A mitochondrial approach to health, vitality, and longevity. Feed your cells' power plants and transform every system in your body.
BY GERALD J. SHAFFER · justgerald.com
Mitochondria are the ancient bacterial partners living inside nearly every cell of your body. They convert food into ATP — the energy currency that powers everything from your heartbeat to your thoughts. When they thrive, you thrive.

Your mitochondria produce over 40 kg of ATP daily — the molecule that powers every muscle contraction, thought, and heartbeat.
Mitochondria were once free-living bacteria that merged with our ancestors 2 billion years ago. They still carry their own DNA, separate from yours.
Mitochondrial dysfunction is implicated in Alzheimer's, Parkinson's, diabetes, heart disease, and accelerated aging. Fixing them fixes everything.
Specific nutrients — CoQ10, omega-3s, magnesium, B vitamins, polyphenols — directly fuel and protect mitochondrial function.
