How much Vitamin D do I need to reach a desirable blood level?

Target Vitamin D Level: 100.00 nmol/L | 2885.00ng/DL
Amount of Vitamin D Needed to Reach Your Target Blood Level (including current intake):
-IU

Your weight, D3 levels and dosage.

As a general guideline, we recommend 1000 IU of Vitamin D per day for every 25 kg (55 lbs) of body weight.

 

•Taking 1000 IU daily raises Vitamin D levels by approximately 12.5 nmol/L (5 ng/mL).

 

For example:

A person weighing 68 kg (150 lbs) with a Vitamin D level of 37.5 nmol/L (15 ng/mL) and already taking 1000 IU/day would need to increase their intake to over 2800 IU/day to reach a target level of 75 nmol/L (30 ng/mL).

Someone weighing 90 kg (200 lbs) with the same current and target Vitamin D levels would require at least 3400 IU/day.

 

Note: Factors like being overweight or older can reduce the amount of Vitamin D in the bloodstream, so higher doses may be needed in these cases.
