Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 3 of its 3 active ingredients.
  • “Stinging Nettle” is listed as a grouped ingredient — the label gives one combined amount (400 mg) without saying how much of each component you get.
  • “Yohimbe” is listed as a grouped ingredient — the label gives one combined amount (750 mg) without saying how much of each component you get.
  • “Avena sativa” is listed as a grouped ingredient — the label gives one combined amount (180 mg) without saying how much of each component you get.

This product contains 3 active ingredients: a yohimbe extract (standardized to 10:1 concentration), an oat extract (4:1 concentration), and a stinging nettle extract (4:1 concentration). Yohimbe is included for its stimulant effects, oats for their potential heart and cholesterol benefits, and stinging nettle for its traditional use in supporting overall wellness.

The remaining ingredients are inactive — fillers and binders like microcrystalline cellulose, dicalcium phosphate, and silica that help form and stabilize the tablet.

Does it work?

Not established
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
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use.

Why this rating?
  • The label markets this product for: support male function.
  • We looked for evidence on: Erectile dysfunction (ED), Benign prostatic hyperplasia (BPH), Sexual performance, Low libido.
  • The closest evidence on file: Stinging Nettle is rated "Insufficient Reliable Evidence To Rate" for Benign prostatic hyperplasia (BPH) (Natural Medicines).
  • Also on file: Yohimbe is rated "Insufficient Reliable Evidence To Rate" for Erectile dysfunction (ED).

The evidence for what this product actually does is limited. Yohimbe has insufficient reliable evidence to support its use for obesity, low blood pressure on standing (orthostatic hypotension), or sexual side effects from antidepressants.

The oat extract is likely effective for lowering cholesterol and supporting heart health, based on clinical evidence. Stinging nettle shows possibly effective evidence for blood sugar control in diabetes but insufficient evidence for allergies, anemia, asthma, prostate health, or gum inflammation.

So while the oat component has solid support, the yohimbe claims lack strong evidence, and stinging nettle's benefits beyond blood sugar are not well established in the data we hold.

The evidence, ingredient by ingredient Stinging Nettle Yohimbe Oats

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 3 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Yohimbe carries serious cautions. It can cause dangerous heart and blood pressure effects, and because supplement potency is unpredictable, the risk is hard to predict.

Common side effects from yohimbine — the active compound — include anxiety, agitation, sweating, diarrhea, flushing, headache, high blood pressure, increased urination, nausea, rapid heart rate, tremors, dizziness, and vomiting. Rare but serious effects include hypertensive crisis (severely high blood pressure requiring emergency care), heart rhythm problems, fluid retention, and chest discomfort.

Yohimbe is unsafe in pregnancy and should be avoided while breastfeeding. Oats in food form are generally well tolerated and considered safe in pregnancy and while breastfeeding, though concentrated oat supplements are less studied.

Common side effects are bloating, gas, and abdominal distention — usually manageable by increasing your dose slowly. Stinging nettle is generally well tolerated but is best avoided in pregnancy and during breastfeeding due to insufficient safety data.

It can cause constipation or diarrhea, and rare cases of liver injury have been reported.

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 3 of the 3 matched ingredients can interact with medications — Stinging Nettle, Yohimbe, Oats.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications; lithium.
  • For scale: 1,205 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, talk with your pharmacist if you take monoamine oxidase inhibitors (MAOIs) for depression — this is a Major-severity interaction. Also check with them if you're on blood pressure medications, heart drugs, stimulants, tricyclic antidepressants, antipsychotics, diabetes medications, insulin, diuretics, lithium, or blood thinners like warfarin.

Additionally, tell your pharmacist about any medications metabolized by liver enzymes (CYP2D6 or CYP3A4), as yohimbe may slow how your body clears them.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Major medication interactions have been identified, and safety information is well characterized.

Consider this product only if you don't take any heart, blood pressure, mood, diabetes, or stimulant medications — and even then, yohimbe's unpredictable strength and serious side effects make it a high-risk choice. If you take any prescription drugs, especially for heart, blood pressure, mood, or blood sugar, talk with your pharmacist or doctor before starting.

Pregnant or breastfeeding? Skip the yohimbe entirely.

The oat and nettle components are generally safer, but this product's yohimbe content makes it a caution overall.

