N-acetyl-L-Cysteine(NAC)


What is N-acetyl-L-cysteine ?

N Acetyl l cysteine (also spelled acetylcysteine, N Acetyl L Cysteine or N-acetylcyteine) is made from the amino acid cysteine joined to an acetyl group. Acetylcysteine (sometimes abbreviated as N-A-C or NAC) is a strong antioxidant. It donates the amino acid cysteine to help form the antioxidant glutathione. Glutathione is a powerful antioxidant normally found in the body. N-ACETYL L-CYSTEINE (NAC) or NAC is a more stable form of L-Cysteine because it has an acetyl group (CH3CO) attached. NAC has all the properties of L-Cysteine but is more water soluble and said to be more bioavailable than L-Cysteine.


What is the effective dosage of N-acetyl-L-cysteine supplementation?

The effective dosage of N-acetyl-L-cysteine is 500 mg per day.

What are the benefits of N-acetyl-L-cysteine supplementation?

• NAC is the most cost effective way to boost Glutathione (anti-oxidant) levels in the body. Glutathione is a very valuable peptide, but very expensive when bought as a supplement. It is best to use NAC to boost your glutathione levels.
• N-Acetyl-L-Cysteine, known as "NAC" provides powerful immune support and also packs a powerful anti-toxin potential. Its ability to neutralize cell and DNA damaging free radicals can help slow down what many scientists point to as a key factor in the aging process.
• NAC is a stable amino acid that can retain up to six times the amount of the sulfur and sulfhydryl groups after digestion.
• NAC has been shown to play a protective role against a variety of toxic hazards such as cigarette smoke, auto exhaust, certain herbicides, and overdoses of acetaminophen.
• NAC may also prevent toxicity to the kidneys during x-ray testing after injection with a contrast material in the bloodstream.
• A study funded by the National Institutes of Health (NIH) suggests that acetylcysteine can reduce the cravings associated with chronic cocaine use.
• It has very strong anti-oxidant property.
• It is used as a mucolytic agent to reduce the viscosity of mucous secretions. It has also been shown to have antiviral effects in patients with HIV due to inhibition of viral stimulation by reactive oxygen intermediates.


What are the side effects of N-acetyl-L-cysteine supplementation?

It appears to be safe at dosage below 500 mg/a day.
