The global shift toward preventive health and wellness has led to increased demand for supplements that offer targeted relief from food-related sensitivities. One supplement gaining traction is diamine oxidase (DAO), which supports the breakdown of histamine in the digestive tract.

A recent study on the Digestive Diamine Oxidase Enzyme Supplements Market reveals that the market is growing steadily, with projections showing a healthy CAGR of over 5.6% through 2032. This rise is largely attributed to growing awareness of histamine intolerance and the desire for natural enzyme solutions.

DAO enzyme supplements are especially popular among individuals sensitive to aged cheeses, wine, or fermented foods—items high in histamine. As demand for gut-friendly supplements increases, product innovation in capsule forms and improved bioavailability is helping manufacturers reach a wider customer base.

Geographically, North America leads the market, with Europe and Asia-Pacific following closely. As education around digestive enzymes and histamine metabolism continues to spread, DAO is expected to become a household name in the dietary supplement space.
