NAC Reduces Alcohol Cravings, If Not Use
The antioxidant N-acetylcysteine (NAC) has been found to reduce many types of habitual behavior, from gambling to drug use to compulsive hair-pulling. A recent study by researcher Gihyun Yoon and colleagues, which was presented at a 2015 scientific meeting, found that while NAC and placebo reduced days of heavy drinking by about the same rates, NAC significantly reduced alcohol cravings and quality of life compared to placebo among participants with alcohol dependence.
In the 8-week study, 44 participants aged 18â65 received either 3600mg/day of NAC or a placebo. This dose of NAC was higher than the 600mgâ2400mg doses that have typically been used in research settings, and there were few side effects, confirming that NAC is a safe treatment.
The authors are not sure how NAC produces this effect, but it may be by regulating the neurotransmitter glutamate.
