GU hydration tabs ingredients nutrition facts

While GU Tabs contain the top two electrolytes, sodium and potassium, it's missing some of the other key ones. 
Adding electrolyte minerals like magnesium, phosphorus, and chloride — would make a more complete electrolyte replenishment.
In conclusion of this review of GU Hydration Tablets, we think it's a good product but with a few downsides — including added sugar, inflammatory safflower oil, synthetic vitamins, and limited electrolytes.

We believe Zaca is a more robust and powerful hydration alternative to GU tablets.
