Msm (Methylsulfonylmethane) for Allergy Relief

Research suggests that MSM may offer some benefit for allergy relief, particularly in the context of allergic rhinitis, though the evidence remains limited and preliminary. A 2020 systematic review analyzing data from dozens of randomized controlled trials and observational studies found promising but low-quality evidence for several supplements in managing allergic rhinitis, with MSM among the candidates identified in broader supplement literature as potentially relevant to immune and inflammatory responses. A 2017 narrative review of MSM research reported that the compound has demonstrated anti-inflammatory and antioxidant properties in both animal and human studies, and notes that it carries Generally Recognized As Safe status with a generally favorable tolerability profile. Studies indicate that while the existing findings point in a supportive direction, the overall body of evidence is small, methodologically varied, and not yet sufficient to draw firm conclusions, meaning individuals should weigh the available research carefully and consult a healthcare provider before using MSM for allergy-related purposes.
