Anyone take Yakult?

My husband started taking this and says it helps him. It has Lactobacillus casei shirota in little bottles of dairy drink...this product is know better in other countries where people have used it for a long time. In the past I've taken DanActive, which is probably similar, now that I think of it. DanActive has L casei immunitas, B. bulgaricus and A. thermophilus. All probiotics, of course. I don't know if one strain of L. casei is any better than any other strain.
