Hoodia Chaser is a kind of tincture that is added to water and taken before meals. It is reputed to suppress appetite and therefore aid in weight loss. The idea of liquid ingestion over tablet form is that it is absorbed into the bloodstream quicker than tablets. The faster it goes in the earlier it starts to work.
Hoodia Chaser, like other hoodia products, works on the brain. It fools the brain into thinking that there is enough blood sugar so it literally closes down the hunger feeling that you get when you have not eaten for some time. By doing this it stops you eating or overeating.
