POSSIBLY INEFFECTIVE

• Athletic performance. Taking oral choline before exercise does not improve athletic performance. Details: Clinical research in trained athletes shows that taking oral choline 2.43 grams as a single dose does not delay fatigue during endurance sports when compared with placebo (5164). Other clinical research in untrained adults shows that taking oral choline 8.425 grams or 50 mg/kg once prior to participating in exhaustive, load-carrying exercise does not improve dexterity, upper or lower body strength, grip strength, or run time-to-exhaustion following exercise when compared with placebo (42229,42237).

INSUFFICIENT RELIABLE EVIDENCE to RATE

• Age-related cognitive decline. It is unclear if oral choline is beneficial in patients with age-related cognitive decline. Details: Small clinical studies in adults with memory loss shows that taking choline 2 grams four times daily orally for 21 days does not improve memory when compared with placebo (5170). Observational research in adults over 60 years of age has found that intake of choline 187-399.5 mg daily is associated with a 33% to 42% reduced odds of low cognitive function when compared with intake of less than 187 mg daily. Intake of more than 399.5 mg daily was not associated with low cognitive function when compared with less than 187 mg daily (109100).
• Allergic rhinitis (hay fever). It is unclear if oral choline is beneficial in patients with allergic rhinitis. Details: Preliminary clinical research shows that taking oral choline, as tricholine citrate, 500 mg three times daily for 8 weeks is less effective than intranasal budesonide 200 mcg twice daily for reducing symptoms of allergic rhinitis (42252).
• Alzheimer disease. Although there has been interest in using oral choline for Alzheimer disease, there is insufficient reliable information about the clinical effects of choline for this purpose.
• Asthma. Small clinical studies suggest that oral choline may modestly improve symptoms in patients with asthma. Details: Preliminary clinical research shows that taking choline 500-1000 mg orally three times daily for 3-4 months decreases the severity of symptoms, the number of symptomatic days, and the need to use bronchodilators in patients with asthma when compared with placebo (5165,5166). Preliminary data also shows that choline 3 grams daily might be more effective than 1.5 grams daily (5165).
• Autism spectrum disorder. Oral choline has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Clinical research shows that taking a combination of donepezil 2.5-5 mg daily and choline bitartrate 350 mg daily for 12 weeks improves receptive language skills, but no other outcomes, for up to 6 months after treatment when compared with placebo in children aged 5-10 years with autism spectrum disorder. Also, adolescents aged 11-16 years experienced no benefits, and some experienced an increase in behavioral symptoms, such as irritability (103571). It is unclear if this effect is due to choline, donepezil, or the combination.
• Breast Cancer. It is unclear if dietary intake of choline reduces the risk of breast cancer. Details: A meta-analysis of 6 low to moderate-quality observational studies suggests that neither high nor low dietary intake of choline is associated with breast cancer risk. This finding is largely influenced by inclusion of the European Prospective Investigation into Cancer and nutrition (EPIC) cohort study, which analyzed data from over 300,000 subjects. However, subanalysis of 3 case-control studies suggests that high dietary intake of choline may be associated with a decreased risk of breast cancer when compared with low choline intake (111416). The interpretation of these findings is limited by the heterogeneity of the included studies, self-reported data, and a small number of studies.
• Bronchitis. Although there has been interest in using oral and inhaled choline for bronchitis, there is insufficient reliable information about the clinical effects of choline for this purpose.
• Cancer. It is unclear if dietary choline intake reduces the risk for cancer. Details: A meta-analysis of 11 low-quality population studies has found that high dietary intake of choline is associated with an 18% lower risk of cancer when compared with low choline intake. High dietary intake of both choline and betaine was associated with a 40% lower risk of cancer (97390).
• Cardiovascular disease (CVD). It is unclear if dietary choline intake reduces the risk of CVD or improves outcomes in patients with CVD. Details: A meta-analysis of population research has found that high intake of dietary choline is not associated with a lower risk of coronary artery disease, stroke, or mortality when compared with a diet low in choline (97388). A more recent population study has found that energy-adjusted total choline intake is not associated with the incidence of CVD over ten years. However, the highest intake of free choline is associated with a 34% reduced risk of CVD when compared with the lowest intake (109104).
