How are Pharmakogenetik Medicheck and Darmgesundheit related?

The Pharmakogenetik Medicheck and the Darmgesundheit (gut health) test from MyBody-X are two separate products analyzing different biological systems. The Medicheck examines genetic variants affecting drug metabolism (e.g., CYP450 enzymes), while the gut test assesses microbial composition. There is no established scientific link between them in the current evidence base. MyBody-X markets both as part of a holistic health check, but no published studies support the clinical utility of combining them. The evidence for both is rated as 'marketing' or 'unclear', as DTC tests often lack validation against clinical standards. A physician should be consulted before making therapeutic decisions.
