Probiotics are those good-for-you bacteria and yeast that are normally present in your body but can be disrupted by things like antibiotics or even
traveling or getting an infection. So the way probiotics work is they really maintain the integrity of your digestive tract.
They do that in a couple of ways. They help maintain the lining of your intestine so that things that you don't want getting into your bloodstream don't
go through that leaky lining. And they also help actually literally digest some of your nutrients. So they're very important and we really
want to maintain that balance of good bacteria in our gut. You can get probiotics in your food or you can take a supplement.

about the ideal dosage of supplements, so I don't really recommend just going out and taking one for no apparent reason.
Talk to your doctor if you feel you need one, but getting it in food, I think, is a great idea for everyone. And it's present in things like yogurt or kefir, sauerkraut,
miso. A lot of fermented foods do contain probiotics. [AUDIO LOGO]
