Not calcium, but potassium. No mistake. This is a separate story.
Well, that is, everyone remembers that coffee has a diuretic effect, and diuretics can excrete potassium. Potassium is needed for the heart and muscles, so it would be better not to lose it.
We have already discussed different effects of caffeine. And then there were questions about potassium. In fact, athletes have taken care of potassium for a long time.
Athletes need potassium for their muscles and heart, and they also use caffeine as the simplest and proven drug.
And athletes are also afraid of the diuretic effect, from which they lose precious water. Without water in sports, it is easy to get dangerous dehydration.
And athletes are also afraid that the diuretic effect can irritate anti-doping experts, who really do not like diuretics in sports. Athletes sometimes remove doping residues in this way.
So the athletes were very interested.
They even planned and conducted scientific research for this business. It turned out that for a person who is not accustomed to coffee in the first couple of days, something may be slightly removed there, but this effect is so short-term and weak that it can be neglected.
It turns out that neither potassium nor water is practically lost, and the diuretic effect of caffeine will only matter for those who have a weak bladder and who often have to go to the toilet. So much the better not to abuse.
It is also rumored that coffee as a plant-based product itself can be a source of potassium. So there will even be an additional benefit.
What? About calcium? Yes, coffee can sometimes make bones weak. This only manifests itself with the regular use of large servings of coffee by women of age, provided that they eat little calcium. That's when osteoporosis really gets worse, and you can get a fracture.
So you don't have to worry about potassium, but don't forget about calcium.
