Protein Ingestion and Muscle Carnitine Uptake

Phase 1

Completed

• Conditions: Muscle, Skeletal
• Interventions: Dietary Supplement: Flavoured water + carbohydrate + protein; Dietary Supplement: Flavoured water + carbohydrate; Dietary Supplement: Flavoured water

• Registration Number: NCT02535897
• Lead Sponsor: University of Nottingham

Brief Summary

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.
