What role does Nährstoffcheck play in Wechseljahre?

The role of the Nährstoffcheck (nutrient check) in menopause is not directly addressed in the provided context. In general, nutrient testing (e.g., for vitamin D, calcium, B12, iron) may help identify deficiencies common during menopause due to hormonal changes and aging. However, the evidence for clinical utility of such consumer tests is weak: most markers have small effect sizes, and results are highly dependent on diet, lifestyle, and individual physiology. Moreover, the given sources lack specific studies or guidelines validating the Nährstoffcheck for menopause. Therefore, medical evaluation (e.g., blood work, hormone panel) is preferable. The nutrient check may offer rough guidance but does not replace professional diagnosis. Evidence grade: marketing/unclear.
