For educational purposes only
This guide is educational information about allergy and immune health — it is not medical advice, diagnosis, or treatment, and it is not a substitute for care from a qualified doctor or allergist. It does not diagnose, treat, cure, or prevent any condition, and does not "boost" immunity beyond supporting normal healthy function. See a doctor or allergist for testing, diagnosis, and management, and do not start or stop any medication or supplement without medical advice. A severe allergic reaction (anaphylaxis) is a life-threatening emergency — signs include trouble breathing, swelling of the face, lips, or throat, widespread hives, or feeling faint. If you suspect anaphylaxis, use an epinephrine auto-injector if one is prescribed and call 911 immediately.
