MyBody-X angle on Vitamin D Senioren

Vitamin D in seniors is a relevant topic because endogenous synthesis declines with age, increasing fracture risk. MyBody-X typically offers blood tests for 25(OH)-vitamin D levels, not genetic risk assessment for deficiency. Evidence for routine supplementation in seniors is moderate: international guidelines recommend 800–1000 IU daily for fracture prevention, especially in frail or institutionalized individuals. However, routine screening of all seniors is not universally endorsed. Personalized genetics (e.g., VDR polymorphisms) currently lack sufficient clinical validity to guide dosing. Therefore, measuring blood levels is reasonable, but interpretation must consider diet, sun exposure, and medications. Caveat: high doses without medical supervision can be toxic. Evidence grade: mixed – practice recommendation for testing, but weak genetic component.
