Are there any negative side effects from "w/SRT"?
Jigsaw's w/SRT is completely phthalate-free, so there is no concern for thalate-related negative side effects from it.
Carnuba wax (which is the same wax used on cars) is another common mechanism used by companies to make a supplement sustained release. Jigsaw's w/SRT does not contain carnuba wax either.
