A targeted diamine oxidase (DAO) enzyme supplement delivering porcine-derived DAO2 in a capsule designed for release in the small intestine, where histamine from food is broken down — so you can eat with confidence rather than anxiety.
You have foods you love that your body has started to reject. Wine, aged cheese, fermented foods, cured meats, avocado, tomatoes, chocolate, citrus — the list grows quietly over months and years until eating out becomes a calculation and every meal carries a low-grade risk assessment. The symptoms are maddeningly inconsistent: sometimes you are fine, sometimes the same food triggers flushing, headaches, nasal congestion, bloating, stomach cramps, skin irritation, or a racing heart. Because the reactions are delayed and variable, you cannot pinpoint the cause with certainty. You eliminate foods one by one, shrinking your diet without ever solving the underlying problem, because the issue is not the food itself — it is your body's ability to process the histamine it contains.
Histamine is a naturally occurring compound found in varying concentrations across a wide range of foods, particularly those that are aged, fermented, cured, or left over. In a normally functioning digestive system, the enzyme diamine oxidase (DAO) breaks down ingested histamine in the small intestine before it enters the bloodstream. When DAO activity is insufficient — whether due to genetics, gut inflammation, medication interference, or age-related decline — histamine accumulates faster than it can be cleared. The threshold is breached, and symptoms appear. This is not a food allergy. It is not IBS. It is a functional enzyme insufficiency that conventional medicine frequently overlooks, leaving people cycling through elimination diets, antihistamines, and frustration without addressing the enzymatic root cause.
Seeking Health DAO Enzyme provides exogenous diamine oxidase sourced from porcine kidney protein — the same DAO enzyme your body produces naturally, delivered in supplemental form to support the breakdown of histamine at the point of ingestion. Each capsule is formulated for targeted release in the small intestine, where dietary histamine absorption occurs, ensuring the enzyme arrives where it is needed rather than being degraded by stomach acid. Take one capsule 15 to 20 minutes before a meal containing histamine-rich foods, and the supplemental DAO works alongside your body's own enzyme activity to clear histamine before it accumulates beyond your tolerance threshold. Suitable for adults and children over 4 years. Formulated by Dr Ben Lynch, a leading authority on nutrigenomics and methylation, and the author of Dirty Genes.
Seeking Health is a practitioner-founded brand built on the principle that genetic expression can be supported through targeted nutrition. Every product is designed around clinical research and formulated without unnecessary additives. 30 or 90 capsules per bottle.

People who have spent months or years eliminating foods without resolution understand that the problem may not be what they eat but how efficiently their body processes it. Choosing DAO supplementation reflects a shift from symptom avoidance to root-cause support — addressing the enzyme insufficiency rather than endlessly restricting the diet.
You gain mealtime confidence, which removes the anxiety and mental calculation that precedes every meal and enables you to eat a wider range of foods without dreading the aftermath.
You gain histamine clearance, which removes the accumulation that breaches your tolerance threshold and enables your body to process dietary histamine at the enzymatic level before symptoms appear.
You gain dietary freedom, which removes the progressive food restriction that shrinks your diet and social life and enables the reintroduction of foods you have been avoiding out of fear rather than confirmed allergy.
You gain symptom reduction, which removes the unpredictable flushing, headaches, bloating, and congestion triggered by histamine-rich meals and enables consistent, comfortable digestion regardless of menu.
You gain root-cause intervention, which removes the cycle of antihistamines and elimination diets that mask symptoms without solving them and enables targeted enzymatic support at the point where the problem actually occurs.
