Niacin will make your face flush - go red and hot.Yes...and there are tons of different forms of niacin....so nutritional yeast or brewers yeast will work fine, because they both supply niacin...and help the problem not come back. When the problem is corrected get all flock...it has niacin in it, but I supply with extra so they are getting the exact right amount( I just sprinkle it on the food). Yes you do need b-complex with out flush free niacin. Which I see you have gotten so good job!
I have no idea what flush free really means....@Miss lydia?
