1. Introduction
It is a DC grade of magnesium citrate and granular style special for capsule and tablet usage. The difference between nonahyrate granular and anhydrous granular is loss on drying.
The LOD for nonahydrate granular is no more than 29%. However, it is no more than 2% for anhydrous granular.
Also, some one call this ingrdient “Trimagnesium citrate granular” or “trimagensium dicitrate granular”
2. Character of magnesium citrate granular
It is manufactured by drying granulation method. No carrier.
It is a irregular, ordorless, white granular.
