Phosphatidylcholine is a natural lipid component of lecithin known to
reduce cholesterol and maintain liver health. It protects against hyper-
lipoproteinemia, a condition marked by increased lipids in the blood, par-
ticularly the "bad" LDL cholesterol.
Because phosphatidylcholine is a precursor for the important memory-
boosting neurotransmitter acetylcholine, it also may improve cognitive
function. Studies have shown that Alzheimer's disease patients have
reduced levels of the enzyme responsible for converting choline into
acetylcholine within the brain. Phosphatidylcholine, by increasing acetyl-
choline levels, may lessen symptoms of Alzheimer's and other dementias.
