HelloPharmacist Scorecard of Femal Libido Formula by PureMax Labs YummyVite

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

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 1 of its 9 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (590 mg) without saying how much of each component you get.
  • “Horny Goat Weed Aerial Plant Extract” is listed as a grouped ingredient — the label gives one combined amount (1,000 mg) without saying how much of each component you get.

Femal Libido Formula contains 9 ingredients, including a proprietary blend. The active ingredients are L-arginine (an amino acid that widens blood vessels), saw palmetto powder, icariin, muira puama powder, maca powder, tongkat ali powder, tribulus terrestris aerial parts extract, horny goat weed aerial plant extract, and panax ginseng powder.

The remaining three ingredients are inactive: rice flour, bovine gelatin (the capsule), and magnesium stearate (a lubricant).

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: Female libido and sexual function support.
  • We looked for evidence on: Sexual desire, Sexual dysfunction, Erectile dysfunction (ED), Antidepressant-induced sexual dysfunction, Premature ejaculation, Fatigue — and 4 related terms.
  • The strongest evidence on file: Tribulus is rated "Possibly Effective" for Sexual dysfunction (Natural Medicines).
  • Also on file: Eurycoma Longifolia is rated "Possibly Effective" for Sexual desire.
  • Also on file: Tribulus is rated "Insufficient Reliable Evidence To Rate" for Chronic fatigue syndrome (CFS), Erectile dysfunction (ED), Menopausal symptoms, Premature ejaculation.

The evidence for this product's ingredients is mixed and mostly limited. Tribulus and tongkat ali show possibly effective ratings for sexual dysfunction; however, most other uses—including maca for sexual dysfunction, muira puama for erectile dysfunction, and tongkat ali for athletic performance—carry insufficient evidence to rate.

Saw palmetto is rated possibly ineffective for benign prostate problems (though possibly effective for a surgical outcome, TURP). The data on file does not establish effectiveness for the product as a whole.

The evidence, ingredient by ingredient L-arginine Saw Palmetto Muira Puama Maca Eurycoma Longifolia Tribulus Horny Goat Weed

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 5 of the 6 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 6 of 6.
  • General safety write-ups exist for 6 of 6.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

L-arginine is generally well tolerated short-term but can lower blood pressure and may not be safe for everyone; safety for self-treatment is not established. Common side effects include abdominal pain, bloating, nausea, diarrhea, headache, insomnia, and flushing.

Saw palmetto is generally well tolerated in adults with mild, reversible side effects (abdominal pain, constipation, dizziness, fatigue, headache, nausea), though rare heart problems have been reported. Tribulus is well tolerated short-term, though serious adverse effects (liver and kidney injury, seizures, painful erection) are rare.

Tongkat ali is generally tolerated short-term, but long-term safety is uncertain; it may raise testosterone beyond normal, risking acne, insulin resistance, and liver damage. Maca, muira puama, and panax ginseng have limited human safety data.

Pregnancy and breastfeeding: L-arginine is possibly safe in pregnancy but has no lactation data; saw palmetto, tribulus, tongkat ali, maca, and muira puama should all be avoided in pregnancy and breastfeeding due to insufficient or no safety information.

Meds to double-check

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?
  • 4 of the 6 matched ingredients can interact with medications — Tribulus, L-arginine, Saw Palmetto, Eurycoma Longifolia.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications; lithium.
  • For scale: 621 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, double-check if you use blood pressure medications (antihypertensives, ACE inhibitors, ARBs, or isoproterenol)—L-arginine and tribulus may lower your pressure further. If you take blood thinners or antiplatelet drugs, both L-arginine and saw palmetto may increase bleeding risk.

Do the same for diabetes medications (L-arginine and tribulus may lower blood sugar), potassium-sparing diuretics (L-arginine may raise potassium too high), estrogens or contraceptives (saw palmetto may reduce their effectiveness), propranolol (tongkat ali reduces its levels), and lithium (tribulus may raise its levels). No interactions are documented for panax ginseng, polypodium vulgare, or icariin in our data.

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 is formulated for sexual function support and contains ingredients with some research backing (tribulus, tongkat ali). However, it has multiple moderate interactions with common medications—blood pressure drugs, blood thinners, diabetes meds, and others—so it's not appropriate for everyone.

Check your medications against this product before starting, and talk to your pharmacist or doctor if you take prescriptions for blood pressure, heart, blood clotting, diabetes, or hormonal conditions.

Likelihood Possible Evidence D
Horny Goat Weed Aerial Plant Extract full monograph & interactions

L-Arginine9 drug types · 403 drugs

Ace Inhibitors (Aceis)

Theoretically, concomitant use of L-arginine and ACE inhibitors may increase the risk for hypotension and hyperkalemia.
Combining L-arginine with some antihypertensive drugs, especially ACE inhibitors, seems to have additive vasodilating and blood pressure-lowering effects. Furthermore, ACE inhibitors can increase potassium levels. Use of L-arginine has been associated with hyperkalemia in some patients. Theoretically, concomitant use of ACE inhibitors with L-arginine may increases the risk of hyperkalemia.

Likelihood Probable Evidence D
Angiotensin Receptor Blockers (Arbs)

Theoretically, concomitant use of L-arginine and ARBs may increase the risk of hypotension and hyperkalemia.
L-arginine increases nitric oxide, which causes vasodilation. Combining L-arginine with ARBs seems to increase L-arginine-induced vasodilation. Furthermore, ARBs can increase potassium levels. Use of L-arginine has been associated with hyperkalemia in some patients. Theoretically, concomitant use of ARBs with L-arginine may increases the risk of hyperkalemia.

