5) CoQ10. A study from Germany showed that men with sub par endothelial function were helped by taking CoQ10. That should translate to improved erectile dysfunction. What they found was that blood flow was increased to arm vessels simply by increasing this one nutrient.  This was verified by one recent European study showed something similar: taking 300 mg/day of CoQ10 helped endothelial function by relaxing veins - yes, that means more blood flow throughout the body including the penis - and increasing the body's key antioxidant SOD (which protects your incredibly valuable Nitric Oxide). .  So, yes, even a run-of-the-mill, non-exotic supplement like CoQ10 can improve erectile dysfunction and impotence.
6) Folic Acid. A recent meta-analysis, a study of studies, revealed that folic acid supplementation improved endothelial function and that should improve erectile dysfunction as well. Better blood flow and arterial dilation are good for your sex life and should improve erectile dysfunction while it's at it. After all, you want all the veins in your body, especially the ones in the penis, to be able to expand easily and allow the blood to move freely. Furthermore, researchers found that the higher the dose, the better the result.  Scientists speculate that folic acid's potency may stem from its ability to lower homocyteine levels, which is one of the leading predictors of heart disease. In fact, scientists found that elevated homocysteine levels were as strongly correlated to heart disease as high cholesterol and triglycerides.  Folate also protects the Brain as well. CAUTION #1: There is some new evidence that too much Folic Acid can lead to colon cancer.  See this link for details. But, it should be added, many studies have found that Folic Acid supplementation actually lowered cancer levels.  Again, though, the safest way is always to get what you need through what you eat. CAUTION #2: You may have read that Vitamins B6 and B12 can lower homocyteine levels as well. Be careful about taking B6 and B12 supplements. These usually come in megadoses that can cause memory damage and/or exacerbate acne. See this link f for details.
7) Magnesium. Make sure you are getting enough Magnesium. Studies have shown that adequate magnesium can decrease some of the effects of Metabolic Syndrome and lower inflammation (c-Reactive Protein, a.k.a. cRP) levels which are devastating to your endothelium.  To improve erectile dysfunction and impotence, you definitely want to consider Metabolic Syndrome one of your arch-enemies. If you're eating a healthy diet, such as the Mediterranean Diet, that is so often recommended on this site, then you have little to worry about. But if you're eating like a typical Westerner, consider taking this inexpensive supplement. Magnesium is so critical that I have devoted a separate link to the subject.
8) Gingko. Gingko, like Pycnogenol, strengthens the activity of Nitric Oxide Synthase (NOS), making it a viable erectile dysfunction supplement.  Furthermore, animal studies have shown that Gingko relaxes in a dose-dependent fashion arteries, including those all-important ones supplying blood to the penis. Direct evidence that Gingko improves erectile dysfunction and impotence in a significant way is still lacking, but any herb that increases Nitric Oxide will help males struggling in this area. (This is an herb can be purchased inexpensively even in places like Wal Mart.) NOTE: Gingko Biloba is often tauted as improving erections in men with erectile dysfunction that had resulted from taking antidepressants. However, the studies have actually shown mixed results in this area. CAUTION: Care should be exercised with this supplement as Gingko thins the blood and has several drug interactions including NSAIDs and anticoagulants.<.
9) Tongkat Ali/Eurycoma Longifolia Jack.&. A libido enhancer worth mentioning because it has done well in studies on rats and because it is frequently in ex.

A libido enhancer worth mentioning because it has done well in studies on rats and because it is frequently in ex. A libido enhancer worth mentioning because it has done well in studies on rats and because it is frequently in expensive supplement preparations in health food and nutritional stores. No human studies have been done to date from what I have read, except for one that shows an increase in muscle mass . And, unfortunately, the animal studies were all conducted by one researcher.
10) Tribulis Terristris This is much-hyped in nutritional stores and bodybuilding sites as a testosterone booster. The truth is that it has a few animal studies behind it in this area but little else. Tribulis works on testosterone by increasing Leutinizing Hormone, but this has a muted effect the older a guy gets. However, Tribulis is an old friend and a lot of guys swear by it. The reason is that Trib is very likely a jack-of-all trades. We cover that here in a link on Super Sexual Herbs. .
11) Yohimbe. . One of the ways this herb seems to work is by increasing blood pressure. That’s the last thing anyone, especially those over 40, needs. So, yes, this can improve erectile dysfunction and impotence in the short term. However, it is probably dangerous to your long term health.
12) Chrysin. Estrogen can crowd out testosterone and so an estrogen inhibitor can boost testosterone. 6-OXO was recently banned by the FDA, leaving Chrysin, which is a questionable estrogen-inhibitors at best. For a more detailled look, read this link on Estrogen. .
13) Saw Palmetto/Pygeum/Stinging Nettle. All three of these herbs have a solid and generally safe track records and all three are known for their ability to block the enzyme that conversts regulard testosterone into DHT, one of the male androgens infamous for causing hair loss and enlargening the prostate. This is exactly how the hair restoration drug Propecia (formerly called Proscar) works, i.e. by blocking this same enzyme. But here is what your doctor and pharmacist will not tell you: Propecia can result in estrogen-like symptoms including enlarged male "breasts", loss of sex drive, decreased semen volume, erectile difficulties and so on. Saw Palmetto, which is the "natural" equivalent of Proscar produces these same symptoms in a certain percentage of men. Pygeum and Stinging Nettle also block this same enzyme and thus, to one degree or another, probably produce these estrogen effects. Bottom line: these herbs are simply not worth the risk. Start wearing a hat if you're that sensitive about your scalp.
