I would be really careful with KCl supplements and salt substitution. Back when I worked in medical research we used IV KCl as our euthanasia solution for years, because the better alternative is controlled (pentobarbitol). The stuff vets use now is much nicer. It really ODs the animals so they lose consciousness and stop breathing. IV KCl induces heart failure and did not look pleasant at all.
