Vitamins are active compounds with various structures and chemical properties that are essential for our health and normal functioning.
The maximum daily intakes of the fat-soluble vitamins (vitamin A, D, E, and K) are strictly regulated in many countries because they are easily stored and accumulated in the human body, which may lead to hyper-vitaminosis and subsequent adverse effects. Moreover, most of the fat-soluble vitamins are not stable and decompose when exposed to various factors.
The vitamin content in food supplements may decrease during storage, which has already been demonstrated in practice.
For all food supplements products is crucial that the vitamin content is evaluated at all stages of the product manufacturing and storage. Therefore, the fat-soluble vitamin content must be controlled by the manufacturer in order to provide safe and high quality products throughout the shelf life of the product.
