People used drugs for the treatment only. Drugs may also cause sexual dysfunction. There is very necessary that first should consult to any doctor before using any treatment. There can be side effects due to drugs. The best vitamin for male sexual health is fresh healthy diet like by Green tea, tomato, papaya, soy bean etc. Mostly person used vitamin pills for improving health. I got about a pill which is Levitra. It’s a newest drug which especially works on male sex organs and having good results. It can get online also. http://www.levitrabliss.com/
