Summary of mass of mannitol and lactulose excreted per hour after capsule and liquid formulation; note that, after capsule formulation, the mannitol excretion lags significantly behind excretion after liquid formula, consistent with the delivery of the sugars to the absorbing small intestine or colon. While the data from liquid formulation suggest greater absorption earlier, this may simply reflect the relative amount of mannitol available for absorption from the liquid formulation compared to the capsule.
