Nährstoffcheck: can a DNA test help?

A DNA test like MyBody-X can identify some genetic variants related to nutrient metabolism, such as in the SOD2 (rs4880), NRF2 (rs35652124), IL6 (rs1800795), or TNF (rs1800629) genes. However, effect sizes are generally very small, and the evidence is mostly based on mechanistic studies or GWAS – not on clinical intervention trials. This means the results can offer hints but not a reliable basis for personalized supplementation or diet. Lifestyle, diet, and overall health factors have a much larger impact. Marketing claims that suggest direct benefits for nutrient optimization should be viewed critically. A DNA test alone cannot replace medical advice or blood work. To truly improve your nutrient status, focus on proven strategies like a balanced diet, exercise, and medically supervised supplementation if needed. Genetics can serve as complementary information, but not as a standalone decision tool.
