What to watch with Fitness | LifestyleCheck and Haut?

When combining the Fitness, LifestyleCheck, and Skin (Haut) tests from MyBody-X, focus on overlapping biomarkers: vitamin D, omega-3 index, CRP (inflammation), and skin-relevant nutrients like zinc, selenium, and collagen precursors. The Fitness test may measure hormones such as testosterone and cortisol; LifestyleCheck provides a broad blood panel; the Skin test analyzes DNA variants for collagen quality, sun sensitivity, and antioxidant needs. Important: DNA effects are small and non-diagnostic; blood markers are more actionable but still not medical diagnoses. Use results to guide diet, supplementation, and training adjustments, not as a substitute for professional medical advice. Watch for interactions: high cortisol can worsen skin issues, low vitamin D impairs recovery. Evidence is mixed: blood tests have moderate evidence, DNA tests are mostly mechanistic or GWAS-based. None are clinically validated for medical decisions. For skin conditions like acne or eczema, consult a dermatologist.
