NOW Foods NAC N-Acetyl Cysteine - 600mg - 100 Vege Caps

N-Acetyl Cysteine (NAC) is the pre-acetylised form of cysteine, a non-essential amino acid (building blocks of protein). As a nutritional supplement, N-Acetyl Cysteine is powerful antioxidant, anti-toxin, and immune support compound. It is a precursor to glutathione, a substance that protects cells from oxidative damage. Molybdenum and Selenium are added to facilitate production of vital enzymes.

N-Acetyl Cysteine is a powerful antioxidant, superior anti-toxin, and high potency immune support compound. Antioxidants are beneficial substances that protect the DNA and cells from free radical attack. Free radicals is the primary cause of all the health concerns of ageing involving the cardiovascular system, nervous system, eyes, and skin. N-Acetyl Cysteine benefits the liver in its detoxification process, specifically getting rid of toxins from prescription medications, smoking, and alcoholism. As a precursor to glutathione, N-Acetyl Cysteine helps ensure that there is sufficient amount of glutathione in major organs that need it like the kidneys and liver. Glutathione depletion has been linked to failure of these vital organs. As part of its antitoxin effects, N-Acetyl Cysteine also protects the bronchi and the lungs from the harmful effects of smoking. The immune support action of NAC N-Acetyl Cysteine is also due to its ability to promote healthy glutathione levels. A healthy immune system means stronger defences against invading microorganisms and toxins that may cause diseases.

NAC N-Acetyl Cysteine is the simpler and more bioavailable form of the non-essential amino acid Cysteine. It produces very beneficial antioxidant, immune stimulating, and antitoxin effects. NAC is also the safer alternative for cysteine as pure cysteine in high dosages cause neurotoxic effects. This cysteine derivative contains sulfur that works by stabilising the formation of different protein structures needed by the body. It is also plays a very important role in the synthesis of glutathione, one of the primary antioxidants in the body. Glutathione is formed from the combination of cysteine and glutamic acid, plus glycine. N-Acetyl Cysteine supplements help maintain intracellular levels of glutathione. The liver and the kidneys are the major organs in which glutathione synthesis takes place, and are also the organs that need it the most. This premier antioxidant is helps the liver and kidneys in the body’s natural detoxification processes. With this, it assists in eliminating toxins which are potentially harmful to health. These toxins usually come from prescription medications for pain relief, antibiotics, and contraceptive pills, and also from processed foods, alcoholism, smoking, and environmental pollution. The production of glutathione also stimulates the body’s natural free-radical scavenging activities. N-Acetyl Cysteine protects serum lipids, nerve cells, eyes, and the skin from damaging free radical attack. Free radicals are the major cause of cell oxidation leading to cell death and then, tissue damage. Over time, tissue damage can become extensive in the cardiovascular system, eyes, skin, and the nervous system and then produces the harmful effects of ageing. NOW Foods NAC N-Acetyl Cysteine strengthens the immune stimulating, antitoxin, and antioxidant activities with Molybdenum and Selenium. Molybdenum and Selenium are trace minerals needed in the synthesis of different enzymes needed to maintain well being.
