Hi Tom
I just checked out Bio-Kult and as I thought it contains strains which break down lactose. I am lactose intolerant and have zero problems with it. I am also on anti-candida and the bio-kult pills are so tiny they must have a negligible amount of soy - where did you see that soy was included? See this link http://www.bio-kult.com/bkfaq_home.php. Hope this helps. But then again if you are allergic rather than intolerant then probably not for you.
