Prebiotics are a special form of dietary fiber – food ingredients that stimulate the growth and/or activity of bacteria in the digestive system in ways claimed to be beneficial to health. They are responsible for ensuring that the intestines and colon maintain a healthy balance of bacteria which creates the conditions necessary for healthy digestion and nourish the good bacteria that everyone already has in their gut. When working properly your body can extract, retain, and transport the necessary nutrients, vitamins, and minerals from the foods we eat to fuel our bodies. Prebiotics supply the energy these beneficial bacteria need to keep doing their job and keep your digestive system healthy. Prebiotic powders are not affected by heat, cold, acid or time. They provide a wide range of health benefits to the otherwise healthy person. Most of these have been medically proven.
