An analysis of biologically active additives in the form of fat-soluble vitamins in the territory of the Russian Federation

Dietary supplements are intended for use by generally healthy people to compensate for nonclinical hypovitaminosis and to prevent a number of diseases. Dietary supplements containing fat-soluble vitamins are sold in the Russian Federation both through the pharmacy network and via the Internet. In online sales, consumers are usually not informed about the intake dose, timing, indications and contraindications for consumption of vitamins. Searches were conducted across databases, using multiple search terms for each type of vitamin, to find medicines and dietary supplements for fat-soluble vitamins. Within the Russian Federation there is no uniform format for description of fat-soluble vitamin preparations, including the names and amounts of the active substances. In a number of dietary supplements, the content of fat-soluble vitamins exceeds the recommended maximum daily intake; for vitamin D by as much as 16.7 times, for vitamin E by as much as 2.7 times. Dietary supplements of fat-soluble vitamins with a high content of active ingredients are widely offered online. It is necessary to improve the legislative framework and its implementation to increase the degree of consistency and safety of dietary supplements for the consumer.
