Each Person is Unique
Our three presentations are designed to best suit the needs of each individual. We offer two formats (tablets and capsules) and three different supplements.
Naturdao 3M Capsules are ideal for individuals who often experience slower digestion and prefer simple products without excipients, seeking original and natural solutions.

Naturdao 1M Tablets are our best-selling product due to their broad appeal, rapid availability in the digestive system, and high enzymatic activity.
Naturdao Plus Tablets are our newest addition to the DAO supplement range, formulated to support comprehensive management of DAO deficiency and related nutritional deficiencies.
As can be seen, our products have high enzymatic activity and behave differently within the body. We designed them this way because we know that each person is different, and therefore our best advice is to try each option in an alternating manner over a period of one to two weeks in a first phase to evaluate them personally.
Let’s now explore more details and their composition.
