HelloPharmacist Scorecard of Hops Science by ResVitale
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
ResVitale Hops Science contains one active ingredient: Perluxan proprietary hops extract. Hops is a plant traditionally used to support relaxation and sleep, though how well it works for these purposes in humans isn't firmly established yet.
The capsule also contains inactive ingredients: a vegetarian capsule shell, rice bran, and silica (a flow agent).
Does it work?
Couldn't assess
The evidence we hold shows insufficient reliable data to rate hops extract for age-related cognitive decline, sexual dysfunction, anxiety, ADHD, indigestion (dyspepsia), or insomnia. That means studies haven't yet established whether it works for these purposes — it's not that we know it doesn't work, just that the case hasn't been made in the research we have on file.
How safe is it?
Well-documented data
Hops extract is generally well tolerated in the short term but may cause drowsiness — so avoid driving or operating machinery until you know how it affects you. The safety notes advise against use during pregnancy because there isn't enough safety information.
While breastfeeding, safety is also unknown, so it's best avoided then too. People exposed to hops dust occupationally have reported chronic respiratory symptoms like cough and shortness of breath.
Some postmenopausal women taking supplements containing both hops and soy have experienced abnormal bleeding, though it's unclear whether hops, soy, or the combination caused it. Allergic reactions and contact rash have been reported from touching fresh hops plants and pollen.
Meds to double-check
Moderate interaction found
Check with your doctor or pharmacist before combining this with sedatives, sleep aids, or anti-anxiety medications — hops may increase drowsiness. If you take any form of estrogen or hormone replacement therapy, mention this supplement, as hops may interfere.
Additionally, if you take medications processed by your liver (a very broad group), ask whether a hops extract might affect how your body handles them.
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.
This is a single-ingredient hops supplement with limited established evidence for its claimed uses. It's generally well tolerated short-term, but it may make you drowsy and shouldn't be taken during pregnancy or while breastfeeding.
Before starting, check your medications — especially sedatives and hormone therapies — with your doctor or pharmacist, since hops can amplify sedation and theoretically interfere with estrogen replacement.

Hops Science by ResVitale Drug Interactions
HelloPharmacist Interaction Report
ResVitale Hops Science contains a hops extract that interacts with three main medication categories.
The most serious concern is with CNS depressants (sedatives, sleep aids, anxiety medications) — hops may add to their sedating effect, potentially increasing drowsiness or impairing alertness.
Read the full breakdown — every affected drug type, severity by severity
Hops also theoretically interferes with estrogens, including hormone replacement therapy, because certain hops compounds can compete for the same receptor sites. Most commercial hops extracts contain only small amounts of these active constituents, but if you take estrogen-based medications, this is worth discussing with your doctor or pharmacist.
Two additional drug categories show minor interactions: hops may alter how your body metabolizes CYP1A2 and CYP3A4 substrates (a large group of medications), though human studies suggest the effect may not be clinically meaningful. Altogether, these interactions span 864 individual medications.

For each ingredient in Hops Science with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.
Perluxan(R) Proprietary Hops Extract
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.
