Probiotics are beneficial microorganisms (usually friendly bacteria) that promote health. However, the term "beneficial microorganisms" is common in agriculture and gardening whereas “probiotics” refer to supplements of beneficial microorganisms for humans.
Probiotics often provide extraordinary benefits because these microorganisms are absolutely essential for the healthy function of the immune system, optimal brain function, body weight, blood sugar regulation, and more, but exposures to toxins and poor diet destroy these microbes.
Manufacturers create various formulations of probiotics to improve the flora of the intestinal tract, mouth, skin, and vagina. For most people, Probiotic 55, Children’s Probiotic, Lateroflora, and the probiotics contained in the Greens Pak varieties appear most effective and reasonably priced.
