And what about L-citrulline? Watermelon has the highest concentration in nature (particularly the white rind), followed by onions and garlic. Just one standard serving of yellow watermelon provides enough L-citrulline to boost sexual performance. My advice is that you might want to stick to watermelon and not onions and garlic to boost your nitric oxide production before going on a date!

L-arginine is an amino acid that is necessary for the lining of the blood vessels to produce nitric oxide. Nitric oxide allows the blood vessels to relax, thus improving blood flow throughout the body, including to the penis. Studies on L-arginine and erectile dysfunction have used between 2,000-5,000 mg a day in divided doses.ii Supplemental arginine is best taken on an empty stomach.3

Erectile dysfunction (ED) or impotence is very common in men with one in 5 men affected by it. Though medical and psychological interventions are sought as treatment, natural remedies have been used traditionally to cure the condition. While foods like onion, garlic, ginger, carrots, and pomegranate juice are known to cure ED, certain vitamins like vitamin C, E, and B3 are effective, too. You may want to try Korean Red Ginseng or supplement your diet with L-arginine. You could also give acupuncture a shot.


The Institute of Medicine recommends cumulative daily vitamin D intake of 600 international units (IU) for adults between 18 and 70 years of age , and 800 IU for those over 80. A 3oz serving of salmon contains about 450IU, while an 8oz. glass of milk only has about 100IU. Low vitamin D levels may be an independent, potentially modifiable risk for ED, so it’s worth taking Vitamin D supplements for your “D.” However, keep your daily vitamin D supplement intake below 4,000IU, as too much vitamin D can be toxic.

A recent study in the journal Circulation found that flavonoids in dark chocolate improve circulation. That could be good for erection problems that are due to poor circulation. Flavonoids are naturally-occurring antioxidants that protect plants from toxins and help repair cell damage. Studies show that flavonoids and other antioxidants have similar effects on people. They may help lower blood pressure and decrease cholesterol, both of which are factors that contribute to erectile dysfunction.

A study in the Journal of Sexual Medicine found that a large percentage of men with ED also have low levels of vitamin D. If you’re experiencing ED, you may want to have your level of vitamin D checked. Other symptoms of a low vitamin D level may be too subtle to notice. However, if you have serious vitamin D deficiency, you may have bone pain or muscle weakness. Vitamin D levels can be checked with a simple blood test and for most people corrected with a supplement.

In contrast to Chinese ginseng, Korean ginseng is divided into three types, depending on how it is processed. Red Ginseng is harvested at the sixth year of cultivation and is steamed and dried. In addition to the effects mentioned regarding the effects of ginsenoside, red ginseng has been repoted to improve erectile function in a rat model of metabolic syndrome and it was also found to inhibit fibrosis of the corpus cavernosum of the penis (39). As with most herbal medicines, the concentration of ginsenoside are distributed unevenly throughout the ginseng plant and the concentrations in individual supplements can vary. Common side effects include headaches, insomnia, gastric upset, rash and constipation.


Consider this:  penicillin, the first successful antibiotic, was derived from molds that inhibit bacterial growth.  Scientists had to figure out why the molds slowed bacteria, and refine the active ingredients.  Using herbal supplements is somewhat like putting mold on a wound.  It might help, a little, but it’s certainly not going to help as much as using penicillin.
ED is often treated with psychotherapy, behavior modification techniques, oral medications, locally injected drugs, vacuum devices, and sometimes even surgically implanted devices. In rare cases, surgery of the blood vessels may be necessary. In most cases, even when a physical cause is identified, emotional or psychological factors play a role as well.

Some of these products contain unknown amounts of ingredients similar to those in prescription medications, which can cause dangerous side effects. Some actually contain the real drug, which should be given by prescription only. Although the Food and Drug Administration has banned many of these products, some potentially dangerous erectile dysfunction remedies remain on the market.
