ABP1 Assist (HISTA/GUT) contains diamine oxidase (DAO), an enzyme naturally found in the digestive tract that degrades histamine and other biogenic amines. This professional-grade supplement also supplies vitamin B6 (as pyridoxal-5′-phosphate) — a required cofactor for DAO function — along with apple polyphenols, rutin, and lyophilized thymus and kidney tissue to provide comprehensive support for histamine balance and immune modulation.
Two capsules provide sufficient DAO activity to degrade approximately 75,000 μM/hour of histidine (histamine precursor). DAO enzyme activity is sourced exclusively from New Zealand bovine kidney tissue, known for its purity and safety.
Key Mechanisms and Highlights
- DAO Enzyme: Facilitates histamine degradation and supports gut comfort.
- Vitamin B6 (P-5-P): Essential cofactor that enhances DAO enzyme activity.
- Apple Polyphenols & Rutin: Provide antioxidant and histamine-modulating support; may benefit those with sensitivities or seasonal discomforts.
- Thymus Glandular (Ovine): Source of endogenous DAO and immune-supportive cofactors.
This formulation pairs well with Histamine Scavenger and MC Balancer for layered histamine-scavenging support.
