Liver and alcohol metabolism
These target the toxic side of a hangover: alcohol and its byproduct acetaldehyde. DHM and the antioxidants support the liver enzymes and glutathione that clear them, and are taken around drinking, not the morning after.
Antioxidant and stomach support
Prickly pear has the best human hangover trial of any supplement here, easing nausea, dry mouth, and inflammation, and ginger settles an alcohol-irritated stomach.
Rehydration and B vitamins
Alcohol is a diuretic that flushes out water, B vitamins, and electrolytes, which drives much of the next-day fatigue and headache. Replacing them supports recovery.
Frequently Asked Questions
What is the best supplement for a hangover?
There is no magic cure, but the best-evidenced options are prickly pear (Opuntia) extract, which reduced hangover severity in a human trial, and DHM (dihydromyricetin), the traditional Hovenia dulcis flavonoid studied for supporting alcohol metabolism. NAC and B vitamins help with alcohol's byproducts and replenishment. Hydration and simply drinking less still matter most.
Does DHM (dihydromyricetin) actually work for hangovers?
The hype is ahead of the human evidence. DHM is well studied in animals, where it boosts alcohol-clearing enzymes and blunts intoxication, and human trials of whole Hovenia dulcis extract show some benefit for alcohol metabolism and stomach symptoms. But rigorous human hangover trials of DHM itself are limited, so treat it as promising rather than proven.
When should I take hangover supplements?
Timing matters. Most are taken around drinking, before or during, and again before bed with a big glass of water, since they target alcohol's metabolism and the resulting dehydration and depletion. Taking them only the next morning is less likely to help, and none of them work if you keep drinking heavily or speed up sobering up.
Does NAC help with hangovers?
Plausibly. NAC replenishes glutathione, the antioxidant the liver uses to neutralize acetaldehyde, the toxic alcohol byproduct linked to hangover symptoms. It is usually taken before drinking and is well tolerated. Direct human hangover trials are limited, but the mechanism is sound and NAC is a low-risk addition to the stack.
Do B vitamins and electrolytes help a hangover?
They address the depletion side. Alcohol is a diuretic that flushes out water, B vitamins, and electrolytes like potassium and sodium, which feeds the fatigue, headache, and grogginess. Replacing fluids and electrolytes, plus a B-complex, supports recovery, though they do not undo the toxic and inflammatory side that DHM, prickly pear, and NAC target.
Can any supplement make drinking safe?
No. No supplement prevents intoxication, impairment, or the long-term harms of alcohol, and none should ever be used to drink more or to justify driving. These options may ease some next-day symptoms, but the only reliable ways to avoid a hangover are to drink less, alternate with water, and not drink on an empty stomach. Seek help for any signs of alcohol dependence.
