"Just what are probiotics and why are they so good for you? Probiotics are "viable microorganisms" that can confer lots and lots of health benefits if they reach your intestine while they're alive. You may have heard them described as "friendly bacteria." These bacteria aren't just friendly, they're flat-out adorable.. They're currently being touted as a miracle cure for a whole host of ailments, whether you're dealing with acne, depression, diarrhea, or even cancer. Even if you're not dealing with any of those ailments, you want to make sure your GI tract is flourishing, and pre probiotics are necessary to maintaining your digestion—which is, in turn, key to your general health (not to mention pooping)."
