Have you ever felt symptoms similar to an allergic reaction after eating certain foods? Do you often feel headaches, stomach problems and itching for no apparent reason? You may suffer from histamine intolerance. Histamine intolerance is a hypersensitivity to histamine, a natural substance in the body that helps the immune system fight pathogens and toxins. Symptoms of histamine intolerance can be similar to those of an allergic reaction and include headache, migraine, dizziness, itching, swelling, cramps, diarrhea, cough, asthma, runny nose and palpitations.

Our histamine intolerance test is a test that measures the level of the enzyme diamine oxidase (DAO) in the blood, which is necessary to break down histamine in food. By detecting your DAO level, we can determine whether you suffer from histamine intolerance or not.

The histamine intolerance test is particularly useful for people suffering from migraines, IBS, fibromyalgia and chronic fatigue, as these conditions are often associated with histamine intolerance. By finding out if you suffer from histamine intolerance, you can take the right steps to avoid foods rich in histamine and thereby reduce your symptoms.

If you suffer from histamine intolerance, it is important to avoid foods rich in histamine, such as red wine, tuna, sardines, cheeses, sausages and cold cuts, and certain fruits and vegetables. You can also take an enzyme containing diamine oxidase to break down histamine in food.

Let us help you find peace in your body again. Order your histamine intolerance test today and take the first step towards living a healthier and more comfortable life.
