Life Extension N-Acetyl-L-Cysteine

N-acetylcysteine (NAC) is the non-essential amino acid cysteine with an acetyl group. The body uses L-cysteine for the production of the amino acids serine and methionine and the tripeptide glutathione. N-Acetyl-L-Cysteine is rapidly absorbed into the body. Life Extension provides GMO-free NAC.

Ingredients & Usage

Take one capsule 1-3 times daily with or without a meal, or as recommended by a health professional.

Please note:
People taking an N-acetylcysteine supplement should drink 6-8 glasses of water a day to prevent cysteine kidney stones. Cysteine kidney stones are rare, but do occur.

One container of Life Extension N-Acetyl-L-Cysteine contains 60 capsules, enough for 20-60 days.
