What causes sudden release of histamine?

This causes an overgrowth of bacteria which converts histidine to high levels of histamine. Individuals who have unusually low levels of the enzyme diamine oxidase may be more susceptible to histamine toxicity.

What is the root cause of histamine intolerance?

Leaky Gut. In our practice, we often see histamine intolerance in conjunction with leaky gut. Since your intestines are where most of the DAO enzyme is produced, your body may produce less DAO when the gut is inflamed or damaged, thus leading to a build up of histamine.

What is the fastest way to reduce histamine?

Vitamins and minerals that may be good for people with histamine intolerance include:

  1. vitamin B-6, which helps DAO break down histamine.
  2. vitamin C to help lower histamine blood levels and help DAO break down histamine.
  3. copper, which helps raise DAO blood levels slightly and helps DAO break down histamine.
