Sorry, this maybe a kinda of naive question.
I don't know the difference between Align and VSL3.
When I searched "Probiotics" on Wiki, I found Align but not VSL3. Are they totally different or simliar? Is it OK to take both of them or just try one?
I saw some people are taking VSL3 while others are on Align. I do not know how to choose.
Also, these Align or VSL3 doesn't need prescription, right?
Thanks
