The human gut is colonized by several beneficial bacterial species and these microbes provide multiple benefits to us by synthesizing vitamins and fatty acids. A prebiotic substrate promotes the growth of beneficial gut microbes. A few prebiotic substrates are inulin, oligofructose, and fructooligosaccharides. Prebiotics are a mixture of natural fiber and other growth-promoting substances such as oligosaccharides. They selectively favor the growth of beneficial gut bacteria.Interestingly, human digestive enzymes cannot digest prebiotics and thus, the prebiotic substrates are available to gut microbes and help feed the good bacteria in the body. In fact, the fibers found in bananas, garlic, and leeks can also act as a prebiotic.

Due to several health benefits of prebiotics, they are now increasingly being used by people. A list of some of the best prebiotic supplements available in the market is presented below:

Dr. Formulated Organic Fiber
