Currently, there is an ongoing debate regarding how much vitamin D is adequate for each individual. Naturally, this amount is going to vary by age and other factors, but regardless, not many groups of researchers and physicians can agree on a set number.
In fact, older studies show that you need anywhere from 200 IU to 600 IU of vitamin D per day, with no more than 2,000 IU per day. However, as increased awareness of vitamin D deficiency diagnosis and conditions associated to vitamin D, it seems that these numbers are no longer adequate. It is possible that you may be required to take an additional 1,000 IU supplements in addition to the natural amounts of vitamin D you take in each day.
Again, because each individual situation is different, depending on medical conditions, age, weight, and ethnicity, discussing your vitamin D deficiency with your physician will be the only proper way to determine what level you should personally have. With that said, below you will find a chart that shows recommended intake of vitamin D per day, from one group’s opinion based on their research. This does not necessarily mean that this is what is right for you – talk to your physician.
The list below shows the average daily amounts of vitamin D that is recommended for individuals based on age. The Food and Nutrition Board, consisting of experts in the field of health and nutrition across the United States, developed the list. It is important to note that levels of vitamin D are measured in IUs, or international units.
AGE RECOMMENDED AMOUNT OF VITAMIN D
Birth – 12 months 400 IU
Children 1-13 years 600 IU
Teenagers 14-18 years 600 IU
Adults 19-70 years 600 IU
Elderly Over 71 years 800 IU
Pregnant and-or breastfeeding women 600 IU
