Instant coffee dissolves perfectly into cold water. I did not know this. I never expected to know this.
Prescribed drink for returning some bodily ADP to ATP: cold coffee and D-ribose (5-carbon chain sugar). Tea not suitable as caffeine source, as tannin interferes with the chemical reaction. D-ribose is destroyed by cooking, so to play it safe until one has better medical advice about the destruction of D-ribose in boiled water, cold water coffee it is.
8.8 pounds of D-ribose costs AU$600.00 One does not wish to waste it. But it is absorbed more readily in liquid form, and it tastes funky despite being sweet, so one is not going to eat raw teaspoons of it.
One's ATP, necessary for the energy to run EVERYTHING, is being destroyed, instead of being recycled within 10 seconds of use by one's mitochondria, as in a normal healthy person.
