HelloPharmacist Scorecard of Estro8PN Hop Extract 10 mg by Swanson Superior Herbs

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: Estro8PN Hop extract at 10 mg per capsule. Hops is a plant used traditionally to support relaxation and sleep.

The extract is delivered in a capsule made of hypromellose with brown rice flour as an inactive filler.

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

This is a single-ingredient Hops product and its label doesn't state a use — see Hops's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The data we hold does not establish that hops extract is effective for the conditions it's marketed for—age-related cognitive decline, sexual dysfunction, anxiety, ADHD, indigestion (dyspepsia), or insomnia. All of these carry an Insufficient Reliable Evidence To Rate rating, meaning the research is too limited or weak to draw a firm conclusion.

If you're considering this for any of these purposes, talk it over with your doctor to explore what evidence exists and what might work better for your situation.

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 extract is generally well tolerated in the short term but may cause drowsiness, and long-term safety hasn't been well studied. The safety data advises against use during pregnancy due to insufficient information.

Breastfeeding safety is unknown, so the data advises against it as well. Occupational exposure to hops dust (usually mixed with other dust) has been linked to chronic cough, shortness of breath, and bronchitis—though that's an industrial-exposure concern, not a typical supplement use.

A small number of reports link supplements containing both hops and soy to postmenopausal bleeding, though it's unclear whether hops, soy, or the combination is responsible. Fresh hops plant contact and pollen can trigger allergic reactions and contact dermatitis in some people.

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 take this product, double-check with your pharmacist if you use sedative drugs (sleeping pills, anxiety medications, or pain relievers with sedating effects)—hops may add to their drowsy effects. If you take estrogen or hormone replacement therapy, confirm it's okay, since hops might interfere.

Additionally, if you take any drugs metabolized by your liver (a very large group), mention this supplement so your pharmacist can verify there's no unexpected interaction.

Check your own medication Run your meds through the checker above

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.

Hops extract is generally well tolerated in the short term for people without sedative use, hormone therapy, or sensitivity to its ingredients. If you take any sedatives or estrogen-based medications, or if you're pregnant or breastfeeding, check with your doctor or pharmacist before starting.

Long-term safety isn't well understood, so this is worth discussing with your own healthcare provider if you plan to use it regularly.

Estro8PN Hop 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.

Estro8PN Hop Extract 10 mg by Swanson Superior Herbs: Common Questions

Does Estro8PN Hop Extract 10 mg by Swanson Superior Herbs interact with any medications?
Yes. Based on its ingredients, Estro8PN Hop Extract 10 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?
Estro8PN Hop Extract 10 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 this make me drowsy?
Hops extract may cause drowsiness, especially in the short term. If you're sensitive to sedating effects or combine it with sleep aids or anxiety medications, drowsiness is more likely. Start low and see how you respond before driving or operating machinery.
Can I take this if I'm on hormone replacement therapy?
The data raises a Moderate-severity concern: hops compounds may compete with estrogen receptors and theoretically interfere with hormone therapy. The amounts in most extracts are small, but you should check with your doctor or pharmacist before combining them.
Is it safe to take long-term?
The safety data only covers short-term use well. Long-term safety hasn't been well studied, so if you plan to take this regularly, talk it over with your doctor or pharmacist to make sure it's right for you.
Can I use this while pregnant or breastfeeding?
No. The data advises against use during pregnancy because there isn't enough safety information. Breastfeeding safety is also unknown, so it's best avoided then too. Talk with your doctor about what's safe if you're planning pregnancy or nursing.
Does this actually help with sleep or anxiety?
The evidence we have is insufficient to say it works for insomnia, anxiety, or any of the other conditions listed. If you're looking for help with sleep or anxiety, your doctor can discuss what options have stronger evidence behind them.
What's the difference between this extract and whole hops?
This is a concentrated extract (10 mg per capsule). The data we hold doesn't compare it directly to whole hops or other forms, so we can't say how potency or effects differ. A pharmacist can help you weigh different hops products if that matters to your choice.
