Amongst the many effective methods to help improve your ability to gain an erection, the male enhancement methods presented in this article are probably the easiest and safest to implement. They are all 100% natural, have some scientific rationale based on current research findings, and are (most importantly) quite safe to implement.
Method 1: Vitamin D3
In the scientific literature, vitamin D deficiency has been clearly linked to stiffness of the arteries and a deterioration of vascular function.   This suggests that it may be beneficial to erectile dysfunction cases – in which vascular dysfunction is the critical biological risk factor.
All in all, these are great reasons to take vitamin D3 as a supplement – do it!
Method 2: All B Vitamins
Every single B vitamin has been shown to be beneficial in improving erectile dysfunction. Deficiencies in B vitamins are associated with increased levels of homocysteine, which is a harmful chemical (derived from amino acid breakdown in the body) that damages endothelial cells (little cells that line our blood vessels) and diminishes vascular health.
Vitamin B supplementation helps to keep your blood vessels healthy, helps to combat stress, and is a potent method of preventing or protecting against developing erection problems. All the B vitamins are beneficial, but the most important ones for erectile dysfunction are Vitamin B6, B9 and B12. 
Vitamin B is easy to get, relatively inexpensive, combats stress, helps protect the cardiovascular system and has a whole bunch of other potent benefits – do it!
Method 3: Vitamin E
Damage to tissues and cells due to free radicals (oxidative damage/stress) has been linked to poor erectile functioning.   The reason for this is thought to be because oxidative stress impairs cells’ ability to absorb nitric oxide (very important for dilating blood vessels and encouraging blood flow to the penis), as well as damaging the walls of blood vessels themselves.
Vitamin E is one of the body’s most important antioxidants – it is massively important in protecting the body from oxidative damage, particularly oxidative damage to our blood vessels. Furthermore, studies have shown that supplementing with vitamin E enhances the functioning of our blood vessels, reduce free radical stress and increases the production of nitric oxide amongst other benefits.
What more need be said? Vitamin E is a great way to rise up against free radical damage – do it!
Method 4: Exercise
In short, exercise is good for erections.
Why? It stimulates nitric oxide release in the body, which improves erectile dysfunction instantly! Studies have shown time and again that exercise is great at providing cardiovascular protection, improving erectile function and boosting sexual response.  
Exercise – do it!
Always consult with your favorite healthcare professional before you take biologically effective supplements. In the case of exercise, start slowly and carefully and build yourself up. Even better, consult with someone who can assess your needs and risks just to make sure everything is fine. The above four methods are powerful, simple, effective and inexpensive. After using them for 3 – 6 months you should substantially positive results.
All the best
