9 Supplements That May Improve Your Sexual Health and Libido

On This Page

    A healthy sex life is often an important part of a person’s life. Read on to learn about supplements that can support your sexual health.

    What can cause low sex drive

    Low sex drive can have many causes. Some of them include questions of emotional health and mental health. Others, though, are the result of hormonal changes in the body or a lack of overall physical health. Sometimes, to boost your sex drive, you only need to make some small lifestyle adjustments.

    Can supplements actually help boost sex drive?

    If you’re looking to boost your sex drive, be encouraged: there are steps you can take. Making sure you’re keeping your body in good health through a healthy lifestyle – including diet and exercise – can make a difference in all areas of health, including sex drive. But there’s also some evidence now to suggest that supplements can be part of your solution, too. Supplements can help with the production of sex hormones, which are essential for sexual function and reproduction, and they can also support for the strength and vitality of the body generally. Read on to learn about what supplements might be good for you.

    Supplements that can help boost sex drive

    Vitamin B3 (Niacin)

    Studies on the effect of vitamin B3 (niacin) on sexual health are still not conclusive. Here’s what we can say, though: Per a recent study, niacin is associated with improved blood flow in middle aged and older adults. More specifically, the study looked at niacin’s positive effect on the endothelium – the thin cell lining that lines your blood vessels and plays an important role in blood flow and sexual health.

    Vitamin D

    Vitamin D deficiency is strikingly common, with about 42% of Americans experiencing it. It turns out that not getting enough vitamin D can actually have effects on sexual health.

    One study examined the relationship between vitamin D and testosterone levels. A key finding of this study was that for men with a vitamin D deficiency, taking vitamin D supplements boosted testosterone levels and supported better sexual function. Another study – this one an analysis of sex hormones in older men – found the same correlation regarding testosterone and vitamin D: The men who took the vitamin D supplement saw an increase in testosterone.

    A study of post-menopausal women likewise found that individuals who maintained normal vitamin D levels had less severe symptoms and had better overall sexual function.


    There’s good evidence to suggest that ginseng – particularly red ginseng – can increase sex drive and improve sexual health, for both men and women.

    Consider, for example, a systematic review of 10 studies that looked at the effect of red ginseng on menopausal women. The review found strong positive evidence that ginseng increased sexual function and sexual desire.

    Moreover, ginseng may promote the body’s production of nitric oxide, a compound that helps with blood circulation and helps the muscles in the penis relax. Studies of men with sexual dysfunction have shown that men who took ginseng have had greater success in boosting sexual health than those who took a placebo. A review of 9 studies involving nearly 600 men experiencing sexual dysfunction found the same thing – that ginseng very well may improve sexual function compared with the placebo. All this being said, more research is still needed.


    Maca is a root vegetable that has been studied for its ability to improve sexual health and sex drive.

    One four-month study focused on nine men who were given 1,500-3,000 mg per day of maca supplements. The maca treatment resulted in increased sex drive and sexual performance. Another study of twenty volunteers found that maca had fertility enhancing properties for men.

    Moreover, a pilot investigation examined the effect of maca supplementation on physical activity and sexual desire in sportsmen. The study found that 14 days of maca supplementation for active cyclists ended up improving their cycling times as well as boosting their sexual desire.


    Taking a good multivitamin can help fill in gaps from what’s missing in your diet. Getting enough vitamin E has been shown to improve sexual health for men, while getting enough vitamin C can support cardiovascular health and blood flow, both of which affect sexual health. You may also want to think about a magnesium supplement, as low magnesium levels have been linked to poor sexual function.


    Zinc has strong antioxidant qualities, which can be good for sexual health. Studies show that maintaining healthy zinc levels is essential for male sexual health, while toxic levels of zinc can have the opposite effect. The recommended upper limit for zinc intake is 40mg in adults and toxicity is rare. Zinc is also vitally important for the immune system, and can act as a hormone balancer.

    L-arginine and L-citrulline

    L-arginine is an amino acid that promotes nitric oxide production – which, as discussed above, can be good for sexual health. It also increases blood flow and helps with the dilation of blood vessels. It’s found naturally in some foods, including red meat, nuts and seeds, dairy, and whole grains.

    L-citrulline is an amino acid that your body naturally produces and then converts into L-arginine, helping produce nitric oxide and potentially supporting healthy sexual function in men.

    A small study found that taking 1.5 grams of L-citrulline daily helped improve sexual health in half of the men who participated. Another study of men found that taking a daily combination of 800 mg of L-citrulline and 300 mg of trans-resveratrol – in concert with a prescribed sexual health medication – improved sexual function in men. In addition to its supplement form, L-citrulline is found in watermelon and cucumbers.


    Dehydroepiandrosterone (DHEA) is a major blood hormone (steroid) naturally made in our bodies. While it’s the most abundant circulating steroid hormone in humans, levels of DHEA decline with age. In women, DHEA has been shown to improve sexual satisfaction and sexual health. One study found that postmenopausal women who were given 300 mg of DHEA experienced great mental and physical arousal in comparison to those who were given a placebo.


    Ashwagandha is an adaptogen that has been shown to promote sexual health. A 2015 study found that ashwagandha supplementation considerably boosted female sexual function compared with the placebo group. Moreover, a 2013 study found that ashwagandha supplementation led to increased sexual desire and sexual functioning for men. Care/of offers a top-notch ashwagandha supplement, harvested in India.
