GU Electrolyte Brew Tablets


GU Electrolyte Brew Tablets

Human Physiology 101 - water is a great way to hydrate, right? Well, yes and no. Water of course has the fluid you need because that's what it is - just fluid. Problem is once you start training and racing and drinking lots of water, your body starts using some of that fluid (in muscle contractions and for cooling for example) and gets rid of the rest through a few different mechanisms such as urination because it is just water - the body can store and use only so much pure water. Therein lies the problem - the more straight water you drink the more you lose - a self defeating endeavor if there ever was one. But you're supposed to retain that water to "stay hydrated", right?! What gives?

That's where electrolytes such as sodium and potassium come in - by their very nature they help your body retain the fluid it needs to function properly. That's why drinks with electrolytes are so important for proper hydration. They act as a catalyst to help your body retain fluid necessary for muscles to work properly so you don't lose all that valuable fluid. The Brew Electrolyte Tablets are fortified with a unique blend of electrolytes, and are a better form of hydrating than water alone. So where you may typically grab a bottle of water -- try Brew Tablets to retain the fluid you need to stay hydrated.

Electrolyte Tablets offer a convenient and fast way to enrich straight water (when Electrolyte Brew or an alternative may not be readily available). Ultimately the Brew Electrolyte Tablets are another offering from GU that help athletes keep variety in their sports nutrition regimes.

Using them with other GU products such as GU Chomps is as simple as swapping them for Electrolyte Brew an athlete should account for the lower calorie intake and possibly add an extra GU Energy Gel, Roctane or a Serving of Chomps (all roughly 100 calories).

Product consumed: Orange flavor Pros: No measuring required; great price; delivers excellent electrolyte superpowers! Cons: Uses artificial sweeteners, which has an awful taste in my opinion. The fizziness helps with the taste though. The fizziness causes pressure in the bottle that makes the liquid seep out however. That could get your bike messy if you don't have a good bottle.

while it took me a little while to get use to the flavorful but unsweetened taste, this stuff really packs a kick when i need it most. I have only tried orange, and i really like it now.
