The truth about Vitamin D: How much vitamin D is needed by you?
In the year 2010, The expert committee that represented the institute of medicine’s had set a new dietary reference intake for vitamin D.
The committee of the institute of medicine set its recommendations based on the assumption that the person is unable to get Vitamin D from the sunshine and that this person gets adequate amounts of calcium.
The committee's recommendation includes getting the following amounts of vitamin D from diet or supplements taking into consideration the fact that the upper limit is not a recommended intake, but what has considered the highest safe level is the recommended amount for vitamin D.
* Infants ( age 0-6 months): The adequate intake of vitamin D for this category is, 400 IU/day; with safe upper level of intake being 1,000 IU/day
* Infants ( age 6 to 12 months): The adequate intake is specified as 400 IU/day and the maximum safe upper level of intake for this category is 1,500 IU/day
* Age (1-3 year): The adequate intake for this category is of 600 IU/day and the maximum safe upper level of intake is 2,500 IU/day
* Age (4-8 years): adequate intake of vitamin D is 600 IU/day, 3,000 IU/day being the maximum safe upper-level limit for intake
* Age (9-70): This category required an adequate intake of 600 IU/day of vitamin D, The maximum safe upper level of intake, 4,000 IU/day
* Age (71+ years): The adequate intake is 800 IU/day and the maximum safe upper level of intake of vitamin D is 4,000 IU/day
According to Boston University, this recommended amount is not enough. Michael Holick a professor of medicine at Boston University Medical center recommends a dose of 1,000 IU a day of vitamin D for both infants and adults unless they're getting plenty of safe sun exposure.
The American Academy in 2008 doubled its recommendation for 400 IU of vitamin D for breastfed infants. They have also recommended 400 IU/day of vitamin D for children and teens who drink less than a quart of vitamin D-fortified milk per day.
The Vitamin D Council has recommended an intake of 2000 IU of vitamin D daily for healthy adults. They are recommendation is higher for those who get little or no sun exposure.