Yohimbe13 drug types · 1,125 drugs

Monoamine Oxidase Inhibitors (Maois)

Concomitant use of MAOIs with yohimbe can result in additive effects.
Yohimbine, a constituent of yohimbe, has MAO inhibitory effects. At high doses, yohimbine is a non-selective inhibitor of MAO.

Likelihood Likely Evidence D
Antihypertensive Drugs

Theoretically, yohimbe might reduce the effects of antihypertensive drugs.
Yohimbine, a constituent of yohimbe, is an alpha-2 adrenoceptor antagonist and has been reported to increase blood pressure in clinical research. Theoretically, concomitant use of yohimbe and antihypertensive drugs can interfere with blood pressure control.

Likelihood Probable Evidence D
Clonidine (Catapres)

Theoretically, yohimbe might precipitate clonidine withdrawal.
Chronic clonidine use can downregulate alpha-2 adrenoreceptors. Animal research and one human case report suggest that concomitant administration of yohimbine, an alpha-2 adrenoceptor antagonist, may precipitate clonidine withdrawal and lead to sympathomimetic toxicity, including hypertensive crisis.

Likelihood Possible Evidence D
Cytochrome P450 2D6 (Cyp2D6) Inhibitors

CYP2D6 inhibitors may increase the levels and adverse effects of yohimbine, a constituent of yohimbe.
In vitro and clinical research shows that the yohimbe bark constituent, yohimbine, is metabolized by CYP2D6 isoenzymes. Paroxetine, a cytochrome P450 (CYP) 2D6 inhibitor, increases the maximum serum concentration of yohimbine and reduces the clearance of yohimbine compared to yohimbine alone in patients who are extensive CYP2D6 metabolizers..

Likelihood Probable Evidence B
Cytochrome P450 2D6 (Cyp2D6) Substrates

Theoretically, yohimbe might increase the levels and adverse effects of CYP2D6 substrates.
In vitro research suggests that yohimbine, a constituent of yohimbe bark, inhibits CYP2D6 enzyme activity.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Inhibitors

Theoretically, CYP3A4 inhibitors might increase the levels and adverse effects of yohimbine, a constituent of yohimbe bark.
In vitro and clinical research shows that the yohimbe bark constituent, yohimbine, is metabolized by CYP3A4 enzymes. Theoretically, drugs that inhibit CYP3A4 might increase the levels and adverse effects of yohimbine.

Likelihood Possible Evidence D
Paroxetine (Paxil)

Paroxetine decreases the clearance of yohimbine and may increase its effects.
Paroxetine, a cytochrome P450 (CYP) 2D6 inhibitor, increases the maximum serum concentration of yohimbine by about 350% and reduces the clearance of yohimbine by about 80% compared to yohimbine alone in patients who are extensive CYP2D6 metabolizers. No significant changes in pharmacokinetic parameters of yohimbine were observed with coadministration of paroxetine in patients who are poor CYP2D6 metabolizers.

Likelihood Probable Evidence B
Phenothiazines

Theoretically, using yohimbine with phenothiazines might have additive effects.
Yohimbine, a constituent of yohimbe, has alpha-2 adrenergic antagonist effects. Theoretically, combining it with phenothiazines can cause additive alpha-2 adrenergic antagonism.

Likelihood Possible Evidence D
Stimulant Drugs

Theoretically, taking yohimbe with stimulant drugs can have additive effects.
Yohimbine, a constituent of yohimbe, has sympathomimetic effects and increases blood pressure in a dose-dependent manner. Theoretically, taking yohimbe with stimulant drugs can have additive stimulant and hypertensive effects.

Likelihood Possible Evidence D
Tricyclic Antidepressants (Tcas)

Theoretically, taking yohimbe with TCAs can increase adverse effects.
A small clinical study in patients taking TCAs for at least 4 weeks shows that receiving doses of intravenous yohimbine 2.5-20 mg daily for up to 7 days precipitates severe anxiety, agitation, and tremor. The effects of yohimbe bark itself are unclear; oral yohimbe bark contains 0.6% to 1.38% yohimbine, but it is unclear how much is absorbed.

Likelihood Possible Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, combining yohimbe bark with antiplatelet or anticoagulant drugs might have additive effects; however, this has not been reported in clinical research.
Research in healthy adults shows that taking yohimbine, a constituent of yohimbe bark, in doses of 8 mg or more, seems to inhibit platelet aggregation in vitro by binding to the alpha-2 adrenoceptor. The effects of yohimbe bark itself are unclear; yohimbe bark contains 0.6% to 1.38% yohimbine, but it is unclear how much is absorbed.

