Yohimbe: Uses, Benefits, Dosage & Safety
Last updated: June 2026 · Reviewed by the FactoWiki Editorial Team for clarity and source accuracy
Quick summary
Yohimbe is a West African tree bark containing yohimbine, a genuinely active compound studied for erectile dysfunction and fat loss. It is also the most safety-concerning ingredient in this category, with real cardiovascular risks.
What is Yohimbe?
Yohimbe is the bark of an African tree (Pausinystalia johimbe) containing the alkaloid yohimbine. Unlike most herbal aphrodisiacs, yohimbine is pharmacologically active — a prescription form has been used for erectile dysfunction — but over-the-counter yohimbe products vary wildly and unpredictably in their yohimbine content.
What Yohimbe is commonly used for
In supplements, Yohimbe is most often included for men's vitality support. It is used as nutritional support, not as a treatment for any medical condition — the distinction matters, because the claims on a sales page are often stronger than the evidence allows.
How Yohimbe works
Yohimbine blocks alpha-2 adrenergic receptors, which increases noradrenaline, raises blood pressure and heart rate, and can improve blood flow relevant to erections and mobilise fat. These same actions are why it carries genuine cardiovascular and anxiety risks.
What the evidence says
Here's an honest snapshot of what published research suggests about Yohimbe — including where the evidence is limited.
- Prescription yohimbine has reasonable evidence for erectile dysfunction, and some evidence for modest fat loss in lean, active people. (PubMed research)
- Over-the-counter yohimbe bark products are poorly standardised, making both effects and risks unpredictable. (PubMed research)
Typical dosage used in studies
Research with standardised yohimbine uses carefully controlled milligram doses; uncontrolled yohimbe bark supplements make safe dosing difficult. This is research information for context, not a recommendation — confirm what's appropriate for you with a healthcare professional.
Side effects and safety
Yohimbe can cause anxiety, rapid heart rate, high blood pressure, insomnia and, at higher doses, dangerous cardiovascular effects. It is among the riskier supplement ingredients and is banned or restricted in several countries.
Medication interactions and who should avoid Yohimbe
Medication & safety check
It should be avoided by anyone with heart disease, high blood pressure, anxiety disorders or kidney disease, and must not be combined with stimulants, MAOIs, or many antidepressants and blood-pressure drugs. Seek medical advice before any use.
This is general information, not personal medical advice. If you take any medication, confirm it's safe to combine with Yohimbe with your doctor or pharmacist first.

Frequently asked questions
Does yohimbe work for ED?
Prescription yohimbine has reasonable evidence; over-the-counter yohimbe is unpredictable in dose and effect.
Is yohimbe dangerous?
It can be — it raises heart rate and blood pressure and has real cardiovascular risks, unlike most herbal aphrodisiacs.
Does yohimbine burn fat?
It may help modest fat loss in lean, active people, but the safety trade-off is significant.
Who must avoid yohimbe?
Anyone with heart disease, high blood pressure, anxiety, or on stimulants, MAOIs or many antidepressants.
Why do products vary so much?
Bark supplements are poorly standardised, so yohimbine content — and risk — is inconsistent.
