Thanks for your detailed reply Syl. You sound a bit similar to me only I can tolerate fructose - have you tried any probiotics yourself? I've emailed Lifespan the Aust distributor for Natren products as they don't list Lifestart 2 to see if I can get it here. I'm a bit uneasy about it as I can only tolerate a very small amount of lactose and it contains whole goat milk powder. Today I have had a not so good day - I took my food experimenting too far, had 3 tablespoons of cream and am paying for it, so I will still have to be very careful with lactose and fat. The OMX Probiotic Formula is suitable for lactose intolerant people but I agree, it contains a lot of other stuff. I'll see if I can find out how much Bifidobacterium infantis 35624 it contains. Jordy, I don't know if you can get IBS support in the states. Ethical nutrients who make it are an Australian company. Their product has to be kept cold but I have contacted them and the lactobacillus plantarum organisms stay viable for quite a while out of the fridge, here is an excerpt from their reply: "Temperature (degrees C) Time guaranteed to be above label potency 40 48 hrs 30 14 days 25 4 months 4 2 years The results show the product to be very tolerant to prolonged periods of storage and to variations in transport conditions without harming the bacteria". I would think that there must be a similar product in the US. If not, Chemistdirect.com are an Australian online pharmacy I use. They seem to be the cheapest (they have IBS support 90 caps for $49.95 Aust and it is $69.95 at my local chemist). They post overseas and say international orders are sent via Airmail with DHL Global Mail. Please allow 2-3 weeks for international Airmail delivery. Here is the link to the product on their site: http://chemistdirect.resultspage.com.au/search?w=IBS+support&view=list&search_in_description=1 I'll keep you posted on my experiment. The last 2 days I have gone up to 2 capsules to see if it affects the amount of BM's.
