Live culture yogurt

How can you tell if yogurt has a live culture? I was told to eat some
yogurt and some probiotic pills to help with diarrhea after antibiotics by
the pharmasist. He also steered me to some OTC anti-diarrhea meds.

How can you tell if the yogurt is live culture? Will it say so on the
package? None did at the grocery so i tried one at random. Tasted good but
I suspect it was dead. Didn't squirm around a bit. <g>
