I've taken many probiotics to help with intestinal dysbiosis caused by candida overgrowth (I had a severe systemic case), and since taking Dr. Ohhira's Probiotics my bowel movements have started returning to normal. No other probiotic supplement has seemed to do it's job in replenishing my digestive tract with healthy, good bacteria. I've been taking these probiotics with the Inuflora, just to ensure the good bacteria has what it needs to establish colonies. If you've had candida overgrowth, like me, be sure to eliminate the candida first, then clean out your system, and then repopulate with Dr. Ohhira's, while taking immune support supplements. I'd also recommend looking into adrenal fatigue (A good book: Dr. Wilson's 21st Century Fatigue Syndrome), since candida really hits your adrenal glands pretty hard. I will continue to take Dr. Ohhira's Probiotics along with Inuflora to ensure I keep balanced. I highly recommend iHerb.com, too. Shipping is fast and their prices are the best!
