Myths vs facts: Fitness Vitality DNA and gut health

Myths vs facts: Fitness Vitality DNA and gut health. Many direct-to-consumer tests claim that DNA analysis can provide precise recommendations for fitness and gut health. Fact: The evidence is limited. MyBody-X does not offer a gut microbiome test (stool analysis required). DNA variants like ADIPOQ or FUT2 have small effects on metabolism or microbiome – lifestyle and diet matter far more. The claim that a DNA test can predict the 'optimal' fitness or gut health strategy is overstated. Use such tests as curiosity, not prescription. Consult a doctor for real health concerns.
