Best Supplements to Help with Low Libido in Women

Hypoactive sexual desire disorder (HSDD)—the clinical term for persistently low libido—affects an estimated 10-15% of women. But low libido exists on a spectrum that extends well beyond a formal diagnosis. Stress, hormonal shifts, certain medications (especially SSRIs), relationship dynamics, chronic illness, and nutritional deficiencies all contribute. Effective supplementation requires understanding which factors are primary for you.

This article focuses on well-studied, specific compounds with evidence from human trials. Female libido involves desire, arousal, and satisfaction—different mechanisms, and sometimes different supplements.

The evidence-based options

1. Maca Root (Lepidium meyenii)

Maca is the most consistently studied supplement for female libido with the most compelling human trial evidence. Crucially, its effects appear to be independent of sex hormone levels—maca does not significantly alter estrogen, testosterone, or FSH, yet still reliably improves subjective libido.

Mechanism: Not fully understood. Maca appears to act through the central nervous system rather than via hormonal pathways. It contains glucosinolates, macamides, and macaridine—bioactive compounds that may modulate hypothalamic function and neuroendocrine signaling. Some researchers propose effects on dopaminergic pathways.

Evidence: A 2010 systematic review (BMC Complementary Medicine) identified four RCTs showing maca's efficacy for sexual dysfunction. A 2008 double-blind RCT specifically in postmenopausal women showed 3.5g/day reduced sexual dysfunction scores and improved physical and psychological symptoms of menopause. A 2015 trial in women with SSRI-induced sexual dysfunction (a particularly difficult-to-treat population) showed 3g/day maca improved both libido and orgasm.

Dosage: 1.5-3g/day of gelatinized maca powder or a standardized extract equivalent. Gelatinized form is easier to digest. The typical capsule form is 500-1000mg per capsule. Black maca may have stronger effects for libido than yellow maca, though more evidence exists for yellow.

Timeline: Effects are typically noticed at 4-8 weeks of consistent use. Not an acute intervention.

Safety: Very well-tolerated. One concern: maca's glucosinolate content may modulate thyroid function—take with caution if you have thyroid conditions.

2. Ashwagandha (Withania somnifera)

Ashwagandha addresses one of the most common drivers of low libido in women: chronic stress and elevated cortisol. Cortisol competes with sex hormones at a biochemical level—chronic stress literally suppresses the production and signaling of hormones needed for sexual interest.

Mechanism: Ashwagandha reduces cortisol through HPA axis modulation, and also appears to directly support sexual function. The GABA-mimetic activity of withanolides reduces anxiety, which is itself a major libido inhibitor. Ashwagandha also supports testosterone levels, which (though much lower in women than men) are an important driver of female desire.

Evidence: A 2015 double-blind RCT specifically in healthy women (age 21-50) showed 300mg of ashwagandha root extract twice daily for 8 weeks significantly improved sexual function scores across all domains: desire, arousal, lubrication, orgasm, satisfaction, and pain. The improvements were statistically significant compared to placebo. This remains one of the most directly applicable trials for female libido supplementation.

Dosage: 300-600mg of standardized root extract (KSM-66 preferred) daily. Taking 300mg twice daily (with breakfast and dinner) follows the protocol from the female-specific RCT.

Caution: Consult a healthcare provider if pregnant or breastfeeding. May stimulate thyroid hormone production.

3. Tribulus Terrestris

Tribulus has mixed evidence overall, but several trials specifically targeting female libido—particularly in HSDD—show positive results. It is most commonly associated with testosterone-boosting claims in men (largely unsupported), but in women the mechanism may be different.

Mechanism: Tribulus may influence androgen receptors and support DHEA production. In women, modest increases in androgen activity can meaningfully affect libido. It also appears to have some estrogen receptor activity and may influence nitric oxide pathways.

Evidence: A 2017 RCT (Journal of Dietary Supplements) in women with HSDD used 750mg standardized tribulus extract daily—significant improvements in sexual desire, arousal, and satisfaction were observed compared to placebo. An earlier Iranian study of premenopausal women showed similar improvements in FSFI (Female Sexual Function Index) scores at 7.5mg/kg body weight.

