I have a Naturalpathic (sp) Dr and I have been sick since Dec 26 he prescribed Maitake D fraction to build my immune system which I think typically are a good thing to take. But it seems my immune system sucks and everytime I get sick I can't get better without antibiotics. Do any of you face the same problem or do you have any suggestions. This is getting really old. My sister lives in canada and she told me about Cold-FX so I will be trying that.
