Has anyone here tried EpiCor for either CFS and/or sinus problems? It is an immune system modulator that helps regulate your body's natural immune defenses. It was discovered that the workers who worked in the production department, making this brewers yeast product for animal feed, never got sick or needed to be hospitalized for anything. It was actually the manufacturer's insurance company that brought this to their attention. PH sell this product (as do other companies) and I am thinking of purchasing it to see if it will help with my sinus problems (and maybe my CFS). Has anyone used this and if so, what were the results? Good or bad, I'd love to hear from you.