Dosage: 750mg of a standardized extract (40% protodioscin) daily. Divide into two doses with meals. Not recommended for long-term use beyond 90 days without a break.

Note: Evidence is more consistent for female populations than male populations, which is counterintuitive given the typical marketing of tribulus.

4. L-Arginine and L-Citrulline

Female arousal and lubrication depend on nitric oxide (NO)-mediated blood flow to genital tissues—the same mechanism that drives male erectile function, just less discussed. L-arginine and L-citrulline are precursors to nitric oxide synthesis.

Mechanism: L-arginine is converted by nitric oxide synthase to NO, which causes smooth muscle relaxation and vasodilation in genital blood vessels. This increases clitoral and vaginal blood flow, enhancing engorgement and lubrication. L-citrulline is more efficiently converted to arginine in the body than direct arginine supplementation, because it bypasses first-pass hepatic metabolism.

Evidence: A combination L-arginine product (ArginMax for Women) showed significant improvement in sexual desire, satisfaction, and frequency in a 2008 RCT. Earlier trials with L-arginine plus yohimbine showed improvements in postmenopausal women with sexual arousal disorder.

Dosage: L-citrulline 3g/day is typically more effective than equivalent L-arginine doses. If using L-arginine directly, 3-6g/day is required. Pycnogenol (pine bark extract, 40-80mg) is often stacked with L-arginine to enhance NO synthase activity.

Timing: Can be taken 30-60 minutes before sexual activity for acute effect, or daily for cumulative benefit.

5. Ginkgo Biloba

Ginkgo biloba is not commonly thought of as a libido supplement, but it has specific evidence for one of the most common causes of low libido in women: SSRI-induced sexual dysfunction.

Mechanism: Ginkgo improves peripheral circulation (including genital blood flow) and appears to counteract the serotonin-mediated inhibition of sexual response caused by SSRIs. It may enhance both nitric oxide activity and dopaminergic tone.

Evidence: A 1998 study (Journal of Sex & Marital Therapy) found ginkgo effective in 91% of women with SSRI-induced sexual dysfunction. A subsequent larger trial found less dramatic results, but the signal remains meaningful specifically for this population. For women on SSRIs experiencing reduced desire and difficulty reaching orgasm, ginkgo is the most evidence-supported natural option.

Dosage: 120-240mg of standardized extract (24% flavone glycosides, 6% terpene lactones) daily. Divide into two doses. Takes 4-6 weeks for full effect.

Caution: Ginkgo has blood-thinning properties. Do not use with anticoagulants (warfarin), aspirin therapy, or before surgery. Discontinue 2 weeks before any surgical procedure.

6. Saffron (Crocus sativus)

Saffron has an increasingly strong evidence base for both mood and sexual function—particularly relevant for women whose libido is affected by depression or antidepressant use.

Mechanism: The active compounds safranal and crocin influence serotonin, dopamine, and norepinephrine pathways. Crocin appears to reduce the sexual side effects of SSRIs by modulating serotonin receptor sensitivity without blocking the antidepressant effect. Saffron also has mild PDE5 inhibitory activity (the mechanism of sildenafil/Viagra), supporting genital blood flow.

Evidence: A 2012 RCT in women taking fluoxetine showed 30mg/day saffron for 4 weeks significantly improved sexual function scores compared to placebo. A 2013 study in women with major depressive disorder on sertraline showed similar improvements in desire, arousal, lubrication, pain, and overall satisfaction.

Dosage: 30mg daily of a standardized saffron extract. This is the consistent dose across all positive trials. Saffron is dose-sensitive—higher doses do not produce better outcomes and may have adverse effects.

Note: Saffron is relatively expensive, and quality varies significantly. Look for products standardized to safranal content.

