The only probiotic some insurance companies cover is VSL#3DS. I checked with my insurance company before I started taking it. It has to be the DS with 900 billion vs VSL#3 that has 450 billion.
It doesn't have the probiotic in it that Jan is referring to so I bought it from Amazon.com for $14, 90 - 5 billion capsules. SO I am taking 2 a day. Thanks everyone for confirming the dosage.
