Effects of dietary lecithin on hormonal and neurobehavioral profiles in normal subjects.
Four normal subjects received lecithin supplements sufficient to elevate serum choline levels 3-fold. Despite persistent hypercholinemia over 48 hours of close observation, no increase was observed in serum ACTH, cortisol, and insulin concentrations, or in free urinary catecholamine excretion. Screening of a large group of other pituitary and gonadal hormones also failed to reveal any influence of lecithin supplements. EEG patterns and results of psychometric tests were also unaltered.
