The solution for DAO- Deficiency

DAO-Original supports your body’s natural DAO enzyme in cases of DAO deficiency and histamine intolerance. Our DAO supplement delivers the highest digestible amount of HDU in it’s purest form, naturally without additives.

Very good effect and tolerability
“Does what it says. I’ve been taking the capsules for about a week and had no more problems with histamine-containing food and wine. Now I don’t have to be so careful about what I eat anymore.”

Works better than tablets
“The effect of these capsules is better for me than with the tablets. Especially during the holidays, I won’t be able to avoid one or the other histamine-rich meal – then I’ll take a capsule beforehand and I’ll be able to tolerate it much better. I can only recommend it!”

Best product for my histamine intolerance
“I’ve been using the capsules for more than a year and nothing has worked as much as them so far. I can eat cheese, strawberries, tomatoes, etc. again without any problems, even red wine works again! It really did a lot for my quality of life!”

Why
choose
DAO Original?

Just the right amount

More is good but not always best. The human body can only digest up to 35.000 HDU (Histamine Degradation Units) efficiently. Anything more might sound nice but will essentially, well… discarded.
DAO Original provides the highest proven amount: 35.000 HDU

Only the best

DAO Original contains DAOgest® a clean, efficient and natural DAO extract.
No additives, dilutants or fancy extras.

Quality all the way

Using the highest quality ingredients is important, but the way the raw material is being produced matters just as much. That’s why we rely on GMP-controlled production in Catalunya, Spain.

The capsule

Yes, even the capsule matters. We use acid-resistant capsules to make sure the DAO reaches your intestines safely – without being broken down by stomach acid, unlike tablets that may dissolve too soon. Other advantages are reduced gastrointestinal discomfort, improved absorption and a better taste. So yes, it matters.

What is DAO Deficiency?

Diamine oxidase –DAO– is your body’s natural defense against too much histamine in food, the sneaky compound behind everything from headaches and hives to tummy troubles.

DAO works hard in your gut to break down histamine from the foods you eat, keeping things running smoothly.
But when DAO levels dip in your small intestine or the enzyme isn’t doing its job properly (hello, DAO deficiency), histamine can pile up and start causing all sorts of unwanted chaos. Think bloating, brain fog, skin flare-ups, and more.

Whether it’s due to genetics, gut health issues, or certain medications, low DAO activity can seriously throw you off balance. That’s where we come in—to help give your DAO a boost and bring your histamine back in check.

Soo.. what is DAO Original about?

What it is

A supplement that supplies natural, active diamine oxidase (DAO)—your body’s enzyme for breaking down histamine.

Why it matters

DAO helps regulate histamine levels in your gut, especially after eating histamine-rich foods.

When to take

If your DAO levels are low or blocked, histamine can build up and cause digestive or skin-related discomfort.

How it helps

DAO Original supports your body’s natural ability to manage histamine from food— keeping things calm and balanced.

More details

DAO Original is here to give your body a helping hand when histamine from food starts causing trouble.
Naturally, your body uses an enzyme called Diamine Oxidase (DAO) to break down histamine in the small intestine—specifically in the ileum and jejunum (fancy names, but think: your digestion’s frontline).
DAO also shows up in places like the kidneys and placenta, but its main job in the gut is keeping histamine from getting out of control.

When your DAO levels are low or the enzyme’s blocked, histamine can build up and trigger all sorts of uncomfortable reactions. That’s where DAO Original steps in—delivering active, natural DAO to support your system and help clear out that excess histamine before it causes chaos.

Think of it as your DAO gas station. Whenever you are running low on DAO, DAO Original fills up your tank.

How to use DAO Original

1 capsule, 15 minutes before

Before consuming any food or drink that might contain more histamine that your body can handle, take one capsule with enough water and dig in! We advise to take up to 3 capsules per day.

One last time, one capsule about 15 minutes before you consume your food or drink.
