Choline
Choline is a dietary component found in many protein and fat-containing foods. It is a cell-signaling molecule, acetylcholine precursor, and adds structural integrity to cell membranes.*
Choline, especially in lecithin form, is a basic dietary component found in the phospholipids of protein-containing foods such as eggs, meats, soybeans, or peanuts.
Like tyrosine, dietary choline is an effective neurotransmitter precursor - it has been suggested that choline is the precursor for the production of acetylcholine.* It is believed that acetylcholine is released in the brain and plays a part in many brain functions.*
