Fast-Acting Diamine Oxidase Enzyme - 120 Caps for Histamine Sensitivity Support

Powerful Histamine Support with Natural DAO Enzyme – Our premium formula provides a remarkable 30,000 HDU of Diamine Oxidase (DAO) per serving, an essential enzyme known for its ability to break down histamine in the gut. Designed specifically for those with histamine intolerance, this high-potency supplement allows you to enjoy a diverse range of foods without the discomfort of adverse reactions. By targeting histamine directly in the digestive tract, it alleviates troublesome symptoms such as flushing, bloating, nasal congestion, and headaches commonly associated with histamine-rich foods.

Combat Histamine Sensitivity & Enhance Digestion

  • Mitigates discomfort from histamine before it starts.
  • Degrades excess histamine from foods to prevent adverse reactions.
  • Essential support for sensitive individuals enjoying aged cheeses, fermented foods, red wine, and cured meats.
  • Reduces gastric distress, inflammation, and histamine-related symptoms.

Fast-Acting Formula for Immediate Relief

  • Begins to work within 20 minutes of ingestion.
  • Simply take before meals to prevent symptoms like stomach pain, itching, and dizziness.
  • Rapid-release vegetarian capsules ensure quick absorption.

Non-Systemic & Clinically Proven for Safety

Our product is formulated with clinically tested DAO, acting only in the digestive tract without affecting overall histamine levels in the body. Unlike traditional antihistamines that block receptors, our natural formula breaks down histamine without entering the bloodstream. This non-systemic approach offers a safe and reliable solution for daily histamine intolerance management, enhancing gut function and overall well-being.

Supports a Balanced Diet & Quality of Life

Histamine intolerance can often impose limitations on dietary choices and daily comfort, but our supplement empowers you with greater food freedom. By mitigating histamine overload, it alleviates flushing, nasal congestion, digestive disturbances, and skin reactions, allowing you to savor your meals without anxiety. Ideal for dining out or maintaining a histamine-restricted diet, this DAO supplement provides the essential digestive support for your optimal health and enhanced quality of life.
