We Asked a Doctor Who Actually Needs to Take a Vitamin D Supplement

  • A blood test determines vitamin D levels to decide if supplementation is needed.
  • Levels are measured in nmol/L, with specific ranges guiding deficiency and adequacy.
  • Seasonal sun exposure and geographic location affect vitamin D production.
  • Diet alone may not restore deficient levels; fortified foods can help but aren’t always sufficient.
  • High-dose vitamin D may be used initially, followed by re-testing to ensure proper dosing.
  • Aim for regular testing to maintain proper vitamin D status over time.
  • Supplement choice should consider brand reputation and accurate dosing.
  • Sun protection remains important to guard against skin aging and cancer.
  • Fatty fish and fortified foods are good vitamin D sources, but not always enough.
  • Deficiency symptoms may be subtle but impact energy and aging.
