An erection is a very complex process that involves the cardiovascular system, the CNS, hormones, etc. So coming up with a “cure” is not a simple thing as the Big Pharma companies have found out. That said, cures are certainly not impossible and a number of men on the Peak Testosterone Forum have enjoyed remarkable success. On this page I’ve documented some of the best ones that seem to match well with the current research.
And the beautiful about these cures is that they are natural or almost entirely natural. You’ll see that the majority of the solutions below are using foods and very basic supplements for the most part. So if you can solved your erectile dysfunction without resorting to pharmaceuticals, this is something definitely worth considering in my opinion. Sure, it’s easy to pop a pill, but lets take the PDE5 inhibitors: they affect other PDE systems in the eye, brain, ear and stomach. Can you really say for sure that these will not affect your long term health? (For more information, see my page on PDE5 Inhibitor Links.
So, again, check out the Forum-Posted Natural Cures for Erectile Dysfunction below.
NOTE: No, these will not work for all men. And, yes, you should always clear it with your doctor first, especially if you have a medical condition or are on any medications.
1. Nitrates + POM Juice. High nitrate foods can provide a man 35+ years old and over with a nice alternative boost of nitric oxide. This can really make a big difference and I discuss how they dropped my blood pressure by close to 10 points in this page on Boosting Your Arterial Nitric Oxide with Higher Nitrate Foods. One of our forum posters got the idea to synergistically add another superfood, or in this case a superdrink, i.e. Pomegranate Juice.
Pomegranate juice is incredibly powerful and it has restored erections just by itself in a couple of men on the Forum. I explain all the miraculous properties in my page here: The Power of Pomegranate. So putting the two together is likely to help many men whose issues endothelial, i.e. arterial in nature. (Keep in mind that most E.D. is arterial.) And it sure worked in this man:
“I have also had trouble with my erection being slow and not as hard and even not being able to get a erection off and on for 10 years. And I got on this site a week ago and came across a good article on fixing your nitric oxide levels. So I read the information and tried their advise. In 3 days I turned around my erection problem into a great big old erection as long as I need. It was very simple to do and you do it with diet, that is it. I didn’t think something so serious could be fixed so fast. I started eating foods high nitrates which your body coverts to nitric oxide to fuel your erections. I use red beets, spinach and pomegranate juice. I put V-8 juice and the red beets in the blender and blend about a minute and drink once a day. I use 1 cup V-8 to 1/2 cup of beets. It’s a miracle to me and so quick and easy. I never thought this could possible work let alone so quick and easy.” 
CAUTION: Pomegranate Juice can interact with many medications, so discuss with your doctor. Also, there is one troubling study where pomegranate negatively impacted mice in a Parkinson’s model study.  However, pomegranate has also shown neuroprotective effects, so hopefully more studywork will ensue. Just remember that a small amount of pomegranate juice goes a long ways. Also, many of our posters swear by the POM Pomegranate Juice brand. (I have no affiliation.)
2. Exercise, an Increase in Calories + Citrulline/Arginine. I have a few cautions about this poster’s protocol, but it is very interesting nonetheless. The key points here are that the poster had gone too low in calories, which can lower testosterone and thyroid function along with negatively impacting erectile strength. So adding in the calories may have been all this guy needed to do as you’ll see below. However, he is doing a lot of lifestyle changes anyway, because walnuts, POM and brown rice all increase nitric oxide! In addition, exercise increases nitric oxide for several hours and, if you do it with enough intensity and duration, it raise baseline NO levels as well. (Don’t overtrain though!) So check out his protocol below.
“DIET/SUPPLEMENTS: I cut back my L-arginine in the morning from 5g to 2g and upped my L-citrulline from 1g to 2g (1g dose at a time twice daily) Added powered cacao to my morning shake. I moved drinking the POM in the morning instead of grape juice. Started eating TONS more in food volume (I’m skinny and was averaging less than 2000 cals/day. Now I’m forcing myself to eat closer to 3000 even if I’m not hungry). The major foods added were 4 eggs daily (2 morning/2 evening hardboiled) and 1 cup (prior to cooking) organic brown rice split between lunch and dinner. I’m also eating a few Walnut and Brazil Nuts daily (usually in the evening). ”
“RESULTS: 4 days into the modified routine, I can now get a 95% erection in about 3 minutes. It does soften a bit to maybe 80% after about 5 minutes and I’m not able to get it back to the initial hardness. I’m so encouraged with the results so far!” 
Now my caution with what he did has to do with citrulline and arginine. Citrulline is quite new, relatively speaking, and I think caution is in order when it comes to long term use. Many men have used it on the forum without any side effects that I know of. However, long term effects is another story.
Arginine is definitely not something I would recommend: it likely increases outbreaks of all herpes viruses, including Epstein-Barr, HSV and HPV. I have gotten a shingles outbreak on my back taking Arginine for example. See my page on Herpes and Arginine for some more details.
NOTE: One thing that can really help almost any man 35+ is to clean out his arteries. As I mentioned, most begin to lose their baseline arterial nitric oxide due to arterial plaque buildup and the ensuing damage to the lining of their arteries. If you clear that plaque out, you can get increased blood flow and nitric oxide. For more information, read my pages on How to Clear Your Arteries . And another reason to do this is that, if you do have plaque, it can go rapidly downhill and we all know where that leads: angina, stroke, heart attack and the unmentionable in some cases. And men with erectile dysfunction typically have plaque.
