Phosphatidylcholine is a chemical contained in eggs, soybeans, mustard, sunflower, and other foods.
The term "phosphatidylcholine" is sometimes used interchangeably with "lecithin," although the two are different. Choline is a component of phosphatidylcholine, which is a component of lecithin. Although closely related, these terms are not the same.
Because the body uses phosphatidylcholine to make a brain chemical called acetylcholine, there is some interest in using it for treating “brain-centered” conditions such as memory loss, Alzheimer's disease, anxiety, manic-depressive disorders, and a movement disorder called tardive dyskinesia.
Phosphatidylcholine is also used for treating hepatitis, eczema, gallbladder disease, circulation problems, high cholesterol, and premenstrual syndrome (PMS); for improving the effectiveness of kidney dialysis; for boosting the immune system; and for preventing aging.
Healthcare providers sometimes give phosphatidylcholine intravenously (by IV) for chest pain, fat globules in the blood (fat embolism), high cholesterol, liver disease, and fatty plaque deposits in arteries.
Phosphatidylcholine is injected under the skin (subcutaneously) for treating non-cancerous fatty tumors (lipomas), excess fat around the eyelids, and yellowish cholesterol deposits just under the surface of the skin (xanthelasmas).
Phosphatidylcholine is the primary active ingredient contained in cosmetic injection products used to "dissolve" fat. These products include Lipodissolve, Lipolight, Lipolyse, Lipotherapy, and others. Some cosmetic centers in several countries initially imported a prescription intravenous drug product from Germany known as Lipostabil. They used it subcutaneously for cosmetic purposes; however, the manufacturer of this product does not promote it for this use due to lack of reliable evidence. Some countries, such as Brazil, have banned importation of this product for cosmetic use. The U.S. Food and Drug Administration (FDA) has also issued a warning to sellers of Lipostabil for making false and misleading claims and because it is an unapproved drug in the U.S.
Phosphatidylcholine injections are now often compounded in pharmacies. However, in the U.S., phosphatidylcholine, when compounded and used as an injection, is considered an unapproved drug rather than a dietary supplement.
How does it work?
The body makes a brain chemical called acetylcholine from phosphatidylcholine. Acetylcholine is important for memory and other bodily functions. Since phosphatidylcholine might increase acetylcholine, there is interest in using it for improving memory and for conditions such as Alzheimer's disease.
Some researchers think phosphatidylcholine acts like a detergent and breaks down fat.
A certain form of phosphatidylcholine (polyunsaturated phosphatidylcholine) might provide protection against liver fibrosis and liver damage caused by drinking alcohol, although the exact mechanisms are not completely understood.
Possibly Effective for...
- Hepatitis C. Taking phosphatidylcholine by mouth, together with interferon, seems to improve liver function in people with hepatitis C.
- Inflammatory bowel disease (ulcerative colitis). Research suggests that taking a specific phosphatidylcholine product (Sterpur P-30 Granulat, Stern-Lecithin and Soja GmbH) daily for 3 months improves symptoms in people with ulcerative colitis.
Possibly Ineffective for...
- Hepatitis A. Taking phosphatidylcholine by mouth does not seem to improve liver function in people with hepatitis A.
- Improving a medical procedure called peritoneal dialysis. Taking phosphatidylcholine by mouth does not seem to improve a medical procedure called peritoneal dialysis.
- A movement disorder called tardive dyskinesia. Taking phosphatidylcholine by mouth does not seem to improve a movement disorder called tardive dyskinesia.
Insufficient Evidence to Rate Effectiveness for...
- Liver disease caused by alcohol. Early research suggests that taking phosphatidylcholine daily for 24 months does not increase survival in people with liver disease caused by drinking alcohol.
- Reducing fat deposits. Early research suggests that localized fatty deposits on the chin, thigh, hips, abdomen, back, neck, and elsewhere look smaller to study subjects after receiving injections of phosphatidylcholine under the skin. Improvements appear to last for 2-3 years or longer. In one study, 80% of patients reported improvements in facial fat deposits that lasted for up to 3 years. However, these results have been questioned because the studies were not well designed.
- Declining brain function caused by liver disease. Research suggests that taking phosphatidylcholine daily for 6-8 weeks does not improve declining brain function in people with liver disease or liver failure.
- Hepatitis B. Studies regarding hepatitis B show conflicting results. It is not clear if phosphatidylcholine is beneficial.
- Inability to break down cholesterol in the body. Research suggests that taking phosphatidylcholine does not reduce cholesterol levels in the body of people who are unable to break down cholesterol
- Treating non-cancerous fatty tumors (lipomas). There is one report that injecting a phosphatidylcholine solution directly into a lipoma can shrink the tumor by about 35%. However, this treatment might cause an unwanted reaction in the lipoma.
- Memory loss. There is early evidence that taking a single 25 mg dose of phosphatidylcholine (PC-55, TwinLab) can improve some measures of memory in healthy college students.
- Eyelid fat. There is some evidence that injecting a phosphatidylcholine solution reduces bulging lower eyelid fat pads in some people.
- Gallbladder disease.
- Manic-depressive illness.
- Circulation disorders of the arms and legs.
- Weight loss.
- Premenstrual syndrome (PMS).
- Alzheimer's disease.
- Depressed immunity.
- Preventing aging.
- Other conditions.
Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).
Phosphatidylcholine is POSSIBLY SAFE when taken by mouth or when injected just beneath the skin, short-term. The safety of long-term use is not known.
If phosphatidylcholine is injected directly into a fatty growth (lipoma), it might cause an inflammatory reaction that could make the tumor more fibrous. In one reported case, the patient who had this done had to have the lipoma removed by surgery.
Drying medications (Anticholinergic drugs)Interaction Rating: Moderate Be cautious with this combination.Talk with your health provider.
Some drying medications are called anticholinergic drugs. Phosphatidylcholine might increase chemicals that can decrease the effects of these drying medications.
Medications for Alzheimer's disease (Acetylcholinesterase (AChE) inhibitors)Interaction Rating: Moderate Be cautious with this combination.Talk with your health provider.
Phosphatidylcholine might increase a chemical in the body called acetylcholine. Medications for Alzheimer's called acetylcholinesterase inhibitors also increase the chemical acetylcholine. Taking phosphatidylcholine along with medications for Alzheimer's disease might increase effects and side effects of medications for Alzheimer's disease.
Various medications used for glaucoma, Alzheimer's disease, and other conditions (Cholinergic drugs)Interaction Rating: Moderate Be cautious with this combination.Talk with your health provider.
Phosphatidylcholine might increase a chemical in the body called acetylcholine. This chemical is similar to some medications used for glaucoma, Alzheimer's disease, and other conditions. Taking phosphatidylcholine with these medications might increase the chance of side effects.
Some of these medications used for glaucoma, Alzheimer's disease, and other conditions include pilocarpine (Pilocar and others), and others.
The following doses have been studied in scientific research:
- For hepatitis C: 1.8 grams of lecithin, which contains phosphatidylcholine, used daily with a medication called interferon.
