Diamine Oxidase (DAO) Enzyme Powder

Product Basics

Product Overview

Diamine oxidase (DAO) is a critical endogenous enzyme that drives histamine metabolism in the human body, primarily synthesized by the intestinal mucosal epithelium. Our DAO enzyme powder is extracted and purified from high-quality pea sprouts via advanced biological extraction and membrane purification processes, which maximally preserves enzyme bioactivity and ensures high purity and batch-to-batch consistency. This plant-sourced DAO is a premium functional raw material for formulations targeting histamine balance and digestive wellness.

Key Features & Benefits

Supports Healthy Histamine Metabolism As the core enzyme responsible for breaking down dietary histamine, DAO helps metabolize histamine from food into inactive byproducts, supporting comfortable digestion and maintaining normal histamine levels, especially for individuals with histamine sensitivity.

Promotes Intestinal Barrier Integrity DAO contributes to maintaining normal function and structural integrity of the intestinal mucosa. It supports a balanced gut microenvironment, which serves as the foundation for overall digestive and systemic wellness.

Supports Balanced Immune Response By regulating physiological histamine levels, DAO helps modulate normal immune function and supports a balanced inflammatory response, making it suitable for individuals with sensitive immune systems.

Application Fields

Dietary Supplements: Ideal for formulating capsules, tablets, and powder blends focused on histamine intolerance support, gut health maintenance, and immune balance.

Functional Food & Beverages: Suitable for incorporation into specialty nutritional formulas, sports nutrition products, and functional beverages to deliver targeted digestive health benefits.

Quality Assurance

We implement strict full-chain quality control from raw material sourcing to finished product release, ensuring every batch meets international quality standards.

Premium Raw Material Sourcing: We select non-GMO, contaminant-free pea sprouts as raw material, guaranteeing a natural, safe and fully traceable supply source.

Advanced Manufacturing Process: Industry-leading extraction, separation and purification technologies are applied to maximize enzyme activity retention and achieve high product purity, without unnecessary excipients.

Comprehensive Testing: Each batch undergoes full quality inspection covering appearance, enzyme activity, loss on drying, solvent residues, heavy metals (lead, arsenic, mercury, cadmium) and microbiological indicators (total plate count, yeast & mold, pathogenic bacteria). All tests follow USP standard methods including HPLC, ICP-MS and GC. Only batches that pass all specifications are released for sale.

Packaging & Storage

Packaging: Standard 25kg fiber drums lined with food-grade PE inner bags, ensuring product stability and safety during long-distance shipping and storage. Custom packaging specifications are available upon request.

Storage: Keep tightly sealed, protected from direct light, and stored in a cool, dry place. Under proper storage conditions, the product has a shelf life of 24 months.
