What Is DHM?
DHM stands for dihydromyricetin — a flavonoid extracted from the Japanese Raisin Tree (Hovenia dulcis). It's been used in East Asian traditional medicine for centuries, specifically to reduce the effects of alcohol. Modern supplement brands have picked it up as the headline active ingredient in hangover prevention products.
What Does DHM Do?
DHM is included in hangover supplements for its alcohol metabolism support properties. The proposed mechanism involves how the body processes ethanol — your liver breaks alcohol down into acetaldehyde, a toxic intermediate, before converting it into harmless acetate. The theory is that DHM supports this process.
DHM has also been researched for its interaction with GABA receptors — the same receptors that alcohol affects. This is relevant to "hangxiety," the next-morning anxiety that many drinkers experience. Some users report that DHM notably reduces this effect.
What the Research Says
Human clinical trials on DHM for hangover prevention are still limited. Much of the existing research is preclinical (animal models), which is promising but not conclusive. What is well established is the traditional use record — Hovenia dulcis has been used for over a thousand years in Chinese medicine specifically for alcohol-related symptoms.
Anecdotally, DHM has built a strong word-of-mouth reputation in supplement communities. The majority of people who try it report a noticeable improvement in how they feel the next morning.
No hangover supplement — including those containing DHM — has been proven to prevent hangovers in large-scale human trials. The supplement works for many people but results vary. Revive backs this with a 30-day money-back guarantee.
How to Use DHM Effectively
The timing matters. Take DHM before bed, right after your night out, with at least one full glass of water. Some people double up — one dose before drinking, one before bed. The key is not waiting until morning.
Hydration is still important. DHM doesn't replace water — it works alongside it. A big glass of water with your Revive capsules before bed is part of the routine.
