What the sources say
FDA approved Ace-K as a general-purpose sweetener after reviewing more than 90 studies, including reproductive effects; it's often combined with other sweeteners in diet drinks. A peer-reviewed review rates it acceptable in pregnancy within the acceptable daily intake (ADI) and notes it is detectable in breast milk at levels far below the ADI.
