HelloPharmacist Scorecard of Hops Extract by Earthborn Elements
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 Extract (Humulus lupulus). It's a single-ingredient supplement in capsule form, with gelatin as an inactive ingredient to make up the capsule shell.
Does it work?
Couldn't assess
The evidence for hops extract's effectiveness isn't established in our data. We hold insufficient reliable evidence to rate it for age-related cognitive decline, sexual dysfunction, anxiety, ADHD, indigestion, or insomnia — the conditions it's sometimes used for.
That doesn't mean it doesn't work; it means rigorous studies backing those uses either aren't available or aren't strong enough to draw firm conclusions.
How safe is it?
Well-documented data
Hops extract is generally well tolerated short-term, but drowsiness is possible — especially if you're also taking other sedating medications or supplements. The long-term safety picture isn't well studied, so we don't have a clear picture of what happens with extended use.
The safety data advises against use during pregnancy and while breastfeeding, since there isn't enough information to know it's safe in those situations.
Meds to double-check
Moderate interaction found
Before you start, double-check your medications if you take any sedative drugs — sleep aids, anti-anxiety medications, or other CNS depressants carry a Moderate interaction risk. If you use estrogen therapy or hormone replacement, flag that too.
Drugs processed through your liver's CYP1A2 or CYP3A4 pathways have Minor documented interactions, so it's worth a quick cross-check.
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 may be worth considering if you're exploring it for sleep or anxiety, but the evidence supporting those uses isn't strong yet. If you take sedative medications, hormone replacement therapy, or drugs processed through your liver, check with us or your pharmacist first — the interactions are real.
Talk to your pharmacist about whether this fits your medications and health picture.

Hops Extract by Earthborn Elements Drug Interactions
HelloPharmacist Interaction Report
Hops Extract by Earthborn Elements does have documented interactions with medications.
The most serious concern is with sedative drugs (CNS depressants) — hops itself has sedative effects in animal studies, so taking it alongside sleep aids, anti-anxiety medications, or other sedatives might add up to more drowsiness than you'd get from either one alone. This is a Moderate severity interaction.
Read the full breakdown — every affected drug type, severity by severity
Hops also carries a Moderate interaction with estrogens, including hormone replacement therapy. Lab research suggests that certain hops compounds can bind to the same receptors estrogens do, potentially interfering with hormone therapy — though most hops extracts contain only small amounts of these compounds, so the real-world risk is less clear.
Two additional drug types have Minor interactions documented: drugs processed through your liver's CYP1A2 and CYP3A4 pathways. Lab work suggested hops might affect these, but human studies haven't found a clinically meaningful effect — meaning it probably won't matter in practice.
Altogether, these interactions span 853 individual medications.

For each ingredient in Hops Extract 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.
Humulus lupulus
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.
