What is L-Carnitine

L-Carnitine is actually not a peptide, but a naturally occurring amino acid derivative. It plays a crucial role in energy production by transporting fatty acids into the mitochondria, where they’re burned for fuel. In other words, it helps convert fat into usable energy. While L-Carnitine is not a peptide, it is often used in supplement form—either orally or as an injection—for its potential to support fat metabolism, athletic performance, and recovery.

When used for fat metabolism, the idea is that L-Carnitine enhances the body’s ability to break down fat stores for energy, particularly during exercise. It may also aid in reducing muscle soreness and enhancing endurance. Additionally, some research suggests potential cognitive benefits, though more studies are needed.

As for dosing, oral supplementation typically ranges from 500 mg to 2,000 mg per day. When used as an injection (often called L-Carnitine L-Tartrate injections), doses might be around 500 to 1,000 mg a few times per week. Effects can vary, but noticeable improvements in energy or performance might be seen within a few weeks, especially when combined with regular exercise.