• Cerebellar ataxia. It is unclear if oral choline is beneficial in patients with cerebellar ataxia. Details: Despite some anecdotal reports suggesting that taking choline improves motor function, preliminary clinical research shows that taking choline 4-5 grams orally daily for 4 days to 6 weeks does not reduce cerebellar ataxia (5161,5173,23679).
• Cognitive function. It is unclear if oral choline is beneficial for improving cognitive function in healthy adults. Details: Preliminary clinical research shows that taking a single dose of choline 50 mg/kg orally prior to participating in an exhaustive, load-carrying task does not improve reaction time, reasoning, memory, or serial addition and subtraction ability following the task when compared with placebo (42237). Also, preliminary clinical research in patients requiring long-term total parenteral nutrition (TPN) shows that adding choline chloride 2 grams daily to TPN for 24 weeks might improve delayed visual memory, but does not improve other measures of cognitive performance, when compared with TPN alone (42232).
• Cirrhosis. Although there has been interest in using oral choline for cirrhosis, there is insufficient reliable information about the clinical effects of choline for this purpose.
• Complex partial seizures. Although there has been interest in using oral choline for complex partial seizures, there is insufficient reliable information about the clinical effects of choline for this purpose.
• Dementia. Although there has been interest in using oral choline for dementia, there is insufficient reliable information about the clinical effects of choline for this purpose.
• Depression. It is unclear if oral choline is beneficial for the treatment or prevention of depression. Details: Observational research has found that dietary choline intake of at least 198 mg daily is associated with a 32% to 43% decreased risk of depressive symptoms when compared with intakes of less than 198 mg daily (109106). It is unclear if choline supplementation is beneficial for depression.
• Diabetes. It is unclear if oral choline is beneficial for the treatment or prevention of type 2 diabetes; the available research is conflicting. Details: Preliminary clinical research shows that taking oral choline bitartrate 1000 mg daily for 2 months does not affect coagulation parameters or levels of triglycerides, low-density lipoprotein (LDL) cholesterol, or high-density lipoprotein (HDL) cholesterol in patients with type 2 diabetes (103569). Choline has also been evaluated for the prevention of type 2 diabetes. In Finnish males, observational research has found that dietary intake of total choline at levels of more than 482 mg daily, especially as phosphatidylcholine, is associated with a 25% lower risk of developing type 2 diabetes over the following 19.3 years when compared with intakes of less than 382 mg daily (103567). However, in males and females in the US, additional observational research has found no association between dietary choline and risk of type 2 diabetes over a mean of 9 years (103570). In addition, a sub-analysis found that the highest intakes of choline (a median of 487 mg daily) were associated with a 54% higher risk of type 2 diabetes among females, but not males, when compared with the lowest intakes (a median of 175 mg daily) (103570). Population research in patients with diabetes has found that an intake of dietary choline in amounts of at least 279 mg daily is associated with a 2.1-fold increased odds of diabetic retinopathy in females, but not males, when compared with an intake less than 206 mg daily (109102). It is unclear if choline itself is responsible for the increased odds of diabetic retinopathy in this population.
• Fetal alcohol spectrum disorders (FASD). It is unclear if oral choline improves cognition in children with fetal alcohol spectrum disorders (FASD). Details: Clinical research in children aged 2.5-5 years with FASD shows that taking oral choline bitartrate, providing choline 500 mg, daily for 9 months does not improve global cognitive development or hippocampal-dependent memory when compared with placebo. However, a subgroup analysis of only children aged 2.5-4 years suggests that choline may improve hippocampal-dependent memory (92112). Follow-up of this study at 7 years shows that choline improves motor speed and suggests a trend towards improved color naming, which are components of executive functioning testing, when compared with placebo (111745). The validity of these findings is limited by the high rate of patient discontinuation which limits statistical power. A small clinical trial in children 5-10 years old with FASD shows that taking oral glycerophosphocholine, providing choline 625 mg, daily for 6 weeks does not improve cognitive function, executive function, attention, or hyperactivity when compared with placebo (97389).
