Vitamins and Supplements for Erections | Does L-arginine Work for ED?

In this video, I talk about vitamins and supplements for erections. I'm going to look specifically at what the science and data say about L-arginine, which is an amino acid precursor for the production of nitric oxide. Is L-arginine effective for erectile dysfunction (ED) - fact or fiction?

The bottom line is that it does work, but you need to take an adequate dosage for it to work.
