Due to its simplicity, direct compression has become the preferred tableting process of the food supplement industry. Especially in single-ingredient tablets of potassium, calcium and magnesium, the choice of the right direct compression mineral is highly critical, since it must combine high compressibility with excellent flowability and elasticity of the powder. PURACAL DC (calcium lactate) and GLUCONAL K-G (potassium gluconate) are examples of PURAC minerals that are very suitable for direct compression because of their good flowability combined with their excellent compressibility and particle elasticity characteristics.
