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
5
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.
