NAC (N-acetyl cysteine) is a supplement which the body converts into glutathione, an important antioxidant. Supplementation may be helpful for reducing symptoms of the flu and flare-ups of chronic bronchitis and COPD. NAC may also be beneficial in Sjogren's syndrome, renal failure, schizophrenia, compulsive behavior, and polycystic ovary disease.
We independently and rigorously tested the quality of many popular NAC supplements on the market. Among the products that passed testing, the cost to obtain an equivalent dose of NAC ranged from just 9 cents to 70 cents -- meaning that you can save a lot by shopping wisely. Some products contain added ingredients, but it may not be worth paying more for these. We also found that the daily suggested dose ranged just 500 mg to 1,800 mg, so it's critical that you know how much you really need rather than rely on labels.
You must be a member to get the full test results for NAC supplements along with ConsumerLab.com's recommendations and quality ratings. You'll get results for ten NAC supplements selected by ConsumerLab.com and for four others that passed the same testing through CL's voluntary certification program, as well as information about another product very similar to one of those that passed testing.
