What it's actually good for

Recovery

Research Supported

Consistently shown to reduce markers of muscle damage and perceived soreness after exercise.

Muscle

Mixed Evidence

May increase androgen receptor density, potentially enhancing the response to resistance training.

How it works

Carnitine L-Tartrate is primarily used to enhance exercise recovery and increase androgen receptor density in muscle tissue. While commonly marketed for fat loss, human evidence for significant weight reduction is less robust than its recovery benefits.

It facilitates the transport of long-chain fatty acids into the mitochondria for energy production and reduces exercise-induced muscle damage by improving oxygenation.

Safety

Generally well-tolerated at doses up to 3g daily.
High doses may cause mild GI distress or a fishy body odor in some individuals.
May increase TMAO levels, though the clinical significance in humans is still being studied.
