Evidence check: Vitamin D Test in the context of menopause

The question of vitamin D testing during menopause is relevant, but evidence for routine screening is mixed. Vitamin D is crucial for bone health, and menopause increases osteoporosis risk due to estrogen decline. A test can identify deficiency, which is common in older women. However, guidelines (e.g., USPSTF, DGE) do not recommend universal screening in asymptomatic individuals. Testing is reasonable in those with risk factors: dark skin, limited sun exposure, obesity, or malabsorption. Detecting deficiency (25(OH)D < 30 nmol/l) typically justifies supplementation, but the benefit of raising levels above 75 nmol/l is not clearly proven. Moreover, many commercial tests lack standardization, affecting comparability. Thus, a vitamin D test can be useful in a targeted clinical context but should not be viewed as a routine preventive measure. The evidence for the test itself (independent of supplementation) is weak. Recommendation: test only after medical evaluation, not as a standalone self-test without guidance.
