Safety Warning: Digestive discomfort is a relatively normal reaction to beginning a probiotic regimen, increasing dosage, or changing products. When the beneficial organisms colonize in your digestive tract, they begin working to support a balanced gut environment by producing vitamins and digestive enzymes. These byproducts (such as lactic acid and B vitamins), along with the shift in bacterial population, can cause some temporary side effects that can include bloating, gas, or even a mild laxative or constipating effect.
