Notes for this study:
Over 24 weeks, healthy male subjects (nonvegetarian) consumed 80g of carbohydrates with or without 2g L-carnitine-L-Tartrate. The carnitine group had 21% higher carnitine levels, showed a greater percentage of fat burning at 50% intensity exercise, and had a better energy production (80% intensity) and performance relative to control (+11%) and thought to be secondary to bioenergetic changes.
