• Histamine tolerance support: Addressing headaches, flushing, digestive discomfort, or skin reactions after histamine-rich foods.
• Migraine management: Exploring histamine metabolism links to recurrent headaches.
• Skin sensitivity optimisation: Targeting unexplained itching, hives, or dermatitis.
• Food response refinement: Managing bloating, diarrhoea, congestion, or wheezing post-foods or alcohol.
• Drug tolerance evaluation: Assessing reactions to histamine-related medications.
• Mediator pattern insights: Clarifying allergic-like symptoms beyond IgE involvement.

DNA Histamine evaluates genetic variation in two key enzymes responsible for histamine breakdown: diamine oxidase (DAO), which primarily acts in the gut to metabolise dietary histamine, and histamine N-methyltransferase (HNMT), which helps regulate intracellular histamine levels in tissues such as the central nervous system. Histamine functions as an important signalling molecule across immune, neurological and gastrointestinal processes.

Differences in DAO and HNMT activity may influence how histamine accumulates or is cleared following food intake, environmental exposures or physiological stress. Altered histamine handling has been associated with symptom patterns including headaches, skin reactivity, digestive disturbances and selective medication intolerance amongst others.

Results are interpreted alongside dietary history, symptom patterns, medication use and other functional assessments. Reviewing genetic findings within this broader clinical context can support more personalised discussion around food strategies, environmental triggers and symptom management approaches.
