Health Notes

Lecithin/Phosphatidyl Choline

Lecithin/Phosphatidyl Choline
This nutrient has been used in connection with the following health goals
  • Reliable and relatively consistent scientific data showing a substantial health benefit.
  • Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
  • For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.

Our proprietary "Star-Rating" system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.

For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.

This supplement has been used in connection with the following health conditions:

High Homocysteine
Dose: 2 grams daily choline or 34 grams daily lecithin
Choline has been shown to lower homocysteine levels.(more)
High Cholesterol
Dose: Refer to label instructions
Taking lecithin supplements may be a useful way to lower cholesterol.(more)
Birth Defects
Dose: 500 mg choline per day
Choline appears to protect against neural tube defects when taken prior to and early in pregnancy, as it has similar biochemical effects as folic acid.(more)
Alzheimer's Disease
Dose: Refer to label instructions
Weak evidence suggests that moderate amounts of lecithin, a fat used by the body to build membranes that may be obtained through food sources, may slightly improve symptoms. (more)
Gallstones
Dose: Refer to label instructions
Phosphatidylcholine (PC)-a purified extract from lecithin-is a component of bile that helps protect against gallstones. Supplementing with it may help dissolve gallstones(more)
High Homocysteine
Dose: 2 grams daily choline or 34 grams daily lecithin

Betaine (trimethylglycine) (6 grams per day) and choline (2 grams per day) have each been shown to lower homocysteine levels.1, 2 Choline in the amount of 2.6 grams per day (provided as 34 grams per day of soy lecithin) has also been shown to lower homocysteine levels in a double-blind trial.3 More recently, 1.5 grams of betaine per day, an amount similar to that in a typical diet, also has been found to lower homocysteine levels.4 Doctors usually consider supplementation with these nutrients only when supplementation with folic acid, vitamin B6, and vitamin B12 do not reduce homocysteine levels sufficiently. The results of this study, however, point to the potential benefit of increasing one's intake of foods rich in betaine (such as whole wheat, spinach, beets, and other plant foods).

High Cholesterol
Dose: Refer to label instructionsAlthough lecithin has been reported to increase HDL cholesterol and lower LDL cholesterol,1 a review of the research found that the positive effect of lecithin was likely due to the polyunsaturated fat content of the lecithin.2 If this is so, it would make more sense to use inexpensive vegetable oil, rather than take lecithin supplements. However, an animal study found a cholesterol-lowering effect of lecithin independent of its polyunsaturate content.3 A double-blind trial found that 20 grams of soy lecithin per day for four weeks had no significant effect on total cholesterol, LDL cholesterol, HDL cholesterol, or triglycerides.4 Whether taking lecithin supplements is a useful way to lower cholesterol in people with elevated cholesterol levels remains unclear.

Birth Defects
Dose: 500 mg choline per dayIn a preliminary study of California mothers, those who had higher intakes of choline during the three months prior to conception were significantly less likely to give birth to a child with an NTD, compared with women with lower choline intakes.1 The possibility that choline may protect against NTDs is plausible, as choline has similar biochemical effects as folic acid, which is known to reduce NTD risk.

Alzheimer's Disease
Dose: Refer to label instructions

A double-blind trial of 20 to 25 grams per day of lecithin failed to produce improvements in mental function in people with Alzheimer's disease.1 However, there were improvements in a subgroup of people who did not fully comply with the program, suggesting that lower amounts of lecithin may possibly be helpful. Lecithin supplementation has also been studied in combination with a cholinesterase inhibitor drug called tacrine, with predominantly negative results.2, 3, 4, 5

Gallstones
Dose: Refer to label instructions

Phosphatidylcholine (PC)-a purified extract from lecithin-is one of the components of bile that helps protect against gallstone formation. Some preliminary studies suggest that 300-2,000 mg per day of PC may help dissolve gallstones.1, 2 Some doctors suggest PC supplements as part of gallstone treatment, though the supporting research is weak.3

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.
