Fuel into energy
L-carnitine carries fatty acids into your cells, where they become energy.
Less everyday fatigue
Adults given L-carnitine had better fatigue scores over 24 weeks.*
Endurance that holds up
Adults given L-carnitine kept more of their peak exercise capacity.*
* Brass et al., American Journal of Kidney Diseases (2001). Two randomized trials of about 180 adults on hemodialysis given L-carnitine by IV for 24 weeks; fatigue scores improved, and a secondary analysis showed less loss of peak exercise capacity (the main endpoint was not met). LIV's L-carnitine is given into the muscle and was not tested.
