Vitamins and supplements play crucial roles in maintaining overall health and wellness, which may extend to improving erectile function. From vitamin D, which might influence testosterone production and blood flow, to L-arginine and its role in nitric oxide synthesis for better penile blood flow, we explore the scientific insights and existing research surrounding these nutrients.

Despite the lack of definitive proof tying specific vitamins directly to enhanced erectile function, their overall benefits to health might indirectly support erectile health.

While there are no magic bullets here and no “cures,” this article provides a comprehensive overview of 10 vitamins and supplements that may contribute to preventing or improving erectile dysfunction.

1. Vitamin D

Vitamin D plays a significant role in maintaining optimal bodily functions. It helps bone health, the immune system, and cellular function. Research has also found that it may play a role in healthy erections as well.

Some medical studies found no connection between vitamin D and erectile function. It may very well be a case of vitamin D not boosting erections when present but making ED more likely when its levels are low.

Bottom line? Vitamin D could be an indirect ED prevention booster. It may help the body maintain adequate blood flow to the penis and even boost testosterone production. Researchers admit they don’t know enough about how vitamin D influences erectile function and recommend further research.

In the meantime, if you’d like to enhance your vitamin D levels, you may not need to take supplements — your body synthesizes vitamin D from sunshine. Spend time outdoors, but wear sunscreen to avoid skin damage if you spend a lot of time outside.

2. Vitamin B9 (Folic Acid)

Several studies have found that men with ED tend to have lower folic acid levels than healthy controls. A meta-analysis pooling data from multiple studies confirmed that ED patients had significantly lower folic acid levels, with the difference being more pronounced in more severe cases of ED. The study also found that supplementing with folic acid significantly improved ED scores.

One proposed mechanism is that folic acid reduces oxidative stress, regulates blood pressure, stimulates nitric oxide production, and improves penile blood flow, all of which facilitate healthy erections.

The relationship between folic acid and ED is still not fully clear, as not all studies have found a significant association. Larger, well-designed trials are needed to better understand if and how folic acid supplementation can help manage ED in different patient populations.

However, the available evidence suggests that maintaining adequate folic acid levels, through a healthy diet and possibly supplementation, may support erectile function and overall male sexual health. Men with ED, especially those not responding to oral ED medications, may wish to have their folic acid levels tested.

To get more vitamin B9 into your system, eat foods like whole grains, fresh fruits, green leafy vegetables, and sunflower seeds.

3. Vitamin B3 (Niacin)

Vitamin B3 fulfills many essential roles, including converting enzymes to energy. It reduces inflammation and boosts blood flow, possibly supporting erectile function.

Researchers found that in patients with high cholesterol levels, niacin can improve erections significantly. According to some studies, high doses of niacin taken over several months may improve erectile function.

Like other vitamins and supplements, vitamin B3 may help in ED prevention. Doctors know little about how much niacin one should take to secure its erection-protecting benefits. They recommend more research.

Taking vitamin B3 to boost your overall health may make scientific sense, and a healthy body is more likely to produce healthy erections.

To reap B3’s potential ED prevention benefits, eat more niacin-rich foods. Dietary sources of niacin include turkey, chicken, beef, fish, nuts, and seeds.

4. L-arginine

This amino acid has gained attention for its potential to improve erectile function without the side effects of traditional ED medications.

So, what does the science say? A recent systematic review and meta-analysis found that L-arginine supplements, at dosages ranging from 1,500 to 5,000 milligrams per day, significantly improved ED compared to placebo or no treatment. Men taking L-arginine had better scores on the International Index of Erectile Function (IIEF) in areas like overall satisfaction, intercourse satisfaction, orgasmic function, and erectile function.

One study even found that high-dose L-arginine (2,500 milligrams per day) for three months significantly improved penile blood flow and erectile function in men with mild to moderate ED from vascular causes. L-arginine seems to work by boosting nitric oxide production, leading to improved blood flow in the penis.

L-arginine may also enhance the effects of prescription ED medications. One study found that a combination of L-arginine (2,500 milligrams) and 5 milligrams of the drug tadalafil (Cialis) taken daily for 12 weeks was superior to either treatment alone in improving ED. The combination was effective for mild, moderate, and severe ED.

While L-arginine shows promise as a natural remedy for ED, it’s important to talk to your doctor before trying it, especially if you have low blood pressure or are taking ED medications, as there is a potential for an additive blood pressure lowering effect.

5. Vitamin C

Vitamin C is a powerful antioxidant that may play a role in supporting erectile function, although more research is needed to confirm the relationship. By helping with nitric oxide availability, vitamin C supports endothelial and vascular function, which is crucial for achieving erections.

Some studies have found that vitamin C supplementation may help protect against risk factors for erectile dysfunction, such as high blood pressure, oxidative stress, and endothelial dysfunction. These antioxidant properties may help prevent damage to penile tissues.

