Botanical source
Dihydromyricetin occurs in Ampelopsis grossedentata, commonly called vine tea, and in Hovenia dulcis, the Japanese raisin tree. Source identity and standardization matter when comparing ingredients.
Dihydromyricetin
What is DHM?
The science of dihydromyricetin.
A clear guide to the molecule, the research, and the limits of what anyone should claim.
Short answer
DHM is a plant flavonoid found in vine tea. Researchers have studied it in alcohol-related, antioxidant, metabolic, and neural-signaling models. Much of the evidence is preclinical, so a mechanism in a cell or animal is not the same as a proven finished-product result in people.
The molecule
One ingredient. Several evidence layers.
Molecule
DHM is a flavonoid. The name on a label does not tell you its source, purity, formulation, or how much reaches circulation.
Research model
Cell, rodent, and limited human evidence should be labeled separately. They do not carry the same certainty.
What researchers are actually studying.
Pathways are not promises. Each finding needs its model, dose, route, and endpoint attached.
Preclinical studies examine enzymes involved in the conversion of ethanol to acetaldehyde and then acetate. Findings are not a shortcut around time.
The widely cited 2012 UCLA paper used rodent and cell models. It did not test a finished Joyrise product in a human clinical trial.
Researchers have examined antioxidant-response and autophagy pathways, mostly in preclinical settings. Human outcome evidence remains limited.
Why formulation matters
DHM on a label is only the beginning.
Raw DHM has known solubility and absorption challenges in preclinical research. Joyrise uses a patented delivery approach designed around bioavailability. The patent protects an invention. It does not guarantee that every person will experience the same result.
- Compare source and formulation
- Read the exact serving directions
- Ask whether evidence is human, animal, or cell
- Keep responsible-use limits visible

DHM questions, answered plainly.
What is DHM?
DHM, or dihydromyricetin, is a naturally occurring flavonoid found in plants including vine tea and Japanese raisin tree.
What has DHM been studied for?
Researchers have studied DHM in alcohol-related pathways, GABA-A signaling, oxidative-stress responses, and metabolic models. Much of the alcohol-related evidence is from cells and animals.
Does DHM lower BAC or make drinking safe?
No. DHM does not lower BAC or impairment, does not make drinking safer, and must never be used as a reason to drive after drinking.
Are all DHM supplements the same?
No. Source, dose, delivery system, other ingredients, format, testing, and directions can differ. Compare the current labels, not only the front-of-pack milligram number.
Ready to compare formats?
Bottle, packets, or powder.
Joyrise does not reduce impairment or BAC and does not make drinking safer. Never drink and drive.
