Probiotics
I am pretty fussy about my probiotics and would rather spend a little extra to get a good probiotic. I would never buy a probiotic with a binder- always get one that is in capsule form. You can even open these up and mix with a little water if you want it to take affect immediately. I would also get one that is stored in the fridge so that the cultures are live. I usually use RAW by garden of Life and have great results with it. You can get it at Super Supplements or other supplement stores. Make sure you get one that breaks down in your stomach and will last as it travels thru your intestinal tract rather than one that doesn't break down until it hits your small intestine. I think they work better and cover more area.
Good luck!
I use Garden Of Life. Great stuff. It's expensive, but it's the only stuff that I have seen do a real job so far. I didn't notice much difference with the other brands I've tried (and I eat yogurt every day).
I get the RAW stuff that has to be refrigerated. It rocks. I take a lot less of it, the diarrhea stops immediately, and I have very little gas.
Then I take Jarro probiotics every day (the Garden of Life once a week). Jarro is shelf stable (doesn't require refrigeration).
Look for a product that gives you the most strains, and look for a product that gives you the most live cultures per dose.
Also, eating yogurt every day helps also.
