Dr. Mercola Complete Probiotics Can Help You Take Control of Your Gut. Our Complete Probiotics floods your body with 10 strains of exceptional beneficial bacteria, including long-lasting super-strain, L. acidophilus DDS-1, to help balance your microbiome.* To enhance the potent acid- and bile-resistance of our formula, patented delayed-release capsules (DRcaps) are used to deliver an extra layer of protection against harsh stomach acids so the probiotics reach your small intestine – where they work best. Because our Complete Probiotics (70 and 100 Billion CFU) do not require refrigeration, they're both convenient and perfect for traveling, helping to keep your GI tract in optimal shape while away.* *Statements regarding dietary supplements have not been evaluated by the FDA and are not intended to diagnose, treat, cure, or prevent any disease or health condition.”
