Bests & Worsts Reviews from Amazon

So far I've used three (3) bottles of this product. I switched from Jarrow Saccharomyces Boulardii because NOW Foods offered the same potency with a lower price. The first bottle seemed okay, but I did notice it didn't seem quite as active; or potent as Jarrow. The subsequent two bottles I've been somewhat disappointed in. They haven't seemed to have the same activity (or potency) as the first, and I can definitely say they have not been as active as Jarrow's. Now, this could be due to the fact that I've had these shipped in the middle of summer, and the heat is having a negative effect. They have not been shipped with and ice or cooler pack. However, Jarrow's didn't ship with a cooler pack either, and they seemed active anytime I had them shipped to me. Bottom line - I'm going to move back to Jarrow for this product. Jarrow may cost a bit more, but I can be certain that the product will be active and potent, and do what it's supposed to.