Vitamin C can also regenerate other antioxidants, like vitamin E, that support testosterone production in the testes. This may act to preserve libido and erectile function, but more studies are needed to confirm this connection.

Nonetheless, ensuring adequate vitamin C intake as part of a healthy diet may provide some additional support for overall vascular and sexual function.

6. Ginseng

Used as a herbal tonic in traditional Chinese medicine, ginseng may have anti-cancer, anti-diabetes, and antioxidant effects. It may also boost erectile function by streamlining nitric oxide synthesis.

Scientific evidence concerning its many purported benefits is scant, however. Researchers found that ginseng may boost men’s self-reported ability to have intercourse. Korean red ginseng may also boost erectile function directly.

A 2019 study focused on combining ginseng with vitamin E to improve erections. Researchers concluded that the combination may work, warranting further research.

7. DHEA (Dehydroepiandrosterone)

DHEA is a steroid prohormone. The body uses it to create other hormones, including testosterone. It wouldn’t be wrong to call DHEA a hormone of youth since its levels are much higher in younger individuals than in the elderly.

Starting at the age of 30, DHEA levels begin to decline. By age 70 to 80, some men only retain about 10 percent of their DHEA. Research shows that individuals with low DHEA levels are more likely to also suffer from ED.

This is even more likely in men who are overweight. DHEA is converted into estrogen in adipose (fat) cells, so even in young men, obesity may interfere with its conversion to testosterone, making more estrogen instead, which opposes the actions of testosterone.

Oral supplementation may help boost DHEA levels, though researchers recommend further large-scale prospective studies to determine DHEA’s therapeutic potential for ED.

8. L-carnitine

An essential amino acid derivative, L-carnitine helps the body metabolize fat, produce sperm, and maintain cardiovascular health. The body produces all the L-carnitine one may need, but supplements have existed for some time.

Athletes may take L-carnitine supplements to boost performance and shorten recovery times.

Scientists have found that L-carnitine improves nocturnal erections. In this sense, it may work better than testosterone.

L-carnitine may contribute to healthy erectile function in other ways as well. The compound may also promote organ regeneration and counter the fibrosis of the penis.

9. Citrulline

Medical studies show that L-citrulline supplementation can help with acute bouts of erectile dysfunction that are consequences of poor penile blood flow.

Unlike L-arginine, L-citrulline goes through the digestive system intact and turns into L-arginine. If you want to boost your NO production through L-arginine supplementation, L-citrulline is a good option.

Researchers combined L-citrulline with FDA-approved PDE-5 inhibitors to boost their effects. They concluded that citrulline can make on-demand PDE-5 inhibitors more effective. L-citrulline also improves erection quality in men suffering from mild ED.

To ensure you get enough L-citrulline, include foods like cucumbers, pumpkins, and watermelons in your diet.

10. Vitamin B12 (Cobalamin)

If you have a vitamin B12 deficiency, you will likely experience ED and possibly other forms of sexual dysfunction. Low B12 levels may also cause premature ejaculation.

Cobalamin supports bodily functions like red blood cell production, DNA synthesis, and nerve function. It may also have an impact on erections, though not all studies agree.

Regardless of the scientific consensus about vitamin B12’s effects on erections, you should ensure that you get enough of this essential nutrient. Other symptoms of vitamin B12 deficiency include muscle cramps, dizziness, anemia, fatigue, and depression.

To get enough vitamin B12, eat foods like shellfish, eggs, red meat, nutritional yeast, dairy products, and poultry.

How We Ranked Them

To rank these vitamins and supplements, we looked at the frequency and prominence of mention in scientific literature, as well as factors like:

• Directness of evidence. Some vitamins and supplements like L-arginine are directly involved in erectile function, through the NO pathway or otherwise.
• General health benefits. Vitamins C and B support many bodily functions and, through them, indirectly benefit erectile function.
• Traditional and anecdotal support. Some supplements, like ginseng, boast traditional applications and modern research.
• Emerging research. Some entries, like citrulline, have only recently emerged as possible ED treatment options. The body of evidence supporting their efficacy is thin but may be promising.

The Bottom Line

In most cases, the evidence isn’t conclusive that these vitamins and supplements can prevent ED, but the research certainly is suggestive of positive connections. Many provide some level of benefit, especially to men with vitamin deficiencies.

Currently, however, PDE5 inhibitor medications like Viagra, Cialis, Stendra, or vardenafil (formerly Levitra) are the most effective treatments for ED. They have been well studied and approved by the FDA for that purpose.

It’s also important to note that the effectiveness of vitamins and supplements to prevent ED will vary from one individual to another. Some may interact with other medications you take, and not all are safe for everyone. Speak with your doctor before making any major changes to your health regimen.
