    • Why Amazon no longer carries this item

      from Napa on 7/20/2021
      It is so ridiculous that I have to find another source beside Amazon to get this item. I am a biochemist and the reasons given are just stupid. I made a purchase of it through another company, had to pay shipping and by the time it arrived- I imagine by slow donkey to the Grand Canyon and then to California- a week and a half later- I was disgusted.

      Pros

      Its a helpful therapeutic and potent defense against hepatotoxins-

      Cons

      The fact that I can't get the 600 mg 250 capsules from Amazon for around $16.00 (shipping included and two day delivery).

      N Acetyl Cysteine (NAC)

      from Elyria on 7/30/2020
      I have been taking NAC as an antioxidant, immune boost and heavy metal detox. It was tested to help strengthened the bones when added to a vitamin D and calcium supplements. I have osteopenia so I try to support my bones any way that I can.

      Pros

      I like that it is high potency.

      Cons

      I prefer the veg capsules to the tablets
