Probiotics

[celeste <celestem@badgermining.co.za>]

Another question from South Africa. I have been reading through the 
archives (1996) and see that many of you guys use probiotics before, during 
and after a ride. Someone then mentioned that yogurt is a substitute for 
probiotics if they are not available.
Question 1: Are probiotics still used before, during and after rides? or os 
this out dated?
Question 2: As probiotics are unheard off here in South Africa (other than 
the vet using them and getting them from the vet for regular use is WAY out 
of my price range) can yogurt be substituted? How would it be administered 
ie. quantities and frequency?

Thanks

neat stuff!)
