"For this reason, one of the objectives of our work was to check whether products containing vitamins D and K meet the quality requirements. ![]() "Given the vast amount of dietary supplements available around the world, quality control measures appear to be insufficient and label claims may mislead consumers," say the authors. They also found that based on the results obtained, there were significant deviations in the content of vitamin K2 and D3 in the tested supplements to that stated on pack. The obtained results allowed the team to conclude that their methodology was reliable and met the requirements for analytical procedures used in the analysis of medicinal products. The recent study was conducted by researchers at the Jagiellonian University Medical College, in Poland, to develop optimal conditions for the qualitative and quantitative determination of vitamins D2, D3 and K2 in dietary supplements available in various forms, using thin-layer chromatography with densitometric detection.Īs a result, the methodology for analysing the content of three vitamins from various matrices was developed, optimised and validated in accordance with ICH requirements. There is an increasing interest in supplementing the diet with various vitamins, especially vitamin D which is widely recommended to be taken during the winter months. ![]()
