Vitamin D Repletion
Vitamin D repletion restores low vitamin D levels with sun, food, and guided supplementation over weeks. Lab testing should direct dose—not guesswork.
Vitamin D repletion is the process of restoring low blood vitamin D to adequate ranges through safe sun exposure, fortified foods, and supplementation guided by labs—not megadosing without testing. Deficiency links to bone health, immune function, and mood in some populations; repletion takes weeks to months depending on starting level and dose.
Pair with adequate calcium, magnesium, and resistance training for bone support.
Common questions
-
How long does vitamin D repletion take?
Many protocols show meaningful lab shifts over eight to twelve weeks, but dose and starting deficiency matter. Retest rather than staying on high doses indefinitely.
