Case Study

Case study: ZOE personalized nutrition platform

Overview:

ZOE is a personalized nutrition and digital health platform that leverages microbiome analysis, continuous glucose monitoring, blood fat testing, and artificial intelligence (AI) to provide individualized dietary recommendations. The company aims to improve metabolic health, support weight management, and prevent chronic disease through data-driven nutrition insights.
