Vitamin D supplementation of 10 micrograms (400IU) per day recommended for all age groups during the winter months

9th December 2020

Vitamin D is made naturally through exposure of sunlight. A sufficient level of vitamin D in the body is important for bone and muscle health protection. Lack of vitamin D can result in conditions such as rickets in children, bone and muscle weakness in adults and increase the risk of falls in the elderly. The relevant national bodies recommend that all age groups take a supplement providing 10 micrograms (400IU) of vitamin D a day, between the months of October to March. For full details, please see below:

For individuals who are in a higher risk group for vitamin D deficiency, a daily 10 microgram vitamin D supplement is recommended to be taken all year round. This includes people who:

  • Have low exposure to the sun
  • Reside in care homes
  • Cover up most of the skin when outdoors
  • Have dark skin, for example, African, African- Caribbean or south Asian backgrounds.

Greater importance has been placed on vitamin D supplementation this year because individuals have been spending more time indoors or shielding due to the coronavirus (COVID-19) pandemic and may not have made sufficient vitamin D. Since it is difficult to obtain vitamin D from foods, it is recommended to take vitamin D supplements as per the recommended guidelines.
