welche mikronährstoffe sollte man testen lassen — what can you do yourself?

Which micronutrients should you test? The answer depends on individual risk factors, symptoms, and diet. Broad panels testing dozens of vitamins and minerals are often unnecessary and costly. Targeted testing makes sense when a deficiency is suspected – for example, vitamin D with limited sun exposure, vitamin B12 on a vegan diet, or iron with fatigue or blood loss. Zinc, magnesium, and selenium are frequently marketed, but deficiency is rare without specific signs. Important: many home test kits lack standardization and clinical validity; a doctor-ordered blood test is more reliable. What you can do yourself: a balanced diet rich in vegetables, fruits, whole grains, legumes, and healthy fats covers most people's needs. Supplementing without a proven deficiency usually provides no benefit. The evidence for broad micronutrient screening is weak – it's more marketing than medicine. Caveat: if you have a chronic condition or take medications, consult a physician before testing.
