After Party by Fuller Health is a single-ingredient DHM supplement: 650 mg of dihydromyricetin per capsule, 3,250 mg per 5-capsule serving, with nothing else but the cellulose capsule. We made it that way so the label tells you exactly what you're taking and how much. One ingredient is a choice about transparency; it isn't evidence that a product does anything.
Key takeaways
- Each After Party capsule contains 650 mg of DHM, and the only other ingredient is the vegetable cellulose capsule.1
- U.S. labeling rules let a proprietary blend list just its total weight, with ingredients such as botanicals in order of weight but not their individual amounts.2
- DHM can make up as much as 35% of vine tea (Ampelopsis grossedentata), the plant After Party's DHM is extracted from.3
- One 3,250 mg serving is about 3.4 times the highest daily DHM dose in a published human trial, 970 mg.4
Why does After Party contain only DHM?
Because we wanted a label you can read in five seconds: one active ingredient, one amount, one capsule material, nothing to decode.
With one ingredient at a stated dose, you know exactly what you're taking. You can look it up, compare amounts across products, and show the label to your doctor or pharmacist for a straight answer. Ten ingredients, some at undisclosed amounts, make all of that harder.
Fuller Health, the company that makes After Party, was founded by Mikhaila Fuller (formerly Mikhaila Peterson).
What does "single ingredient" mean on our label?
It means one dietary ingredient, dihydromyricetin (DHM), at 650 mg per capsule, in a capsule made of vegetable cellulose.1 There's no second active ingredient, no proprietary blend, and no fillers or flow agents.
Dihydromyricetin (DHM) is a flavonoid, a type of plant compound, also called ampelopsin.5 Ours is extracted from the stem and leaf of vine tea (Ampelopsis grossedentata), a plant brewed as an herbal tea in China for hundreds of years.6 For more on the compound, see what DHM is.
| Label item | Per capsule | Per serving (5 capsules) |
|---|---|---|
| Dihydromyricetin (DHM), from vine tea stem and leaf | 650 mg | 3,250 mg |
| Other ingredients | Vegetable cellulose capsule | Vegetable cellulose capsules |
| Proprietary blend | None | None |
| Fillers or flow agents | None | None |
| Sugar | 0 g | 0 g |
| Dietary | Vegan, gluten-free | |
What did we leave out, and why?
Everything that isn't DHM: no vitamins, electrolytes, amino acids, other botanicals, sweeteners, fillers or flow agents. Here's the reasoning.
- No proprietary blend. U.S. rules let a "proprietary blend" list ingredients that have no Daily Value, such as botanicals, in descending order of weight with only the blend's total weight, not each ingredient's amount.2 That's legal, but it means you can't tell how much of any one ingredient you're getting. We'd rather print the number. More in proprietary blends explained.
- No add-ons for a longer label. Each extra ingredient is one more thing to research, one more possible interaction with a medicine, and one more suspect if you have a reaction.
- No fillers or flow agents. Some capsules include extra powders to bulk them up or help them fill evenly. Ours contain DHM and the capsule, nothing else.
- No sweeteners or flavors. It's a capsule, so there's nothing to flavor, and it has 0 g sugar.
What doesn't "single ingredient" mean?
It doesn't mean proven. A short ingredient list is a fact about the label, not evidence about what a product does in your body.
- It isn't proof of effect. The FTC expects health claims to rest on competent and reliable scientific evidence, generally randomized trials in people using the same ingredient at the same dose.7 One ingredient doesn't change that standard, and we don't make health claims for After Party.
- A higher dose isn't a benefit. The 3,250 mg serving is a fact about the label. It's about 3.4 times the highest daily DHM dose tested in a published human trial, 970 mg a day for one month in adults with type 2 diabetes, and human safety at our dose hasn't been studied.4
- It isn't automatically low-risk. In lab tests on human enzyme samples, DHM inhibited CYP3A4, CYP2D6 and CYP2E1, enzymes that process many prescription drugs. That hasn't been tested in people, but it's why you should ask a pharmacist first if you take medicines.8
- It isn't for everyone. After Party is not for use during pregnancy or breastfeeding and is for adults 21 and over. Ask a doctor first if you have a liver condition or any other medical condition.
Where does our DHM come from?
From vine tea, Ampelopsis grossedentata, stem and leaf. It's the richest known source: DHM can make up as much as 35% of the plant.3
Many products and articles say DHM comes from the Japanese raisin tree, Hovenia dulcis. That tree contains DHM too, but when the European Food Safety Authority assessed a commercial hot-water extract of its fruit and stalks, it was about 90% carbohydrate, with only small amounts of flavonoids such as DHM.9 Research on those extracts isn't research on purified vine-tea DHM; the differences are in vine tea vs. Hovenia dulcis.
Our published certificate of analysis reports 3,250 mg of DHM (one serving's worth) against a minimum of 3,250 mg, with heavy metals and microbes reported as within its limits. It covers a lot made in June 2023, best by June 2026, and doesn't name the testing lab; the details and caveats are in how After Party is sourced and tested.10
How do you read the After Party label?
Three lines tell you nearly everything: serving size (5 capsules), DHM (3,250 mg per serving) and other ingredients (cellulose capsule). Then check the directions, 3 capsules before bed and 2 upon waking, and the cautions. The full Supplement Facts panel is on the After Party facts page, and our guide to reading a supplement label works for any product.
What we don't know yet
As of October 2026, we found no published human study of DHM at 3,250 mg per serving, of how DHM is absorbed in people, or of how it interacts with specific medicines in people. A single-ingredient label makes those questions easier to ask. It doesn't answer them.
Frequently asked questions
What's in After Party?
Dihydromyricetin (DHM) from vine tea, 650 mg per capsule, in a vegetable cellulose capsule. That's the whole ingredient list. One serving is 5 capsules, or 3,250 mg of DHM.
Does After Party contain any fillers or flow agents?
No. After Party contains no fillers, flow agents or proprietary blend. The only ingredient besides DHM is the cellulose capsule.
Why doesn't After Party include vitamins or electrolytes?
Because we wanted one ingredient you can identify, look up and discuss with your doctor; every addition is another variable. If you want vitamins or electrolytes, buy them separately so you know exactly what you're getting.
