HelloPharmacist Scorecard of Forza by Totally Products

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.

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 9 of its 9 active ingredients.
  • “Horny Goat Weed, Powder” is listed as a grouped ingredient — the label gives one combined amount (1,000 mg) without saying how much of each component you get.

Forza contains 9 active ingredients. The main ones we have data on are Saw Palmetto berry powder, Macuna Pruriens seed extract (also called cowhage, a source of the compound levodopa), Tongkat Ali powder, Maca powder, and Muira Puama powder.

You'll also find Panax ginseng, Arginine, Icariin, and Polypodium vulgare. The product also contains inactive ingredients — rice flour, gelatin, and magnesium stearate — which serve as fillers and capsule material.

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: Male sexual function and energy support.
  • We looked for evidence on: Erectile dysfunction (ED), Sexual desire, Sexual dysfunction, Age-related testosterone deficiency, Male infertility, Fatigue — and 4 related terms.
  • The strongest evidence on file: Eurycoma Longifolia is rated "Possibly Effective" for Sexual desire (Natural Medicines).
  • Also on file: Saw Palmetto is rated "Possibly Ineffective" for Benign prostatic hyperplasia (BPH).
  • Also on file: Maca is rated "Insufficient Reliable Evidence To Rate" for Antidepressant-induced sexual dysfunction, Chronic fatigue syndrome (CFS), Fatigue, Sexual desire, and more.

The evidence for what Forza does is mixed and often limited. Tongkat Ali is rated possibly effective for sexual desire, which aligns with this product's apparent purpose.

Saw Palmetto is rated possibly ineffective for benign prostatic hyperplasia (enlarged prostate), despite being a common ingredient in such products. For most of the other active ingredients — Maca, Macuna Pruriens, Muira Puama, and the rest — the evidence we hold is insufficient to rate their effectiveness for any claimed use.

That doesn't mean they don't work; it means the clinical evidence isn't established in the data we have.

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 5 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 5 of 5.
  • General safety write-ups exist for 5 of 5.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Saw Palmetto is generally well tolerated but can cause mild, reversible side effects like abdominal pain, constipation, diarrhea, dizziness, fatigue, headache, nausea, and decreased libido; rarely, it's been tied to heart rhythm issues and blood pressure changes. Macuna Pruriens is also generally well tolerated when taken orally, with the most common side effects being diarrhea, flatulence, and mucosal irritation; in clinical studies, some participants reported nausea, abdominal bloating, vomiting, and insomnia.

Maca is well tolerated as a food but hasn't been studied long-term as a supplement; raw, uncooked maca may cause stomach pain. Because several ingredients contain compounds that affect hormones or have drug-like activity, they should be avoided during pregnancy and breastfeeding — safety data are either insufficient or advise against use in both situations.

Known Interaction Concern · database check
Major identified

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

Why this rating?
  • 3 of the 5 matched ingredients can interact with medications — Saw Palmetto, Cowhage, Eurycoma Longifolia.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications; Parkinson's medications.
  • For scale: 533 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.

Check your medications against these drug types before taking Forza: blood pressure medications (especially methyldopa and propranolol), blood thinners and antiplatelet drugs, birth control and estrogen therapy, monoamine oxidase inhibitor antidepressants (MAOIs), levodopa for Parkinson's disease, blood sugar medications, antipsychotics, tricyclic antidepressants, anesthetics, and the medication guanethidine. Several ingredients contain compounds with drug-like activity and pose real risks with common prescriptions.

Horny Goat Weed, Powder6 drug types · 963 drugs

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.
In vitro, horny goat weed leaf extract inhibits CYP1A2. This effect has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2B6 (Cyp2B6) 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, Powder full monograph & interactions

Tongkat Ali, Powder5 drug types · 248 drugs

Propranolol (Inderal)

Eurycoma longifolia can reduce the levels and clinical effects of propranolol.
A small clinical study in healthy persons shows that taking a single dose of a water-based Eurycoma longifolia extract 200 mg, in combination with a single dose of propranolol 80 mg, reduces the propranolol area under the curve (AUC) by 29%, reduces the peak concentration by 42%, and increases time to peak concentration by 86% when compared with control. Since the elimination half-life of propranolol did not change, it seems that Eurycoma longifolia alters the kinetics of propranolol by decreasing its absorption in the gut, and not by altering its metabolism. It is not known if separating administration will prevent this interaction.

