Does vitamin D Help with histamine intolerance?

Individuals who have unusually low levels of the enzyme diamine oxidase may be more susceptible to histamine toxicity.

How do you stabilize mast cells naturally?

Is there a natural antihistamine?

Vitamin C

Vitamin C boosts the immune system. It also acts as a natural antihistamine.
