Information and this topic was obtained from a database created by the US government's Office of Dietary Supplements in cooperation with the National Library of Medicine.
"We compared the doses of individual vitamins declared on the labels with their recommended daily dose" - the main author of the work Michael Madden explained to Reuters.
This is the dose that the average person of a given age group should consume everyday to meet the body's needs. In the US, it is established by the Institute of Medicine (IOM), and its recommendations are an independent recommendation for policy makers.
The analysis concerned 9 vitamins in preparations for the youngest children and 14 vitamins in preparations for the older group.
It turned out that only vitamin D content was consistent (in preparations up to 1 year) or lower (in preparations for older children) than the recommended daily dose. In addition, lower choline content was found in supplements for children 1-4 years old - 13%. recommended daily dose.
However, the doses of other vitamins - i.e. vitamins A, C, B1 (thiamine), B2 (riboflavin), B6, B7 (biotin), B12, E, K as well as niacin, pantothenic and folic acid - exceeded the recommended daily intake. For example, the biotin content corresponded to 936 percent. recommended daily dose in preparations for a group aged 1-4 years and over 550 percent. in preparations for the youngest children.