• Hepatitis. Although there has been interest in using oral choline for hepatitis, there is insufficient reliable information about the clinical effects of choline for this purpose.
• Huntington disease. Although there has been interest in using oral choline for Huntington disease, there is insufficient reliable information about the clinical effects of choline for this purpose.
• Hypertension. It is unclear if oral choline is beneficial for the prevention or treatment of hypertension. Details: Population research has found that every 100-mg increase in daily dietary choline intake is associated with a 15% decreased risk of developing hypertension over the next 4.6 to 9.1 years (109098). However, it is unclear if any benefits are specifically related to dietary choline or whether choline supplementation is beneficial.
• Infant development. It is unclear if oral choline intake during pregnancy is beneficial for infant development; the available research is conflicting. Details: Two observational studies have found that higher intake of choline during the second and third trimesters of pregnancy is associated with improvement in offspring cognitive development and visual memory at the age of 18 months and 7 years, respectively, when compared with lower choline intake (94654,94657). One of these studies found that each 1 mcmol/L increase in maternal blood levels of choline at 16 weeks' gestation was associated with a 2.23-point increase in cognitive skill score based on the Bayley Scales of Infant Development (BSID-III) at 18 months of age (94657). Also, some observational research has found that higher plasma levels of choline during pregnancy are associated with higher processing speed and decreased social withdrawal at 4 years of age in the offspring (109101). In contrast, 3 observational studies have found that higher intake of choline during pregnancy, as well as higher maternal and cord blood levels of choline, are not associated with improved offspring intelligence at 5 years of age or cognitive performance at 3 or 7 years of age (94654,94655,94656). However, many of these observational studies, including those with positive findings, included populations with a mean intake of choline that was below the recommended adequate intake of 450 mg daily (94654,94656). It's possible that higher intake of choline is needed to observe a benefit; however, research on the effects of choline supplementation is limited. One small clinical trial shows that taking choline 930 mg daily during the third trimester modestly improves sustained attention in the child at 7 years of age when compared with taking 480 mg daily (109105).
• Metabolic syndrome. It is unclear if oral choline is beneficial in patients with metabolic syndrome. Details: Preliminary clinical research in adults with metabolic syndrome shows that taking oral choline 400 mg daily for 4 weeks does not decrease body weight, blood pressure, plasma glucose levels, or low-density lipoprotein (LDL) cholesterol levels, or increase high-density lipoprotein (HDL) cholesterol levels, when compared with baseline (105731).
• Neural tube birth defects. It is unclear if oral choline intake is beneficial for preventing neural tube defects. Details: Population research has found that females who have a high dietary choline intake around the time of conception have a lower risk of having offspring with a neural tube defect when compared to those with lower intake (13134).
• Nonalcoholic fatty liver disease (NAFLD). It is unclear if oral choline is beneficial in patients with nonalcoholic fatty liver disease (NAFLD). Details: A cross-sectional analysis of results from observational and clinical research shows that low dietary intake of choline is associated with increased fibrosis in postmenopausal adults with NAFLD, but not in children, males, or premenopausal adults with NAFLD. Dietary choline intake was not associated with steatosis severity in any patient subgroup (92109).
• Schizophrenia. Although there has been interest in using oral choline for schizophrenia, there is insufficient reliable information about the clinical effects of choline for this purpose.
• Tourette syndrome. Although there has been interest in using oral choline for Tourette syndrome, there is insufficient reliable information about the clinical effects of choline for this purpose.
• TPN-associated hepatic steatosis. It is unclear if intravenous choline is beneficial in patients with TPN-associated hepatic steatosis. Details: In patients receiving long-term total parenteral nutrition (TPN), plasma levels of choline can decrease. Small, low-quality clinical studies show that administering intravenous choline 1-4 grams daily for 24 weeks improves some markers of TPN-associated hepatic steatosis when compared with baseline or placebo (5174,42235). More evidence is needed to rate choline for these uses.

