I am using a multivitamin tablet by the name " verghery gold" advised by a doctor . it makes me feel good. but no effect on sex life, suggest altern?

Expectations : I am glad you found a vitamin that you like. It's important to have realistic expectations though. A vitamin it's not likely to change your sex life in anyway whatsoever.

That is normal: Multivitamins are generally worthless, which is why the FDA does not regulate them. But they can be harmful, and you should stop them. Save your money and exercise more, which may also help your sex life. If you need support for your sex life, see a Doctor for specific treatment.
