Mechanism Of Action

It is the essential transport vehicle that carries fatty acids across the mitochondrial membrane. Without it, fat cannot enter the cellular engine to be oxidized and used as fuel.

Studied For

  • Fat oxidation / fatty acid transport
  • Energy metabolism
  • Exercise performance
  • Cognitive support / brain energy
  • Carnitine deficiency
  • Peripheral artery disease
  • Cardiovascular disease models
  • Male infertility / sperm motility
  • Insulin resistance models
  • Dialysis-related carnitine deficiency
  • Weight management adjunct
  • Muscle recovery
  • Fatigue reduction
  • Mitochondrial function support
  • Hepatic fat metabolism
  • Athletic endurance enhancement
  • Neuroprotection research
  • fat transport
  • fat burning
  • energy production
  • mitochondrial support
  • weight loss
  • athletic performance

Reported Research Findings

Levocarnitine is approved for carnitine deficiency. Supportive but mixed data exist for liver fat, cardiovascular endpoints, and (for the acetyl form) mood and neuropathy.

Safety And Handling Notes

At higher doses: nausea, cramps, diarrhea, and a fishy body odor. Use only the L (levo) form; D and DL forms are toxic.

An approved drug for deficiency; permitted in sport (only IV-infusion volume limits apply). Caution with seizure history and in kidney disease.

Regulatory Status

Levocarnitine FDA-approved Rx; also a supplement.

Approved DrugWeight Loss & Metabolism

Explain Like I'm 5

  • L-Carnitine acts like a tiny taxi cab for your fat. It picks up fat cells and drives them straight into your body's cellular furnaces so they can be burned for energy instead of being stored on your belly.

A fat-metabolism nutrient with an approved deficiency drug form.
