There really aren't enough live cultures of the acidophilus in yogurts to regain balance, not to mention it better be organic, or at least RGbH Free dairy. Supplementing combination (multi-strain)probiotic capsules will be tremendously more effective. Make sure the capsules do not have anything besides the cultures. Some products use a ginger, cayenne, or vit. C proprietary blend as well, Ouch!.
