# L-Carnitine (Injectable)

*Also known as: Levocarnitine, Carnitine*

Amino-acid-derived compound involved in fatty-acid transport; injectable form used in "Lipo" mixes.

## Overview

L-carnitine is an amino-acid-derived compound that shuttles long-chain fatty acids into mitochondria for beta-oxidation, making it essential for fat metabolism and energy production. It is synthesized in the body from lysine and methionine and obtained from diet, especially meat. The injectable form appears in lipotropic mixes and recovery protocols, marketed for fat metabolism, energy, and athletic performance. Injectable L-carnitine has an estimated half-life of roughly 14 hours and about 70% bioavailability. L-carnitine is an approved medication (levocarnitine) for carnitine deficiency, so the safety and basic pharmacology are well characterized. The evidence for the supplemental and injectable uses that drive most interest (fat loss, performance) is weaker, with trials showing inconsistent results.
