Soy Lecithin Allergy Symptoms

Soy lecithin allergens react by producing vast amounts of antibodies, known as immunoglobulin. Antibodies are mistakenly attacking healthy tissues of the body and causing the symptoms of allergic reactions. The most common symptoms include: coughing, sneezing, runny hose, hives, diarrhea, facial swelling, shortness of breath, a swollen tongue, difficulty swallowing, lowered blood pressure, excessive perspiration, fainting, anaphylactic shock, or even death.

These reactions are less dramatic and they are characterized by production of immunoglobulin A, G, or M, instead of the antibody immunoglobulin E. In these cases, reactions may occur anywhere from two hours to days after exposure to soy lecithin allergens.

It is estimated that about 90% of sufferers are able to tolerate doses up to 400 mg. Another option is to switch to a different type of lecithin supplement, for example, from egg yolks and sunflower.
