Lecithin Side Effects

In clinical studies on lecithin, side effects that were reported include abdominal pain or fullness, nausea, and diarrhea. Since the product is derived from either egg or soy, people with egg or soy allergies may also develop allergic reactions with the supplements. In general, side effects of lecithin are usually associated with problems in the digestive system.

Does Lecithin Cause Side Effects?

Lecithin is a dietary supplement. People often assume that dietary supplements are always free of side effects, but this is simply not the case. It is reasonable to assume that any supplement potent enough to have medicinal properties may also have side effects. Most of the reported lecithin side effects are problems with the digestive system.
 

Reported Side Effects of Lecithin

In studies, reported side effects of lecithin included:
 
  • Nausea
  • Diarrhea
  • Abdominal pain or fullness.
     
Lecithin is derived from either egg or soy. Therefore, people with egg or soy allergies may develop allergic reactions to lecithin. Seek immediate medication attention if you develop signs of an allergic reaction, such as:
 
  • A rash or hives
  • Itching
  • Swelling of the lips, mouth, or throat
  • Wheezing or difficulty breathing.
     

Final Thoughts on Lecithin Side Effects

It is possible that you may experience some or none of the lecithin side effects explained above. Unfortunately, there is no way for you to know beforehand if you will have side effects from a medicine or supplement that you have never tried. Make sure to let your healthcare provider know if you develop any side effects while taking lecithin or if something "just does not seem right" during treatment. While it may not be a side effect, your healthcare provider will be able to diagnose and treat the problem.
