Are you getting enough vitamin D?

Lucinda Harms, RPh, is the director of pharmacy at CarePro Compounding and Advance Health.

My recommendations for vitamin D dosing have definitely changed over the last couple of years.  My current recommendations include what is listed below during the winter months.  During the summer months, if tyou are outside at midday, you could either skip your 5,000 IU tablet that day or else drop your dose to 2,000 IU daily for those months if unprotected sun exposure is a regular occurrence.  It works out quite nicely to suggest that you purchase 2 x 5,000 IU vitamin D yearly, which covers 200 days/year.  This should cover from about September through April.  Then switching to 2,000 IU daily during the rest of the year.    

Here are the most recent dosing recommendations from the Vitamin D Council.

Based on the body’s indicated daily vitamin D usage, Vitamin D Council recommends the following amounts of supplemental vitamin D3 per day in the absence of proper sun exposure. Due to the variable response, these are only estimated amounts.

  • Healthy children under the age of 1 years – 1,000 IU.
  • Healthy children over the age of 1 years – 1,000 IU per every 25 lbs of body weight.
  • Healthy adults and adolescents – at least 5,000 IU.
  • Pregnant and lactating mothers – at least 6,000 IU.

Additionally, children and adults with chronic health conditions such as autism, MS, cancer, heart disease, or obesity may need as much as double these amounts.  I would recommend that they be tested to see where their levels of 25 hydroxyvitamin D are before going above 10,000 IU daily.

In good health,

Lucinda
