Product Information
N-Acetyl-Cysteine (NAC) is the stable form of Cysteine, one of twenty amino acids involved in building proteins throughout the body.
We’ve taken every step to produce a high-quality NAC formula that offers exceptional value for money. Each small, easy-to-swallow capsule contains 600mg of pure N-Acetyl-Cysteine, a level consistent with studies. We’ve also provided NAC in its free form – which doesn’t require any digesting – to facilitate superior absorption.
NAC is one of the few amino acids that contains sulphur and its associated sulphuric smell. Although this smell is quite normal, we've chosen a capsule casing over a straight powder or tablet to reduce the incidence of any odour.
We manufacture and package our formula in UK factories working to strict Good Manufacturing Practice (GMP) to meet our rigorous quality standards.
This product is suitable for vegetarians and vegans.

"Good for respiratory Health"

I had been prescribed this in the EU whenever I had bronchial problems. It helps to fluidify the lungs and hence acts as a decongestant. Hence I have continued using it for bronchial problems since returning to the UK. Furthermore a Belgian doctor friend of mine has twins who suffer from c***** f*****is and he uses it in spray form to help reduce their symptoms.

I had been using NAC+ from a different manufacturer but purchased this as it was cheaper. A false economy! It is smelly and incredibly difficult to take giving me burning indigestion.
The capsules are way too large. The results poor/non-existent.

Thank you for taking the time to leave a review. I am sorry to hear about your experience with the NAC. We would expect it to have a smell, but not to give the symptoms you describe. I have contacted you separately about this matter.
