300mg vs 1000mg DHM: Does the Dose Matter?
Browse DHM supplements and you’ll see serving sizes that span a wide range — some budget products use around 300mg, while others sit at 1,000mg or more. The ingredient on the label is the same flavonoid; the number beside it is what changes. This article lays out, factually, what dose the research has actually used, and is honest about where that evidence ends.

What the Doses Actually Are
Dihydromyricetin (DHM) is a flavonoid extracted from Hovenia dulcis, the Oriental Raisin Tree. Across the published literature and the consumer market, three reference points come up repeatedly:
- Research range: Studies on DHM have used doses spanning roughly 300–1,200mg (human-equivalent, where the source was an animal study scaled by body weight). There is no single “established” human dose — the literature is a range, not a settled number.
- Budget products: Many lower-cost DHM supplements use around 300mg per serving.
- Hovenia: Provides 1,000mg of DHM per serving (one serving = two capsules).
Those are facts about labels and study protocols. They are not, on their own, evidence that a higher number produces a better outcome — that’s a separate question the human research has not cleanly answered, and we won’t pretend it has.
What the Research Has Looked At
DHM has been studied for a few different reasons, and it helps to keep them separate rather than blend them into one “it works” story.
Alcohol-metabolizing enzymes (ADH and ALDH)
When the body processes alcohol, it uses two enzymes in sequence: alcohol dehydrogenase (ADH) converts ethanol into acetaldehyde, and aldehyde dehydrogenase (ALDH) converts that acetaldehyde into acetate. That two-step pathway is your own biology — it happens with or without any supplement.
Some studies have reported that DHM may influence the activity of these enzymes, but most of this work is in rodents or in cell models, and the human evidence is limited. It is fair to say researchers have examined this; it is not fair to say DHM “speeds up” or “detoxifies” anything in a person. We’re describing what’s been studied, not promising a result.
GABA-A receptors and next-day anxiety
A frequently cited paper is the 2012 study from UCLA published in the Journal of Neuroscience, which examined DHM’s effect on GABA-A receptor signalling in rodents. Alcohol potentiates GABA-A receptors; when it clears, receptor activity rebounds, and that rebound is associated with the jittery, anxious feeling some people get the next day. The UCLA work used rodent dosing and is one of the foundational mechanism studies — but it is an animal model, and a mechanism shown in rodents is a hypothesis about people, not a demonstrated human effect. For the neuroscience of why that rebound happens, see what causes a hangover and our explainer on DHM and GABA-A receptors.
Antioxidant activity
DHM is a flavonoid, and flavonoids are studied for antioxidant activity in lab settings. This is general category science and appears across a range of doses; it is not a claim that any supplement neutralizes anything in your body.
A note on what you won’t find here: some older write-ups attached DHM to “anti-aging” or cellular-senescence claims. We don’t make those. That’s drug-territory language, the human evidence isn’t there, and it has nothing to do with choosing a dose for the nights you drink.
A Factual Dose Comparison
Here is the comparison as numbers only — what doses appear where. Read it as a map of the landscape, not a ranking.
| Tier | Typical DHM per serving | Where it shows up |
|---|---|---|
| Budget | ~300–400mg | Many lower-cost single-ingredient DHM products |
| Mid | ~500–700mg | Various private-label and blended formulations |
| Higher | ~1,000–1,200mg | Hovenia (1,000mg) and the leading blended brands |
The research range (~300–1,200mg) brackets all of these. What the literature does not give us is a clean human trial showing that 1,000mg outperforms 300mg for a next-morning outcome in healthy adults who drink socially. So the honest framing is: 1,000mg sits at the higher end of the studied range; whether that translates to a better experience for you is not something the current evidence settles.
Why Hovenia Uses 1,000mg
Hovenia’s serving is 1,000mg of DHM — single ingredient, nothing else. No L-Cysteine, no milk thistle, no B-complex, no electrolytes, no proprietary blend. Two vegetable-cellulose vegan capsules make one 1,000mg serving.
We chose 1,000mg because it sits at the upper part of the range the research has used, and because the single-ingredient approach lets us put a full dose of one studied compound on the label without diluting it among other actives. That’s a deliberate design choice, framed honestly — it is one studied compound at a full dose, nothing else. It is a different approach from the multi-ingredient blends, not a claim to be more effective than them.
For how that fits into a daily-versus-occasional routine, see DHM and liver health.
What it costs at that dose
Because the comparison only makes sense on a per-equal-dose basis, here are the numbers:
| Brand | DHM per serving | Price per serving |
|---|---|---|
| Hovenia | 1,000mg | ~$1.00 (one-time); ~$0.83 on subscription |
| Cheers | 1,000mg+ | ~$2.92 |
| No Days Wasted | 1,200mg | ~$3.13 |
Same headline DHM dose as the premium blends, a fraction of the price, without the blend. Those are price and label facts; we’re not extending them into an efficacy claim.
How to Think About Dose for Your Situation
DHM is positioned for the nights you drink — a liver supplement for the occasion, daily use optional. The practical ritual Hovenia is built around is simple: two capsules (one 1,000mg serving) about 30 minutes before your first drink. That’s the whole night’s dose — there’s no “four capsules, two more before bed.” If you prefer daily use, that’s fine too, but the lead use case is occasion-first.
Dose isn’t the only variable that matters. DHM is generally taken with food, and timing relative to drinking is its own topic — see when to take DHM and taking DHM with food.
The Honest Bottom Line
- DHM research has used doses across roughly 300–1,200mg. That’s a range, not a verdict.
- Budget products around 300mg are real DHM at the lower end of that range; Hovenia’s 1,000mg sits at the higher end.
- The human evidence does not cleanly show that more DHM produces a better next-morning result, so we won’t tell you it does. We state the doses; you decide.
- Hovenia’s reason for 1,000mg is a single full dose of one studied compound, priced at ~$1/serving — a different, simpler approach, stated as a fact about the product, not a superiority claim.

Frequently Asked Questions
How much DHM should I take? There’s no official human dose — the research spans roughly 300–1,200mg. Hovenia provides 1,000mg per serving (two capsules), which sits at the higher end of the studied range. Talk to your healthcare provider about what’s appropriate for you.
Is 1,000mg of DHM better than 300mg? We can’t honestly say so. 1,000mg is a higher dose within the studied range, but the human evidence doesn’t cleanly show a higher dose produces a better outcome for social drinkers. The dose numbers are facts; “better” is not something the research settles.
Is 300mg of DHM a waste of money? No. 300mg is real DHM at the lower end of the range studies have used. It’s simply a smaller dose than products like Hovenia, which uses 1,000mg. Which you choose depends on your preference and budget, not on a proven efficacy gap.
Why is Hovenia single-ingredient instead of a blend? It’s a design choice: one studied compound (DHM) at a full 1,000mg dose, with nothing else in the capsule. That’s different from the multi-ingredient blends — not a claim to be more effective, just a simpler approach.
When do I take it? The Hovenia ritual is two capsules (one 1,000mg serving) about 30 minutes before your first drink — that’s the night’s full dose. See when to take DHM for more.
