Magnesium Stearate Safe

Those who argue that magnesium stearate is unsafe are apparently wrong. Their argument is based on a 1990 study, "Molecular basis for the immunosuppressive action of stearic acid on T cells." But as Byron J. Richards points out, that study had no real bearing on the filler used in vitamin pills. He says, "Bad mouthing magnesium stearate is nothing more than a sales pitch. It is extremely irresponsible." He describes the study, which was intended to make a substance to harm T cells, and then he points out that, "You can readily see that such an experiment has absolutely nothing to do with dietary supplements. It is falsely represented as "proof" that dietary stearic acid is immune toxic – which the study does not prove at all."
