We’ve all been there: the pounding headache, nausea, fatigue, and regret after a night of heavy drinking. Hangovers can ruin your entire next day, but the good news is that science offers real, evidence-based strategies to prevent them — or at least make them far less brutal. While no magic pill exists yet, smart choices before, during, and after drinking can make a huge difference.

Latest update (December 2025): A groundbreaking genetically engineered probiotic from ZBiotics has now sold over 10 million bottles. A 2024 peer-reviewed study suggests it helps break down acetaldehyde (a toxic alcohol byproduct) in the gut, potentially reducing hangover severity — and even showing promise for liver health.

Preventing a Hangover
1. Choose Drinks Low in Congeners
Congeners are toxic byproducts formed during alcohol fermentation. Darker spirits like bourbon, whiskey, tequila, and cognac are loaded with them, while clear ones like vodka, gin, and light rum have far fewer.
Studies show high-congener drinks worsen hangover severity and slow alcohol metabolism. In one classic experiment, participants who drank bourbon reported significantly worse symptoms than those who drank the same amount of vodka. Stick to clearer spirits if you want an easier morning.
2. Stay Seriously Hydrated
Alcohol is a diuretic — it makes you pee out more fluid than you take in, leading to dehydration that fuels thirst, dizziness, headaches, and fatigue.
The simplest fix? Alternate every alcoholic drink with a glass of water. Keep drinking water the next day, and consider electrolyte-rich options (coconut water or sports drinks) to restore sodium and potassium. This alone can cut many symptoms dramatically.
3. Prioritize Sleep
Alcohol disrupts your sleep cycle, even if it knocks you out initially. Poor sleep amplifies fatigue, irritability, and brain fog the next day.
Give your body time to recover with a full night’s rest. Avoid late-night drinking when possible, and create a calm wind-down routine. Sleep won’t erase a hangover, but lack of it will make everything feel twice as bad.
Ways to Relieve an Existing Hangover
4. Eat a Nutrient-Rich Breakfast
Alcohol depletes vitamins, minerals, and stable blood sugar. A hearty breakfast helps restore balance and reduces nausea, weakness, and shakiness.
Focus on eggs (rich in cysteine, which helps break down acetaldehyde), whole grains, nuts, avocados, and zinc-rich foods. Avoid super-greasy meals if your stomach is upset — opt for toast, oatmeal, or a smoothie instead.
5. Consider Evidence-Based Supplements
Research is still emerging, but some supplements show promise:
- Red ginseng — reduced blood alcohol levels and symptom severity in older studies.
- Prickly pear cactus extract — cut severe hangover risk in half in one trial.
- Ginger — eases nausea and may protect the liver.
- DHM (from Hovenia dulcis) — popular in modern supplements; speeds alcohol breakdown.
- New probiotic options — like ZBiotics (mentioned above) target acetaldehyde directly.
Results vary, and more high-quality research is needed, but these are among the most studied.
6. Use Pain Relievers Wisely
NSAIDs like ibuprofen or aspirin can ease headache and muscle aches. One small study found a naproxen/antihistamine combo significantly reduced overall severity.
Never take acetaminophen (Tylenol) — it stresses the liver when combined with alcohol. If you have stomach pain or nausea, skip NSAIDs too, as they can irritate the gut.
The Bottom Line
The only foolproof hangover cure is moderation (or abstinence), but these six strategies — backed by science — can dramatically reduce suffering. Drink smarter, hydrate relentlessly, eat well, sleep, and consider targeted supplements. Your future self will thank you.
And with emerging innovations like genetically engineered probiotics gaining traction in 2025, the mornings after nights out may soon feel a lot less punishing.
