Stanford Chemicals sells only the highest quality Dihydromyricetin (DHM) and stand behind our product. Our DHM is manufactured in the United States, and is rigorously tested for purity and effectiveness.
Dihydromyricetin (DHM or DMY), sometimes called Ampelopsin or Ampeloptin, is a natural antioxidant flavonoid from the Chinese vine tea plants (Ampelopsis grossedentata).
As an active herbal ingredient of the dihydromyricetin extract, it shows very promising results among hangover cures and has a significant protective effect against alcohol-induced liver damage.
Dihydromyricetin can work as an active free radical scavenger. The percentage inhibition of DPPH could reach 73.3%-91.5% with the IC50 value of 5.4 mmol/L. It markedly attenuates the activity of superoxide anion generation. It also has the strong inhibitory action of Staphylococcus aureus, Bacillus subtilis Aspergillus flavus, etc. New applications have been confirmed recently that dihydromyricetin can reduce anxiety, the levels of blood sugar and blood fat; anti-inflammation; effective restraint cell proliferation of some tumor cells.

List of Dihydromyricetin Benefits
Dihydromyricetin (DHM) is an organic compound naturally found in the Raisin Tree. It’s often called by it is Latin classification Hovenia Dulcis, and is found all over Asia. As a deciduous tree, it grows up to 12m tall, and bears a berry-like fruit that tastes similar to raisins, from which it gets its name. The molecule we know as Dihydromyricetin is also called Ampelopsin, and is extracted using an ethanol-based solution from the bark of the Hovenia Dulcis tree, and minimally processed before it’s dehydrated and turned into a powder ready to be purified.
When you take dihydromyricetin really depends on what you’re trying to accomplish. So, for example, researchers found that taking a relatively large dose before drinking it reduced the circulating levels of alcohol in the blood. For most people however, we recommend taking it immediately after drinking which works very well to reduce the hangover symptoms usually felt the next day and stops the GABA rebound effect that will often wake you up in the middle of the night or give you anxiety the next day.
Yes. For both reducing intoxication, and for reducing the effects of a hangover and supporting the liver, there is ample scientific evidence. The question really is, at what dose does it work? And for that the answer is slightly different and varies by the number of drinks you’ve had, their alcohol content, whether you’ve eaten and so on. It also depends on what you’re looking to achieve with DHM, since reducing intoxication requires significantly higher doses, than when taken after drinking to eliminate hangovers.
Not really. DHM will reduce the impact alcohol has on your central nervous system (by down-regulating GABA transmission) which means you may be more co-ordinated and less likely to have slurred speech if you take Dihydromyricetin when consuming alcohol.
Theoretically, yes. Doses to reduce circulating alcohol content need to be relatively large — in the 3g+ range for humans — and you still won’t be safe to drive no matter what, and doing so would be illegal. Large doses of the supplement will indeed make you feel less drunk, but it is not certain whether this is because the anti-alcohol effect is strong enough by itself or whether the additional reduction in the neurotransmitter GABA provides an additive effect.
DHM supports alcohol metabolism, protects the liver, reduces oxidative stress, and may improve brain health by mitigating alcohol-induced damage.
In skincare, DHM provides antioxidant benefits, helps reduce inflammation, and may protect against environmental damage, promoting healthier skin.
