You should base the dosage of Component 1+ 2+ 3+ on the element that is the least consumed. If the consumption of magnesium - Component 3+ is smaller than consumption of Ca and KH, you should base the dose on Magnesium. For example, if the consumption is 5 ml daily, you set it as base dose of Component 1+ 2+ 3+ and supplement the missing elements with Ca Plus and KH Plus.
