When the Immune System Becomes Overprotective
Mast cells are immune cells strategically located throughout the skin, lungs, digestive tract, connective tissue, and nervous system. Their normal role is to coordinate immune defense and tissue repair by releasing chemical messengers such as histamine, prostaglandins, cytokines, leukotrienes, and growth factors.1,2
In susceptible individuals, however, mast cells may become overly reactive, responding to foods, environmental triggers, stress, infections, temperature changes, hormones, or other stimuli with an exaggerated release of inflammatory mediators. This widespread activation may contribute to symptoms affecting multiple organ systems simultaneously.2,3
MCAS Support was developed to provide homeopathic support for the body's adaptive response to these complex immune signaling pathways by addressing many of the symptom patterns practitioners commonly observe in those experiencing mast cell activation and histamine dysregulation.*2,3

A Multi-System Approach to Mast Cell Support
Unlike products that focus only on histamine, MCAS Support was formulated to support multiple physiological systems commonly affected during mast cell activation.*

Histamine Regulation
Supports healthy histamine balance and appropriate immune signaling throughout the body.*2,6

Supports healthy inflammatory responses associated with flushing, redness, itching, hives, and swelling.*1,2

Gastrointestinal Function
Supports healthy digestion, intestinal comfort, and gastrointestinal immune balance.*7,8
Neuroimmune Communication
Supports healthy communication between the nervous system and immune system to promote cognitive comfort and resilience during periods of immune activation.*4,5

Liver & Histamine Metabolism
Supports the body's natural detoxification pathways involved in histamine metabolism and immune regulation.*6
Respiratory Comfort
Supports healthy respiratory function during seasonal and environmental immune challenges.*1,2
Who It's For
Practitioners may consider MCAS Support for those experiencing symptom patterns such as:
- Histamine sensitivity
- Flushing
- Hives

MCAS Support is not intended to replace any prescribed medications and should be used as part of a comprehensive approach under the guidance of a healthcare professional.
Experience These Results
Supports Immune Balance
Healthy mast cells are essential for appropriate immune communication. Supporting balanced mast cell activity helps with normal inflammatory signaling and tissue homeostasis.*1,2
Better Histamine Support
Histamine plays important roles far beyond allergic reactions, influencing digestion, circulation, neurological signaling, and immune communication. Healthy regulation supports appropriate physiological responses throughout the body.*6
Digestive Comfort
Nearly 70% of the body's immune system resides within the gastrointestinal tract. Mast cells located throughout the intestinal lining influence gut permeability, motility, digestive comfort, and immune tolerance. Supporting gastrointestinal immune balance may promote overall digestive wellness.*7,8
Nervous System Support
Mast cells communicate directly with nerve cells throughout the brain and peripheral nervous system. Healthy neuroimmune communication supports cognitive function, emotional resilience, sleep quality, and overall neurological comfort.*4,5
