NOW NAC 600mg

Antioxidant support, liver health, respiratory health, glutathione production.. The N-Acetyl Cysteine dose is clinical for many uses. However, the selenium inclusion is too low to be effective. This underdosing of a secondary ingredient limits the overall product score.

8.0/10
EXCELLENT

NAC at 600mg hits the minimum effective dose and is the standard single-dose amount used in respiratory studies. Selenium at 25mcg is a thoughtful support addition (antioxidant synergy with NAC) though below its 55mcg minimum. Per masterprompt rules, underdosed support cannot subtract. Two caps daily would reach optimal 1200mg.
