I had one from other brand and runout. My acupuncturist told me Now is good brand and reasonable, affordable so I give it try. I could feel immediate change. I also tried wormwood tincture it also worked well.

I was advised by the doctor to start using this. He recommended NOW products. It's hard to say if these products are working until you use them for a while. I will keep taking it just the same.

NAC is a recommended vit/mineral that totes repair/maintenance of damaged lung tissue. I must say that I do appear to breath better when I was taking it verses the 2 weeks I was on vacation and decided not to lug a huge bottle of that with me. I will continue to buy it and will now take it where ever my vacations take me. 600mg/2xdaily

Fast shipping at a time where everything is taking longer than usual. Just as I ordered and happy to find a product that was back ordered elsewhere. 4 stars are due to paying 20% more than other places I have ordered in the past. I did choose to pay it as I was happy to find.

Good product works very good

Great purge tool.

Excellent quality supplement. Can't find anything near the quality for the price.
