What supplements have been studied for allergic rhinitis?

Quercetin, spirulina, butterbur, and probiotics (particularly L. rhamnosus GG) have clinical evidence for allergic rhinitis. Quercetin acts as a natural mast cell stabilizer, while spirulina may help modulate the Th1/Th2 immune balance involved in allergic responses.

Can supplements replace antihistamines for allergies?

Supplements should not replace proven allergy medications without consulting a healthcare provider. While quercetin and spirulina show promising results, their effects are generally milder than prescription antihistamines. They may be considered as complementary approaches.

When should I see a doctor for allergic rhinitis?

Consult a doctor if over-the-counter remedies are ineffective, if allergies significantly impair sleep or daily activities, if you develop sinus infections or ear problems, or if you experience asthma-like symptoms such as wheezing and chest tightness alongside nasal symptoms.
