iHerb Customer Reviews

NAC is a very effective all-around antioxidant. It is particularly effective when it comes to liver and lung health. For smokers, or former smokers, or anyone suffering from bronchitis or lung disease, it will clean out your lungs amazingly well. Take on an empty stomach (I always take it with vitamin c) and one hour later you'll feel like a teenager again. As noted by another reviewer, the directions on the bottle are incorrect; NAC should always be taken on an empty stomach (with vitamin c)for maximum efficacy. This is not my favorite NAC, by the way. To me, the Life Extension brand works much better (alas, it cost more too!). Click my reviewer name to see how you can save up to $10 off your first order (free shipping too!). Iherb is the place I trust for all my health needs: low prices, huge selection, unbeatable service, and fast, free shipping. You can't go wrong!