Likelihood Probable Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, concomitant use of L-arginine with anticoagulant and antiplatelet drugs might have additive effects and increase the risk of bleeding.
Preliminary research suggests that L-arginine infusions reduce platelet aggregation in humans. The clinical significance of this effect is unclear.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, concomitant use of L-arginine might have additive effects with antidiabetes drugs.
Preliminary clinical research shows that L-arginine decreases blood glucose levels in patients with type 2 diabetes.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, concomitant use of L-arginine and antihypertensive drugs may increase the risk of hypotension.
L-arginine increases nitric oxide, which causes vasodilation. Clinical evidence shows that L-arginine can reduce blood pressure in some individuals with hypertension. Furthermore, combining L-arginine with some antihypertensive drugs seems to have additive vasodilating and blood pressure-lowering effects.

Likelihood Probable Evidence D
Isoproterenol (Isuprel)

Theoretically, concurrent use of isoproterenol and L-arginine might result in additive effects and hypotension.
Preliminary clinical evidence suggests that L-arginine enhances isoproterenol-induced vasodilation in patients with essential hypertension or a family history of essential hypertension.

Likelihood Probable Evidence D
Potassium-Sparing Diuretics

Theoretically concomitant use of potassium-sparing diuretics with L-arginine may increases the risk of hyperkalemia.
Potassium-sparing diuretics can increase potassium levels. Use of L-arginine has been associated with hyperkalemia in some patients.

Likelihood Possible Evidence D
Sildenafil (Viagra)

Theoretically, concurrent use of sildenafil and L-arginine might increase the risk for hypotension.
In vivo, concurrent use of L-arginine and sildenafil has resulted in increased vasodilation. Theoretically, concurrent use might have additive vasodilatory and hypotensive effects. However, in studies evaluating the combined use of L-arginine and sildenafil for erectile dysfunction, hypotension was not reported.

Likelihood Possible Evidence D
Testosterone

Theoretically, concomitant use of L-arginine and testosterone might have additive effects.
In clinical research, L-arginine increases the level of testosterone in male patients with erectile dysfunction. The clinical significance of this finding is unclear.

Likelihood Possible Evidence D
L-Arginine full monograph & interactions

Tribulus terrestris Aerial Parts Extract3 drug types · 259 drugs

Antidiabetes Drugs

Taking tribulus with antidiabetes drugs might increase the risk of hypoglycemia.
Clinical research shows that Tribulus can lower blood glucose levels in adults with type 2 diabetes who are taking antidiabetes medications.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, taking tribulus with antihypertensive drugs might increase the risk of hypotension.
Animal research shows that tribulus can lower blood pressure by inhibiting angiotensin-converting enzyme (ACE). Tribulus has also demonstrated hypotensive effects in pre-hypertensive adults.

Likelihood Possible Evidence D
Lithium

Theoretically, tribulus might increase the levels and clinical effects of lithium.
Tribulus is thought to have diuretic properties. Due to these potential diuretic effects, tribulus might reduce excretion and increase levels of lithium. The dose of lithium might need to be decreased.

Likelihood Probable Evidence D
Tribulus terrestris Aerial Parts Extract 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.

Femal Libido Formula by PureMax Labs YummyVite: Common Questions

Does Femal Libido Formula by PureMax Labs YummyVite interact with any medications?
Yes. Based on its ingredients, Femal Libido Formula has a known interaction with 1,082 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Femal Libido Formula 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 this if I'm pregnant or breastfeeding?
No. Saw palmetto, tribulus, tongkat ali, maca, and muira puama should all be avoided—the safety data advises against them. L-arginine is rated possibly safe in pregnancy, but there's no lactation data for it. Talk to your doctor or pharmacist before using any ingredient in this product if you're pregnant or nursing.
What are the main side effects I might experience?
L-arginine commonly causes abdominal pain, bloating, nausea, diarrhea, headache, insomnia, and flushing. Saw palmetto causes similar digestive upset and dizziness; rarely, heart problems have been reported. Tribulus and tongkat ali are generally well tolerated, though tribulus can occasionally cause serious effects like liver or kidney injury and seizures. Maca may cause stomach pain if uncooked.
Does this product actually work for sexual dysfunction?
Tribulus and tongkat ali are rated possibly effective for sexual dysfunction based on the evidence we hold. Muira puama and maca have insufficient evidence to rate—the research isn't established yet. This is a multi-ingredient product, so real-world results depend on the dose, quality, and your individual response.
Why does this have so many ingredient interactions?
L-arginine, the amino acid in this formula, affects blood pressure, blood sugar, blood clotting, and potassium—systems many medications target. Saw palmetto and tribulus add their own blood pressure and hormone interactions. The total of 618 medications reflects overlap: many blood pressure drugs, for example, all interact with L-arginine.
Is this product safe for long-term use?
The data on long-term safety is limited. L-arginine and tribulus are generally well tolerated short-term in studies, but long-term use isn't well established. Tongkat ali has similar limits, and maca, muira puama, and panax ginseng lack long-term human safety data entirely. Talk to your pharmacist about your duration of use.
What if I'm taking a blood pressure or diabetes medication?
Both L-arginine and tribulus lower blood pressure and blood sugar. Taking either with your medication may cause dangerously low pressure or low blood sugar. Check your exact drugs with the medication checker before starting, and ask your pharmacist whether this product is safe for you.
