One of the Dan! doctors we've seen recommends coconut kefir instead of probiotics for some of his patients who don't require or can't tolerate stronger probiotics.
Trouble is... I want to be able to BUY coconut kefir. I don't want to have to make it. You can buy cow's milk kefir in many grocery stores.
