HelloPharmacist Scorecard of Man Up Power + by Herbal Goodness

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 Aug 20, 2026

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 5 active ingredients.
  • “Extract Blend” is a proprietary blend — the label doesn't break down how much of each component you get.

Man Up Power + contains 5 ingredients, including three active herbal extracts. Horny goat weed extract, nettle extract, and ashwagandha extract are the main active components; the product also includes an extract blend and Jamaican sarsaparilla root extract.

There are no inactive ingredients listed.

Does it work?

Moderate 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
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: support male hormones and sexual vitality.
  • We looked for evidence on: Age-related testosterone deficiency, Erectile dysfunction (ED), Male infertility, Sexual desire, Sexual dysfunction, Fatigue — and 4 related terms.
  • The strongest evidence on file: Ashwagandha is rated "Possibly Effective" for Insomnia (Natural Medicines).
  • Also on file: Ashwagandha is rated "Possibly Effective" for Stress.
  • Also on file: Maca is rated "Insufficient Reliable Evidence To Rate" for Antidepressant-induced sexual dysfunction, Athletic performance, Chronic fatigue syndrome (CFS), Fatigue, and more.

The evidence for this product's ingredients is quite limited. Ashwagandha shows the strongest data — it's rated possibly effective for insomnia, anxiety, stress, and generalized anxiety disorder.

Nettle is rated possibly effective for diabetes support. Horny goat weed, Jamaican sarsaparilla, and maca all lack sufficient reliable evidence for their claimed uses in our data — the research either doesn't exist yet or isn't strong enough to draw conclusions.

The evidence, ingredient by ingredient Horny Goat Weed Stinging Nettle Ashwagandha Maca

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.

Ashwagandha and horny goat weed are generally well tolerated short-term, though quality and long-term safety vary by product. Nettle is also generally well tolerated for most adults.

Common side effects include dizziness, dry mouth, nosebleed, thirst, vomiting (horny goat weed); constipation and diarrhea (nettle); and diarrhea, nausea, vomiting, and gastrointestinal upset (ashwagandha). Rare but serious concerns exist: horny goat weed has been linked to respiratory arrest, and ashwagandha to acute liver failure and hepatitis.

Pregnancy safety data is limited or advises against use — horny goat weed is possibly unsafe and ashwagandha and nettle are likely unsafe during pregnancy. Breastfeeding safety is not established for any of the three main ingredients; avoid use until you've talked with your doctor or pharmacist.

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 3 of the 4 matched ingredients can interact with medications — Stinging Nettle, Horny Goat Weed, Ashwagandha.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications; lithium.
  • For scale: 1,443 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 Man Up Power +, check with your doctor or pharmacist if you take blood pressure medications (antihypertensive drugs), blood thinners (anticoagulants or antiplatelet drugs), diabetes medications, sedatives or anti-anxiety drugs (benzodiazepines or other CNS depressants), thyroid hormone, lithium, warfarin specifically, or any drug that may stress your liver. Horny goat weed also affects how your liver breaks down certain medications (CYP1A2, CYP2B6, and CYP3A4 substrates), potentially raising their levels.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This product may appeal to someone looking for herbal support for sexual function or stress, but the evidence for most ingredients is lacking. If you take any medications — especially blood pressure drugs, diabetes medications, blood thinners, sedatives, thyroid hormone, or anything your liver processes — you need to check your specific medications with your pharmacist or doctor before starting.

Pregnant or breastfeeding individuals should not use this product without guidance from their healthcare provider.

Ashwagandha Extract10 drug types · 1,372 drugs

Antidiabetes Drugs

Theoretically, taking ashwagandha with antidiabetes drugs might increase the risk of hypoglycemia.
There is preliminary clinical evidence suggesting that ashwagandha might lower blood glucose levels. Theoretically, ashwagandha might have additive effects when used with antidiabetes drugs and increase the risk of hypoglycemia.

Likelihood Possible Evidence B
Antihypertensive Drugs

Theoretically, taking ashwagandha with antihypertensive drugs might increase the risk of hypotension.
Animal research suggests that ashwagandha might lower systolic and diastolic blood pressure. Theoretically, ashwagandha might have additive effects when used with antihypertensive drugs and increase the risk of hypotension.

Likelihood Possible Evidence D
Benzodiazepines

Theoretically, taking ashwagandha might increase the sedative effects of benzodiazepines.
There is preliminary evidence that ashwagandha might have an additive effect with diazepam (Valium) and clonazepam (Klonopin). This may also occur with other benzodiazepines.

Likelihood Possible Evidence D
Cns Depressants

Theoretically, taking ashwagandha might increase the sedative effects of CNS depressants.
Ashwagandha seems to have sedative effects. Theoretically, this may potentiate the effects of barbiturates, other sedatives, and anxiolytics.

