Why NAC Before Drinking Might Help You Feel Better the Next Day

Although there’s not much you can do to cure a hangover once it’s already happened, taking the supplement N-acetyl cysteine (NAC) can help your body break down alcohol more effectively, which may minimize unpleasant post-drinking symptoms.

Taking NAC can’t entirely prevent alcohol-related symptoms, but it does support your body’s ability to produce antioxidants that break down toxic byproducts of alcohol such as acetaldehyde. This means your body can do a better job of neutralizing those toxins as you drink—resulting in fewer post-drinking symptoms the next morning.

Along with hydration and moderate drinking, taking NAC can help you bounce back from post-drinking symptoms sooner. Read on to learn what makes NAC such an effective support for the body when consuming alcohol.

How Taking NAC Before You Drink Reduces Post-Drinking Symptoms

N-acetyl cysteine (NAC) is a form of the amino acid cysteine that’s often taken as a supplement. It supports the body’s ability to produce glutathione, a powerful antioxidant that’s crucial for detoxification, including the breakdown of acetaldehyde and other toxic byproducts of alcohol.

Glutathione has a range of benefits for those who drink alcohol habitually: it neutralizes free radicals (which can contribute to oxidative stress) and may help minimize liver cell damage. For regular drinkers, these benefits can improve the body’s ability to break alcohol down over time.

Why Timing Matters: Prevention vs. Recovery

It’s important to take NAC before you drink to minimize post-drinking symptoms. It’s not NAC itself that breaks down alcohol’s toxic byproducts—it’s glutathione. By taking NAC an hour or two before drinking, you give your body time to increase glutathione levels so it can neutralize acetaldehyde as alcohol is metabolized.

Although taking NAC after drinking can still support recovery, only taking it before drinking can help prevent the buildup of acetaldehyde that leads to hangover symptoms.
