Vit. D pills of little benefit - Dr. McDougall, March 2010

ENDING:
Pills Are the Last Choice to Raise Vitamin D Levels
Some people are unable or unwilling to get outdoors or unable to afford to use a tanning bed. The elderly and infirm confined to nursing homes, long-term care facilities, and their own homes are at an especially high risk of developing deficiencies. Adequate oral daily supplementation is as little as 200 IU of vitamin D for healthy adults not exposed to sunshine. Darker skinned and elderly people require more. Common recommendations are for 2000 to 4000 IU daily of over-the-counter vitamin D to correct vitamin D blood levels. Signs of vitamin D toxicity appear only after daily doses exceeding 10,000 IU. (1 mcg vitamin D [cholecalciferol] = 40 IU). Vitamin D2 is as effective as vitamin D3 in maintaining circulating concentrations of 25-hydroxyvitamin D (34). Remember the topic of this newsletter: The benefits from taking pills are very limited and there are adverse side effects. The lesson is: Natural is best when it comes to food and sunshine.

I am lucky and get my D from sunning in my backyard, near Santa Barbara CA! It gets addictive. Started in Nov. '09, tested for first, only, time in April '10 -- level was 43, want above 20 min., above 30 for better results. Note that these were winter months -- when the sun rays are the weakest.
