Olympian Labs Extra Strength Delayed Released Prebiotic & Probiotic offers the live bacteria of a probiotic, combined with the bacterial energy sourcing of a prebiotic to help deliver optimal digestive health. Because our intestines account for over 70% of our immune system, we cannot overlook the important connection between the health, integrity, and bacterial balance of the gut wall. This “essential ecosystem” provides an important balance between health and bacteria in the body. Therefore, it is important to focus on maintaining a healthy balance of intestinal flora with probiotics and prebiotics. Probiotics are a type of good bacteria in the intestinal tract that aid in digestion and immune functions. Prebiotics are non-digestible components of our diet that are fermented in the colon, increasing the growth of good bacteria.
