SOLARAY DAO Enzyme 60000 HDU is an enteric-coated, plant-sourced supplement that supplies concentrated diamine oxidase to support dietary histamine breakdown.
If you want targeted assistance for processing histamine from food, SOLARAY’s DAO formula delivers 60,000 HDU (Histamine Degradation Units) in a vegan, pea-sprout-derived capsule designed to pass stomach acid and release in the small intestine. The product is made in a GMP-certified facility and bottled in post-consumer recycled resin as part of Solaray’s sustainability efforts.
DAO (diamine oxidase) is an enzyme naturally present in the digestive tract that helps neutralize histamine consumed in meals. SOLARAY provides a concentrated, plant-based DAO source intended to supply extra enzymatic capacity when dietary histamine load is high.
The enteric shield helps the capsule survive acidic stomach conditions and release its contents where DAO is most active—in the small intestine. That targeted release increases the likelihood that the enzyme reaches its site of action rather than being denatured in the stomach.
SOLARAY DAO is produced in a GMP-certified facility and tested in Solaray’s own laboratory in Utah. The capsule uses plant-based ingredients, and the bottles are made from post-consumer recycled resin as part of the brand’s waste-reduction steps.
Follow the label directions for serving size and timing; many users take DAO around mealtimes when consuming histamine-rich foods. Because this product contains a specialized enzyme, consistent usage near meals provides the most logical opportunity for it to act on dietary histamine.
Who is this for: SOLARAY DAO Enzyme 60000 HDU is aimed at adults seeking a vegan, plant-sourced enzymatic supplement to assist with the digestion of dietary histamine. It is suitable for those who prefer enteric-coated delivery, environmentally conscious packaging, and products manufactured in GMP-certified facilities. Not intended for children; consult a healthcare professional if you have health conditions, are pregnant, nursing or taking medications.
Diamine Oxidase (from Pea Sprouts) (Supplying 60,000 HDU); Other Ingredients: Cellulose, Vegetable Cellulose Capsule, Silica.
Q: Is SOLARAY DAO Enzyme vegan?
A: Yes. The DAO enzyme in this formula is plant-sourced from pea sprouts and the capsules are vegan.
Q: When should I take SOLARAY DAO Enzyme?
A: Take as directed near meals, especially when eating higher-histamine foods, for optimal opportunity to act in the small intestine.
