One widely used additive is magnesium stearate, it has many uses, it can be used as a filler, a bulking agent, a flow agent & as a anti-frictional agent. There are studies & research that show some commonly used supplement additives affect the disintegration time (1). Other research indicates that specific additives may be immunosuppressive in some people (2).
If there is any doubt or questions on the safety of such additives we think they should not be used, thats exactly what we do, we are proud of it & we hope you are too!
We don't use talcum powder, titanium dioxide, magnesium stearate or any other stearates in our supplements, we aim to make all our supplements additive free. Where a filler is indispensable we will only ever use a nutritional ingredient, organic rice flour, natural & healthy.
