I believe the best Probiotic is in fermented Milk Kefir that you make yourself with Kefir Grains.
It contains from 32 to 35 different kinds of live Bacterias.
Also, it has Probiotic Yeasts and many vitamins, acids...
I cured all my indigestions and many other health problems.
To get curative effect you need to take 1 liter minimum (1/4 of Gallon) a day.
I take 1,5 liter a day (I love Kefir!) - dividing it on 3 portions. I drink it strait or as a base in Smoothies/Soups.
Morning Smoothies - all you need for breakfast!
And You will feel great!
