In the United States, the current recommended daily intake of 800 IUs vitamin D is based on the minimum amount to protect against bone disease. However, an upward revision of this guideline is now being considered in light of current research, especially new research regarding immune function. This research suggests serum vitamin D levels should be in the range of 32-80 ng/mL 25-hydroxyvitamin D.?
The amount of vitamin D needed to achieve minimum vitamin D sufficiency – generally recognized to be a blood level of 32 ng/mL of 25-hydroxyvitamin D – depends on many factors and varies from individual to individual. Thus, the requirement for vitamin D supplementation should be individualized. Either D-1,000 or D-5,000 maybe be ideal to maintain an optimal level of vitamin D in healthy individuals.*
