We all know: Vitamins are important to keep well and fit. Therefore we are keen to supply ourselves with enough retinol (vitamin A), ascorbic acid (vitamin C), or calcitriol (vitamin D). While reading the news this morning, I stumbled across an article, dealing with the latter one. But as a matter of fact, it does not really matter which vitamin you think of. So, let’s just look at the vitamin D, bearing vitamins at all in mind.
In an article published by Süddeutsche Online, headlined The Fairy Tale of Lack , the journalist Christian Guth reports on a new study by Autier et al. published in Lancet Diabetes & Endocrinology in January this year. The authors therein state, after having done a meta-analysis of 290 studies, that the additional intake of vitamin D does not improve a patients well being. Only very few treatments, as a vitamin therapy for elderly people, seem to yield significant positive results. But all in all, it rather does not matter whether we swallow some vitamin supplements, or not.

However, I am not concerned with the consequences of additional intake of any vitamin whatsoever. As Bones (the famous ship doctor of the Enterprise in Star Trek) in my place would say: I am a PR-researcher, not a physician (well, Bones is a physician, but that is what he would say, if he was a PR-researcher).
Every year, the pharmaceutical industry generates six billion Euros in turnover by selling dietary supplements. Naturally, Germany is one of the biggest markets for those products. And when it comes to the health issue, people become attentive. Why not “investing” some money into one’s own health by buying some vitamin pills, and therefore, maybe, dodge the next cold you surely will catch during winter?
