Plasma carnitine levels during intravenous feeding of the neonate
1979
Schiff, David | Chan, George | Seccombe, David | Hahn, Péter
During periods of intravenous alimentation, blood carnitine levels in infants fell to extremely low values. Conversely, in periods of oral alimentation, the carnitine levels rose strikingly. Thus, blood carnitine levels in infants depend largely on external sources of carnitine. When essentially no carnitine is given, the blood levels remain consistently low. This finding suggests that carnitine is being supplied exogenously from some depot or from synthesis within the liver. The higher carnitine levels are caused by such exogenous sources as expressed human milk and proprietary formulas. However, feeding nutrients that do not contain carnitine, such as soybean-based formula, leads to a fall in blood levels of total carnitine.
