These folks are saying that taking vitamin supplements may increase risk of death. They neglected to take into account the utilization of primary care and specialists in this population. I would say that many people are trying to take their health into their own hands with use of supplements and activity, at the expense of regular care. This is pushed partly by lack of trust in our healthcare system and providers, and largely by the cost of care.
So, with the increased supplement use, did doctor visits go down? Were these people taking supplements in lieu of prescription medications that would have helped them and were necessary?
