Cashew Allergy
Cashew nut allergy is an abnormal immune response to cashews. When a person with this allergy eats cashews, their immune system reacts inappropriately and sends antibodies (usually immunoglobulin E IgE) to fight the cashew proteins, causing allergic symptoms, such as hives, swelling, trouble breathing, wheezing, and, in more serious cases, a life-threatening reaction known as anaphylaxis.

Antihistamine effects; may reduce allergic symptoms
How It Works
Cashew allergy is an IgE-mediated food allergy that can cause reactions ranging from mild (hives, itching, stomach upset) to severe anaphylaxis. Cashews are tree nuts, and people allergic to cashews are often also allergic to pistachios (they're closely related) and may cross-react with other tree nuts. Cashew allergy is one of the most common causes of fatal food anaphylaxis due to the severity of reactions it tends to cause.
CRITICAL: There is NO supplement that can treat, cure, or prevent anaphylaxis from cashew allergy. The only proven treatment for severe allergic reactions is epinephrine (EpiPen). If you have cashew allergy, you MUST carry epinephrine at all times and strictly avoid cashews and foods that may contain them. Cross-contamination is common in foods processed near tree nuts. Always read labels. Oral immunotherapy for cashew allergy is being developed but should only be done under medical supervision. These supplements may support general immune health but do NOT protect against allergic reactions.
* Vitamin D plays a role in immune regulation, and deficiency has been associated with increased risk and severity of allergic diseases. Maintaining adequate levels supports overall immune health.
* Probiotics may help modulate the immune system and reduce allergic inflammation through the gut-immune axis. They're being studied in the context of food allergy prevention and treatment, but are not a substitute for allergen avoidance.
* Omega-3 Fatty Acids have anti-inflammatory effects that may help reduce allergic inflammation.
* Quercetin is a natural mast cell stabilizer that may help reduce general allergic symptoms, but it will not prevent anaphylaxis.
* Vitamin C has mild antihistamine properties.
Expected timeline: These supplements support general immune health over time but will NOT prevent or treat allergic reactions to cashews. Never rely on supplements for allergy protection.