LIKELY INEFFECTIVE

• Alzheimer disease. Lecithin does not improve daily functioning in patients with Alzheimer disease. Details: In patients with Alzheimer disease, taking various types of lecithin, 1.2-45 grams daily for up to 6 months, alone or in combination with various conventional medications, does not improve cognitive function or other measures of disease progression (5149,5151,5152,5156,14817,14823,14825,14837,14838).

INSUFFICIENT RELIABLE EVIDENCE to RATE

• Age-related cognitive decline. It is unclear if oral lecithin can slow age-related cognitive decline. Details: A small clinical crossover study in healthy adults aged 64 years and older shows that taking lecithin 26 grams orally daily, alone or in combination with physostigmine, for 5 weeks does not seem to improve memory when compared with placebo (19204).
• Anxiety. Although there is interest in using oral lecithin for anxiety, there is insufficient reliable information about the clinical effects of lecithin for this condition.
• Atopic dermatitis (eczema). Although there is interest in using oral lecithin for atopic dermatitis, there is insufficient reliable information about the clinical effects of lecithin for this condition.
• Bipolar disorder. It is unclear if oral lecithin is beneficial in patients with bipolar disorder. Details: A clinical study in six patients with mania shows that taking lecithin 10 mg three times daily improves symptoms of delusions, incoherent speech, and hallucinations when compared with placebo (14839).
• Dry skin. Although there is interest in using topical lecithin for dry skin, there is insufficient reliable information about the clinical effects of lecithin for this condition.
• Friedreich ataxia. Small clinical studies suggest that oral lecithin is not beneficial in people with Friedreich ataxia. Details: Preliminary clinical research shows that taking lecithin 25 grams orally daily for 1 month does not have any benefit in people with Friedreich ataxia (59298). Other preliminary clinical research shows that taking lecithin for a longer period of 6 months also does not improve performance (19211).
• Hyperlipidemia. Although lecithin may lower cholesterol in healthy people, it does not seem to improve cholesterol levels in people with hyperlipidemia. Details: Some clinical research shows that taking lecithin 20-30 grams daily for up to 11 months decreases cholesterol in healthy people (5147,14820). However, other clinical research shows that lecithin has no effect on low-density lipoprotein cholesterol or total cholesterol levels in people with hyperlipidemia (5148,14820).
• Parkinson disease. It is unclear if oral lecithin is beneficial in patients with Parkinson disease. Details: Preliminary clinical research in patients with Parkinson disease shows that taking lecithin 32 grams daily for 8 weeks does not improve symptoms when compared with placebo (19212).
• Postoperative pain. It is unclear if oral lecithin is beneficial for reducing postoperative pain. Details: Preliminary clinical research shows that taking lecithin 20 grams prior to surgery increases choline levels, but does not reduce postoperative pain after gynecological surgery, when compared with placebo (91231).
• Tardive dyskinesia. It is unclear if oral lecithin is beneficial in patients with tardive dyskinesia. Details: Two small clinical studies in patients with tardive dyskinesia shows that taking lecithin orally for 2 months, alone or in combination with lithium, does not improve symptoms when compared with placebo (14822,14824).
• TPN-associated hepatic steatosis. It is unclear if oral lecithin is beneficial in patients with hepatic steatosis associated with long-term total parenteral nutrition (TPN). Details: A small clinical study in patients on long-term TPN with low choline levels suggests that taking lecithin 20 grams orally twice daily for 6 weeks reduces the degree of hepatic steatosis, compared with no significant changes in those taking placebo (5140).
• Ulcerative colitis. Oral lecithin has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research shows that taking a disease-specific medical food (Profermin, Nordisk Rebalance) containing lecithin, fermented oats, barley malt, and lactobacillus plantarum, as 250 mL twice daily for 24 weeks, decreases disease activity by over 56% when compared with baseline and leads to remission in 46% of patients with mild-to-moderate ulcerative colitis (91228). Other preliminary clinical research in this population shows that taking Profermin 250 mL twice daily for 8 weeks improves disease activity and remission rate when compared with another medical food (Fresubin Original, Fresenius Kabi) (90271). The effects of lecithin alone are unclear. More evidence is needed to rate lecithin for these uses.

POSSIBLY EFFECTIVE

• Ulcerative colitis. Clinical research suggests that taking slow-release, phosphatidylcholine-rich phospholipids (Sterpur P-30 Granulat, Stern-Lecithin and Soja GmbH) improves symptoms and remission rate in patients with ulcerative colitis (68839,93389,93390,105728). A pooled analysis of 3 small randomized clinical trials in adults with chronic, active, ulcerative colitis at a single site shows that taking this specific form of phosphatidylcholine 1-4 grams daily for 3 months increases the odds of achieving clinical remission by 9.7 times when compared with placebo. Overall, 49% of the patients taking phosphatidylcholine achieved clinical remission. Taking phosphatidylcholine also improved quality of life and clinical improvement scores. In one study, this product also decreased the need for steroids, resulting in complete withdrawal of steroid therapy without exacerbation of disease in 80% of patients (93390). However, most patients in these studies were not treated with other standard therapies for ulcerative colitis, such as immunosuppressants and aminosalicylic acids. Subgroup analyses by dose suggest that the effective dose of this product is at least 1 gram daily; however, taking 3-4 grams daily may be more effective (93389,105728). In patients not responsive to mesalamine, some preliminary clinical research suggests taking LT-02 (Lipid Therapeutics GmbH), a modified-release formula of phosphatidylcholine, 3.2 grams daily for 12 weeks, improves symptoms of ulcerative colitis. Overall disease activity was improved by 52%, compared with 33% in those taking placebo. The effects on remission rate and mucosal healing were unclear; however, response rates were increased from 60% in the placebo group to 83% in the phosphatidylcholine group. In an 8-week follow-up, relapse was also less likely in patients treated with this product (93387).

