What NAC is
N-acetyl-L-cysteine, usually shortened to NAC, is the amino acid L-cysteine with an acetyl group attached. Cysteine is one of the three amino acids your cells use to build glutathione, alongside glycine and glutamic acid. NAC is the form of cysteine you will find in most supplements.
The only medicinal ingredient is N-acetyl-L-cysteine, 1,000 mg per tablet. The rest is the tablet base: carbohydrate gum, dicalcium phosphate dihydrate, glycerin, hydroxypropylcellulose, magnesium stearate, microcrystalline cellulose, silica and stearic acid.
How it compares with Natural Factors' other NAC
Vitasave carries Natural Factors NAC at three strengths. The 1000 mg tablet is the one to pick if you want a full gram in a single daily dose:

The capsules suit people who prefer to adjust the amount by taking more or fewer. The 180-tablet bottle of NAC 1000 mg holds the same tablet as this one, at twice the count.
How to take it
Adults 18 and over take 1 tablet a day. Ask a health care practitioner first if you are pregnant or breastfeeding, or have kidney stones or cystinuria. Do not use it if you are taking antibiotics or nitroglycerin. The full directions and cautions are under How to Take.
Who it suits
Adults who want a high-strength NAC and would rather swallow one tablet than three or four capsules. A single 90-count bottle covers about three months, which keeps reordering simple.
