Frequently Asked Questions

Why is the standard recommendation often too low?
US RDA = 600-800 IU. Set in 1990s based on bone health. Modern data (Holick 2011 et al.) suggests 2000-4000 IU/day for most adults. Especially: dark skin (5-10× more sun needed), high latitudes (winter UVB inadequate Oct-Apr above 35° lat), indoor lifestyles.
Should I test serum 25-OH-D?
Yes — single most useful biomarker. Target: 40-60 ng/mL (100-150 nmol/L). Kosten: $50-75 in US. Test 1-2× per year, especially end of winter (lowest) and end of summer (highest). Adjust dose based on level, not formula.
D3 vs D2?
D3 (cholecalciferol). Period. D2 (ergocalciferol) raises 25-OH-D less effectively, is less stable, and primarily exists for orthodox-religious / vegan reasons (D3 traditionally from lanolin, but vegan D3 exists from lichen).