Likelihood Possible Evidence D
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, yohimbe might decrease the levels and clinical effects of CYP1A2 substrates.
In vitro research shows that yohimbe extract induces CYP1A2 enzymes.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, yohimbe might decrease the levels and clinical effects of CYP3A4 substrates.
In vitro research shows that yohimbe extract induces CYP3A4 enzymes.

Likelihood Possible Evidence D
Yohimbe full monograph & interactions

Stinging Nettle4 drug types · 164 drugs

Antidiabetes Drugs

Theoretically, stinging nettle might have additive effects with antidiabetes drugs.
Clinical research shows that stinging nettle might decrease blood glucose levels in patients with diabetes.

Likelihood Possible Evidence B
Diuretic Drugs

Theoretically, combining stinging nettle with diuretic drugs may have additive effects.
Animal research suggests that the above ground parts and roots of stinging nettle may have a diuretic effect.

Likelihood Possible Evidence D
Lithium

Theoretically, stinging nettle might reduce excretion and increase levels of lithium.
Animal research suggests that stinging nettle has diuretic and natriuretic properties, which could alter the excretion of lithium. The dose of lithium might need to be decreased.

Likelihood Possible Evidence D
Warfarin (Coumadin)

There is some concern that stinging nettle might decrease the effects of anticoagulant drugs such as warfarin.
Stinging nettle contains a significant amount of vitamin K. When taken in large quantities, this might interfere with the activity of warfarin.

Likelihood Possible Evidence D
Stinging Nettle full monograph & interactions

Avena sativa2 drug types · 86 drugs

Antidiabetes Drugs

Theoretically, oats may have additive effects with antidiabetic agents and might increase the risk of hypoglycemia.
Consuming oats can decrease blood glucose in patients with diabetes. In those who require insulin, taking oats 100 grams daily for 2 days reduces the insulin dose required to achieve metabolic control.

Likelihood Possible Evidence D
Insulin

Concomitant use of oats and insulin might increase the risk of hypoglycemia.
In patients with insulin-dependent type 2 diabetes, taking oats 100 grams daily for 2 days reduces the insulin dose required to achieve metabolic control.

Yohimbe 750 mg with Avena Sativa by herbscience: Common Questions

Does Yohimbe 750 mg with Avena Sativa by herbscience interact with any medications?
Yes. Based on its ingredients, Yohimbe 750 mg with Avena Sativa has a known interaction with 1,204 medications, including 9 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Yohimbe 750 mg with Avena Sativa contains 3 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.
Does yohimbe really work for sexual performance or weight loss?
According to the evidence available, there isn't enough reliable data to say yohimbe works for sexual side effects from antidepressants, weight loss, or low blood pressure on standing. The research just isn't there yet. That's why we rate it 'insufficient reliable evidence' for those uses.
What are the most common side effects I might notice?
Yohimbine can cause anxiety, agitation, sweating, tremors, nausea, diarrhea, headache, dizziness, and rapid heart rate. The oats may cause bloating and gas, especially when you first start. These tend to be dose-related — starting low and increasing slowly may help.
Is it safe to take this while pregnant or breastfeeding?
No. Yohimbe is unsafe in pregnancy and should be avoided while breastfeeding because safety hasn't been established. The oat and nettle extracts are less clear, but given the yohimbe content, this product isn't recommended for either.
Why does the interaction list mention so many blood pressure and heart drugs?
Yohimbine raises blood pressure in a dose-dependent way and has stimulant effects. It can work against blood pressure meds, add to the effects of stimulants, and trigger dangerous heart rhythms or blood pressure spikes, especially in combination with certain cardiac or psychiatric medications.
What's the difference between yohimbe and yohimbine?
Yohimbine is the active chemical compound found in yohimbe bark. When you take yohimbe, you're getting yohimbine — but the amount varies unpredictably from product to product, which makes side effects and interactions harder to predict.
Is the oat extract in this product the same as eating oatmeal?
No — this is a 4:1 concentrate, so it's much more potent than regular oatmeal. Food oats are safe in pregnancy and while breastfeeding, but concentrated oat supplements are less studied. However, the main concern with this product is the yohimbe, not the oat.
