I use these to liquify mucous in my lungs - they seem to work.

Read that NAC has absorbtion problems. This formula is supposed to do better.

This product really works great! I have an immune system deficiency and I get lots of colds and flus, and this NAC has cut down on my sick time.

Outstanding NAC Formula

There is a lot of good science in this, particularly the sustained release. It really seems to work for me and I recommend it to anyone needing such a supplement.

I bought this to substitute GNC's NAC, of which I was taking 2/day (300mg each). 1/day of this works equally well, if not better, for energy, both physical and mental.

With allergy problems, I'm happy to find a sustained NAC in a good dosage.

Good for the lungs

Posted by Reviewer3058529 on May 19, 2011

I take this as a preventative for my lung condition (bronchiectasis). This particular brand offers a sustained release, which research appears to indicate is more beneficial and assimilable.

I'm sold. I feel so much better in the morning after taking one of these with or after dinner. Great product.
