i am looking for a reaction with water that will make it carbonated

The easiest is dry ice or gaseous CO2 in water:
CO2 + H2O <=> H2CO3
increased pressure tilts the equation to the right, as does lower temperatures above freezing.

Sodium bicarbonate is pretty highly carbonated. In fact simply raising the temperature of a solution will cause the excess CO2 to be released.

does this stuff use sodium bicarbonate http://www.keysupplements.com/products/1264.htm

It's possible it uses either sodium bicarbonate, or calcium carbonate, or even potassium carbonate, or even a mixture. Any carbonate or
bicarbonate, with the acids mentioned will fizz and make a carbonated liquid.
Alka-Seltzer is an example of this. Funny as it sounds, a small piece of Alka-Seltzer in a liquid will tell you if any water is present. It is very
sensitive to trace amounts of water.
The generic phrase of a soft drink ( in the US anyway) as a "soda" refers to the generation of carbonation by adding phosphoric acid to
sodium bicarbonate. An older reference refers to them as 'Phosphates".

I don't think enough sodium is used in soft drinks to carbonate them, especially the low sodium ones. For sure it's all stored under
pressurized CO2, so they do it directly.
