N-Acetyl Cysteine (NAC) is a stable form of the non-essential amino acid cysteine.

Powerful Antioxidant Support – NAC + Selenium Combo That Works
Verified Purchase
Rewarded review
This NAC supplement is excellent quality and very effective. The 600 mg dose provides strong antioxidant support, and the addition of selenium is a great plus since it works synergistically to protect cells and boost glutathione production. I’ve noticed better energy, improved immune resilience, and overall wellness since adding this to my routine. The capsules are easy to take, and I trust NOW Foods for their consistency and clean formulas. With 100 capsules per bottle, it’s also a great value for long-term use. A must-have supplement for detox, immunity, and cellular health.

Rewarded review
NAC600mg has an antioxidant effect and can be taken as one tablet per day. A friend recommended it to me for improving free radical scavenging and expectoration. After taking it for a while, I feel that it does help clear phlegm. Now I am trying to see if it can reduce dark spots.

You can eat it before and after exercise, even before a big meal or drinking. Eating it before exercise is highly recommended. If you are curious, you can talk to GPT about the difference between eating it before and after. But first, you need to know what your purpose is.
