What is Histamine Intolerance?

Histamine intolerance isn't a true allergy, but a condition where your body has difficulty breaking down histamine from foods. This can happen if you have a deficiency or a lack of activity in the enzyme Diamine Oxidase (DAO).

What are the common symptoms of Histamine Intolerance?

Common symptoms can include digestive issues like bloating, abdominal discomfort, and diarrhea; skin reactions such as Urticaria or flushing; and other symptoms like head discomfort, a stuffy or runny nose.

Why might I need a DAO supplement?

Your body naturally produces the DAO enzyme, but various factors can lead to a deficiency or reduced activity. A DAO supplement can help by providing the essential enzyme needed to break down excess dietary histamine in your small intestine.

What is the difference between dietary histamine and environmental histamine?

Dietary histamine refers to the histamine compound naturally present in foods and beverages. Environmental histamine, on the other hand, is produced by the body's immune system in response to allergens and other triggers, such as pollen or dust.

Which foods are high in histamine?

Histamine is found in many common foods, particularly those that are fermented, cured, or aged. Common high-histamine foods include • Aged cheeses, sauerkraut, yogurt, kombucha, tomatoes, spinach, and avocados, cured meats, Alcoholic beverages
