Vitamin D Dosing Strategy
Vitamin D dosing strategy tailors intake to labs, sun, body size, and absorption—maintenance differs from supervised repletion when levels are low.
Vitamin D dosing strategy matches supplement amount to baseline 25-hydroxyvitamin D, sun exposure, body size, malabsorption, and obesity—fat tissue sequesters vitamin D, often requiring higher maintenance intakes. General adult maintenance often lands near 600–800 IU daily from food plus supplements, with repletion protocols higher under labs and medical oversight.
Take D3 with a meal containing fat for absorption.
Common questions
-
Should everyone take high-dose vitamin D?
No—test when indicated and dose to target. Blind megadoses risk toxicity and do not replace calcium, protein, and loading for bone health.
