Choline: The B-Vitamin That Boosts Mitochondria & Fights Cancer
In this episode of her "Cancer and Biochemistry" series, Dr. Colleen Huber (NMD) explains the critical but underappreciated role of choline (a B-vitamin) in supporting mitochondrial function and defending against cancer. She details how choline supports the electron transport chain (especially Complex I), mitochondrial membrane integrity, ATP production, and healthy fat metabolism in the liver and brain—processes that help cells avoid the cancer metabolic pathway (Warburg effect).
Three Most Important Points:
Choline is essential for mitochondrial health: It maintains the integrity and function of the mitochondrial membrane and is required for proper Complex I activity in the electron transport chain.
Supports energy production and deters cancer metabolism: By enabling efficient ATP production via oxidative phosphorylation (rather than fermentation to lactate), choline helps steer cells away from the cancer pathway.
Dietary sources matter: Key sources include beef liver, eggs, and fish; deficiency impairs fat metabolism in liver and brain mitochondria.