7. DHEA

DHEA (dehydroepiandrosterone) is a precursor to both estrogen and testosterone. In women, serum DHEA-S levels decline significantly with age—by approximately 80% from peak levels by age 70. Low DHEA-S is associated with reduced sexual desire, poor genital arousal, and vaginal dryness.

Critical caveat: test first. DHEA is a hormone precursor and can cause acne, hair loss, and other androgenic side effects if taken by women with already-normal or elevated DHEA-S. It is appropriate only for women with confirmed low DHEA-S on laboratory testing.

Evidence: The ECHO trial found that intravaginal DHEA (prasterone) improves sexual desire, arousal, lubrication, and pain in postmenopausal women—it received FDA approval in 2016 for this indication. Oral DHEA at 25-50mg daily also has positive trials for sexual function in women with adrenal insufficiency and postmenopausal women with confirmed deficiency.

Dosage if deficient: 10-25mg oral DHEA daily (lower doses for women). Retest DHEA-S after 8 weeks and adjust accordingly. Use under physician guidance.

What doesn't work (for most women)

Testosterone supplementation without testing: Testosterone does play a role in female desire, but supplementation without confirmed deficiency (via testing) risks virilization symptoms. If testing shows low-normal or low free testosterone, physician-supervised low-dose testosterone therapy is appropriate—but this is a medical treatment, not a supplement intervention.

High-dose single-herb products: Concentrating on one herb at very high doses rarely outperforms the evidence-based doses of the compounds above.

Oyster extract, horny goat weed, damiana: Evidence in women is minimal. Not prioritized until better-studied options have been tried.

Root causes to address first

Before supplementing, identify the primary driver of low libido:

Hormonal (perimenopause/menopause): Declining estrogen and testosterone are the dominant drivers in women 40-55. A full hormonal panel including total and free testosterone, estradiol, FSH, and DHEA-S is essential. Hormone replacement therapy (HRT) is the most effective treatment for menopausal sexual dysfunction—supplements are adjunctive, not primary.

Medication-induced: SSRIs, hormonal contraceptives, antihistamines, and blood pressure medications (particularly beta-blockers) all suppress libido. Identify whether your low libido began or worsened when starting a medication.

Psychological/relational: Libido is bidirectionally connected to relationship satisfaction, body image, past trauma, anxiety, and depression. These factors are often the primary driver and require different interventions than supplements.

Thyroid dysfunction: Hypothyroidism classically reduces libido—it reduces free testosterone, causes fatigue, and impairs mood. Test thyroid function before attributing libido changes to other causes.

Building your stack

Start with the best-evidenced options for your specific driver:

• Stress-driven low libido: Ashwagandha 300mg twice daily
• SSRI-induced: Saffron 30mg + ginkgo 120-240mg
• General/idiopathic: Maca 1.5-3g + L-citrulline 3g
• Arousal-specific (physical response impaired): L-citrulline 3g + pycnogenol 80mg

Introduce one new supplement at a time over 4-week intervals. Most compounds require 4-8 weeks for meaningful results.

When to see a doctor

Seek evaluation if:

• Low libido appeared suddenly or is associated with other symptoms (fatigue, dry skin, hair loss, mood changes)
• You are in perimenopause or menopause—hormonal evaluation is appropriate
• SSRI or contraceptive medication may be a factor—discuss alternatives with your prescriber
• Relationship or psychological factors appear primary—sex therapy has a strong evidence base
• Symptoms persist after 3 months of lifestyle and supplement optimization

Request a full hormonal panel: total and free testosterone, estradiol, FSH, LH, DHEA-S, prolactin, and thyroid function. These provide an actual clinical picture.

The bottom line

Maca has the broadest evidence base for female libido across multiple populations and mechanisms. Ashwagandha specifically addresses stress-driven suppression with a well-designed female-focused RCT supporting it. Saffron and ginkgo are the best options for SSRI-related sexual dysfunction. L-citrulline addresses the physical arousal/blood flow component. The right stack depends on correctly identifying the driver—so start with root cause analysis and testing rather than assuming one supplement fits all presentations.
