About Amanda

Amanda Callenberg is a Nutritional Therapist and founder of the Mind-Body-Biome™ Method, a framework that bridges nutrition, emotional health and microbiome science.

About the Mind-Body-Biome™ Method

The Mind-Body-Biome™ Method is an integrative approach to gut health that combines:
