Hi, I have used many different types of pro-biotics from powders to liquids and have found the best way to maintain healthy levels of the good guys is through using kefir. Many people say that dairy milk has to be used but I find that fresh almond milk with some coconut juice works realy well. The culture loves it, seemed to me like it was growing although I did not weight it to find out. I have been leaving the coconut juice out lately as have bought to many rotten ones, instead I put in a dessertspoon of honey; it works but not as well.
I got my kefir grains off a guy called Dom in Adelaide who is well known for his knowledge on kefir (Gabriel Cousens mentions him in his book Lean Green Cuisine). There is a kefir network through Harold Tietze's website. I think it is www.wise-mens-web.com
Dom's site is

Hope this helps.