POSSIBLY INEFFECTIVE

• Hepatitis A. Taking phosphatidylcholine orally does not seem to reduce serum bilirubin or liver enzyme levels in patients with hepatitis A (5225).
• Infant development. Clinical research suggests that taking phosphatidylcholine (PhosChol, Nutrasal) 5 grams daily, containing choline 750 mg daily, from 18 weeks' gestation to 90 days postpartum does not improve cognitive function in the infant at 10-12 months of age when compared with corn oil placebo (93386).
• Peritoneal dialysis. Taking phosphatidylcholine orally does not seem to improve ultrafiltration in peritoneal dialysis (5222).
• Tardive dyskinesia. Taking phosphatidylcholine orally does not seem to improve tardive dyskinesia (5223).

INSUFFICIENT RELIABLE EVIDENCE to RATE

• Acne. Preliminary clinical research suggests that topical application of a cream containing niacinamide and linoleic acid-rich phosphatidylcholine (4% niacinamide-phospholipidic; N-PHCL emulsion) once daily for 12 weeks appears to improve skin hydration and reduce acne lesions and inflammation when compared with a 1% clindamycin cream or a carrier-only cream in patients 15 years and older with moderate acne (93388).
• Alcohol-related liver disease. Preliminary clinical research suggests that taking polyunsaturated phosphatidylcholine 6 grams daily for 24 months does not increase survival compared to placebo in patients with acute alcoholic hepatitis (68843).
• Dementia. Population research in a sample of 1259 men in Finland found that those in the highest quartile of daily phosphatidylcholine intake have a 28% lower risk of being diagnosed with dementia than those in the lowest quartile, over a mean follow-up of about 22 years (103178).
• Fatty deposits. Preliminary clinical evidence suggests that subcutaneous injections of phosphatidylcholine can reduce localized fatty deposits on the chin, thigh, hips, abdomen, back, neck, and elsewhere, based on subjective visual assessments (15621,15625,15627). Improvements appear to last for 2-3 years or longer (15621,15627). In one study, phosphatidylcholine injections markedly or moderately reduce localized fatty deposits on the face in about 80% of patients for a period of up to 3 years based on subjective patient self-assessment (15621). The findings of these studies are severely limited by poor study quality.
• Hepatic encephalopathy. Clinical research suggests that taking polyunsaturated phosphatidylcholine 1050 mg daily for 6-8 weeks, either orally or through a nasogastric tube, does not improve recovery from encephalopathy compared with control in patients with acute or subacute liver failure. However, polyunsaturated phosphatidylcholine seems to reduce mortality compared to control in patients with subacute, but not acute, liver failure (68835).
• Hepatitis B. Clinical research using phosphatidylcholine for hepatitis B show conflicting results (5224,5226).
• Hepatitis C. Preliminary clinical research suggests that taking the polyunsaturated form of phosphatidylcholine orally, in combination with interferon, seems to help reduce liver enzymes in patients with chronic hepatitis C (5226).
• Hyperlipoproteinemia. Clinical research suggests that taking polyunsaturated phosphatidylcholine 1.8 grams daily for 28 days in combination with clofibrate does not significantly reduce total cholesterol, triglycerides, or phospholipids compared to clofibrate alone in patients with primary hyperlipoproteinemia of Fredrickson Types II or IV. However, taking the combination of polyunsaturated phosphatidylcholine plus clofibrate seems to significantly attenuate the relative increase in low-density lipoprotein (LDL) cholesterol compared to clofibrate alone (68840).
• Lipoma. An anecdotal report suggests that injecting a phosphatidylcholine solution directly into a lipoma can shrink the tumor by about 35%. However, in this report a major inflammatory reaction occurred, resulting in undesirable fibrotic changes to the tissue and eventual surgical excision of the lipoma (15622).
• Memory. Preliminary clinical evidence shows that taking a single dose of phosphatidylcholine 25 grams (PC-55, TwinLab) can improve some measures of memory in healthy college students (5228).
• Nonalcoholic fatty liver disease (NAFLD). Preliminary clinical research shows that taking phosphatidylcholine 600 mg orally three times daily for 24 weeks qualitatively improves liver echogenicity and structure on an ultrasound scan, suggesting a reduction in hepatic steatosis. There is also a small decrease in liver function test values, but with considerable variability both at baseline and at 24 weeks (103176,103177). Preliminary clinical evidence also suggests that taking a combination of the milk thistle constituent silybin, phosphatidylcholine, and vitamin E (Realsil, Instituto Biochimico Italiano) orally twice daily for 12 months improves liver function tests (LFTs) and liver histology in people with NAFLD (63244).
• Periorbital fat pad herniation. Preliminary clinical research suggests that injecting a phosphatidylcholine solution markedly reduces lower eyelid fat pads in people with bulging fat pads due to herniation. In some people, benefits appeared to last for a period of 9 months to 2 years or longer (15623,15628). More evidence is needed to rate phosphatidylcholine for these uses.

