Longer intake of vitamins can be made only by appointment specialist in cases where we are talking about people who are constantly carrying a heavy physical load (e.g. athletes, miners, metallurgists), or living in areas with harsh climatic conditions – in the far North or in the regions equated to it.
Take vitamins preferably in the morning and in the afternoon, ideally at Breakfast and dinner for better absorption. If you get a regular and varied diet, including foods rich in vitamins, and good feel, take vitamins is only appropriate in cases where the laboratory tests revealed the lack of any specific item in your body.
