29 Facts About Carnitine

What is Carnitine?

Carnitine is a nutrient that plays a crucial role in energy production. It helps transport fatty acids into the mitochondria, where they are burned for energy. Here are some fascinating facts about carnitine.

1. 01

   Carnitine is a naturally occurring compound found in nearly all cells of the body. It is derived from amino acids lysine and methionine.

2. 02

   The name "carnitine" comes from the Latin word "carnus," meaning flesh, because it was first isolated from meat.
