Vitamins are considered nutrients essential for the day-to-day running of our bodies and to support normal energy yielding metabolism.  Vitamin C and B-complex vitamins are  water-soluble, so they are removed from the body with urine and sweat. Because we can’t make them ourselves (with the exception of vitamin B3), so they need to come from our diet or  supplements, like this one. Vitamin D belongs to the group of fat-soluble seco-sterols. The two main forms are vitamin D2 and vitamin D3. In addition, vitamin deficiencies occur with intense physical effort, stress, irregular meals, etc. In this case, support with vitamin supplements is recommended. Our special product contains a vitamin complex that synergistically supports immunity and adds energy.
