Everyone has experienced the numbing effect that occurs in the legs and
feet after sitting too long in one position. The same situation applies
to the shaft and head of the penis. Sitting for long periods of time,
cycling, obesity and restrictive clothing can all reduce the circulation
to the penis, leading to lost sensation which may not immediately return
even after the pressure is removed. Stimulating circulatory health with
vitamin C, which is necessary for building blood cells, can help to
increase blood flow to the area. In addition, vitamin B5 and L-arginine
work together to provide the oxygenation needed for skin and nerve cell
health.>> http://www.supplementsauthority.com/ketone-slim-xt-review/
