As per the clinical study on 50 subjects, CurQfen has 45-fold free curcuminoids bioavailability as compared to the total absorption of 1000 mg single dose of unformulated curcuminoids 95%, when performed a triple quadruple-electrospray ionisation tandem mass spectrometric study (Kumar et al., 2016). When compare the bioavailability of total curcuminoids as the sum of free and conjugated curcuminoids with respect to the respective curcuminoids upon a single dose of 1000 mg unformulated curcuminoids 95%, it is 270-fold bioavailable.
