I agree, Lithium being a group 1 element along with Na and K are important in nerve function and signaling. I suspect the reason the "fizzy" seems to have a greater ammounts by mass than the flat version is that many of the Hydroxides peresnt will form carbonate almost instantly with the addition of the CO2 gas, and carbonates molecule per molecule are heavier than hydroxides which only contain an OH group.
