Inner Health Plus Immunity Booster for Adults support the body's overall ell-being through support stomach and intestinal bacteria. To build a solid foundation for your health, a good place to start is where good health begins - in your digestive tract. Many pathogens and toxins enter into your body through your skin, lungs, even your mucous membranes! However, the largest source of toxins and microbial agents come from an area that most people would not expect - your digestive system. It may seem strange to think of the digestive tract as an external organ, but that is precisely what it is. The digestive tract has a very large surface area that comes into direct contact with our external environment, whilst providing a physical barrier to protect our internal organs from infection-causing bacteria, parasites and viruses. If our digestive system was to be stretched out, its surface area would be roughly equal to the size of a football field! This large surface area presents a defensive challenge and must be policed with many immune cells to protect you against illness. As it is so closely intertwined with the immune system, the digestive tract is recognised as a very active immune centre, and is thought to contain a whopping 70% of the body's immune system.
