Is CurQfen® food-grade? And what about its solubility?

CurQfen® is food-grade and suitable for powder beverages (sachets, stick packs, Golden milk), protein bars, protein supplements, gummies, yogurt, instant soup powders, chocolates, etc at 100 to 200 mg/serving size without taste issues. CurQfen® is the only bioavailable formulation of CurQfen® that has been used as a functional food ingredient and the bioavailability from the food matrix has been confirmed on humans at 100 mg dosage/serving size (Food & Function, 2014). It is water dispersible and can dissolve completely on stirring. However, a significant settling may observe on standing the water solution. But, it is good for liquid shots and liposomes.
