Are you consuming an adequate amount of acetylcholine, or other phospholipids? The odds are that you are not.

The human body produces choline by methylation of phosphatidylethanolamine (from dietary sources such as lecithin and others) to form phosphatidylcholine in the liver by the PEMT enzyme. Phosphatidylcholine may also be consumed in the diet or by supplementation. Choline is oxidized to betaine which acts as an important methyl donor and osmolyte.
