Additions: Vitamin D3 supplements are available in the form of pills, capsules or drops. It is important to choose a dietary supplement that contains vitamin D3 (cholecalciferol) instead of vitamin D2 (ergocalciferol), since vitamin D3 increases the vitamin D level in the blood more effectively.

Infants 0-12 months: 400-1000 IE/day
Children 1-18 years: 600-1000 IE/day
Adults 19-70 years: 600-800 IE/day
Adults over 70 years: 800-1000 IE/day
