CAM Type: biologically based

Common Names: Choline, Lecithin, Soy Lecithin

Introduction to Lecithin:

Lecithin, also called Choline, is a fatty substance typically derived from soy beans. Other sources include peanuts, eggs, and beef products.

Choline is considered part of the B-complex vitamins, and has been found to be a primary component of Lecithin. It is an integral part of cell membranes and can be totally metabolized, so it is virtually non-toxic to humans.

Common Uses:

Alertness, concentration, memory enhancement, other cognitive functions

Clinical research shows that supplementation with Choline may help support breathing, nervous system function, muscular movement, cognitive functions such as memory and attention, and the utilization of other fat soluble nutrients like Vitamin E and Vitamin K.

Preparation Methods:

Lecithin/Choline is found in many foods in a normal daily diet. Additional supplementation is available.

Pharmacology and Phytochemicals:

Researchers have determined that Lecithin consists of bio-active components Choline, Inositol, and Linoleic Acid, and other phytochemical constituents derived from Lecithin.

Mechanisms of Action:

Choline, Inositol, Linoleic Acid and the other phytochemical constituents which are derived from Lecithin are considered to be cofactors. Cofactors are the most important set of components required for fundamental processes throughout the body. Basic nervous system functions such as neurotransmitter synthesis and healthy communication between cells could not happen without the presence of necessary cofactors.


Daily usage of Lecithin in adults is normally around 100mg to 250mg, but can safely be taken at 1000mg to 1500mg per day.

Supplementing an already healthy diet with Lecithin/Choline may support physical performance and aid in concentration, alertness, memory and various other cognitive functions. Due to its nutritional value, Lecithin is formulated along with other vitamins, minerals and amino acids to help maintain physical/emotional wellness.

Safety, Side Effects and Warnings:

The FDA has recently required Choline to be included in all infant formulas. Current infant usages are 10mg to 50mg a day. Most children will receive sufficient Lecithin/Choline through a normal daily diet.

Though some side effects were reported in clinical trials, they occurred from highly elevated amounts of Choline supplementation in adults and included mild effects such as diarrhea and nausea.

Lecithin is well-tolerated and safe for use, but as with any supplement, it is important to seek the advice of a physician before taking any prescription medications with Lecithin supplementation.
