Hey, I'm Luanne

Luanne Hopkinson (GradDipHumNutr, BSc, ADipNutrMed) is a Histamine Intolerance and MCAS expert, clinical nutritionist, neuroplasticity coach, and founder of Happy Without Histamine.

After navigating her own MCAS and histamine intolerance journey, she now helps women with MCAS and histamine sensitivity stop chasing triggers and start creating real healing.

Through my 5R Histamine Modulation Protocol™, I combine gut microbiome repair with nervous system regulation to help the body feel safe again, so reactions settle, and life expands.

Because healing histamine intolerance isn’t about shrinking your world, it’s about getting back into it.
