HistaMend DAO®: A Practical Guide to Histamine Support in the Digestive Tract
If you’ve ever noticed that certain foods or drinks don’t sit right—especially aged, fermented, or leftover foods—histamine may be part of the picture. HistaMend DAO® is formulated to support histamine metabolism in the digestive tract by providing diamine oxidase (DAO), the enzyme responsible for breaking down histamine in the gut.*
What I appreciate about this formula is that it doesn’t stop at DAO. It also includes supportive ingredients that support calm histamine activity and support the intestinal barrier.
What DAO is and why it matters
DAO (diamine oxidase) is the primary enzyme that helps metabolize histamine in the digestive tract.* When DAO activity is low—or when histamine intake is high—some people experience digestive discomfort after high-histamine meals.
This is why timing matters: the product information notes that taking HistaMend DAO® prior to consuming high-histamine foods and beverages helps defend against digestive histamine issues.*
What makes HistaMend DAO® different
Alongside DAO, this formula includes:
Maritime Pine Bark Extract (Pinus pinaster)
Pine bark is described as a potent free radical scavenger that may help inhibit the release of histamine from mast cells.* It’s also noted for supporting the up-regulation of mRNA expression of tight junction proteins, which ties into intestinal barrier support and overall gut health.*
Catalase
Catalase is included as an additional supportive enzyme. In formulas like this, it’s typically used to support digestive and oxidative balance.*
Vitamin C (as ascorbyl palmitate)
Vitamin C is included for added antioxidant support, which may help maintain overall immune and inflammatory balance.*
