GU Electrolyte Brew

Compared to the impressive and unusual range of flavours that GU Energy Gels offer – Jet Blackberry, Lemon Sunblime, Vanilla Bean to name but a few – the range of options for GU Electrolyte Brew seems relatively orthodox. The raspberry, orange and lemon/lime flavours all do a fine job of adding a slightly tangy twist that cuts through the salty taste that defines most electrolytes, but only the Blueberry Pomegranate variety lives up to GU’s reputation for the unconventional. The flavours are all-natural and you can tell; there’s no bitter chemical aftertaste and all four are subtle enough not to be overpowering.

Taste of course is just one element (arguably not the most important one) when it comes to choosing an electrolyte option but GU Electrolyte Brew stacks up well where it really matters. Any electrolyte drink needs to replace the ‘body salts’ lost during strenuous exercise, when these are depleted the neuromuscular system’s ability to work effectively is compromised and the result (at least the most noticeable immediate result) is often muscular cramping. The raspberry, orange, lemon/lime flavours all include 327mg of sodium and 52mg of potassium, whilst the Blueberry Pomegranate ups the levels of sodium to 490mg, but cuts potassium to 40mg. For most mid-pack athletes the difference in ‘strength’ probably only amounts to marginal gains, but opting for the stronger Blueberry Pomegranate variety makes sense to TriGear under tougher, hotter conditions or if you are prone to suffering from the effects of dehydration.

In addition to sodium and potassium GU Electrolyte Brew includes a dual-blend of carbohydrates in the form of maltodextrin and fructose (‘complex’ and ‘simple’ carbs respectively.) They are stacked in a 2:1 ration, which is widely regarded as being optimal for sustained absorption – in other words, the carbs don’t just get ‘dumped’ into the system but rather are released over a period of him. The logic behind including carbohydrates – particularly a dual-blend – is that not only does it add a degree of energy that might otherwise come from a gel or bar, but it also helps  maximise the absorption in the stomach of both fluids and the potassium/sodium electrolytes. In short it can help rehydrate you quicker.

A single 34g sachet makes a larger than average 621ml drink – the rather odd volume probably the result of GU’s American heritage where it would make a far more round-sounding 21floz.

GU Electrolyte Brew is sold in boxes of 16x34g sachets, which mix with water to make 500-600ml drinks, at £41.60 or more reasonable but perhaps less convenient canisters containing 35 servings for £30.
