Lactobacillus acidophilus, or L. acidophilus, is the most commonly used probiotic, according to the University of Maryland Medical Center. It is especially beneficial for intestinal health because it breaks down foods to create substances such as lactic acid. This creates an environment that is not suitable for harmful bacteria. L. acidophilus is also beneficial for regular digestion, constipation, lactose intolerance symptoms and enhanced immunity. Lactobacillus bulgaricus and Streptococcus thermophilus are two bacterial cultures seen in most yogurts on the market. Some also include L. acidophilus.
