Dr. MercolaNAC with Milk Thistle, 90 Servings (180 Capsules), 500 mg N-Acetyl-Cysteine Per Serving, Dietary Supplement, Supports Normal Detoxification Processes, Non-GMO

Great and trusted product. No upset stomach, easy to swallow, great value, quality ingredients, helps me sleep better and give me more energy.

So far so good. I use a lot of Tylenol and I read that this product detoxifies your liver when you take a lot of Tylenol.

I love this brand and won’t use any other brand.

This product works excellent and it's a miracle worker. The only product that worked when I was sick and helped me tremendously. I highly recommend this product for anyone and everyone. High quality product as well. Thank you!

It doesn’t matter what my opinion is because people still don’t believe it, they believe fake news and government.

works great

Great product.

Update: I did get a prompt response from company that they have always used duck feathers sourced from China and I should report packaging issues to Amazon. All other bottles of NAC that I have purchased (this brand and others) have smelled like sulfur. This one has almost no smell. Something is not right.Have been buying this for about two years. This bottle smells nothing like prior bottles (or any other NAC that I have purchased) and the packaging was different (all prior bottles came in a form fitted cardboard that was then in a cardboard box. This came wrapped in a piece of bubble wrap). NAC should smell like sulfur. This has almost zero smell. Tried to research if they changed the content and read that they are using duck feathers from China to create this. This wasn’t new but I was unaware. Fact that they smell nothing like prior is suspicious to me. $50 is a lot of money if you aren’t sure that you are getting what you paid for.
