NOTE: This is in a pure white powder form. Perfect for adding to your health drinks and smoothies. This is NOT in a capsule.
NOTE: This is 50 grams (50,000 mgs) of pure N-Acetyl L-Cysteine powder. Based on the recommend dosage of 600mg/day this is a 83 day supply! 600mg is one level 1/4 teaspoon. Very easy to measure out if you have measuring spoons.
N-Acetyl-L-Cysteine, or NAC, is an amino acid that acts as an antioxidant and is a precursor in the body to glutathione (GSH), a critical antioxidant. NAC is a more stable form of the amino acid cysteine (which is very unstable and oxidizes readily) because it has an acetyl group (CH3CO) attached. NAC is also more bioavailable and 6 times as cost-effective as the tripeptide glutathione. Glutathione consists of three amino acids: cysteine, glutamic acid and glycine. The body breaks this tripeptide apart before absorption, but the rate limiting (most valuable) amino acid for the purpose of making glutathione is the cysteine. Therefore, simply taking NAC makes much more sense.
Mechanism of action
Most of the beneficial effects of orally administered NAC are theorized to be a result of increased source of GSH groups. NAC can stimulate GSH synthesis, enhance glutathione-s-transferase activity, promote detoxification and act as an antioxidant.
