Vegetable DAO Enzyme

We are proud to say that our Vegetable DAO is the PIONEER as such in the DAO deficit.

Role CAT-DAO-Histamine

Catalase enzyme (CAT) provides oxygen by favoring the balance for the decomposition of the DAO-Histamine reaction. Recent scientific studies made from human intestinal cells suggest that when histamine degrades by means of DAO , from this are released toxic compounds such as hydrogen peroxide, ammonia and imidazole acetaldehyde, however, with the presence of CAT this does not happen. See article.

HDU's vs Weight (mg)

Expressed with the English acronym HDU (Histamine Digesting Units). It is the correct way to quantify the activity and therefore the ability to degrade the DAO enzyme. It would be a mistake to express it in units of weight since it would not be giving any information of value to the consumer and there might be no activity because the enzyme is denatured.

Catalase enzyme (CAT)

Coming from the membranes of our legumes, it plays an important role. How to know if your product has Catalase enzyme.
