MSM offers allergy symptom relief
We aimed to understand how methylsulfonylmethane (MSM) impacts symptoms of allergic rhinitis through a well-structured randomized, double-blind study.

Participants, who were prone to allergic responses, were tested after taking varying doses of MSM following allergen exposure.

Interestingly, the results showed that MSM significantly eased nasal symptoms and improved airflow, making it a potential alternative to conventional allergy medications.

We’re excited by the findings, as MSM appeared effective without common side effects associated with typical treatments.

My son has suffered from rhinitis for years, often with a persistent runny nose. Despite numerous allergy medications proving ineffective, after giving him 1000mg of MSM twice daily for two weeks, I noticed significant improvement. Within days, his symptoms lessened, and he woke up less congested. I also started taking it and felt its effects as well.
