Viral Hepatitis and Lecithin

Lecithin contains a substance called phosphatidylcholine (PC). In Europe, phosphatidylcholine is also used to treat liver diseases, such as alcoholic fatty liver, alcoholic hepatitis, liver cirrhosis, and viral hepatitis.PC may enhance the effect of interferon treatment in people with chronic hepatitis C.

Lecithin contains a substance called phosphatidylcholine (PC) that is presumed to be responsible for its medicinal effects. Research has shown that PC enhanced the effect of interferon in people with chronic hepatitis C, but not in those with chronic hepatitis B.

Phosphatidylcholine is a major part of the membranes surrounding our cells. However, when you consume this substance it is broken down into the nutrient choline rather than being carried directly to cell membranes. Choline acts like folate, TMG (trimethylglycine), and SAMe (S-adenosylmethionine) to promote methylation.

In one double-blind study, it enhanced the effect of interferon in people with chronic hepatitis C, but not in those with chronic hepatitis B.⁵⁰ However, in an open study phosphatidylcholine failed to produce improvements in individuals with acute hepatitis.⁵¹

Ordinary lecithin contains about 10% to 20% phosphatidylcholine. However, European research has tended to use products concentrated to contain 90% phosphatidylcholine in lecithin, and the following dosages are based on that type of product. For liver disease, a typical dose is 350 to 500 mg taken three times daily.

• Integrative MD
• Nutritionist or dietitian

Safety Issues

Lecithin is believed to be generally safe. However, some people taking high dosages (several grams daily) experience minor but annoying side effects, such as abdominal discomfort, diarrhea, and nausea. Maximum safe dosages for young children, pregnant or nursing women, or those with severe liver or kidney disease have not been determined.

Also, because lecithin is typically derived from soy, people with soy allergies may want to avoid it.
