I have been taking iFlora for a couple of years and it is by far the best herbal supplement I take! I haven't had common cold or flu symptoms since I have been on the product. I recently stopped taking it for 3 months in order to test my body to see if I really needed to continue taking it or not. After a month of not using iFlora I began to experience low grade headaches, body aches & pains, sniffles, lethargy, PMS and intestinal issues. I now realize just how important this particular product is for my overall health. It keeps my immune system strong, which wards off any would be bio threats. I highly recommend iFlora for Women!
