Plasma HCA concentrations over time in subjects having consumed 2 g HCA.
The concentrations were adjusted for the mass difference between the purified HCA ethylenediamine salt used in standards (molecular weight 268 g/mol) and the HCA in the capsules ingested (molecular weight 5 208 g/mol). The time points for subject 2 were different from that of other subjects because of delays in blood sample collections.