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

Theoretically, Eurycoma longifolia might increase levels CYP1A2 substrates.
In vitro research suggests that methanolic Eurycoma longifolia root extract weakly inhibits CYP1A2 enzymes. This effect has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2A6 (Cyp2A6) Substrates

Theoretically, Eurycoma longifolia might increase levels of CYP2A6 substrates.
In vitro research suggests that methanolic Eurycoma longifolia root extract weakly inhibits CYP2A6 enzymes. This effect has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2C19 (Cyp2C19) Substrates

Theoretically, Eurycoma longifolia might increase levels of CYP2C19 substrates.
In vitro research suggests that methanolic Eurycoma longifolia root extract weakly inhibits CYP2C19 enzymes. This effect has not been reported in humans.

Likelihood Possible Evidence D
Testosterone

Theoretically, Eurycoma longifolia may further increase levels of testosterone.
A clinical study in aging males with testosterone levels below 300 ng/dL shows that taking a specific water extract of Eurycoma longifolia roots (Physta; Biotropics Malaysia) 100-200 mg daily with breakfast for 12 weeks increases total testosterone levels by 8% to 11% when compared with placebo. It is unclear whether this increase would occur in individuals with normal testosterone levels.

Likelihood Possible Evidence D

Macuna Pruriens seed extract8 drug types · 193 drugs

Levodopa

Concomitant use can increase the risk of levodopa-related adverse effects.
Cowhage contains levodopa. Some cowhage products have been standardized to contain 75-400 mg of levodopa per dose.

Likelihood Likely Evidence D
Methyldopa (Aldomet)

Theoretically, concomitant use of cowhage and methyldopa might increase the risk of hypotension.
Cowhage contains levodopa. Use of levodopa with methyldopa might cause additive hypotension. In addition, methyldopa may inhibit peripheral decarboxylation of levodopa and increase levodopa levels in the central nervous system; avoid using.

Likelihood Probable Evidence D
Monoamine Oxidase Inhibitors (Maois)

Theoretically, concomitant use of cowhage and non-selective MAOIs might increase the risk of hypertensive crisis.
Cowhage contains levodopa. Use of levodopa with non-selective MAOIs might cause hypertensive crisis. However, this interaction has not been reported with MAO-B selective inhibitors such as selegiline.

Likelihood Probable Evidence D
Anesthesia

Theoretically, concomitant use of cowhage and anesthesia might increase the risk of arrhythmias.
Cowhage contains levodopa. Use of levodopa with cyclopropane or halogenated hydrocarbon anesthesia has led to arrhythmias. Other anesthetics have not been implicated. Use other anesthetics in patients taking cowhage or tell patients to stop taking cowhage at least 2 weeks before surgery.

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.

Forza by Totally Products: Common Questions

Does Forza by Totally Products interact with any medications?
Yes. Based on its ingredients, Forza has a known interaction with 1,141 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?
Forza contains 9 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 Forza while I'm pregnant or breastfeeding?
No. The safety data advises against it. Saw Palmetto and Macuna Pruriens are both rated likely unsafe or unsafe in pregnancy because of hormonal effects and lack of safety study. Maca, Tongkat Ali, and Muira Puama don't have enough safety information either. Talk with your doctor or pharmacist for personalized advice if you're pregnant or nursing.
What is Macuna Pruriens and why does it matter in this product?
Macuna Pruriens, also called cowhage, is a seed extract that contains levodopa — the same active compound used to treat Parkinson's disease. That makes it act like a medication in your body, which is why it has Major-severity interactions with certain blood pressure drugs and antidepressants. It's not a simple herbal ingredient.
Does this product have any fillers?
Yes. The inactive ingredients are rice flour, gelatin, and magnesium stearate — these are excipients that help bind and fill the capsule. They're standard in supplement capsules.
What's the most common side effect I might notice?
Saw Palmetto and Macuna Pruriens, the two largest active ingredients by interaction profile, most commonly cause mild digestive upset — things like diarrhea, constipation, flatulence, nausea, or abdominal pain. These are usually mild and reversible, but they're worth knowing about.
Does Forza actually work for sexual function?
Tongkat Ali is rated possibly effective for sexual desire, which is the strongest evidence claim in this product. The other ingredients — Maca, Muira Puama, Macuna Pruriens, and the rest — don't have enough established clinical evidence for us to say whether they work for that purpose.
Why can't you check some of the ingredients for interactions?
We don't hold interaction data for Panax ginseng, Arginine, Icariin, Polypodium vulgare, or the individual components of Horny Goat Weed in our monographs. That doesn't mean they're safe with all medications — it just means we couldn't verify their interactions for you. Always run your full medication list through our checker.
