Available in foods such as yogurt and kefir (a fermented milk drink) as well as in dietary supplements, probiotics are generally defined as live microorganisms (bacteria or yeast) that help maintain a healthy balance of bacteria in the digestive tract. This is especially important because nearly three-quarters of your immune system is located in your digestive tract, so when that balance is upset, your health may suffer as a result.

Ideally, there should be a balance of approximately 80% good bacteria and 20% percent harmful bacteria in your intestines, but factors such as poor diet, stress, and illness can often upset that balance. Recent studies have shown that taking a daily probiotic supplement may help maintain a healthy bacterial balance in your digestive tract.
