Wondering if your histamine intolerance or allergic reactions are actually an issue with mast cells? Histamine is secreted by mast cells into surrounding connective tissues when exposed to an allergen.

One relatively recent development in the treatment and management of MCAS involves considering drug and supplement excipients or inactive ingredients, rather than the actual drug itself.

Patients with MCAS typically have been struggling with inflammation-related symptoms over the years, which commonly include having allergies as a toddler, rashes, gut conditions, anxiety, headaches, and insomnia.

Antihistamines don’t actually reduce histamine release. They only block histamine receptors, preventing you from feeling the symptoms. Learn how to gain lasting relief from MCAS.
