Diamin oxidase (DAO)

Testing DAO levels is beneficial for individuals experiencing symptoms of histamine intolerance, such as headaches, skin irritation, or digestive issues. It’s also useful for those with allergies, gastrointestinal disorders, or those seeking to understand unexplained symptoms related to histamine activity.

• Headaches or migraines
• Digestive disturbances
• Skin rashes or hives
• Nasal congestion or sneezing
• Fatigue
• Irregular menstrual cycle
• Nausea or vomiting

Histamine intolerance arises from the body’s inability to break down histamine efficiently, leading to an accumulation of histamine. Allergy is an immune response to a foreign substance. Both can share similar symptoms like hives, sneezing, or itching, but the underlying causes differ.

To improve histamine intolerance:

• Consider supplements like quercetin and DAO enzyme, which help reduce histamine levels.
• Adopt a low-histamine diet by avoiding foods high in histamine.
• Ensure gut health to improve DAO production.
• Manage stress, as it can exacerbate histamine release.
