What to Take for a Hangover: The Supplements With Evidence, and What to Skip

There is no true cure for a hangover. Time is the only thing that finishes one. What the right fluids, food, and supplements can do is reduce how severe it feels and help your body recover a little faster. Of the many hangover remedies people reach for, only a handful have evidence worth acting on. The Agape team keeps the answer honest: here is what to take, what dose the evidence supports, what to skip, and how to prevent the next one.

Why a hangover hits so hard

A hangover is not one problem. It is several happening at once, and that is why no single remedy fixes it. When you drink, a few things stack up:

• Dehydration and lost electrolytes. Alcohol makes your body pass more water and minerals than usual.
• Acetaldehyde. Your liver turns alcohol into this toxic byproduct before clearing it.
• Inflammation and oxidative stress. These drive the headache and the overall sick feeling.
• Broken sleep. Alcohol knocks you out, but the sleep is shallow and restless.
• Low blood sugar and irritation in the gut. Both add to the nausea and fatigue.

If you can tackle the biggest of these, you can meaningfully soften the morning.

What to take for a hangover

No supplement cures a hangover. Some have real, if mixed, evidence for reducing severity. Here is the graded shortlist, with the dose that fits the evidence.

NAC

N-acetylcysteine, or NAC, is the one people ask about most, and the trials so far are disappointing. A randomized trial (Coppersmith, 2021) tested 600 to 1,800 mg and found no significant difference in overall hangover scores, with a signal only in a subgroup of women. A later clinical study (Podobnik, 2024) found no relief from NAC either. That is worth knowing before you spend money. NAC is a glutathione precursor, so it supports your liver's normal handling of alcohol byproducts as everyday liver nutrition, but do not buy it expecting a hangover fix. For more on how it works, see our full NAC guide. If you want it anyway, our listing is DaVinci Labs N-Acetyl Cysteine 500 mg.

Electrolytes, not just water

Plain water alone under-replaces what alcohol flushed out. Alcohol suppresses a hormone called vasopressin, so your kidneys pass more water and electrolytes than usual. Replacing both is the point. Take one serving of an electrolyte mix with real sodium and potassium, ideally before bed and again in the morning. This is one of the most reliable moves on the list. See our electrolyte supplements guide for what to look for on a label. Our pick for this is Pure Encapsulations Electrolyte / Energy Formula, a powdered electrolyte drink mix.

Ginger for the nausea

Ginger's strong evidence is for nausea in general, not for hangovers specifically. Its track record against nausea in pregnancy is solid, and that translates reasonably to the queasy half of a hangover. Trial doses have ranged from 450 to 1,950 mg a day, most often around 500 to 1,000 mg. Take it at the first sign of stomach upset. If nausea is your worst symptom, this is where ginger earns its place. Our nausea and motion sickness remedies guide covers the broader picture, and our digestion and GI support collection has staples for an upset stomach. Our pick for the nausea half is Pure Encapsulations Ginger Extract.

B vitamins and zinc

One dietary study found that people with higher zinc and niacin (vitamin B3) intake also reported lower hangover severity. That is an observation, not proof of cause and effect, and it is worth saying plainly. Alcohol also depletes B vitamins, so a standard B-complex plus about 8 to 11 mg of zinc (the daily requirement) is reasonable, low-cost support. Do not expect it to erase a hangover on its own.

Milk thistle

Set expectations: milk thistle is a liver-support ingredient, not a hangover cure. Its active compound, silymarin, has real evidence for supporting healthy liver enzymes. That is a longer-term foundation, not a same-morning rescue. A common liver-support dose is 200 to 400 mg of a standardized silymarin extract daily. It is general liver support rather than a shield against a night of drinking, so treat it that way. See our milk thistle guide and our broader liver support supplements guide. Our pick for this is Natural Factors Milk Thistle Phytosome, a milk thistle formula for liver support.

What to skip

Some classic remedies make things worse or do nothing. Skip these:

• Hair of the dog. More alcohol delays the hangover and adds to the load your liver has to clear. It buys you a worse tomorrow.
• Acetaminophen (Tylenol) while alcohol is still in your system. The combination is hard on your liver. If you need a pain reliever, ibuprofen is the safer alternative, though it can still irritate your stomach. Take it with food and water.
• Activated charcoal after the fact. Charcoal works by binding substances in the gut. Once alcohol is absorbed into your blood, charcoal has nothing left to grab, so taking it the morning after will not touch the hangover.

How to prevent a hangover

The best hangover remedy is not having one. The evidence points to the same few habits every time:

• Pace to one drink per hour. Your liver clears roughly one standard drink in that time.
• Eat before you drink. Food slows alcohol absorption.
• Alternate each drink with a glass of water to stay ahead of the dehydration.
• Choose lighter drinks if you are sensitive. Dark liquors carry more congeners than clear spirits, and many people report worse hangovers from them, though the research is mixed.

None of this is glamorous, but it works better than any supplement after the fact.
