The free acid form of HMB (BetaTOR) is available in commercially produced capsules similar to that of CaHMB.  Therefore this study was conducted to compare the pharmacokinetics of HMB free acid (BetaTOR) with CaHMB when both were administered in commercially manufactured capsule form.  The results of this study demonstrated that when the capsule delivery form was used for both the HMB free acid (BetaTOR) and CaHMB, plasma HMB levels were greater and peaked earlier, and HMB clearance from the plasma was greater with HMB in the free acid form.  This advantage allows athletes to better gauge the delivery timing of HMB intake in relation to exercise bouts.
