Nährstoffcheck: what symptoms are typical?

A nutrient check (e.g., for vitamins, minerals, or trace elements) can indicate deficiencies or excesses. Typical symptoms are often non-specific and may have many causes. Common deficiency symptoms: fatigue, poor concentration, brittle nails, hair loss, muscle cramps, dry skin, frequent infections, or mood swings. Excess states (e.g., iron or vitamin A) can cause nausea, joint pain, or liver damage. Important: A nutrient check alone does not replace a medical diagnosis. Results should be discussed with a doctor, especially if you have existing conditions or take medications. The evidence for these symptoms is based on clinical practice and observational studies, not on randomized controlled trials. The reliability of home tests is limited; lab values can fluctuate daily. If results are abnormal, confirmatory tests and personalized advice are needed.
