Primal Defense HAS been reformulated. It is not the same product as 8 yrs ago. If you compare the ingredients (if you have an old bottle) you will notice several strains missing. I had an old bottle and noticed Swanson has a product with the very same ingredient a LOT CHEAPER, so I've been using that. The first label is from Primal Defense, the second is Swanson's Ultra soil-based organisms.
