Karnitine Introduction

Karnitine (also called L-Carnitine) is an amino acid derivative that plays a key role in the body's energy production and metabolism. It is essential for the transport of fatty acids into the mitochondria, where they are broken down to produce energy. It also helps maintain healthy cholesterol and triglyceride levels. Karnitine is found in many foods, including red meat, fish, and dairy products, and is also available as a supplement.

Uses For Karnitine

Mechanism Of Action

Karnitine works by transporting long-chain fatty acids into mitochondria, the powerhouses of the cell. Once inside the mitochondria, the fatty acids are broken down to generate energy (ATP).
