What is it?When medical researchers use the term “lecithin,” they are referring to a
purified substance called phosphatidyl choline (PC) that belongs to a special category of
fat-soluble substances called phospholipids. Phospholipids are essential components of cell membranes. Supplements labelled as
“lecithin” usually contain 10–20% PC. Relatively pure PC supplements are
generally labelled as “phosphatidylcholine.” PC best duplicates supplements used
in medical research. Choline by itself (without the “phosphatidyl” group) is also available in foods
and supplements. In high amounts, however, pure choline can make people smell like fish, so
it’s rarely used, except in the small amounts found in multivitamin supplements. What does it do?PC acts as a supplier of choline, which is needed for cell membrane integrity and to
facilitate the movement of fats in and out of cells. It is also a component of the
neurotransmitter acetylcholine and is needed for normal brain functioning, particularly in
infants. Although the human body can synthesise choline, additional amounts from the diet are
considered essential under certain circumstances. For this reason, PC has been used in a
number of preliminary studies for a wide variety of neurological and psychiatric disorders,
though not every study suggests that supplemental choline is capable of reaching the
brain.1 Choline participates in many functions involving cellular components called
phospholipids. Where is it found?Choline, the major constituent of PC, is found in soybeans, liver,
oatmeal, cabbage, and cauliflower. Soybeans,
egg yolks, meat, and some vegetables contain PC. Lecithin (containing 10–20%
PC) is added to many processed foods in small amounts for the purpose of maintaining texture
consistency. Phosphatidyl choline has
been used in connection with the following conditions (refer to the
individual health concern for complete information):
Who is likely to be deficient?Although choline deficiencies have been artificially induced in people, little is known
about human deficiency in the real world. How much is usually taken?Small amounts of choline are present in many
B-complex and multivitamin supplements. Are there any side effects or interactions?With several grams of choline per day, some people will experience abdominal discomfort, diarrhoea, or nausea. Supplementing choline in large
amounts (over 1,000 mg per day) can lead to a fishy body odour. PC does not have this effect.
Depression has been reported as a side effect in
people taking large amounts of choline, such as 9 grams per day. The body uses both PC and pantothenic acid to form
acetylcholine. At the time of writing, there were no well-known drug interactions
with Lecithin/Phosphatidylcholine/Choline. References1. Dechent P, Pouwels PJW, Frahm J. Neither short-term nor long-term
