HelloPharmacist Scorecard of Hops by Herbalist & Alchemist

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.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Aug 6, 2026

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 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This is a straightforward one-ingredient liquid: fresh hops strobile extract — that's the cone from the hops plant that's been extracted and concentrated. The extract is suspended in ethyl alcohol and distilled water.

That's it — no other active ingredients.

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: Promotes restful sleep.
  • We looked for evidence on: Insomnia, Shift work disorder, Anxiety, sleep quality, sleep onset, sleep maintenance.
  • 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, Shift work disorder.

The evidence for hops on the conditions listed here — cognitive decline, sexual dysfunction, anxiety, ADHD, indigestion, and insomnia — is insufficient. That means we don't have solid data yet to say whether it works for any of them.

If you're considering hops for one of these reasons, talk it through with your doctor or pharmacist about what the research actually supports.

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 drowsiness is possible — which makes sense given its sedative properties. Long-term safety hasn't been well studied, so we don't know what happens if you take it for months or years.

Pregnancy and breastfeeding are off-limits: there isn't enough safety information to recommend hops during pregnancy or while nursing. If you're in either situation and interested in hops, check with your doctor or pharmacist.

One more note: occupational exposure to hops dust (common in harvesting) is linked to chronic respiratory issues like cough and bronchitis; orally, there are rare reports of postmenopausal bleeding and menstrual changes, though it's unclear whether hops alone or a combination with other ingredients caused them.

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 you start, double-check with your doctor or pharmacist if you take sedatives or other CNS depressants (sleeping pills, anti-anxiety meds) — hops may deepen drowsiness. Also flag any estrogen-based medications, including hormone replacement therapy.

Medications processed through liver enzymes CYP1A2 and CYP3A4 should be reviewed, though the interaction is likely minor.

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.

Hops may help with certain conditions, but the evidence isn't solid yet. The main cautions are drowsiness, interactions with sedatives and estrogen-based hormones, and the fact that safety in pregnancy and breastfeeding is unknown.

If you take any sedatives, hormone medications, or drugs metabolized by your liver, check with your doctor or pharmacist before adding this to your routine.

fresh Hops strobile 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 by Herbalist & Alchemist: Common Questions

Does Hops by Herbalist & Alchemist interact with any medications?
Yes. Based on its ingredients, Hops 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 contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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?
It may. Hops has sedative effects based on animal research, and drowsiness is a known side effect. Don't drive or operate machinery until you know how it affects you, and definitely avoid it if you're already taking sleeping pills or sedatives.
Is this safe during pregnancy or breastfeeding?
No. There isn't enough safety data for pregnancy, and we don't have enough information about breastfeeding either. Talk with your doctor or pharmacist about alternatives if you're pregnant or nursing.
Can hops help with insomnia or anxiety?
The evidence isn't established yet in our data. While hops does have sedative properties, we don't have solid research showing it actually works for insomnia or anxiety. Your doctor or pharmacist can discuss whether it's worth trying.
What's in this liquid besides the hops?
Just ethyl alcohol and distilled water — they're there to extract and preserve the hops compounds. No fillers or binders.
Can this affect my birth control or hormone therapy?
Possibly. Large amounts of hops might interfere with how estrogen-based medications work, though most hops extracts contain only small amounts of the compounds that do this. Check with your doctor or pharmacist if you take any hormone medications.
Is there anything else I should watch for?
If you harvest or handle fresh hops, be aware that dust and pollen can cause allergic reactions and contact dermatitis. Orally, there are rare reports of postmenopausal bleeding and menstrual changes in people taking hops with other ingredients like soy, though it's not clear what caused it.