Likelihood Possible Evidence D
Hepatotoxic Drugs

Theoretically, taking ashwagandha with hepatotoxic drugs might increase the risk of liver damage.
Ashwagandha has been linked to cases of acute hepatitis, liver failure, hepatic encephalopathy, autoimmune hepatitis, the need for liver transplantation, and death due to liver failure.

Likelihood Possible Evidence D
Immunosuppressants

Theoretically, taking ashwagandha might decrease the effects of immunosuppressants.
Ashwagandha has demonstrated immunostimulant effects in humans. Animal research has shown that ashwagandha can attenuate the immunosuppression caused by cyclophosphamide.

Likelihood Possible Evidence D
Thyroid Hormone

Ashwagandha might increase the effects and adverse effects of thyroid hormone.
Concomitant use of ashwagandha with thyroid hormones may cause additive therapeutic and adverse effects. Preliminary clinical research and animal studies suggest that ashwagandha boosts thyroid hormone synthesis and secretion. In one clinical study, ashwagandha increased triiodothyronine (T3) and thyroxine (T4) levels by 41.5% and 19.6%, respectively, and reduced serum TSH levels by 17.4% from baseline in adults with subclinical hypothyroidism.

Likelihood Probable Evidence B
Cytochrome P450 1A2 (Cyp1A2) Substrates

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

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

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

Likelihood Possible Evidence D
Serotonergic Drugs

Some animal studies have reported that ashwagandha can enhance serotonergic transmission by altering certain serotonin (5-HT) receptors. However, there is no evidence to suggest that ashwagandha increases the risk of serotonin-related effects, and there have been no published case reports of serotonin syndrome when combined with other serotonergic drugs. Nevertheless, due to the lack of extensive studies on the matter and the fact that ashwagandha appears to affect serotonergic pathways, it would be prudent to exercise caution when combining it with drugs that affect serotonin.

Anticoagulant/Antiplatelet Drugs

Theoretically, horny goat weed might increase the risk of bleeding.
In vitro research and animal research shows that horny goat weed can inhibit platelet aggregation and thrombus formation. This effect has not been reported in humans.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, horny goat weed might increase the risk of hypotension.
Laboratory research suggests that horny goat weed might have hypotensive effects. This effect has not been reported in humans.

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

Theoretically, horny goat weed might increase the effects and side effects of CYP1A2 substrates.

Theoretically, horny goat weed might increase the effects and side effects of CYP2B6 substrates.
In vitro, horny goat weed leaf extract inhibits CYP2B6. This effect has not been reported in humans.

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

Theoretically, horny goat weed might increase the effects and side effects of CYP3A4 substrates.
In vitro, horny goat weed extract inhibits CYP3A4 and suppresses CYP3A4 mRNA expression. This effect has not been reported in humans.

Likelihood Possible Evidence D
Estrogens

Theoretically, concomitant use of horny goat weed with estrogens might increase their therapeutic and adverse effects.
In vitro evidence suggests that horny goat weed has estrogenic activity. In clinical research, horny goat weed has been shown to increase blood levels of estrogen in some females.

Likelihood Possible Evidence D
Horny Goat Weed extract full monograph & interactions

Nettle extract4 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.

Man Up Power + by Herbal Goodness: Common Questions

Does Man Up Power + by Herbal Goodness interact with any medications?
Yes. Based on its ingredients, Man Up Power + has a known interaction with 1,442 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Man Up Power + contains 5 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 if I'm pregnant or breastfeeding?
No. The safety data advises against use during pregnancy — horny goat weed is possibly unsafe, and ashwagandha and nettle are likely unsafe. Breastfeeding safety has not been established for the main ingredients. Talk with your doctor or pharmacist before considering this product in either situation.
What are the most common side effects?
Dizziness, dry mouth, nosebleed, and thirst (horny goat weed); constipation or diarrhea (nettle); and diarrhea, nausea, vomiting, and stomach upset (ashwagandha). These don't occur with every user, but they're the ones most often reported.
Does this actually work for sexual dysfunction?
Horny goat weed, the main ingredient marketed for this, hasn't been studied enough to say. Our data shows insufficient reliable evidence to rate it for sexual dysfunction. Ashwagandha has better evidence for stress and anxiety, which may indirectly help, but that's not the same thing.
Can I take this if I'm on a blood thinner like warfarin?
Not without checking first with your doctor or pharmacist. Nettle contains vitamin K, which can interfere with warfarin's blood-thinning effects, and horny goat weed may also raise bleeding risk. Your dose or medication choice may need adjustment.
What are the serious side effects I should watch for?
Liver damage (ashwagandha) and respiratory problems (horny goat weed) are rare but serious. If you experience severe abdominal pain, yellowing of skin or eyes, difficulty breathing, or chest pain, stop taking the product and seek medical attention right away.
How long can I safely use this powder?
Short-term use is what the safety data covers. Long-term safety hasn't been well studied for any of these ingredients, and quality varies between products. Talk with your pharmacist or doctor about how long is appropriate for you.
