NAC is a unique substance that promotes glutathione production in the liver, cell regeneration, and support for detoxification, removing toxins, waste, and heavy metals. It perfectly facilitates the breakdown and removal of alcohol breakdown products, making this indispensable product ideal for relieving hangover symptoms. It supports all liver functions. The combination with selenium and molybdenum enhances and improves the effects of Detoksa. I recommend it to everyone for liver and digestive system support. The manufacturer is trusted, and the price is simply amazing. If my review was helpful, please click Yes. Thank you!

Great product
I combine this in the morning with Glycine. Not only is NAC great for respiratory, but combining with Glycine gives a nice, clean focused energy.

I can breathe!
After years of sinus issues, I added this to my daily supplements. I have been able to stop taking otc meds. Any time I can replace synthetic meds with natural remedies, it’s a win.

EVERYDAY first thing in the morning on an empty stomach!
Excellent quality and good strength. The capsule is not very large, so easy to swallow. I like the quantity of 240 capsules so I don't have to worry about reordering so soon. NAC is an anti-inflammatory, anti-oxidant and helps to increase glutathione at the cellular level.

NAC is valued largely for its role in the synthesis of other antioxidants. Together with two amino acids (namely, glutamine and glycine), this substance ensures the creation of glutathione and the replenishment of its stores.

Works like magic!
I take NAC along with ALA, and they work amazingly well together. Using NAC and ALA has been one of the best things I’ve ever done for myself. I discovered these two molecules thanks to iHerb and decided to start taking them after doing a bit of research. The effects showed up within the very first week. I can breathe more easily, my energy levels have noticeably increased, my joint pain has decreased, I feel full with smaller portions, and my sugar cravings have dropped. Best of all, when something bothers me, instead of going to sleep, I put on my headphones and work out 😍 I recommend this combo to everyone I talk to 💫💫💫

Enjoying so far
Time will tell if this will help clear melasma. It is supposed to be supportive for that. I will definitely update the review with what I notice over time.
