Now is the period when our body has stopped receiving vitamins from vegetables and fruits, because by spring there are practically none left. Our body immediately reacts to this. Drowsiness, general fatigue and malaise, bad mood, and irritability appear. Many who have experienced these symptoms try to prevent their body from getting into this state in the future, resorting to the help of tablets with which pharmacies are overflowing, and, more recently, many grocery stores. In order to interest the buyer, pharmacologists manage to combine different vitamins and microelements in one package. On the one hand, this saves both time and money for consumers. But the point of this article is not to convince you to take this or that drug, but to teach you how to take any mineral supplements and vitamins correctly.
