HelloPharmacist Scorecard of Women's Libido Support by Fortify

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 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.

Fortify Women's Libido Support contains 9 ingredients, including L-arginine, Panax ginseng powder, Maca powder, Saw Palmetto berry powder, Tongkat Ali (Eurycoma longifolia) powder, Muira Puama powder, Polypodium vulgare powder, Icariins, and Tribulus terrestris aerial parts extract. The first six and Tribulus are the active ingredients; the others serve roles in the formulation or are proprietary components.

The supplement also contains inactive ingredients — rice flour, gelatin, and magnesium stearate — to form and stabilize the capsules.

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: Women's libido and sexual function support.
  • We looked for evidence on: Sexual desire, Sexual dysfunction, Antidepressant-induced sexual dysfunction, Erectile dysfunction (ED), Fatigue, Menopausal symptoms — 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.

The evidence for this product's ingredients is mixed and often limited. Tribulus terrestris and Tongkat Ali each have possibly effective ratings for sexual dysfunction, though the body of research remains small.

Saw Palmetto is rated possibly ineffective for benign prostatic hyperplasia (enlarged prostate), which is not a women's health concern. For most other uses listed — including amenorrhea, anemia, athletic performance, osteoporosis, and back pain — the evidence we have is insufficient to make a reliable rating.

The effectiveness of Maca, Muira Puama, and other ingredients for women's libido has not been established in the data we hold.

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; it's not considered safe for everyone and should be used only under medical supervision. Common oral side effects include abdominal pain, bloating, nausea, diarrhea, headache, insomnia, and flushing.

Maca is generally well tolerated as a food but has not been studied long-term in supplement amounts; it may cause stomach pain if fresh and uncooked. Saw Palmetto is well tolerated in adults with mild and reversible side effects — abdominal pain, constipation, diarrhea, dizziness, fatigue, headache, nausea, and rarely a rash or skin reaction; occasional heart rhythm changes have been reported.

Tribulus is generally well tolerated short-term, though rare serious effects (liver and kidney injury, seizures) have been reported. Tongkat Ali is generally tolerated short-term, but long-term safety is uncertain; it may raise testosterone, which if pushed too high can cause acne, insulin resistance, and liver injury.

Muira Puama has limited human safety data. None of these ingredients should be used during pregnancy or breastfeeding — safety information is insufficient or the data advises against it.

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 Fortify Women's Libido Support, have your pharmacist review these medications: blood pressure drugs (antihypertensives, ACE inhibitors, ARBs), blood thinners (anticoagulants and antiplatelets), potassium-sparing diuretics, diabetes medications, beta-blockers like propranolol, hormonal contraceptives, estrogens, and lithium. L-arginine and Tribulus can lower blood pressure and blood sugar; L-arginine, Saw Palmetto, and other ingredients may increase bleeding risk or interfere with hormonal birth control.

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 combines several ingredients with research suggesting they may support sexual desire, but the evidence is often insufficient. The main concern is L-arginine and several other ingredients that can interact with blood pressure medications, blood thinners, diabetes drugs, hormonal contraceptives, lithium, and other medications.

If you take any prescription drugs — especially for blood pressure, heart rate, blood sugar, clotting, or hormones — check with your pharmacist before starting this.

Likelihood Possible Evidence D
Horny Goat Weed Aerial 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.

Women's Libido Support by Fortify: Common Questions

Does Women's Libido Support by Fortify interact with any medications?
Yes. Based on its ingredients, Women's Libido Support 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?
Women's Libido Support 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.
Is this safe to take if I'm on birth control?
Saw Palmetto in this product may reduce the effectiveness of hormonal contraceptives. Talk to your pharmacist or doctor before adding this supplement to your birth control routine — they may need to adjust your contraception or recommend a different timing or product.
What's L-arginine doing in a women's libido product?
L-arginine is an amino acid that increases nitric oxide in your body, which relaxes blood vessels and may support blood flow and sexual function. It's generally well tolerated when taken by mouth, though it can cause abdominal pain, bloating, nausea, diarrhea, headache, insomnia, or flushing in some people.
Can I take this if I'm on blood pressure medication?
L-arginine and Tribulus terrestris both can lower blood pressure, so combining them with blood pressure drugs may drop your pressure too much. Talk to your pharmacist — they'll let you know if it's safe for you or if your medication needs adjusting.
Is this safe during pregnancy or breastfeeding?
No. L-arginine is possibly safe in pregnancy under medical guidance, but Maca, Saw Palmetto, Tongkat Ali, Tribulus, and Muira Puama should be avoided — there isn't enough safety data, or the data advises against it. Talk with your doctor before taking this while pregnant or nursing.
Does Tribulus actually improve sexual desire?
Tribulus terrestris has a possibly effective rating for sexual dysfunction based on limited research. The evidence is not strong, and long-term safety and product quality vary widely, so results can be unpredictable.
What if I'm on a blood thinner like warfarin?
L-arginine and Saw Palmetto may both increase bleeding risk when combined with blood thinners. Do not take this product without talking to your pharmacist or doctor first — they need to monitor you or adjust your dose.
