The most effective way to minimize a hangover is to slow your drinking, eat before and during, hydrate between drinks, and choose lighter-colored spirits. No single trick eliminates hangovers entirely, but combining several evidence-backed strategies can significantly reduce how rough you feel the next morning. Here’s what actually works and why.
Why Hangovers Happen in the First Place
Your liver breaks alcohol down into a toxic byproduct called acetaldehyde before converting it into harmless acetic acid. When you drink faster than your liver can keep up, acetaldehyde accumulates. Research shows this compound drives mitochondrial dysfunction in brain cells, reducing energy production by roughly 50% and impairing oxygen use by about 30%. That’s a big part of why you feel foggy, exhausted, and slow the next day.
But acetaldehyde isn’t the whole story. Alcohol suppresses a hormone that helps your kidneys retain water, so you urinate far more than the volume you’re drinking. It also triggers an inflammatory immune response throughout your body, similar to what happens when you’re fighting off an infection. The combination of dehydration, inflammation, disrupted sleep, and lingering acetaldehyde creates the familiar constellation of headache, nausea, fatigue, and brain fog.
Eat Before You Drink
Food in your stomach slows the rate at which alcohol enters your bloodstream. This gives your liver more time to process each wave of alcohol, keeping acetaldehyde levels lower. A meal with fat, protein, and complex carbohydrates works best because it takes longer to digest. Think a burger, a bowl of pasta with olive oil, or eggs and avocado toast. Drinking on an empty stomach is one of the fastest routes to a severe hangover because alcohol hits your system all at once.
Hydrate Strategically
The classic advice to “drink water between drinks” holds up for good reason. Alcohol forces your kidneys to excrete excess fluid, carrying minerals like sodium, potassium, and magnesium with it. Alternating one glass of water for every alcoholic drink slows your overall pace and replaces some of the fluid you’re losing in real time.
Electrolyte drinks can help more than plain water because they’re designed to be absorbed quickly in the gut and replace the minerals you’re flushing out. You don’t need anything fancy. A sports drink, coconut water, or a glass of water with a pinch of salt and a squeeze of citrus before bed all work. The key is not waiting until the morning, when dehydration has already set in. Drink fluids before you sleep and again when you wake up.
Choose Your Drinks Wisely
Not all alcoholic drinks produce equal hangovers, even at the same alcohol content. The difference comes down to congeners, which are chemical byproducts of fermentation and aging. Darker spirits contain far more of them. Bourbon, for example, contains several times more of certain congeners (like isobutanol, at 400 to 600 milligrams per milliliter) compared to scotch or Irish whiskey. Vodka is considered the “cleanest” spirit, with the lowest congener load and the mildest hangover profile at equivalent doses.
Red wine and dark rum also rank high on the congener scale. If you’re trying to minimize next-day misery, lighter-colored drinks are the better bet. Mixing different types of alcohol doesn’t cause worse hangovers on its own, but it does make it harder to track how much you’ve consumed, which usually means you drink more.
Pace Yourself and Set a Limit
Your liver processes roughly one standard drink per hour. Every drink beyond that rate adds to the acetaldehyde backlog. Spacing your drinks out, using smaller pours, and setting a number before you start are the most straightforward ways to keep your blood alcohol from spiking. Two to three drinks over an evening with food and water is a very different experience from four or five in two hours.
Nutrients That Support Alcohol Metabolism
Alcohol depletes several vitamins and minerals your body needs to break it down efficiently, creating a vicious cycle. Zinc is particularly important because it’s required for the enzyme that converts alcohol into acetaldehyde. Low zinc levels slow alcohol clearance. Vitamin B6 is actively destroyed in the presence of acetaldehyde itself, while B1, B2, B3, B9, and vitamin C are all depleted with alcohol intake. Magnesium and selenium levels drop as well.
You don’t need a special supplement protocol. A solid meal before drinking and a B-complex vitamin can help ensure your liver has the raw materials it needs. Some people take a multivitamin with zinc before a night out. The evidence is stronger for preventing nutrient depletion in the first place than for popping vitamins as a cure the morning after, when the damage is already done.
Supplements With Mixed Evidence
Dihydromyricetin (DHM), derived from the Japanese raisin tree, is one of the most popular “anti-hangover” supplements. Animal studies have been promising, but as of 2024, no controlled human studies have been published confirming its safety, optimal dose, or effectiveness. Phase 1 trials are underway to determine basic dosing in humans. It may eventually prove useful, but right now you’re essentially experimenting on yourself.
Prickly pear extract has slightly better human data. In a controlled trial, people who took it before drinking reported less nausea, loss of appetite, and dry mouth compared to placebo. However, it did nothing for headache, weakness, shakiness, dizziness, or diarrhea. It’s a partial solution at best.
Be Careful With NAC Timing
N-acetylcysteine (NAC) is a supplement that boosts your liver’s stores of glutathione, a key antioxidant for processing alcohol. It’s widely recommended in hangover-prevention circles, but timing matters enormously. Animal research found that NAC taken before drinking protected the liver by counteracting oxidative stress. When given after alcohol exposure, however, NAC acted as a pro-oxidant and actually worsened liver damage in a dose-dependent way. If you’re going to use NAC, take it before your first drink, not the morning after.
Pain Relief the Next Morning
If you wake up with a hangover headache, your choice of painkiller matters. Acetaminophen (Tylenol) and alcohol are both processed by the liver, and combining them can strain it. For occasional drinkers who take a couple of standard doses the next day, the risk is generally low. But if you drink heavily or regularly, you should keep acetaminophen doses under 2,000 mg per day, well below the normal 4,000 mg daily maximum. Chronic heavy drinking depletes the liver’s glutathione stores, making it far more vulnerable to acetaminophen toxicity, which is responsible for nearly half of acute liver failure cases in North America.
Ibuprofen (Advil) or naproxen (Aleve) are often safer choices for hangover headaches since they don’t tax the liver the same way, though they can irritate an already-sensitive stomach. Taking them with food and water helps.
Sleep and Recovery
Alcohol fragments your sleep architecture, reducing the deep and REM sleep stages your brain needs to recover. Even if you’re unconscious for eight hours after drinking, you wake up less rested. You can’t fully fix this, but you can avoid making it worse. Stop drinking at least two to three hours before bed to give your body a head start on processing. Keep your room cool and dark, and don’t set an alarm if you can avoid it. Letting your body sleep until it naturally wakes up gives it extra time to clear acetaldehyde and rehydrate.
The morning after, prioritize a meal with eggs (which contain an amino acid that helps break down acetaldehyde), complex carbs to stabilize blood sugar, and plenty of fluids. Light movement like a walk can help, though intense exercise while dehydrated and inflamed is counterproductive.
