OmneDiem Histamine Complete is a targeted dietary supplement designed to support histamine balance from both food and internal sources. It combines the enzyme Diamine Oxidase (DAO) with select botanicals and cofactors to help your body naturally process excess histamine in the gastrointestinal tract and support seasonal / sinus comfort.

This formula is intended as a nutritional aid (not a treatment) and is optimized for those seeking supplemental support in managing histamine load from diet and mast cell release.

Key Ingredients & Their Role

• DAO (Diamine Oxidase) – 15,000 HDU (approx. 2.1 mg† porcine kidney extract): Supplies an enzyme that helps break down dietary histamine in the small intestine.

• Vitamin C (Ascorbic Acid) – 100 mg: Acts as an antioxidant cofactor and may support general histamine metabolism.

• Quercetin (from quercetin dihydrate) – 200 mg: A flavonoid often used for seasonal / mast cell support.

• Bromelain (2,400 GDU) – 75 mg: A proteolytic enzyme that can support absorption and modulate inflammatory processes.

• Stinging Nettle Root Extract (0.8%) – 75 mg: A botanical traditionally used to support sinus and respiratory comfort.

† “HDU” = histaminase units, a measure of DAO enzymatic activity.

Clinical / Research Highlights

• DAO supplementation is a known approach to support degradation of dietary histamine in the gut (i.e. non-systemic support).

• Quercetin has been studied in various contexts for mast cell modulation, histamine inhibition, and antioxidant support (e.g., in vitro and animal models).

• Bromelain and nettle have been used traditionally for respiratory and sinus health.

Directions for Use

Take one capsule about 15 minutes before meals when dietary histamine exposure is expected (i.e. with or just prior to a meal). Do not exceed the recommended dosage unless advised by a qualified practitioner.
