What You'll Learn From Your Personalised Score

Digestive Patterns

Understand if bloating, irregular digestion, or gut discomfort could be linked to histamine sensitivity, not just random food reactions.

Skin and Sinus Reactivity

See if skin issues, rashes, congestion, or sinus pressure form a pattern that’s often overlooked in histamine intolerance.

Nervous System and Energy

Spot whether anxiety, fatigue, headaches, or brain fog are showing up as part of your histamine symptom picture.

Food Trigger Patterns

Reveal which foods or eating habits might be quietly triggering your symptoms, even if you once tolerated them.
