5000 IU daily for vitamin D deficiency

How much vitamin D3 do you need each day if you are deficient? A new study reports that 5000 IU daily for three months will get you back on track.

Vitamin D deficiency is commonly treated with large weekly, monthly or yearly doses. However this is not natural, vitamin D should be made each day in smaller doses in your skin after exposure to sunlight.

A recently clinical study set out to find an optimal daily dose of vitamin D for treating deficiency (a blood level less than 50 nmol/litre)

The study compared a dose of 2000 IU or 5000 IU of vitamin D3 daily for 3 months.  Of the people taking the 2000 IU dose, 45.4% made it to a healthy range (above 75 nmol/liter) while in contrast 93% of people taking 5000 IU successfully treated their deficiency.

So, if you are vitamin D deficient try 5000 IU of vitamin D3 daily for 3 months. It’s safe, and very effective.
