Ideal for larger bottles and longer sessions, GU tablets will see you through intense or prolonged training, writes nutritionist Rob Hobson.
Gu Hydration tablets contain a basic mix of electrolytes, but all that’s essential. The sodium content of each tablet (320mg) is enough to support adequate hydration and ward off hyponatraemia during moderate to intense, prolonged exercise. It’s one of the best electrolyte drinks that’s suitable for all types of exercise, though probably not be required for sports that don’t include a significant degree of sweating.

GU Hydration Tablets benefits
I enjoyed the flavour of these electrolyte tablets, which have a nice tang but may be a bit too intense for some people. You only need one tablet to mix with 750ml of water – that’s a large enough serving to get you through a moderate to intense training session. On test, I found the tablet combined well in water and didn’t require any additional shaking to combine.
The tablets are sweetened with a combination of sugar and stevia, although the sugar content is minimal. I also love the fact Vitamin B6 has been added to promote the transport of electrolytes in the body and for its role in energy metabolism and maintaining a healthy nervous system – although it’s worth noting, vitamin B6 is rarely lacking in our diet.
The packaging is convenient and can easily be thrown into your kit bag or pocket. However, they are only 12 tablets per tube so I’d recommend ordering in bulk. At 55p per serving for the multipacks, they are pretty good value, especially as you dissolve each tablet in 750ml. Plus, there are four varied flavours to choose from – lemon and lime, three berries, orange and strawberry lemonade, so there’s bound to be one you’ll enjoy.
