Vitamin B12 can be found only in the products of animal origin. That is, the greatest amount of this vitamin is available in by-products (liver, kidneys, and heart). The other vitamin B12 rich foods include cheese, seafood (crabs, salmon fish, and sardines), meat, and poultry. Vitamin B12 deficiency declares itself by diarrhea, decreased appetite, tingling tongue, burning tongue, low stomach acid, altered skin sensation, and impairment of sensation in the extremity muscles.
In addition to getting helpful nutrients from your diet, you can also consider supplementing. Many of these are also on my list of top five supplements to increase sex drive, so they’re helpful for overall sexual health. It’s a good idea to check in with a practitioner, particularly one with knowledge of your individual health issues and medications, before taking anything. Here are some I recommend:
Can one of the B vitamins actually improve erectile dysfunction? The research makes a strong case that Niacin, a.k.a. Vitamin B3, does indeed do just that for a big percentage of men. Of course, this is a inexpensive help to erectile issues, as high niacin foods and supplements are cheap and readily available. Below I summarize the most prominent human evidence to date that shows which men will likely benefit and why:
Kegel exercises benefits a lot of men. In particular, they also help in strengthening the bulbocavernosus muscle. This very important muscle performs three types of roles. One it allows the penis to grow and be engorged with blood during erection. Second, it pumps while ejaculation, and third, it helps in emptying the urethra right after urination.
A conflicting study of 22 subjects found that a 100mg daily dose of yohimbine for 30 days did not significantly improve penile rigidity. Three subjects experienced a notable increase in penile rigidity and twelve subject experience a partial increase in rigidity.  These findings do not completely discount the use of yohimbine to treat erectile dysfunction, but do suggest the compound's effects, even at very high dosages, will cause varying responses across a similar population.
When stimulated by the nerves, the spongy tissue arranges itself in such a way that more blood can be stored in the penis. The veins running through the outer sheath of the penis then compress which stops the blood from leaving the penis. As the blood is stopped from flowing out, the penis fills with blood and stretches within the outer casing, giving an erection.
Unfortunately, many of the same factors that brought the Italian Renaissance to an end—among them corruption, wars, and a widespread backlash over secularism and indulgence (leading to the “Bonfire of the Vanities”)—also terminated the “rebirth” in Spain. Chasing heresies became a sport that led to the resurrection of the Inquisition, which unlike its prior appearances operated completely under royal authority, rather than the aegis of the church.
In fact, one common reason many younger men visit their doctor is to get erectile dysfunction medication. Often, men with erectile dysfunction suffer with diabetes or heart disease, or may be sedentary or obese, but they don’t realize the impact of these health conditions on sexual function. Along with erectile dysfunction treatment, the doctor may recommend managing the illness, being more physically active, or losing weight.
Erectile problems can sometimes be linked to cardiovascular issues. If your heart isn't in full health, your sex life maybe suffering as result. Men who suffer with moderate to severe erection problems have significantly lower levels of folic acid than guys without the issue. The B vitamin has been shown to work with nitric oxide which would explain why an absence of it would lead to problems in the manhood. This seems to help with erectile dysfunction more than some medications. Treatment with folic acid resulted in men having an increase in their erectile strength.
The truth is medication or psychosexual counselling are the first treatments a doctor will suggest because they’ve been proven to work. If a doctor has approved a medication for you then it’s safe. If you would still like to see if herbal supplements work for you, then there is a list below of supplements thought to work for erectile dysfunction. Just before you invest your money in them, remember they aren’t proven to work:
Taking zinc in supplement form is just one of many treatments for those looking for help with ED. Many men use supplements either to replace prescription medications like Viagra and Cialis, or to enhance the effectiveness of these medications. Some other natural supplements aimed at relieving ED symptoms include Korean red ginseng, L-Arginine, carnitine, and DHEA.
