Babies: 400 IU per day, with more (800 – 1200 IU per day) in winter months, and after 1 year (as weight increases, so does necessary dose).

Adults, non-pregnant: Recommendations range, as do individual needs. *Get your blood levels checked first. Common supplemental doses range from 2000- 5000 IU per day, although some people do not require supplementation.
