On the other hand, the heart uses fatty acid oxidation regularly, with 50-70% of energy coming from fatty acids.[ref] Other roles of carnitine in the mitochondria: In addition to transporting long-chain fatty acids into the cell, carnitine is also involved in moving certain metabolites out of the mitochondria

Genetic variants in carnitine-related genes (SLC22A5, CPT1, CPT2) can cause disorders that affect energy production, causing issues from mild fatigue to severe dysfunction

[4] This is supported by a study of resistance-trained athletes showing that 2g per day of l-carnitine l-tartrate may have helped increase oxygen delivery into the muscle cells themselves

The acyl carnitine is then converted to acyl CoA by the action of carnitine palmitoyltransferase II (CPT II), which leads to -oxidation

This means ALCAR HCl is only about 85% elemental acetyl L-carnitine
