HelloPharmacist Scorecard of Hops Max-V by Douglas Laboratories

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Hops Max-V contains 2 active ingredients: Hops Female Strobiles Herbal Extract and Hops. The product also includes inactive ingredients — cellulose, silica, and vegetable stearate — which are binding and filling agents in the capsule.

Does it work?

Not established
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Hops's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: sleep and relaxation support.
  • We looked for evidence on: Insomnia, Anxiety, restlessness, nervous tension.
  • The closest evidence on file: Hops is rated "Insufficient Reliable Evidence To Rate" for Anxiety (Natural Medicines).
  • Also on file: Hops is rated "Insufficient Reliable Evidence To Rate" for Insomnia.

The evidence we hold doesn't establish that hops works for any of the conditions this product may be marketed for — age-related cognitive decline, sexual dysfunction, anxiety, ADHD, indigestion (dyspepsia), or insomnia. All of these have insufficient reliable evidence to rate in our data.

The evidence, ingredient by ingredient Hops

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Hops is generally well tolerated in the short term but may cause drowsiness, and long-term safety hasn't been well studied. The data advises against using it during pregnancy because there isn't enough safety information.

Breastfeeding isn't recommended due to unknown safety. Menstrual changes have been reported in women, and a small number of cases of postmenopausal bleeding were linked to supplements containing both hops and soy — though it's unclear whether hops, soy, or the combination was responsible.

Side effects, ingredient by ingredient Hops

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Hops.
  • The most serious interaction on file is rated Moderate.
  • For scale: 864 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking Hops Max-V, double-check with your doctor or pharmacist if you're on sedatives, anti-anxiety medications, or any central nervous system depressants — this product may add to their effect. Also flag it if you're using hormone replacement therapy or estrogen-containing birth control, and if you take medications processed through your liver, like certain statins or blood pressure drugs, because hops may affect how your body handles them.

Check your own medication Run your meds through the checker above

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

This product may appeal to someone looking for herbal support for sleep or anxiety, but the evidence for those uses is thin. If you take sedatives, use hormone replacement therapy or estrogen-based birth control, or take medications metabolized through the liver, you'll want to check your specific drugs with your doctor or pharmacist before starting.

Long-term safety data is limited, and drowsiness is a real possibility.

Hops Female Strobiles Herbal Extract4 drug types · 863 drugs

Cns Depressants

Theoretically, concomitant use of hops with sedative drugs might cause additive sedation.
Some animal research shows that hops has sedative effects.

Likelihood Possible Evidence D
Estrogens

Theoretically, concomitant use of large amounts of hops might interfere with hormone replacement therapy due to competition for estrogen receptors.
In vitro research suggests that certain hops constituents can competitively bind to estrogen receptors. However, most hops extracts contain very small amounts of these constituents.

Likelihood Possible Evidence D
Cytochrome P450 1A2 (Cyp1A2) Substrates

Hops extract does not seem to affect the metabolism of CYP1A2 substrates.
In vitro research suggests that flavonoid constituents of hops inhibit CYP1A2 enzyme activity. However, a pharmacokinetic study in healthy postmenopausal patients shows that taking a standardized extract of spent hops containing prenylated phenols, as 59.5 mg twice daily for 2 weeks, does not affect levels of caffeine, a CYP1A2 probe substrate.

Likelihood Unlikely Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, hops extract might alter metabolism of CYP3A4 substrates; however, this effect may not be clinically significant.
Animal research suggests that specific constituents of hops, called lupulones, can induce hepatic CYP3A4 enzyme activity. However, a pharmacokinetic study in healthy postmenopausal patients with normal metabolism shows that taking a standardized extract of spent hops containing prenylated phenols, as 59.5 mg twice daily for 2 weeks, decreases the concentration of alprazolam, a CYP3A4 probe substrate, by 7.6%. This reduction is unlikely to be clinically relevant.

Hops Max-V by Douglas Laboratories: Common Questions

Does Hops Max-V by Douglas Laboratories interact with any medications?
Yes. Based on its ingredients, Hops Max-V has a known interaction with 863 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Hops Max-V contains 2 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Will this make me drowsy?
Yes, drowsiness is a known side effect of hops. If you're driving or operating equipment, be cautious, especially when you first start taking it.
Is it safe to use during pregnancy?
No — the safety data advises against using hops during pregnancy because there isn't enough information. Talk with your doctor or pharmacist if you're pregnant or planning to become pregnant.
Can I take this while breastfeeding?
The safety data advises against it. There isn't enough information about hops safety during breastfeeding, so discuss it with your doctor or pharmacist first.
Does hops actually work for insomnia or anxiety?
The evidence we hold doesn't establish that it does. Both insomnia and anxiety are rated insufficient reliable evidence to rate — meaning we don't have solid proof either way.
What are the inactive ingredients?
The capsule contains cellulose, silica, and vegetable stearate — all common binding and filling agents.
