Several supplements show genuine promise for improving sexual desire in women, though the strength of evidence varies. The best-studied options include ashwagandha, maca root, fenugreek, and ginkgo biloba, each working through different pathways. Some target stress hormones, others support blood flow or nudge testosterone levels upward. Which ones are worth trying depends on what’s driving the low libido in the first place.
Ashwagandha for Stress-Related Low Desire
Chronic stress is one of the most common libido killers, and ashwagandha is the supplement with the strongest evidence for addressing that link. It works by lowering cortisol, your body’s main stress hormone, which in turn helps restore the hormonal balance that supports sexual desire. In a pilot study of otherwise healthy women with sexual difficulties, those taking ashwagandha root extract for eight weeks saw their sexual function scores rise to 23.86, compared to 20.06 in the placebo group. The improvement was statistically significant at both the four-week and eight-week marks, covering desire, arousal, lubrication, and orgasm.
That four-week checkpoint is worth noting. If stress and mental fatigue are tanking your sex drive, ashwagandha is one of the faster-acting options, with measurable changes appearing within a month of consistent daily use.
Maca Root: Modest but Real Effects
Maca is probably the most widely marketed “libido supplement” for women, and the research tells a more nuanced story than the marketing does. A 12-week placebo-controlled trial tested 3 grams per day (split into two 1,500 mg doses) in women experiencing sexual dysfunction caused by antidepressant medications. Overall, maca didn’t significantly outperform the placebo on total sexual function scores.
But the subgroup results were more interesting. Postmenopausal women on maca showed meaningful improvement in orgasm, while premenopausal women saw improvement specifically in arousal. So maca may help, but the benefits appear to be targeted rather than universal, and they depend partly on your life stage. If you’re postmenopausal and struggling more with orgasm than with desire itself, maca has a reasonable case. At 3 grams per day, it’s also considered safe with minimal side effects.
Fenugreek and Free Testosterone
Testosterone isn’t just a male hormone. Women produce it in smaller amounts, and it plays a direct role in sexual desire. Fenugreek extract appears to work by increasing the amount of free, usable testosterone circulating in your body. In a 12-week trial, 1,800 mg per day of a fenugreek extract raised saliva testosterone by nearly 20% and increased the free testosterone index by about 12% compared to baseline.
These are modest hormonal shifts, not dramatic ones, which is actually reassuring from a safety standpoint. The testosterone boost is enough to potentially support desire without pushing levels into a range that causes unwanted side effects like acne or facial hair. Fenugreek is a reasonable option if you suspect your low libido has a hormonal component, particularly if you’re in your late 30s or 40s when testosterone naturally starts declining.
Ginkgo Biloba for Antidepressant Side Effects
If your low libido started after beginning an antidepressant, ginkgo biloba deserves special attention. An open trial found it was 84% effective at treating antidepressant-induced sexual dysfunction, and women responded even better than men, with a 91% success rate compared to 76%. The effects covered all four phases of the sexual response cycle: desire, arousal, orgasm, and the sense of satisfaction afterward.
Dosages in the trial ranged from 60 mg once daily to 120 mg twice daily, with an average of about 209 mg per day. One important caveat: this was an open-label trial, meaning participants knew they were taking ginkgo, which can inflate results through placebo effects. Still, the response rates were high enough to make it worth discussing with whoever prescribes your antidepressant, since ginkgo can interact with certain medications, especially blood thinners.
DHEA for Postmenopausal Women
DHEA is a hormone your body naturally produces and converts into both estrogen and testosterone. After menopause, DHEA levels drop substantially, which contributes to vaginal dryness, reduced arousal, and lower desire. Supplementation has been explored as a way to partially reverse this decline.
The dosage matters considerably. A meta-analysis of randomized controlled trials found that doses of 50 mg per day or higher significantly raised both testosterone and estrogen levels in postmenopausal women. Lower doses had no meaningful hormonal effect. For women over 60, the same 50 mg threshold was needed to raise estrogen levels specifically. However, the overall evidence on whether these hormonal changes translate into noticeably better sexual function is described as “modest.” DHEA is best thought of as a supporting player rather than a standalone solution, particularly useful alongside other interventions for menopause-related sexual changes.
Iron Deficiency: The Overlooked Factor
This one isn’t a trendy supplement, but it may be the most impactful on this list for women who are affected. Iron deficiency anemia is remarkably common in women of reproductive age, and it has a direct, measurable relationship with sexual function. In a study comparing women with iron deficiency anemia to healthy controls, every dimension of sexual function and satisfaction was significantly lower in the anemic group. Ferritin levels (your body’s iron storage marker) showed a strong positive correlation with sexual desire specifically.
The anemic women had average ferritin levels around 10, compared to 61 in the healthy group. When anemic women received treatment to restore their iron levels, their sexual function scores improved significantly and their anxiety scores dropped. If you experience heavy periods, fatigue, shortness of breath with exercise, or brain fog alongside low libido, a simple blood test for ferritin could reveal a highly treatable cause. This is one situation where fixing a nutritional gap can produce dramatic improvement.
L-Arginine and Blood Flow
Sexual arousal in women depends on increased blood flow to genital tissues, which produces lubrication and heightened sensitivity. This process relies on nitric oxide, a molecule your body makes from the amino acid L-arginine. The pathway works the same way in women as in men: nitric oxide relaxes blood vessels and increases circulation to the genitals during arousal.
An enzyme called arginase competes for L-arginine in vaginal tissue, essentially diverting it away from nitric oxide production. This means that supplementing with L-arginine could, in theory, tip the balance toward better blood flow and arousal. The mechanistic research is solid, but clinical trials in women are still limited. L-arginine is most likely to help if your main complaint is poor physical arousal (difficulty with lubrication or sensation) rather than absent desire.
How Long Before You Notice a Difference
Most women in clinical trials don’t report meaningful changes until at least three to four weeks of consistent daily use. Ashwagandha showed statistically significant improvement at the four-week mark. Testosterone-related effects from supplements like fenugreek or DHEA follow a similar pattern, with research on testosterone treatment showing that effects on desire, sexual thoughts, and satisfaction typically emerge after about three weeks and continue building from there.
Maca trials ran for 12 weeks before assessing outcomes, and the fenugreek testosterone study measured results at 12 weeks as well. If you’re going to try a supplement, commit to at least four to six weeks before deciding it isn’t working. Taking something for a few days and expecting results isn’t a fair test of any of these options.
Choosing the Right Supplement
The most effective approach is matching the supplement to the likely cause of your low libido:
- High stress or anxiety: Ashwagandha has the clearest evidence for stress-driven desire problems.
- Antidepressant side effects: Ginkgo biloba showed the highest response rates in this specific population.
- Hormonal decline with age: Fenugreek for perimenopausal women, DHEA (50 mg or more) for postmenopausal women.
- Fatigue and heavy periods: Get your ferritin checked. Iron supplementation can transform sexual function if deficiency is the root cause.
- Poor physical arousal: L-arginine targets the blood flow pathway directly, and maca may help with arousal in premenopausal women.
Stacking multiple supplements without identifying the underlying issue is less effective than targeting the right one. Low libido in women is rarely just one thing, but starting with the most likely contributor gives you the best chance of noticing a real difference.
