Personal experience and objective data tell me that Roche tablets are best, and that there are no inconsistencies between the brand and generic
wafers. The
wafers have little room for error, as they are very rapidly absorbed. Binders and fillers in tablets are all subject to variation (depending on the manufacturer), which likely affects absorption, and subsequently, onset of action, AUC Max, BA and BE.
One day, I intend to write a post with my objective findings on this subject.
