I have always suffered with digestion issues. I have tried probiotics in the past, but have never found any relief. Since I have been taking Dr. Picks Probiotic daily, I have found I have more energy, less fatigue mid afternoon, and what is the best-less digestive issues! I would highly recommend this product!
