Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 4 of its 4 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Horny Goat Weed Complex contains 4 active ingredients. Maca is a root traditionally used in Peruvian cuisine; mucuna pruriens (also called cowhage) is a tropical plant that naturally contains levodopa, the same compound used in Parkinson's medications; horny goat weed extract comes from an Asian plant; and tribulus terrestris is a spiky-fruited plant used in traditional medicine.

The product also includes inactive ingredients: rice flour, gelatin, maltodextrin, and magnesium stearate, which are fillers and binders that help form and preserve the capsule.

Evidence for Intended Use · database check

Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: supports sexual health for both men and women.
  • We looked for evidence on: Erectile dysfunction (ED), Sexual desire, Sexual dysfunction, Antidepressant-induced sexual dysfunction, Premature ejaculation, Male infertility — and 4 related terms.
  • The strongest evidence on file: Tribulus is rated "Possibly Effective" for Sexual dysfunction (Natural Medicines).
  • Also on file: Tribulus is rated "Insufficient Reliable Evidence To Rate" for Erectile dysfunction (ED), Premature ejaculation, Male infertility.
  • Also on file: Maca is rated "Insufficient Reliable Evidence To Rate" for Antidepressant-induced sexual dysfunction, Sexual desire, Age-related testosterone deficiency.

The evidence supporting these ingredients is limited. For maca, the data we hold shows insufficient evidence to rate it for any condition, including sexual function, amenorrhea, anemia, or bone health.

Mucuna pruriens likewise has insufficient evidence for anxiety, sexual dysfunction, Parkinson's disease, or rheumatoid arthritis. Horny goat weed extract shows insufficient evidence for sexual dysfunction, osteoporosis, bronchitis, or heart disease.

Tribulus terrestris is the only ingredient with a positive rating: it's possibly effective for sexual dysfunction, though it's rated possibly ineffective for athletic performance, and insufficient evidence exists for prostate health. Overall, this product's effectiveness for its intended use is not well established in the data we hold.

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 4 of the 4 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 4 of 4.
  • General safety write-ups exist for 4 of 4.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Mucuna pruriens and horny goat weed extract carry the most cautions. Because mucuna contains levodopa—an active drug-like compound—it should be used only with professional guidance.

Horny goat weed has limited human safety data; short-term tolerability appears reasonable, but quality varies between products. Common side effects from horny goat weed include dizziness, dry mouth, nosebleed, thirst, and vomiting; one rare report noted respiratory arrest.

Mucuna pruriens may cause diarrhea, flatulence, dry mouth, nausea, abdominal bloating, vomiting, headaches, and in about 3% of users taking high doses, insomnia. Tribulus is generally well tolerated short-term but can cause abdominal pain, cramping, nausea, vomiting, diarrhea, or constipation; rarely, liver and kidney injury, seizures, or priapism (chronic painful erection) have been reported.

Maca may cause stomach pain if consumed raw or uncooked, though it's generally well tolerated as a food; long-term supplement safety has not been studied.

Why this rating?
  • 3 of the 4 matched ingredients can interact with medications — Tribulus, Horny Goat Weed, Cowhage.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications; lithium; Parkinson's medications.
  • For scale: 1,117 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 taking this product, check with your pharmacist or doctor if you take any monoamine oxidase inhibitors (MAOIs), methyldopa or other blood pressure medications, levodopa, diabetes medications, antipsychotic drugs, tricyclic antidepressants, lithium, or blood thinners (anticoagulants). Additionally, let them know if you're scheduled for surgery requiring anesthesia, or if you take estrogen-based medications or drugs processed through the liver (CYP1A2, CYP2B6, or CYP3A4 substrates).

No interactions are documented in our data for any ingredient we could not fully check; however, absence of documented interactions is not a guarantee none exist.

