Why people double-check this for Histamine / MCAS

People searching for histamine intolerance answers are usually already in a decision moment. They do not need another generic ingredient page. They need to know whether this changes the answer for their body, their baby, or their symptoms.

What can still change the answer

Dose, product format, freshness, the rest of the label, and your own reaction pattern can all move an ingredient from fine to a problem or back again.

Why open Clarity
