Many people know the benefits of calcium, but it is not absorbed by itself and "works" only in tandem with vitamin D3. But why magnesium and zinc are needed is probably not known to someone. Yeah, I'm not very good at it either. So I had to turn to the all-knowing Internet. It turned out that magnesium is the most important element for the heart! It also normalizes blood pressure and participates in the activity of the nervous system. It is also needed for those who have problems with the respiratory system - and this is exactly my option. I have already written about my allergy and that recently it has begun to turn into a state of asthma, from time to time it was because of the allergy that I began to suffocate. So, why do we need zinc?
