Uses & Effectiveness
Possibly Ineffective for
- Gallbladder disease.
Likely InEffective for
- 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 for
- High cholesterol. Limited research shows that lecithin decreases cholesterol in healthy people and in people taking cholesterol-lowering therapy (statins). However, other evidence shows that lecithin has no effect on low-density lipoprotein (LDL) cholesterol or total cholesterol levels in people with high cholesterol.
- Manic-depressive disorder. Early research shows that taking lecithin improves symptoms of delusions, jumbled speech, and hallucinations in people with mania.
- Dry skin, dermatitis. Lecithin is often put in skin creams to help the skin retain moisture. People may tell you this works, but there is no reliable clinical research showing that lecithin is effective for this use.
- Athletic performance. Limited research shows that taking lecithin by mouth does not seem to improve athletic performance in trained athletes.
- Movement disorders (tardive dyskinesia). Early studies suggest 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.
- Parkinson’s disease. Early research shows that 32 grams lecithin daily does not improve clinical symptoms in people with Parkinson’s disease.
- Other conditions.
