Overview
Prevention
Effective measures for the primary prevention of vitamin D deficiency include dietary intake and cutaneous synthesis. Cutaneous synthesis requires enough sun exposure and it depends on multiple factors including season, latitude, altitude, duration and skin pigmentation. However, there is a concern regarding sun exposure that increases skin cancer. So, it is not recommended to prevent vitamin D deficiency. [1]
- In 2011, the Institute of Medicine (IOM) recommended 600 IU/d of vitamin D for healthy persons over 1 year of age until 70. Recommended Dietary Allowance (RDA) of vitamin D for individuals over 70 years of age is 800 IU/d. RDA for pregnant and lactating women is the same as for nonpregnant adults. [2]
- The National Osteoporosis Foundation (NOF) recommends higer dose 800-1000 IU/d of vitamin D for adults age 50 and older.[3]
- In the UK, the Scientific Advisory Committee on Nutrition (SACN) recommends 400 IU/d of vitamin D (10 micrograms) for everyone above one year of age. Infants, from birth up to one year of age, as a precaution, should consume 340-400 IU/d of vitamin D (8.5-10 micrograms). [4]
- For the Europeans, the European Food Safety Authority (EFSA), published the recommendation as follows: [5]
- Infants aged 7-11 months: 10 µg/day
- for all other population groups aged one year and more (including pregnant/lactating women): 15 µg/day
