Protein Ingestion and Muscle Carnitine Uptake

The Effects of an Insulinotropic Protein-carbohydrate Beverage on L- Carnitine Absorption and Muscle Carnitine Uptake

The purpose of this study is to assess the effects of a protein-carbohydrate beverage on the absorption of an orally ingested bolus of L-carnitine, compared to flavoured water and carbohydrate-only controls, and to determine whether increasing plasma carnitine availability can impact upon insulin-stimulated muscle carnitine uptake.
