HelloPharmacist Scorecard of Hops by Nature's Sunshine
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
This product contains one active ingredient: hops, the flowering cone of the hop plant. Hops has a long history in herbal medicine, traditionally used for relaxation and sleep support.
The capsule itself is an inactive ingredient — it's just the delivery form.
Does it work?
Not established
The evidence we have doesn't yet establish whether hops works for any of its common uses. Our data rates the following as insufficient reliable evidence to draw a conclusion: age-related cognitive decline, sexual dysfunction, anxiety, ADHD, dyspepsia (indigestion), and insomnia.
That doesn't mean it doesn't work — it means the research so far isn't strong enough to say either way. If you're considering hops for one of these reasons, talk it over with your doctor or pharmacist about what the current science supports.
How safe is it?
Well-documented data
Hops is generally well tolerated in the short term, but drowsiness is possible. Long-term safety hasn't been well studied, so we don't have solid data on what happens if you take it regularly for months or years.
Occupational exposure to hops dust has been linked to chronic respiratory symptoms like dry cough and bronchitis, though that's mainly a concern for people working with large amounts of the plant dust. The safety data advises against hops during pregnancy.
For breastfeeding, there isn't enough information to know whether it's safe, so it's best avoided until you've talked with your doctor or pharmacist. A few cases of postmenopausal bleeding have been reported in people taking supplements that combined hops with soy, though it's unclear which ingredient — or the combination — caused it.
Meds to double-check
Moderate interaction found
Before taking hops, double-check with your doctor or pharmacist if you're on sedating drugs like sleeping pills or anti-anxiety medications — the risk of additive drowsiness is Moderate. Also mention estrogen-based medications, including hormone replacement therapy and birth control, since hops may interfere with how they work.
If you take drugs that depend on CYP1A2 or CYP3A4 liver enzymes to break down (including many heart and blood pressure medications, statins, and immunosuppressants), confirm it's okay to combine — the interaction is Minor but worth verifying with your provider.
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 is traditionally used for relaxation and sleep, but current evidence doesn't yet confirm whether it works for those or other common uses. If you take sedating medications or hormone replacement therapy, you'll want to check with your doctor or pharmacist before adding hops — the interactions are moderate, and drowsiness is a real possibility.
Pregnant and breastfeeding individuals should avoid it. Run your full medication list through the interaction checker on this page.

Hops by Nature's Sunshine Drug Interactions
HelloPharmacist Interaction Report
Hops by Nature's Sunshine does interact with several medication types.
The most serious concern is with sedating drugs (CNS depressants) — hops has sedative properties, and combining it with sleep aids, anti-anxiety medications, or other sedating drugs could cause additive drowsiness. This is a Moderate severity interaction.
Read the full breakdown — every affected drug type, severity by severity
Hops may also interfere with estrogen-based medications, including hormone replacement therapy. The concern is theoretical — hops constituents can compete for estrogen receptors — but most hops extracts contain very small amounts of these compounds, so the practical risk depends on the dose and formulation you're taking.
Two other drug categories show Minor interactions: medications that depend on CYP1A2 or CYP3A4 liver enzymes for breakdown. While in vitro research suggests hops flavonoids might affect these enzymes, a human study found no clinically significant effect at typical doses.
Because the practical impact is unclear, it's still worth checking your exact medications.
Altogether, these interactions span 864 individual medications. Use the search tool on this page to look up any prescription or over-the-counter drug you take before starting hops.

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