welche mineralien braucht der körper — can a microbiome test help?

The question of which minerals the body needs (e.g., calcium, magnesium, potassium, sodium, iron, zinc, iodine, selenium) is fundamental. A microbiome test can help indirectly: the gut microbiome influences mineral absorption and utilization. For instance, certain bacteria can enhance or impair the bioavailability of magnesium or iron. However, a microbiome test does not directly measure mineral levels in the body—blood or urine tests are required for that. The evidence for personalized recommendations from microbiome analysis is still limited (human-moderate). Many commercial tests overstate their utility. A microbiome test is most useful when dysbiosis or malabsorption is suspected, not as a routine mineral check. The DNA metabolism test (like the product mentioned) examines genes, not the microbiome. Both approaches can be complementary but do not replace clinical assessment.
