NAC (n-acetyl-cysteine) precursor to antioxidants that remove toxins

Is a precursor to glutathione, an amino acid manufactured in the body that is a powerful antioxidant and free radical scavenger. It helps the body to neutralize toxins, especially in the liver and lymphatic system. Clears congestion from the lungs and bronchial passages.*

A Word about Quality

Most dietary supplement manufacturers purchase n-acetylcysteine from Chinese sources. Medicinal Nutraceutics purchases amino acids only from Ajinomoto of Japan the world's recognized leader in the science and manufacturer of amino acids. 95% of all NAC comes from China and is processed from either human hair or duck feathers. Our NAC is produced through enzymatic reaction with organic materials. We pay at least 33% more for this superior grade n-acetylcysteine than we would the more common material from China.

Condition-Specific Nutritional Uses for N-Acetyl-cysteine

There are many clinical applications for n-acetylcysteine. Many physicians use n-acetylcysteine to treat acetaminophen (Tylenol) liver damage with great success*. It is also known as an antidote to mercury poisoning*.

A high level of homocysteine, a naturally occurring amino acid found in the blood, becomes problematic when in excess. Too much of it is related to a higher risk of coronary heart disease, stroke and peripheral vascular disease (fatty deposits in peripheral arteries). Other evidence suggests that homocysteine may promote atherosclerosis (fatty deposits in blood vessels) by damaging the inner lining of arteries and promoting blood clots. A study at Wallenberg Laboratory, Sahlgren's Hospital, S-413 45, Göteborg, Sweden showed that N-acetylcysteine reduced the levels of homocysteine by up to 45%.

Oral acetylcysteine is used for the prevention of radiocontrast-induced nephropathy (a form of acute renal failure)*. Some studies show that prior administration of acetylcysteine markedly decreases (90%) radiocontrast nephropathy¹*., whereas others appear to cast doubt on its efficacy ^{2, 3}*.. Worth considering is the newest data published in two papers in the New England Journal of Medicine and the Journal of the American Medical Association. The authors’ conclusions in those papers were:

1. “Intravenous and oral N-acetylcysteine may prevent contrast-medium–induced nephropathy with a dose-dependent effect in patients treated with primary angioplasty and may improve hospital outcome ⁴”
.
2. Acetylcysteine protects patients with moderate chronic renal insufficiency from contrast-induced deterioration in renal function after coronary angiographic procedures, with minimal adverse effects and at a low cost ⁵”.

Contraindications, Interactions and Side-Effects for N-acetylcysteine (NAC)

Side effects from n-acetylcysteine (NAC) supplements are rare when the recommended amount is under 1500 mg per day. However, high doses can cause gastrointestinal disturbances, nausea and vomiting.
