Adding - 1/2 tsp of salt is 2.5 grams of which it is 1 gram of sodium. G2 - 435mg sodium, 120mg potassium; normal - 400mg, 100mg.
Note that the label says it contains 21g sugar, 150mg sodium, 35 mg potassium - per 12 fluid ounces. Multiply by 2.66 if you drink the whole bottle.

Potassium (mg) 0 120 100 93 780
It's striking how similar the regular Gatorade and Powerade are. Also, the powerade.com nutritional info site is "down for maintenance", had to search elsewhere: http://archive.is/2018.02.22-160258/https://www.powerade.com.... They have the Coca-Cola logo.gif on the site, but unfortunately no animated orange construction barrels.
Edit: Added Pedialyte
Gatorade has glucose (aka dextrose, the same sugar as an IV bag) while Powerade has high fructose corn syrup.
Glucose can be used directly by your cells while fructose is metabolized in the liver first. So for quick relief from dehydration I choose Gatorade.
* Glucose = 100% dextrose
* table sugar / sucrose = 50% dextrose
* high fructose corn syrup = ~40% dextrose
I have seen in stores sodium-free salt, and reduced-sodium salt, which both substitute potassium for the "missing" sodium, which can be a source of potassium if the added benefit is worthwhile.
So for 32oz, that 986mg sodium, and 24g sugar, which seems spot on to the articles recommended ratios.
Hydration is no joke.
