Ingredients

Active ingredients per serve (as stated by the manufacturer): N-Acetyl-Cysteine (NAC)

Directions for use

Serving suggestion: As a dietary supplement for general health, take 1000mg with your favourite beverage between meals. Tips: If you use NAC for more than a month, add a mixed amino acid complex to your treatment regimen to ensure that you are getting adequate, balanced amounts of all the amino acids. NAC is most effective when taken on an empty stomach with a small amount of vitamin C powder. Vitamin C enhances the conversion of NAC to glutathione. If you've added a mixed amino acid complex to your NAC regimen, be sure to take it on an empty stomach as well, but at a different time of the day than you take the NAC. As the acetyl portion of the amino acid is quite irritating to the teeth, taking it through a straw is advised, and it also makes it more palatable.

Storage

Store below 25°C in a cool, dry place, away from direct sunlight. Some supplements (probiotics, certain fish oils) have specific storage requirements — check the on-pack labelling. Keep out of reach of children. Do not use after the expiry date printed on the pack.
