Although it has shown promise in some studies, more research is needed.
That means some supplement products may not contain what the label says.
These symptoms include:
The following highlights research conducted using lecithin for specific conditions.
Keep in mind that no supplement is intended to treat, cure, or prevent disease.
Don’t discontinue your prescription medication without first discussing with your healthcare provider how or when to use lecithin.
However, results for dementia treatment were unclear.
However, further research is warranted regarding lecithin’s specific effects.
High Cholesterol
Lecithin has been suggested to have anti-inflammatory andcardiovascular protective effects.
Mastitis
Mastitisis an inflammation of breast tissue.
It can occur in breastfeeding people.Clogged milk ductscan lead to mastitis.
Be sure to speak to a healthcare provider before using lecithin or other supplements during breastfeeding.
The group taking the higher dosage reportedly experienced the following:
More research is needed to confirm these results.
A number of older studies have examined the effects of lecithin on TD.
However, there isn’t enough evidence to warrant further study of lecithin’s effectiveness against TD.
Digestion
Lecithin may stimulate mucus production in the intestine.
This may aid digestion and help protect the lining of your gastrointestinal system.
Lecithin is sometimes suggested for people withirritable bowel syndrome (IBS).
However, some limited research suggests that soy lecithin may increase the abundance of undesirable gut bacteria.
Larger, more well-designed studies are needed before lecithin can be recommended for digestion and IBS.
Ulcerative Colitis
Some individuals withulcerative colitishave low levels ofphosphatidylcholine(also found in lecithin).
Ulcerative colitis is a punch in of inflammatory bowel disease (IBD) affecting the large intestine.
Gallbladder Disease
Lecithin supplements are sometimes used to prevent and limitgallstones.
However, the research supporting this use is limited.
More research must be done to understand if lecithin can help manage gallbladder disease.
In MASLD, fat builds up in the liver.
Over time, MASLD can lead to liver cirrhosis and liver failure.
Phosphatidylcholine is just one part of lecithin.
Wound Healing
Lecithin may help wounds heal faster.
One animal study found that soy and egg lecithin’sfree radicalscavenging activities could help speed wound healing.
However, that evidence is insufficient as effects in animal studies don’t necessarily translate into effects in humans.
Further research in humans is needed.
Nutrition
Lecithin is not a single substance.
It’s also used in CBD edibles, typically as soy lecithin.

Summary
Lecithin contains phospholipids.
It may be found in specific foods or taken as a supplement.
It is said to aid in the function of the brain, nerves, and other organs.
Lecithin has been studied for its use in preventing or treating various health conditions.
However, the evidence supporting its use for these conditions is weak; more studies are needed.
Lecithin is thought to be safe.
Still, check with your healthcare provider before taking any supplements.
You may need to avoid it if you have chronic kidney disease due to potential phosphorous content.
