Support for healthy histamine metabolism

HistDAO® is designed for individuals who struggle with histamine-related discomfort. This unique formula provides the natural enzyme diamine oxidase (DAO), which helps break down histamine in the digestive tract. By supporting your body’s ability to process histamine from foods, HistDAO® can help reduce symptoms like flushing, headaches, and digestive upset that often come from histamine-rich meals.

  • Simple, targeted formula with a single active ingredient—DAO.

Key Benefits

What’s Inside
