It is also used in people receiving peritoneal dialysis. In combination with lithium, lecithin is used for a movement disorder called tardive dyskinesia.

Possibly Ineffective for...

Likely Ineffective for...

- Age-related memory impairment.
- Head injury.
- Dementia related to Alzheimer's disease or other causes. Taking lecithin alone or with tacrine or ergoloids does not seem to improve mental abilities in people with dementia. It also doesn't seem to slow the progression of Alzheimer's disease.
Insufficient Evidence to Rate Effectiveness for...
- Athletic performance. Early research shows that taking lecithin by mouth does not improve athletic performance in trained athletes.
- A nerve disease called Friedreich's ataxia. Early research shows that lecithin does not improve performance in people with Friedreich's ataxia.
- Fatty build-up in the liver. Early research shows that lecithin might reduce the accumulation of fat in the liver of people who are fed long-term through a needle in the vein (parenteral nutrition).
- High cholesterol. Early research shows that lecithin decreases cholesterol in healthy people. However, other research shows that lecithin does not lower cholesterol levels in people with high cholesterol.
- Mania. Early research shows that taking lecithin improves symptoms of delusions, jumbled speech, and hallucinations in people with mania.
- Parkinson's disease. Early research shows that taking lecithin by mouth does not improve symptoms in people with Parkinson's disease.
- Surgery. Early research shows that taking lecithin by mouth before surgery does not reduce pain after surgery.
- Movement disorders (tardive dyskinesia). Early research shows that taking lecithin by mouth, alone or in combination with lithium, does not appear to improve symptoms in people with tardive dyskinesia when used for 2 months.
- Inflammatory bowel disease (ulcerative colitis). Early research shows that taking a supplement called Profermin (Nordisk Rebalance, Denmark) 250 mL twice daily for 8-24 weeks improves symptoms in some people with ulcerative colitis.