General ...Orally, choline is well tolerated when used appropriately. Adverse effects have been reported with doses exceeding the tolerable upper intake level (UL) of 3.5 grams daily.
Most Common Adverse Effects:
Orally: Fishy body odor. At high doses of at least 9 grams daily, choline has been reported to cause diarrhea, nausea, salivation, sweating, and vomiting.

Cardiovascular ...Orally, doses of choline greater than 7. 5 grams daily may cause low blood pressure (94648).

Gastrointestinal ...Orally, large doses of choline can cause nausea, vomiting, salivation, and anorexia (42275,91231). Gastrointestinal discomfort has reportedly occurred with doses of 9 grams daily, while gastroenteritis has reportedly occurred with doses of 32 grams daily (42291,42310). Doses of lecithin 100 grams standardized to 3.5% choline have reportedly caused diarrhea and fecal incontinence (42312).

Genitourinary ...Orally, large doses of choline greater than 9 grams daily have been reported to cause urinary incontinence (42291).

Neurologic/CNS ...Orally, high intake of choline may cause sweating due to peripheral cholinergic effects (42275).

General ...Phosphatidylcholine is generally well tolerated when used orally, subcutaneously, or topically. Orally, bloating, diarrhea, altered taste, nausea, vomiting, sweating, and itching have been reported with phosphatidylcholine (5229,63244,68843,93389,93390,105728). Ingesting large amounts of around 30 grams daily is associated with a higher incidence of gastrointestinal upset and diarrhea (5223). Subcutaneously, pain, burning, itching, tenderness to touch, bruising, edema, nodules, hematoma, and erythema at the injection site have been reported with phosphatidylcholine (1562,15623,15624,15625,15626,15627,15628). High subcutaneous doses exceeding 1.2 grams of phosphatidylcholine can cause nausea and abdominal pain in some people (15624). Injecting phosphatidylcholine directly into a lipoma can result in a significant inflammatory response and undesirable fibrotic tissues changes (15622).

Dermatologic ...When taken orally, phosphatidylcholine may increase sweating (5229) and itching (63244). When given subcutaneously, phosphatidylcholine can cause pain, burning, itching, tenderness to touch, bruising, edema, and erythema at the injection site. The pain, itching and erythema usually resolve within 2 days of treatment; however localized tenderness can last longer (15623,15624,15626,15627,15628). Edema and bruising usually resolve within 10 days of treatment (15621,15623,15625). Some people can also develop nodules or hematoma at the injection site. This usually resolves within 30 days (15627).

Gastrointestinal ...Ingesting large amounts of phosphatidylcholine (30 grams per day) can cause gastrointestinal upset and diarrhea (5223). However, bloating, diarrhea, altered taste, nausea, and vomiting have been reported with smaller doses (63244,68843,93389,93390,105728). Although moderate subcutaneous doses do not usually cause systemic side effects, high doses exceeding 1.2 grams of phosphatidylcholine can cause nausea and abdominal pain in some people (15624).

Musculoskeletal ...Injecting phosphatidylcholine directly into a lipoma can result in a significant inflammatory response and undesirable fibrotic tissue changes (15622).
