HelloPharmacist Scorecard of Horny Goat Weed with Maca by Herbadiet

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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

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 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains two active ingredients: Maca root extract and Horny Goat Weed Extract. The capsule shell itself is made from vegetable cellulose, which is an inactive ingredient.

Both actives have a long history in herbal medicine, though modern research on them as supplements is still developing.

Does it work?

Insufficient evidence
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
Insufficient

There isn't enough reliable clinical evidence to rate this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: sexual vitality and energy boost.
  • We looked for evidence on: Erectile dysfunction (ED), Sexual desire, Sexual dysfunction, Fatigue, Age-related testosterone deficiency, Antidepressant-induced sexual dysfunction — and 3 related terms.
  • The closest evidence on file: Maca is rated "Insufficient Reliable Evidence To Rate" for Antidepressant-induced sexual dysfunction (Natural Medicines).
  • Also on file: Maca is rated "Insufficient Reliable Evidence To Rate" for Chronic fatigue syndrome (CFS), Fatigue, Sexual desire, Age-related testosterone deficiency.
  • Also on file: Horny Goat Weed is rated "Insufficient Reliable Evidence To Rate" for Sexual dysfunction, Erectile dysfunction (ED).

The evidence for what these ingredients actually do isn't established in our data. Horny Goat Weed Extract has been studied for sexual dysfunction, bronchitis, heart health, and bone health, but the data rates all of these as having insufficient reliable evidence.

Maca root extract shows the same picture across several uses—amenorrhea, anemia, sexual dysfunction from antidepressants, athletic performance, and bone health—all rated as insufficient evidence. That doesn't mean they don't work; it means we don't have enough solid clinical trials yet to say either way.

The evidence, ingredient by ingredient Maca Horny Goat Weed

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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Horny Goat Weed is generally well tolerated when used short-term, though human safety data is limited and quality varies between products. The most common side effects are dizziness, dry mouth, nosebleed, thirst, and vomiting.

One rare serious case of irregular heartbeat was reported in a 66-year-old with heart disease after two weeks of use, but it's unclear whether the product contained only horny goat weed or other ingredients too. Maca root is generally well tolerated as a food, though supplement safety hasn't been studied long-term; if it's fresh and uncooked, it may cause stomach pain.

During pregnancy, horny goat weed is rated possibly unsafe and should be avoided. Maca should also be avoided in pregnancy because there isn't enough safety data.

For breastfeeding, there isn't enough reliable information for either ingredient, so talk with your doctor or pharmacist before using this product if you're nursing.

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 2 matched ingredients can interact with medications — Horny Goat Weed.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 964 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, check if you're on blood thinners or antiplatelet drugs (like warfarin or clopidogrel), blood pressure medications, estrogen or hormone therapy, or any drugs metabolized by CYP1A2, CYP2B6, or CYP3A4 enzymes—all of these are affected at a Moderate level. Use the medication checker on this page with your exact drug names to be sure.

The bottom line

Scorecard at a glanceFully disclosed formula with insufficient evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This product is for anyone curious about traditional herbal support for sexual function and general wellness, but it's not proven to work for any condition in solid clinical trials. If you take blood thinners, blood pressure medication, hormone therapy, or drugs your liver processes through the three main pathways we mentioned, you need to check with your pharmacist first.

If you're pregnant or breastfeeding, skip it. Everyone else should run their medications through the checker before starting.

Horny Goat Weed with Maca by Herbadiet: Common Questions

Does Horny Goat Weed with Maca by Herbadiet interact with any medications?
Yes. Based on its ingredients, Horny Goat Weed with Maca has a known interaction with 963 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Horny Goat Weed with Maca contains 2 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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.
Is this safe to take while I'm pregnant?
No. Horny Goat Weed is rated possibly unsafe in pregnancy and should be avoided. Maca also doesn't have enough safety data in pregnancy, so it should be avoided too. Talk with your doctor before using any supplement if you're pregnant or trying to become pregnant.
Can I take this while breastfeeding?
There isn't enough reliable information on safety for either ingredient while breastfeeding. Talk with your doctor or pharmacist to decide what's right for you and your baby.
What are the most common side effects?
Horny Goat Weed can cause dizziness, dry mouth, nosebleed, thirst, and vomiting, especially with short-term use. Maca may cause stomach pain if it's fresh and uncooked. Most people tolerate both fairly well, but quality varies between products.
Does this actually work for sexual dysfunction?
Both ingredients have been studied for sexual function, but the evidence isn't strong enough yet to say whether they work. We rate both as having insufficient reliable evidence, which means more research is needed.
How long can I safely take this?
Short-term use of horny goat weed is generally tolerated, but long-term safety hasn't been well studied as a supplement. If you use it regularly long-term, you may be more likely to experience side effects like vomiting, dry mouth, thirst, and nosebleed. Talk with your pharmacist about how long is right for you.
What exactly is Maca root extract?
Maca is a root vegetable that's generally well tolerated as a food, though supplement safety hasn't been studied long-term. Fresh, uncooked maca may cause stomach pain. It's been used traditionally for various health purposes, but we don't have strong evidence it works for any specific condition yet.
