Choline

Choline is a molecule used as a building block to several other biochemicals in the human body. Although the body manufactures some choline, the majority of what is used needs to be consumed in food, such as eggs, meat, poultry, fish, cruciferous vegetables, peanuts, and dairy products.

A small study of CFS patients found increased choline in the basal ganglia. Another in the occipital cortex

Increased choline has been found in the certain brain structures of CFS patients, suggesting a possible increased oxidation of the cell membranes of neurons in these regions.