4. Garlic + Vitamin C. Both garlic and Vitamin C have some evidence for artery protection and for increasing blood flow. However, what is interesting is that the combined effect of using both of these is GREATER than the sum of the two together. Somehow they create powerful synergies, something I document in my page on Garlic, Vitamin C and Erectile Dysfunction. And so it is no surprise that some men on the Forum have reported success using this combination. Look at the glowing praise of this poster (who had likely damaged his endothelium from marijuana usage):
“Hello. I’m 38 an healthy. I smoke weed an cigs. I have had problems with erections since I was 35. Some days good some days bad. Tried just about everything to help my erection. Nothing really helped. I till now I am a new man! Like I’m in my 20s! I started taking vitamin c about 2,000 to 4,000 milligrams a day. Saw a huge difference in erection! That was great! But I just found a breakthrough! Vitamin c works really well for erection, but take vitamin c with garlic an omg hard one like your 20. Rock hard. I was researching vitamin c when I stumbled upon an article. About researchers giving men in there 50s vitamin c with garlic. And it boosts nitric oxide by 300%!!! So I tried it an this us it. This is the combo that will fix you. It fixed me. I started taking both about a week ago. An I haven’t been this happy for long time. It works so well that I don’t think I could get this hard when I was 16!!”
4. Low Fat Diet + 2 mg Cialis + High Nitrate Foods. This has been my formula to eliminate my erectile dysfunction. Basically, a low fat diet (10-15% fat calories) coupled with good foods and a small dosage of Cialis has going strong even though I am about to turn 55. Now, to be honest, I don’t really want to be quite that low fat. I love dark chocolate and nuts for example. If you put me in a room with a bag of train mix, I might not come out the winner. However, I have learned time and time again that I cannot consume any significant amount of fat. People like to talk about “healthy fats.” But I can only tell that for me, they just slow down my blood flow.
By the way, this practice has apparently paid off as I had a completely plaque-free Heart Scan. You can read about it in my page called My Recent Heart Scan Results for more information. (I am also on HRT, i.e. testosterone therapy: subQ cypionate 50 mg twice per week.)
5. ZMA + Citrulline. Again, I recommend using supplements as a short term solution. However, I think they can really help you troubleshoot issues and this relatively young man (in his 30’s I believe) is a great example of this. First of all, read his glowing description of what these two supplements did for him:
“The big hitters for me( proving I have also had NO problems) have been citrulline and ZMA. The ZMA has helped me have a perfect sleep when taken at the right time as well as supplying me with a small amount of zinc. The citrulline I have just been taking once a day in the morning on an empty stomach (about 5 g). The combination have resulted in (wake me up) rock hard erections everyday which I though were gone forever. It doesn’t really matter too much if I have exercised that day or not but it is also fantastic for gym work also…which in turn boosts your NO etc etc ” 
Notice that he commented that ZMA – a combination of zinc, magnesium and a B vitamin – greatly helped his sleep. This is probably due to the increased magneisum, which is known for improving sleep in many men. And magnesium deficiences are quite common, due to soil depletion and poor diet. The citrulline, of course, helped him via a completely different mechanism: it increases arterial nitric oxide. This is very interesting considering that this is a guy less than 40 and around half of even young guys have significant arteriosclerosis according to a number of studies. In other words, young men very often now need an nitric oxide boost due to the ravages of a Western lifestyle.
6. Just Vitamin C. One poster completely restored his morning and daytime erections just by taking Vitamin C. Unfortunately, he does not say how much he took, but most guys are in the 500 mg two or three times per day category. This is what I call a nutraceutical solution, i.e. a natural food, drink, supplement or herb that solves a medical condition or significantly improves health. And straight Vitamin C does that for many men, since it lowers “stress reactivity”, i.e. keeps cortisol from rising too high and Vitamin C Increases Nitric Oxide as well.
CAUTION: Dr. Blaylock recommends taking this on an empty stomach as it can increase iron absorption. You want to take one of the “Ester-C” forms as straight ascorbic acid is quite acidic.
“So I started buying different things that I thought would help. I first started taking the generic sex pills you buy at gas stations but found out quickly they are dangerous. So then I went natural. Tried l arginine that kinda worked I guess but not much. Then I tried citulline an not a big breakthrough. And many other things. My heath is fine, I just figured it was stress or maybe libido but I really didn’t think that was the problem. So I pretty much gave up an figured my sex days were done. Then one day the wife bought some vitamin c supplements, not for my erections but because she didn’t think we got enough vitamin c through our diets. So I started taking them everyday. No big deal. Then the 3rd day of taking vitamin c I woke up an had morning wood! I haven’t woke up with wood for years! Then It kept happening every morning. I mean raging hardons like when I was 18. I couldn’t believe it. Then I started making love to the wife. An was getting hard as a rock erections! I couldn’t believe it! Even she was like what’s going on. So I started thinking what have I been eating or taking that different? So then I remembered it was vitamin c!” 
7. Just Pomegranate Juice. Some guys on the forum have raved about POM pomegranate juice and just adding that to their daily regimen has made the difference. Check out what this young guy wrote:
“Yes, I started noticing ED issues after drinking a couple years ago, then it started creeping into non-drinking sexual sessions, then of course it really wracked my mind and confidence which just made things worse. POM was the first supplement that ever worked for me for ED. I tried a lot of the supplements you see on the Internet (Ginseng, Tribulus, Horny Goat Weed, Icariin, etc) and none of them produced any benefit. I already knew that Viagra/Cialis were effective for me because I tried them when I was younger a couple times as an experiment. Since then, I can tentatively say that pycnogenol and high nitrate meals (arugula/spinach salad) seem to be effective as well. I think Aged Garlic has helped too but I have not tested it alone to know for sure.” 
NOTE: We other more pharmaceutical-based cures. For example, one senior man used a combination of Citrulline, Arginine, Cialis + Doxazosin, alpha blocker, to get his erections back.  Again, I’m trying to give more natural solutions in this thread.
