The most effective hangover helpers are also the simplest: water, food, electrolytes, sleep, and time. No pill or supplement has been proven to cure a hangover, but understanding what’s actually happening in your body can help you choose strategies that speed up recovery and ease the worst symptoms.
Why Hangovers Feel So Bad
When your liver breaks down alcohol, it first converts it into acetaldehyde, a toxic compound that damages cells, triggers inflammation, and depletes your body’s natural antioxidant defenses. Your liver then converts acetaldehyde into a harmless substance, but this process takes time. While you wait, acetaldehyde and other byproducts circulate through your system, causing nausea, headaches, and that general feeling of being poisoned (because, technically, you are).
Alcohol also drops your blood sugar, which is why you feel weak, shaky, and exhausted the morning after. It suppresses a hormone that helps your kidneys retain water, so you urinate far more than usual and end up dehydrated. And it disrupts your sleep architecture, meaning even if you slept eight hours, the quality was poor. These overlapping effects are why hangovers hit from so many angles at once.
Hydration and Electrolytes
Rehydrating is the single most impactful thing you can do. Water works, but drinks with sodium and potassium (sports drinks, coconut water, or even broth) replace the electrolytes you lost overnight. Drinking a glass of water between alcoholic drinks the night before can reduce the severity significantly, though it won’t prevent a hangover entirely.
Food That Actually Helps
Eating before and during drinking slows alcohol absorption, giving your liver more time to keep up. The morning after, carbohydrate-rich foods like toast, crackers, or oatmeal help bring low blood sugar back up, which addresses the shakiness, fatigue, and mood dips that alcohol-induced blood sugar drops cause.
Eggs are a popular hangover food for a reason beyond tradition. They’re rich in an amino acid called L-cysteine, which reacts directly with acetaldehyde, the toxic byproduct your liver is working to clear. Researchers at the University of Helsinki found that L-cysteine supplementation alleviated hangover symptoms, likely through this mechanism. You don’t need a supplement for this. Eggs, yogurt, chicken, and other protein-rich foods are natural sources.
Bananas are another smart choice because they’re packed with potassium, one of the electrolytes you lose most of when drinking.
Pain Relief: What’s Safe and What’s Not
Ibuprofen or aspirin can help with headaches and body aches, but both irritate the stomach lining, which alcohol has already inflamed. Taking them with food reduces this risk.
Acetaminophen (Tylenol) requires more caution. Your liver processes both acetaminophen and alcohol, and both pathways produce toxic byproducts that your liver neutralizes with the same protective substance: glutathione. A single normal dose after a night of drinking is generally safe for most people. But if you drink heavily or regularly, combining repeated doses of acetaminophen with alcohol makes your liver more susceptible to damage. Acetaminophen toxicity accounts for nearly half of acute liver failure cases in North America. If you’re a regular heavy drinker, keep doses under 2,000 mg per day and use it sparingly.
Supplements and “Hangover Cures”
The supplement industry sells dozens of products claiming to prevent or cure hangovers. In 2020, the FDA sent warning letters to seven companies marketing hangover products, noting that none had been evaluated for safety or effectiveness. Products labeled as dietary supplements cannot legally claim to cure, treat, or prevent hangovers.
The scientific evidence behind popular remedies is thin. A systematic review published in the journal Addiction assessed 21 placebo-controlled trials of hangover treatments including red ginseng, prickly pear extract, clove extract, and Korean pear juice. While some individual studies showed improvements, the researchers rated all evidence as very low quality due to methodological problems and imprecise measurements. No two studies tested the same remedy, and no results have been independently replicated.
Dihydromyricetin (DHM), derived from the Japanese raisin tree, has generated interest for its effects on alcohol metabolism, but the strongest evidence comes from animal studies, not human trials. It may eventually prove useful, but right now the data isn’t there to recommend a specific dose or expect reliable results.
What You Drink Matters
Not all drinks produce equal hangovers. Darker spirits like bourbon, brandy, and whiskey contain higher levels of compounds called congeners, which are chemical byproducts of fermentation. One key congener is methanol, found in the highest concentrations in red wine, brandy, and whiskeys, and in the lowest concentrations in beer and vodka.
Research comparing bourbon and vodka at the same blood alcohol level found that hangover severity scores were significantly higher after bourbon. This doesn’t mean clear spirits are hangover-proof. Alcohol itself is the primary cause. But if you’re prone to bad hangovers, choosing lighter-colored drinks and avoiding sugary mixers (which speed absorption) can make a noticeable difference.
Sleep and Time
Your body clears alcohol at a fixed rate, roughly one standard drink per hour, and there’s no way to speed that up. Sleep is when your body does its best repair work, so letting yourself rest rather than pushing through the morning is genuinely productive. Alcohol disrupts deep sleep, so even a short nap the next day can help compensate for the low-quality rest you got overnight.
Coffee can help with the grogginess and caffeine-withdrawal headache that compounds a hangover, but it’s also a mild diuretic, so pair it with water. It won’t sober you up or accelerate alcohol metabolism.
The Most Effective Prevention Strategy
The only approach with solid evidence behind it is drinking less. Pacing yourself (one drink per hour), alternating with water, eating a full meal beforehand, and choosing lower-congener beverages collectively do more than any supplement. Hangovers scale with the amount of alcohol consumed and how fast you consume it. Everything else is damage control.
