The body actually creates Acetylcholine out of Choline, an essential nutrient that also belongs to the B Vitamin family. While Choline is used to create Acetylcholine, it is also an essential part of lipids that make up cell membranes. Acetylcholine is found in the human nervous systems, as well as in the nervous systems of other mammals.

Acetylcholine was the very first neurotransmitter to be identified back in the early 1900s. It is made simply from choline and a two-carbon molecule called acetyl. Dietary choline and phosphatidylcholine (also known as lecithin) serve as the sources of free choline for acetylcholine synthesis. Acetylcholine is a neurotransmitter present in the brain and the peripheral nervous system, and acetylcholine receptors are found widely throughout the body and brain. Acetylcholine plays numerous roles. In the brain, acetylcholine is involved in learning and memory. Acetylcholine also stimulates muscle tissue. Acetylcholine is involved in Alzheimer’s disease.
How to Increase Acetylcholine levels Supplements such as choline and CDP-choline raise levels of acetylcholine.
