I began using Ultra Flora Plus DF a few years prior as recommended by my wellness doctor. At the time I had IBS and then Candisis that came about from my overtreatment of Lyme. I had gotten quite sick, but Ultra Flora Plus DF had helped me so much. It wasn't super fun, but without it, it would've been so much worse. This has been the best place to buy it as the prices are great, the delivery is quick, and the customer service is top-notch.
