Choline supplements are said to reduce cholesterol, control mood swings, and protect the liver from damage due to alcohol. They also may lower blood pressure, boost memory, and treat Alzheimer’s disease.

Choline may also enhance athletic performance.

Choline is a component of sphingomyelin and phosphatidylcholine, which are commonly used to build cell membranes. Choline is also a precursor for acetylcholine, a neurotransmitter that performs many functions relating to muscle control and memory.
