The Forgotten Vitamin     

Vitamin D has recently been studied and found (in conjunction with adequate amounts of calcium, 1200-1500 mg/day) to decrease the risk of developing and dying from most cancers.  It protects from impaired glucose (sugar) tolerance, prevents cardiovascular disease, and improves balance and muscle.

There is always new information about taking vitamins.  How common is this Vitamin D deficiency?

-          Vitamin D deficiency is common 

-          40 – 90% of middle aged and older adults having below the recommended levels - 30 ng/ml.

-          Vitamin D is available only from supplements in milk and orange juice or the sun.

What is needed to get adequate amounts of Vitamin D?

-          Mild sunburn on arms and legs 4 days/ week (NOT Recommended)

-          20 glasses vitamin D fortified milk or orange juice.

How do I get tested for Vitamin D?

-          Your health provider can tell from a blood level of 25-hydroxyvitamin D

-          The levels should be between >30 – 80 ng/ml (the exact level may vary between laboratory)

How much Vitamin D do I need to take daily in a supplement if my level is insufficient or deficient?

-          2000 IU per day.

-          Make sure your supplement is Vitamin D3.  The only prescription Vitamin D is D2 and this is not a bioavailable form.

Depending on your levels your health provider may suggest larger amounts at first.  Vitamin D levels should be checked again in 3 months to be sure you are not getting too much Vitamin D.  Over 80 ng/ml is considered a toxic level. 

Talk with your Health Provider - ask for a level of 25-hydroxyvitmin D.
