my experience has been this: if my defence's are a little down and im bloated or my gut is out of whack, superfood will MAKE IT WORSE, i know its supposed to be a harmless yeast, but candida patients should avoid it for the most part and juice green leafy vege's(as much as a pain in the ass as that is). so follow your instinks, stay away from all yeast, i have a bottle i just bought that im sending back.
