  • Supplementation in the winter months
  • Support for bones, muscles, and resistance

Dosage & use

Often 10–25 mcg (400–1000 IU) per day; older adults and people with darker skin sometimes more. Follow the advice.

Cautions

Very high doses over a long period can be harmful. Consult in case of kidney or calcium metabolism problems.
