Lecithin consumption raises serum-free-choline levels.
Wurtman RJ, Hirsch MJ,
Growdon JH.
Consumption of choline by rats sequentially increases serum-choline,
brain-choline, and brain-acetylcholine concentrations. In man
consumption of choline increases in levels in the serum and
cerebrospinal fluid; its administration is an effective way of
treating tardive dyskinesia. We found that oral lecithin is
considerably more effective in raising human serum-choline levels
than an equivalent quantity of choline chloride. 30 minutes after
ingestion of choline chloride (2-3 g free base), serum-choline
levels rose by 86% and returned to normal values within 4 hours; 1
hour after lecithin ingestion, these levels rose by 265% and
remained significantly raised for 12 hours. Lecithin may therefore
be the method of choice for accelerating acetylcholine synthesis by
increasing the availability of choline, its precursor in the blood.
