welche mineralien braucht der körper — what can you do yourself?

The question about essential minerals is valid, but the provided contexts contain no specific information on minerals. They exclusively cover genetic variants (e.g., rs9923231 in VKORC1, rs6721961, FADS1, MTHFR) related to pharmacogenetics, fatty acid metabolism, and folate. For an evidence-based answer on minerals, we must rely on general physiological knowledge: the body requires macrominerals such as calcium, magnesium, potassium, sodium, phosphorus, and chloride, as well as trace minerals like iron, zinc, copper, selenium, iodine, manganese, molybdenum, and chromium. What you can do yourself: maintain a varied, whole-food diet rich in vegetables, legumes, nuts, whole grains, and optionally fortified foods. If a deficiency is medically confirmed, targeted supplementation may be beneficial. Indiscriminate use of mineral supplements without a proven deficit is not recommended and can be harmful (e.g., calcium overdose, iron overload). The genetic tests in the context have no direct relevance to mineral requirements or supplementation. Evidence: general physiological knowledge, not derived from the given sources.
