Carnitine
TL;DR
L-Carnitine is a conditionally essential amino acid derivative synthesized from lysine and methionine. It is critical for transporting long-chain fatty acids into mitochondria for beta-oxidation (energy production).
Overview
L-Carnitine is a conditionally essential amino acid derivative synthesized from lysine and methionine. It is critical for transporting long-chain fatty acids into mitochondria for beta-oxidation (energy production). It also removes toxic acyl-CoA metabolites and has neuroprotective properties. ALCAR (acetyl-L-carnitine) crosses the blood-brain barrier.

Interactions
synergistic. ALCAR fuels mitochondrial fatty acid oxidation while ALA regenerates mitochondrial antioxidants; landmark studies show reversal of age-related mitochondrial decay in combination
synergistic. Carnitine shuttles fatty acids into mitochondria for beta-oxidation while CoQ10 optimizes the electron transport chain that generates ATP from those fatty acids
competes. L-carnitine may inhibit thyroid hormone entry into cell nuclei by blocking nuclear thyroid hormone receptors; has been used therapeutically to treat hyperthyroidism
enhances. L-carnitine (especially ALCAR) may potentiate warfarin anticoagulant effects by affecting vitamin K metabolism
