L-Carnitine Reference Guide

Compound Reference Overview

Field Value
Name L-Carnitine
Reference Code LCAR
Category Metabolic Compound
Example Strength 5000 mg multidose vial (varies by manufacturer)
Reference Range 500–2000 mg per injection, 2–3 times weekly
Frequency 2–3 times weekly
Key Safety Warning Injectable L-Carnitine bypasses gastrointestinal absorption limitations. Common adverse effect includes fishy body odor (trimethylamine production). Use caution in seizure disorders and thyroid dysfunction.

Mechanism of Action (Educational)

L-Carnitine is a naturally occurring amino acid derivative involved in the transport of long-chain fatty acids into the mitochondrial matrix for beta-oxidation.

It facilitates conversion of fatty acids into acetyl-CoA, supporting ATP production and cellular energy metabolism.

Deficiency states and impaired transport mechanisms have been studied in metabolic disorders and mitochondrial dysfunction.

Indications (Literature / Off-Label)

  • Fat metabolism support
  • Exercise performance research
  • Energy metabolism frameworks
  • Carnitine deficiency states

Administration (Clinical Use)

Parameter Details
Route IM injection or IV
Frequency 2–3 times weekly
Injection Sites IM: Deltoid or gluteal
Timing Morning or pre-workout preferred

Titration Schedule (Clinical Framework)

  • 1000–2000 mg, 2–3 times weekly from initiation

Lower initial dosing may reduce gastrointestinal or odor-related effects.

Pharmacokinetics (Literature)

  • Approximate half-life: ~17 hours
  • Energy effects often observed within days to weeks

Reconstitution & Concentration (Product Dependent)

Most injectable L-Carnitine is supplied as a liquid preparation.
Common concentration example:

Parameter Value
Formulation Pre-mixed liquid
Typical Concentration 500 mg/mL
Storage Room temperature or refrigerate (per manufacturer)

Conversion Reference (Example 500 mg/mL)

  • 1 mL = 500 mg
  • 2 mL = 1000 mg
  • 4 mL = 2000 mg
