Query: My opinion...

I have bought this probiotic...but haven't taken it yet. Natures Way is NOT listed in the probiotics currently covered by ConsumerLabs.I have used another less expensive Nature's Way probiotic.I do think probiotics work...but I think you need to take them for a few weeks to a month to see some real lasting effects. It also helps to avoid too much sugar or fruit and maybe even grains...due to yeast issues.It is difficult to know which probiotic to buy and which is effective....and cost-effective. I tend to go with the enteric coated type....though some species of bacteria can survive stomach acid.Will be looking for a cost-effective probiotic for maintenance use.This particular probiotic MIGHT be a good one to start with....depending on how difficult your gastro issues are.
