Cholesterol Home > Soy Lecithin Side Effects

Although problems are unlikely to occur with soy lecithin, side effects may occur with the supplementation form, as there are higher amounts of soy lecithin in these supplements. Some of the reported side effects of these supplements include stomach pain, diarrhea, and nausea. Since soy lecithin is derived from soy, people with soy allergies may develop allergic reactions to this product.

Does Soy Lecithin Cause Side Effects?

Soy lecithin, when used as a food additive (usually in tiny amounts), is unlikely to cause side effects. However, the use of soy lecithin as a dietary supplement (usually in higher amounts) may cause side effects. People often assume that dietary supplements are always free of side effects. However, 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 soy lecithin side effects are problems with the digestive system.

Reported Side Effects of Soy Lecithin

In clinical studies, reported soy lecithin side effects included:
  • Diarrhea
  • Nausea
  • Abdominal (stomach) pain or fullness.
Soy lecithin is derived from soy. Therefore, people with soy allergies may develop allergic reactions to soy lecithin, although this is not always the case, depending on the exact type of soy allergy. Seek immediate medical attention if you develop signs of an allergic reaction, such as:
  • Swelling of the lips, mouth, or throat
  • A rash or hives
  • Itching
  • Wheezing or difficulty breathing.

Final Thoughts on Soy Lecithin Side Effects

While it may not be a side effect, your healthcare provider will be able to diagnose and treat the problem.
