Vitamin C

Vitamin C, also known as ascorbic acid, is a water-soluble vitamin found particularly in citrus fruits and green vegetables.

Function
High levels of vitamin C are found in the pituitary, adrenal gland, pancreas, liver, spleen and brain.

Mast cell activation disorder
Numerous studies have found Vitamin C to be inversely correlated with histamine and that the administration of Vitamin C reduces blood histamine levels. It does this potentially through several mechanisms: by inhibiting mast cell production; by increasing diamine oxidase (an enzyme that breaks down histamine); by inhibiting mast cell degranulation (and the release of histamine in the first place), and by inhibiting histidine decarboxylase (the enzyme that forms histamine).
