Diamine Oxidase (DAO) Enzyme Supplements

Support healthy histamine levels and promote digestive comfort with our premium selection of Diamine Oxidase (DAO) enzyme supplements. DAO is the primary enzyme responsible for breaking down dietary histamine in the gut. When DAO levels are low—whether due to genetics, age, medications, or lifestyle factors—histamine can build up in the body, leading to symptoms such as headaches, bloating, flushing, nasal congestion, or skin discomfort.

DAO enzyme supplements are designed to replenish your body’s natural enzyme activity, helping restore balance and support overall wellness. By aiding histamine breakdown, DAO may help reduce common discomforts associated with histamine intolerance, while promoting digestive health, skin comfort, and healthy immune function.

At Vitamins Emporium, we carry trusted, high-quality DAO capsules and tablets made with clean ingredients, carefully formulated for effectiveness and purity. Many of our products are non-GMO, gluten-free, and manufactured under strict quality standards.
