Digestive Advantage Lactose Defense Formula contains 2 powerful ingredients to support your digestive health: BC30 probiotic to help restore the natural balance of good bacteria within your intestinal tract, and Lactase to help with the digestion of lactose commonly present in dairy foods. If not broken down, lactose can cause gas, bloating, and occasional diarrhea. The unique patented daily probiotic in Digestive Advantage Lactose Defense Formula, BC30, is protected by a protein shell which allows it to survive through the harsh conditions of your stomach to reach the intestines where you need it most. It's the probiotic supplement that survives stomach acid 100x better than yogurt and leading probiotics.
