Xymogen’s HistDAO is designed to support the healthy degradation of food-derived histamine. It contains a patented enzyme formula that has been clinically tested and found to break down histamine in the digestive tract.

Here are some of the possible benefits of HistDAO:

• Supports healthy degradation of food-derived histamine: Histamine is a compound that is naturally produced by the body, but it can also be found in certain foods. When histamine levels are too high, it can cause symptoms such as hives, itching, and flushing. HistDAO helps to break down histamine in the digestive tract, which can help to reduce these symptoms.
• Enhances the presence of diamine oxidase in the digestive tract: Diamine oxidase (DAO) is an enzyme that helps to break down histamine. HistDAO contains a patented formula that has been shown to increase the presence of DAO in the digestive tract.
• Is not absorbed and does not have systemic activity: HistDAO is not absorbed into the bloodstream and does not have any systemic effects. This means that it is safe to take for people with histamine intolerance or allergies.
