How much vitamin D should I take? What are the vitamin D recommendations for adults in Canada? We get asked this question a lot!

With all of the different articles and recommendation groups, vitamin D recommendations can become confusing.  Luckily, we’re here to help. While we here at Ddrops cannot recommend dosing to your specific needs, we can provide you with the dosing information specifically for adults from a group here in Canada.

Health Canada recommends that all adults receive a daily vitamin D supplement of 600 IU to 4000 IU a day. This dose of the vitamin should begin at age nine and continue until age 70. At-risk groups include:

  • Pregnant women
  • Those with little exposure to the sun (ex: those who work inside)
  • Those who wear concealing clothing and/or sunscreen
  • Those with darker skin
  • Those who are obese
