Diamine Oxidase (DAO) Enzyme Powder
What role does diamine oxidase play in the field of nutrition?
1. Enteral nutrition support and intestinal barrier protection：
By supplementing plant-derived diamine oxidase, it can effectively enhance the function of the intestinal barrier and reduce gastrointestinal complications such as abdominal distension and diarrhea.
2. Dietary supplements for histamine intolerance
For patients with histamine intolerance (such as chronic urticaria, food allergy), oral DAO supplements can help break down histamine in food and relieve symptoms such as headache, rash, and digestive discomfort.

Conclusion: Above product meet standard
1. Histamine Degradation: Diamine oxidase effectively breaks down histamine in the body, thereby alleviating discomfort and allergic reactions caused by histamine accumulation.
2. Improving Food Intolerance: Enhancing diamine oxidase activity can relieve symptoms associated with food intolerance, such as abdominal pain and diarrhea.
3. Anti-inflammatory Effects: Diamine oxidase possesses anti-inflammatory properties, reducing inflammatory responses by regulating histamine levels.
4. Promoting Wound Healing: Research indicates diamine oxidase plays a crucial role in wound healing by regulating cell proliferation and migration.
Natural sources: No need to rely on animal extraction, vegetarian-friendly, suitable for vegan-eating people.
High stability: Plant-derived diamine oxidase remains active across a wide pH range, adapting to the complex environment of the gut.
Synergistic Nutrition: The vitamin C and zinc found in plants are co-factors of diamine oxidase, providing dual support for gut health.
Stable supply: Large-scale production, stable supply
