Good product!

NAC is an antioxidant, it protects the cells of the body from the effects of free radicals. In addition, it takes part in the production of glutathione, which has been labeled the "Master Antioxidant". The caps are easy to swallow and don't have an aftertaste. I recommend this product.

Clean NAC at a good dose

The NAC capsules have a neutral smell, dissolve well, and seem to support general wellness. I like that the quantity lasts a while, though the bottle is quite large for what’s inside. Everything arrived sealed properly.

part of my daily stack

I've been taking The Vitamin Shoppe NAC 600 mg daily for about four months now. While I haven't noticed dramatic changes, I do feel a subtle sense of well-being. NAC is known for its antioxidant properties, supporting liver health and immune function. The package size is pretty big, but the capsules are easy to swallow, with a very mild odor.

First time NAC didn't smell like sulfur, hmmmm

I question why it didn't smell like sulfur like all the other NAC I have purchased, maybe I need to do more research. However,everything showed up as I imagined. The pills werent stuck together, the expiry date was in tact, and overall I like the brand. Thank you very much Iherb!
