How much hops should you take a day?
There's no official recommended dose for hops. The clearest human dosing data comes from small appetite trials testing 100-500 mg of a concentrated bitter hop extract, a different, more processed preparation than a typical standardized-extract or whole-flower capsule.
There's no official recommended dose of hops, unlike vitamins and minerals with a government-set intake range. The clearest human dosing data comes from a small set of appetite trials testing 100-500 mg of a concentrated bitter hop extract — a different, more processed preparation than a typical over-the-counter hops or valerian-hops capsule.
What the appetite trials actually tested
Four small randomized trials, all using variations of a concentrated bitter hop extract, give the most specific dose data available. A 2022 crossover trial in 19 men used a single 500 mg dose, the highest single amount tested, and found reduced food intake at a following meal (PMID 35102364). Two trials — one in 30 women, one in 30 men — used 100-250 mg doses, given twice in a day during a 24-hour fast, and both found reduced hunger or cravings at those amounts (PMID 39071168, PMID 31766216). A fourth trial tested single 100 mg and 250 mg doses and found no appetite-suppressant effect at all under its particular protocol — the same milligram range that worked in other trials didn't reproduce there (PMID 36781111). See hops benefits: what the research does and doesn't show for what each of these trials found in full.
Sleep-focused products: doses that weren't published
Two trials most relevant to hops and sleep didn't publish a specific milligram amount for the hops component. A 2010 trial dosed a hops-plus-fish-oil supplement as two capsules a day for a month without stating how much hops extract was in each capsule, and found no effect on sleep versus placebo (PMID 20569455). A 2025 trial of a fixed valerian-hops combination extract likewise didn't report its dose in the published abstract, even though it found a modest increase in sleep duration (PMID 40462685). That makes it hard to translate either result into a specific milligram recommendation — a limitation of the available research, not something this page can fill in.
Why the appetite-trial dose may not transfer to a typical capsule
The bitter hop extract used in the appetite trials above is a specific, concentrated preparation, in some cases delivered in delayed-release capsules designed to release lower in the gut. A standard hops or valerian-hops capsule sold for relaxation or sleep support is typically a different kind of preparation — often standardized to a compound like xanthohumol rather than to the bitter acids these trials concentrated — so a milligram number from one doesn't necessarily predict the effect of the other. See how to choose a good hops for what to check on a specific product's label.
Is there a maximum, or a dose that's "too much"?
No government body has set an upper intake level for hops. The highest single dose in a placebo-controlled human trial we found was 500 mg of a concentrated bitter hop extract, and even that dose came with more reports of gastrointestinal discomfort than placebo (PMID 35102364) — a reason not to assume more is simply better. See hops side effects for what's been reported.
Dosing for pets
This page and its citations cover hops as a human dietary supplement. None of the research here was conducted in animals at a dose meant to guide pet use, and hops is not something to give a dog or cat based on a human supplement label. Ask a veterinarian for guidance specific to an animal.
Questions people ask
How much hops extract should I take a day?
There's no single research-backed number. The clearest human data comes from appetite trials using 100-500 mg of a specific, concentrated bitter hop extract; sleep-focused hops products haven't published a comparable dose. Following the directions on a specific product's label, and checking with a pharmacist if you're unsure, is more reliable than a number pulled from this literature.
Is 120 mg of hops extract a meaningful dose?
It sits within the lower end of the range tested in the appetite trials (100-250 mg), though those trials used a specific bitter-acid-concentrated extract, not necessarily the same preparation as a 120 mg capsule sold for relaxation. There's no research showing 120 mg specifically does anything on its own.
What's a high dose of hops extract?
The highest single dose tested in a placebo-controlled human trial we found was 500 mg of a concentrated bitter hop extract. Above that, there's no published trial data to say what a higher amount does.
Is hops extract safe for dogs?
This page covers human dosing research only. Ask a veterinarian before giving hops to a dog.

- An extract of hops (Humulus lupulus L.) modulates gut peptide hormone secretion and reduces energy intake in healthy-weight men: a randomized, crossover clinical trial A 2022 randomized crossover trial found a single 500 mg dose of a bitter hop extract reduced how much food 19 healthy-weight men ate at their next meal, alongside changes in appetite-related gut hormones, though it also caused more gastrointestinal discomfort than placebo and didn't change how hungry people said they felt.
- Gastrointestinal delivery of bitter hop extract reduces appetite and food cravings in healthy adult women undergoing acute fasting A 2024 randomized crossover trial found a bitter hop extract, taken twice during a 24-hour fast, reduced appetite and food cravings in 30 women at both a 125 mg and 250 mg dose, with a few reports of loose stools or heartburn, mostly at the higher dose.
- New Zealand Bitter Hops Extract Reduces Hunger During a 24 h Water Only Fast A 2019 randomized trial found a bitter hop extract reduced hunger ratings by more than 10% during a 24-hour fast in 30 men, at both a 100 mg and 250 mg dose, and blunted the usual midday hunger spike seen with placebo.
- Effects of intraduodenal or intragastric administration of a bitter hop extract (Humulus lupulus L.), on upper gut motility, gut hormone secretion and energy intake in healthy-weight men A 2023 randomized trial found a bitter hop extract produced only modest, transient hormone changes and did not reduce appetite or food intake at a subsequent meal in healthy-weight men, a null result at odds with other trials using a longer fasting protocol.
- A dietary supplement to improve the quality of sleep: a randomized placebo controlled trial A 2010 randomized, placebo-controlled trial found a hops-and-fish-oil supplement produced no significant improvement in sleep quality, sleep efficiency or melatonin levels over placebo in adults with moderate-to-severe chronic insomnia.
- Effects of a Valerian-Hops Extract Combination (Ze 91019) on Sleep Duration and Daytime Cognitive and Psychological Parameters in Occasional Insomnia: A Randomized Controlled Feasibility Trial A 2025 randomized, placebo-controlled trial of a combined valerian-and-hops extract (not hops alone) found a modest increase in nightly sleep duration in 40 adults with occasional sleep problems, with no effect on daytime cognitive or mood measures.
