DAO (Diamine Oxidase) Supplement｜ Food & Beverages

Feeling sluggish after histamine-rich meals? Many people experience bloating, skin flare-ups, or headaches after eating foods like cheese, wine, or fermented foods. This is often linked to histamine intolerance, which happens when your body doesn’t have enough of the key digestive enzyme, DAO (Diamine Oxidase).
Our DAO Capsules can support the natural breakdown of histamine in the body.

Diamine Oxidase is the primary enzyme that helps your body process histamine. If your DAO levels are low, histamine can build up and cause various issues after eating certain foods.
Naturecan’s DAO Supplement delivers a powerful 23,000 HDU (Histamine Degrading Units) per capsule. HDU is the measure of enzyme activity, the higher the number, the more effective it is at breaking down histamine.
With a high-strength, vegan-friendly formula, our DAO capsules can support your body every day. Backed by science, third-party tested, and made in Europe, they’re a trusted choice for anyone who wants more control over their digestion, and histamine metabolism.
Dosage Instructions
Take one capsule daily, ideally just before a meal ( even better if you know your meal might contain histamine). This way, DAO is right where you need it, when you need it.
Stick to the recommended dose and always check with your doctor if you are on medication or have any pre-existing health conditions and feel unsure.

What is Histamine Intolerance?
Histamine is a natural compound found in many foods and also produced by the body. It plays important roles in digestion, immune response, and the nervous system. Normally, enzymes like Diamine Oxidase (DAO) help break histamine down in the gut so it doesn’t accumulate.
Histamine intolerance happens when your body can’t process histamine effectively, usually because DAO levels are too low. This can lead to an excess build-up after eating histamine-rich foods such as aged cheese, red wine, fermented vegetables, or cured meats.
Common symptoms of histamine intolerance include:

Bloating, stomach cramps, or digestive discomfort

Flushing, itching, or skin irritation

Headaches or migraines after certain meals

Nasal congestion or allergy-like reactions

Unlike food allergies, histamine intolerance isn’t triggered by the immune system, it’s about your body’s reduced ability to clear histamine efficiently. That’s why some people may turn to DAO supplements for extra support in managing histamine levels and easing discomfort.
Who should consider taking a Diamine Oxidase supplement? 
DAO may be a great fit if you:

Often react badly to histamine-rich foods

Want to reduce bloating or digestive discomfort

Care about supporting longevity and overall wellness

People who are looking for an easy way to take back control of your diet

DAO is not suitable for children, or women who are pregnant or breastfeeding.
Ingredients Explained
What is DAO and How Does it Work? DAO is one of the body’s natural enzymes, working to keep histamine levels in check. Without enough of it, histamine builds up, which may lead to headaches, skin irritation, or digestive upset.
While some foods do contain DAO, it’s difficult to get a high enough concentration through diet alone. Supplementing with DAO gives you a reliable, concentrated amount every day that slots into your day-to-day routine with ease.
