Does Phosphatidylcholine Improve Sleep?

Phosphatidylcholines are a sub-class of cholines, which are a major component of cellular membranes. This substance is sometimes referred to as PC and is an essential part of the nutrient lecithin. Occasionally, the terms lecithin and PC are used interchangeably. Phosphatidylcholine is heavily involved in the structure of membranes. It is most commonly found commercially in soy lecithin and is sold over-the-counter as a food supplement.

Features

According to a study published in the January 19, 2008 issue of the Journal of Lipid Research, phosphatidylcholine may be an essential nutrient for humans and other animals, but there is no indication that it improves sleep.

Function

PC has been used in several European and Asian countries for the treatment of Alzheimer's disease, stroke and traumatic coma.

Benefits

The phosphatidylcholine found in soy lecithin is taken by many consumers as a dietary supplement as a preventative for such ailments as high cholesterol, atherosclerosis, high blood pressure and liver problems.

Considerations

Because large amounts of phosphatidylcholine may increase symptoms of depression, it should only be taken by those being treated for depression while under a doctor's supervision.

Warning

Side effects of phosphatidylcholine may include problems breathing, chest pain and hives or other skin irritations. Should you experience any such side effects you should stop taking PC immediately and contact your doctor.
