HelloPharmacist Scorecard of Hops 340 mg by Solaray

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

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 product contains one active ingredient: hops, 340 mg per capsule. Hops is the flowering part of a plant in the beer family, used here as a dietary supplement.

The capsule also contains inactive ingredients — cellulose, rice extract blend, and silica — which are fillers and binding agents.

Does it work?

Couldn't assess
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 assessable

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: herbal support.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

The evidence we hold doesn't establish that hops works for any of these uses. The effectiveness rating for anxiety, insomnia, cognitive decline, sexual function, ADHD, and indigestion is all the same: insufficient reliable evidence.

That doesn't mean it doesn't work — it means the studies so far aren't solid enough for us to say either way.

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 for short-term use but may cause drowsiness, and we don't have much data on what happens if you take it long-term. The main concern is during pregnancy — there isn't enough safety information, so it's best avoided.

Breastfeeding safety is also unknown, so it's not recommended while nursing. Some people have had allergic skin reactions after touching fresh hops plants, though that's less likely from a supplement capsule.

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.

Check with us before using this if you take sedative or sleep medications, hormone replacement therapy, or any drug processed by your liver — including blood pressure pills, heart medications, cancer drugs, or antidepressants. No interactions are documented for the CYP1A2 and CYP3A4 enzyme systems at typical doses, but the potential exists.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

If you're looking to try hops for sleep or anxiety, understand that the evidence doesn't yet support its use for these. Anyone on sedatives or hormone therapy should check with us first.

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 340 mg by Solaray: Common Questions

Does Hops 340 mg by Solaray interact with any medications?
Yes. Based on its ingredients, Hops 340 mg 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 340 mg 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 hops make me drowsy?
It may — hops can cause drowsiness as a side effect, and it can add to the effect of other drugs that make you sleepy. If you drive or need to stay alert, be cautious when you first try it.
Is hops safe during pregnancy?
No, there isn't enough safety data. The facts advise against using hops while pregnant. Talk to your doctor or pharmacist about what's safe for you.
Can I take hops while breastfeeding?
Safety isn't known, so it's not recommended while breastfeeding. There isn't enough data to know if it passes into breast milk or what effects it might have. Check with your pharmacist for personalized advice.
Does hops actually work for sleep or anxiety?
The evidence isn't established yet. Our data shows insufficient reliable evidence for hops to treat insomnia, anxiety, or any of the other uses listed. You might try it, but we can't say it'll work based on current research.
What's in this capsule besides hops?
The capsule contains cellulose, rice extract blend, and silica — all inactive fillers and binders that hold the supplement together. The active ingredient is hops alone.
