Ixcela Internal Fitness™ Tracking

Built on Decades of Science

Science-Backed Recommendations

Ixcela’s science-based, actionable approach, decades of research in metabolomics, proteomics, and genomics, and proprietary technology makes Ixcela unique in the gut microbiome testing market. We don’t just provide you with data; we give you actionable results that help you make well-informed decisions regarding your health, wellness, and lifestyle. Traditional stool sample tests can be difficult to collect, and they only tell you what types of bacteria are in the gut.

Ixcela’s test tells you if your gut bacteria are producing the building blocks necessary to keep you healthy.
