'Mitochondria are tiny organelles, originally thought to be derived from bacteria. Red blood cells and skin cells have very little to none, while germ cells have 100,000, but most cells have one to 2,000 of them. They're the primary source of energy for your body.
In order for your organs to function properly, they require energy, and that energy is produced by the mitochondria.
Since mitochondrial function is at the very heart of everything that occurs in your body, optimizing mitochondrial function - and preventing mitochondrial dysfunction by making sure you get all the right nutrients and precursors your mitochondria need - is extremely important for health and disease prevention.'
