Nährstoff | VitalCheck Basic: which supplements make sense?

The VitalCheck Basic from MyBody-X measures key nutrients like vitamin D, B12, folate, iron, magnesium, and zinc in blood. Supplementation makes sense only when a genuine deficiency is confirmed – not based on generic advice. A blood test can reveal deficits, but interpretation requires caution: acute infections, time of day, or recent meals can skew results. For confirmed deficiency (e.g., vitamin D < 30 nmol/l), supplementation is evidence-based (guidelines from DGE, Endocrine Society). For iron, B12, and magnesium, similar logic applies: only supplement when deficient or at increased need (pregnancy, vegan diet). Without deficiency, multivitamins show no proven benefit for healthy individuals – large trials (e.g., US Preventive Services Task Force) advise against routine use. The test is a useful screening tool, not a license for indiscriminate supplementation. Evidence grade: human-moderate (blood markers) to practice (clinical routine). Sources: no specific PMIDs in context; general nutrient guidelines apply.
