L-Carnitine
Quaternary ammonium metabolite
A carrier molecule required to move long-chain fatty acids into the mitochondria for oxidation.
How it works
Forms acylcarnitines that shuttle fatty acids across the inner mitochondrial membrane, and buffers the acyl-CoA to CoA ratio during high metabolic flux.
What research has shown
Trials report improved exercise recovery markers and modest fat oxidation effects; effect size depends heavily on baseline carnitine status.
