We read with great interest the article by Domański et al. describing the results
of an analysis concerning vitamin D content in dietary supplements available in EU
countries. In our opinion, the article raises a very important issue, which is the
lack of regulated standardization of dietary supplements in terms of the contained
doses of vitamin D.
Recent data collected during a large observational study report that about
40% of Europeans are vitamin D deficient, and 13% are severely deficient [2].
A significantly reduced vitamin D level can cause serious metabolic disorders,
leading to deregulation of calcium-phosphate metabolism, increased risk of
infections, endocrine disorders, or increased risk of depression. With increasing
public awareness of the potential consequences of vitamin D deficiency, the use
of vitamin D-containing supplements has been steadily increasing in recent years.
