I take Acidophilus Plus with Live bacteria. It's six bucks (including tax). i get it at my local grocery store.
I did have some gas when I started taking it and some very erratic D. I have been taking it for over a year now no gas, no erratic D just smooth (solid) bms.
It works great for me and the gas and D did not last over a few days. I guess my body was adjusting to something new being put into it.
Good luck.
