What role does Vitamin D Test play in Wechseljahre?

The Vitamin D Test measures 25-hydroxyvitamin D (25(OH)D), the storage form. During menopause, declining estrogen increases osteoporosis risk, making adequate vitamin D status important for bone health. However, the test provides only a snapshot, heavily influenced by season, latitude, and supplementation. A single fingerstick result cannot diagnose deficiency or guide therapy alone – clinical follow-up with calcium, PTH, and possibly DXA scan is required. For other menopausal symptoms like mood changes or hot flashes, evidence for vitamin D is mixed; large trials show no consistent benefit. Self-supplementation with high doses (above 4000 IU/day) carries risks such as hypercalcemia. The test is useful as a screening tool but not as a standalone diagnostic or treatment decision.
