We all know our skin makes vitamin D during sun exposure, so you’d think that most of us here in Hawaii would have plenty of vitamin D, right? Wrong. A study done on prototypical surfer-dudes in Honolulu, titled: Low Vitamin D Status Despite Abundant Sun Exposure (Binkely, 2007) found that, amazingly, more than half (51 percent) had less-than-optimal blood levels of vitamin D and were therefore putting their bodies at risk. At risk for what? Low vitamin D has been associated with overweight and obesity, as well as a variety of serious medical conditions, including cancer, heart failure, mental illness,…

Current recommendations are for 200-400 I.U. per day, depending on age. But Dr. Hollick suggests that our true needs may be on the order of 2,000 I.U. Since studies show that most people consume very little D and don’t get enough from sun exposure, there is a nearly universal shortfall of vitamin…
For years I've avoided putting my patients on fosamax and related drugs for "bone health," because according to the package insert, these drugs don't make bones healthy. They prevent part of the natural cycle of bone growth, called bone resorption, and by doing so make them denser looking on bone scans.
