Clean, Reliable, and Does What It’s Supposed To
This is one of those supplements that just works quietly in the background. Thorne’s NAC is high quality, easy to swallow, and gentle on the stomach—no weird aftertaste or issues. I like knowing I’m getting a clean, well-sourced product from a brand I trust. It’s not flashy, but it’s effective, and sometimes that’s exactly what you want. Solid choice if you’re looking for a dependable NAC you can feel good about taking.

Worked for me!
I really saw the difference after about 3 months of use and with a combination of other supplements. Great brand and product.

Caused some hair loss/reduced back pain
**UPDATE** since stopping taking NAC, my back pain has returned. Turns out, NAC reduces back pain. I will be going back on it. ** **UPDATE** My issues had nothing to do with the brand, Thorne, only the NAC itself. Thorne is an awesome brand and I use many of their other supplements - Basic B complex, Berberine and another I can't think of at the moment. ** I didn't notice any better breathing. The one thing I did notice was hair loss. As soon as I started taking this, my hair started coming out like crazy. I didn't think about it being caused by this, even though it started about 2 days after starting NAC, but read a review on Reddit last night where someone else said they noticed hair loss when taking this. I have stopped it as of today.

Love it
I’ve been using Thorne’s NAC supplement for the past month, and I’m very pleased with the results. I started taking NAC primarily for its antioxidant and liver support benefits, and I can honestly say I feel a noticeable difference in my overall energy levels and respiratory clarity. Thorne’s reputation for clean, well-formulated products is what drew me to this version—and it didn’t disappoint. The capsules are easy to swallow, contain no unnecessary fillers, and I appreciate the transparency in their ingredient sourcing. This has become a staple in my supplement routine. If you’re looking for a reliable NAC supplement to support detoxification, immune function, or general wellness, I highly recommend giving Thorne a try
