The global digestive diamine oxidase (DAO) enzyme supplement market is anticipated to experience substantial growth, expanding from USD 853.37 million in 2023 to USD 2,089.21 million by 2032, at a strong CAGR of 10.46% from 2024 to 2032. This growth is driven by rising consumer awareness of digestive health, increasing occurrences of food intolerances, and a shift toward preventive healthcare.
Diamine oxidase plays a vital role in the breakdown of histamine, a compound associated with allergic reactions and food intolerances. With health consciousness on the rise, consumers are seeking dietary supplements that can alleviate gastrointestinal discomfort and support digestive health. This heightened focus on digestive well-being is largely due to the growing prevalence of histamine intolerance, which has spurred interest in DAO supplements as a natural remedy.

North America currently holds the largest share of the market, supported by a well-informed consumer base and the presence of prominent market players. Additionally, robust R&D in dietary supplements further reinforces North America’s lead. In contrast, the Asia-Pacific region is projected to witness the fastest growth during the forecast period, propelled by rising health awareness and increasing popularity of dietary supplements in emerging markets.
