Nährstoffcheck: what can you do yourself?

A nutrient check via home test can offer initial clues but does not replace medical diagnosis. What you can do yourself: 1) Eat a varied, whole-food diet rich in vegetables, fruits, whole grains, legumes, and nuts – this covers most micronutrients. 2) Vitamin D: If you have limited sun exposure (e.g., in winter), supplementation may be useful, but only after a blood test or medical advice. 3) Iron: Don't supplement blindly if you feel tired or pale; check ferritin levels first – especially if you carry HFE variants (like rs1800562) that increase risk of iron overload. 4) B vitamins: If you follow a vegan/vegetarian diet, pay attention to B12; consider a blood test or supplement. 5) Magnesium: For muscle cramps or stress, increase intake through food (nuts, seeds, leafy greens). 6) Microbiome: A stool test shows bacterial types but not disease – you can support diversity with fiber, fermented foods, and less sugar. Important: Day-to-day variation is normal; a single test does not reflect your true health. See a doctor for persistent symptoms.
