I've got two kinds of acidophilus that don't contain "illegals". One is Swanson Acidophilus, 100 capsules, and the other is GNC Acidophilus probiotic complex 2 billion CFU (colony forming unit). However, a serving of the 24 hour yogurt is said to have way more beneficial bacteria than that of a little acidophilus pill.
I think there are some more expensive probiotic pills that you can order. You'd have to do a little searching on the internet and make sure they don't contain bifidus because it is SCD illegal.
