DAO plus - 50 capsules


DAO plus can be taken prior to a meal. The best way to take this is with water, however if you have difficulty swallowing, the contents of the capsule can be dissolved in a glass of water. DAO plus is suitable for children 4 years and older. After intake, the Diamine Oxidase enzyme is active for about 3-4 hours, because the capsule dissolves slowly in the intestines.

Take 1 capsule with some water just before a meal. Use a maximum of 3 capsules per day.

Frequently asked questions

about DAO plus – 50 capsules

DAO includes products containing the Diamine Oxidase enzyme. The DAO mini tablets contain only the Diamine Oxidase enzyme (DAO). The DAO Plus capsules contain Vitamin C and Quercetin in addition to the Diamine Oxidase enzyme.

The amount of the active Diamine Oxidase enzyme is the same in both products, 20,000 - 30,000 HDU per tablet/capsule. If you want to use only the Diamine Oxidase enzyme, you should choose the DAO mini tablets. These are easy to swallow (5mm diameter). If you also want the benefits of the additional active ingredients Vitamin C and Quercetin, choose the DAO plus. If would like to spread out the quantity of DAO enzyme during your day then it's possible to open up your recommended dose of 3 capsules and just take the small beige DAO tablets multiple times a day. That way you can still adhere to the maximum dose of 3 capsules a day but are able to take smaller dosages of the DAO enzyme.

Our DAO capsules and tablets are safe to use several times a day. We do recommend that you stick to the maximum set number of capsules/tablets per day. For DAO plus and DAO mini, this is a maximum of 1 capsule/tablet per meal for a maximum of 3 times per day.
