You could take vitamin D or . . . 26. August 2011 William Davis (53) You could take vitamin D and achieve a desirable blood level of 25-hydroxy vitamin D (I aim for 60-70 ng/ml), or you could:--Take Actos to mimic the enhanced insulin sensitivity generated by vitamin D--Take lisinopril to mimic the angiotensin-converting enzyme blocking, antihypertensive effect of vitamin D--Take Fosamax or Boniva to mimic the bone density-increasing effect of vitamin D--Take Celexa or other SSRI antidepressants to mimic the mood-elevating and winter "blues"-relieving effect of vitamin D---Take Niaspan to mimic the HDL-increasing, small LDL-reducing effect of vitamin D--Take naproxen to mimic the pain-relieving effect of vitamin DSo, given a choice, what do most doctors choose? Of course, they choose from the menu as presented by the sexy sales representative sitting in the office waiting room. These medications, of course, are among the top sellers in the drug world, taken by millions of Americans and not just one at a time, but several per person. The Food and Nutrition Board of the Institute of Medicine, the panel of volunteers charged with drafting a Recommended Daily Allowance for vitamin D, says that you are already getting enough vitamin D, so don't bother taking any supplements and continue to wear your sunscreen. Wonder whose side they're on?I continue to be impressed that many of the conditions that plague modern people are little more than deficiencies peculiar to modern life, such as vitamin D deficiency, or the result of the excesses of modern life, such as consumption of sucrose, fructose, corn, and "healthy whole grains." I take 8000 units of gelcap vitamin D and haven't felt better.
