Magnesium Stearate is a mineral salt often used as a flow agent in the manufacturing of dietary supplements. The substance is useful due its lubricating properties that prevent ingredients from sticking to manufacturing equipment.
Magnesium Stearate is Convenient for Supplement Manufacturers, but Questionable for Human Consumption.
Numerous studies have shown that stearic acid (one of the two components found in magnesium stearate) may be toxic.
Research shows that stearic acid may be immuno-suppressive. Stearic acid has been confirmed to suppress T-cell function (immune function) in several landmark articles which were published in Biochemistry in 1989 and in Immunology Magazine in 1990 and 1994.
In addition, stearic acid has been shown in human and animal studies to cause “programmed cell death” (apoptosis) in both heart and nerve tissue as published in both the American Journal of Medical Sciences in 1999 and the Journal of Neurochemistry in 2003.
Despite the negative research, Magnesium Stearate is still found in almost every capsule and tablet sold. Why? The manufacturer saves money and increases profits.
