welche nährstoffe fehlen bei haarausfall — can a DNA test help?

Hair loss can be linked to deficiencies in iron, zinc, biotin, vitamin D, selenium, and essential fatty acids. A DNA test cannot directly detect such deficiencies; it can only indicate genetic predispositions that might affect nutrient metabolism (e.g., variants in MTHFR, VDR, or FADS1). The evidence for these genetic links is weak to moderate, and clinical utility is limited. A blood test measuring actual nutrient levels is far more reliable. Moreover, hair loss is often driven by hormonal, inflammatory, or environmental factors that a DNA test cannot capture. Anyone experiencing persistent hair loss should consult a doctor before investing in genetic tests. MyBody-X tests provide hints, not diagnoses – nutrient deficiencies are best addressed through blood work and dietary adjustments.
