients to lymphocytes and phagocytes, two major classes of immune cells, and to protect cell membranes. While purified glutathione is available as a dietary supplement, absorption is low, and N-Acetyl Cysteine is thought to be a better method of boosting cellular glutathione levels. N-Acetyl Cysteine is being investigated as a treatment for AIDS & Bipolar Depression

N-Acetyl Cysteine cleaves disulfide bonds by converting them to two sulfhydryl groups. This action results in the breakup of mucoproteins in lung mucus, reducing their chain lengths and thinning the mucus, improving conditions such as bronchitis and flu. Double-blind research has found that N-Acetyl Cysteine supplements improved symptoms and prevented recurrences in people with chronic bronchitis. N-Acetyl Cysteine at a dosage of 1,200 mg per day helps to prevent Influenza infection and reduce the symptoms and duration of existing Influenza infection.

N-Acetyl CysteineN-Acetyl Cysteine has been shown to reduce the proliferation of certain cells lining the colon and may reduce the risk of colon cancer in people with recurrent polyps in the colon. Its action as an antioxidant and a glutathione precursor may also contribute to a protective effect against cancer.

When taking N-acetyl cysteine it is recommended that two to three times as much Vitamin C be taken at the same time. Failure to do so may result in more harm than good from taking this product because of the prolonged presence of the oxidized form of L-Cysteine. Vitamin C also helps keep the glutathione that is produced from the Cysteine in its reduced form so that it can continue acting as an antioxidant.