The bottom line

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

This product combines four botanical ingredients with limited effectiveness evidence and multiple medication interactions you'll need to check first. If you take blood pressure drugs, diabetes medications, MAOIs, levodopa, blood thinners, estrogen, antipsychotics, or lithium, talk with your pharmacist or doctor before starting—the interactions can be serious.

Even without those, clear this with your own healthcare provider, especially if you're taking any prescription medication at all.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, concomitant use of cowhage and antidiabetes drugs might increase the risk of hypoglycemia.
Animal research shows that cowhage might have hypoglycemic effects.

Likelihood Possible Evidence D
Antipsychotic Drugs

Theoretically, use of cowhage might decrease the clinical effects of antipsychotic drugs.
Cowhage contains levodopa. Use of levodopa might counteract the antidopaminergic effects of antipsychotic medications.

Likelihood Possible Evidence D
Guanethidine (Ismelin)

Theoretically, concomitant use of cowhage and guanethidine might increase the risk of hypotension.
Cowhage contains levodopa. Use of levodopa with guanethidine might cause additive hypotension; avoid using.

Likelihood Probable Evidence D
Tricyclic Antidepressants (Tcas)

Theoretically, use of TCAs might reduce the levels and clinical effects of cowhage.
Cowhage contains levodopa. Use of TCAs might reduce the absorption of levodopa. Some case reports describe patients that developed hypertension and dyskinesia when taking both levodopa and TCAs.

Horny Goat Weed Complex by Swanson: Common Questions

Does Horny Goat Weed Complex by Swanson interact with any medications?
Yes. Based on its ingredients, Horny Goat Weed Complex has a known interaction with 1,116 medications, including 17 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Horny Goat Weed Complex contains 4 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.
Can I take this while pregnant or breastfeeding?
The safety data advises against horny goat weed extract and tribulus terrestris during pregnancy—they're rated possibly unsafe. Mucuna pruriens is rated unsafe in pregnancy because of its dopamine effects and lack of safety data; additionally, L-dopa can lower prolactin and reduce milk supply, so it's unsafe while breastfeeding. Maca also lacks enough safety data in supplement amounts to recommend it during pregnancy, and there's insufficient information for breastfeeding. Talk with your doctor or pharmacist for personalized advice before using this product if you're pregnant or nursing.
What is mucuna pruriens, and why is it in here?
Mucuna pruriens, also called cowhage, is a tropical plant that naturally contains levodopa—the same active compound used in Parkinson's disease medications. It's included in this product for its traditional use, though the evidence supporting it for sexual function or other conditions is insufficient. Because it contains a drug-like compound, it should be used only with professional guidance.
Does this supplement actually improve sexual function?
Tribulus terrestris in this formula is rated possibly effective for sexual dysfunction based on available evidence. However, maca, mucuna pruriens, and horny goat weed extract all show insufficient evidence to rate them for sexual dysfunction. So while one ingredient has some support, the overall effectiveness of this combination is not well established.
What are the most common side effects I might experience?
Horny goat weed may cause dizziness, dry mouth, nosebleed, thirst, or vomiting. Mucuna pruriens can cause diarrhea, flatulence, dry mouth, or nausea, especially at higher doses. Tribulus may cause abdominal pain, cramping, nausea, vomiting, diarrhea, or constipation, though in one study these rates matched those of placebo. Maca may cause stomach pain if the root is fresh or uncooked.
Is this product the same from one brand to another?
No. Quality and potency vary between products because these are botanical supplements without strict standardization. Horny goat weed extract potency and purity especially vary by product, so you can't assume all formulas are equivalent.
Can this interact with my blood pressure or diabetes medications?
Yes. Multiple ingredients in this product may lower blood pressure (horny goat weed, tribulus terrestris) or blood sugar (mucuna pruriens, tribulus terrestris), so combining them with blood pressure or diabetes drugs increases the risk of hypotension or low blood sugar (hypoglycemia). Check with your pharmacist or doctor before starting, as your medication doses may need adjustment.
