Vitamin D interestingly is both a vitamin and a hormone. Infants up to the age of 12 months require 400 international units (IU) per day while children and adolescents require 600IU per day. There are many foods in the market fortified with Vitamin D ranging from milk, orange juice, cereals and yoghurt. Oily fish like salmon and canned sardines are also a source of Vitamin D. Vitamin D can also be synthesized by the skin through sunlight (UV rays) exposure. However, due to the unpredictable sunlight exposure and the risk of skin cancer with prolonged UV exposure, Vitamin D is best consumed from the diet.
