Several people have mentioned freezing their MAF and I thought I'd read somewhere that it kills off some of the bacteria (i.e. a bad thing). Some people have mentioned that even though they froze their MAF, they still had some benefit. I wish I could remember where I read about freezing MAF! But I just googled on whether you could freeze probiotic yoghurts (assuming that MAF is a probiotic yoghurt par excellence) and found this: on this site: http://www.probiotics-help.com/probiotic-yogurt.html which doesn't say who they are or why they would know what they're talking about. However, there's loads of opinion about this on the net including this thread on a bodybuilding site which has people arguing both sides: http://www.wannabebig.com/forums/showthread.php?63542-Freezing-Yogurt-and-L.-Acidophilus So basically I haven't got a clue. I'm erring on the side of caution and not freezing my MAF. Anybody got any evidence on this?
