Rated 5 out of 5 by willyhc Keeps you going for longer! I've been using the High5 Zero tablets for over a year now and have used them when training at Judo, squash, swimming, football and running. A single tablet is perfect in 500ml water on a 10k run, or swimming and when training harder (squash or judo) I use 2 tablets. The flavours are great (not too sweet) and although there isn't a noticeable boost of energy, you realise that you can maintain your effort for longer and with more ease - in essence you have more stamina. They are that good that even my wife uses them now! They're also cheaper than most energy drinks, taste better and do more. 13 September 2012
Rated 3 out of 5 by claire63 Didn't notice much of a difference I drunk this in replace of my regular water when i go to the gym and although it tasted nice I didn't notice much of a difference in regards to energy or additional burn. 21 February 2013
Rated 5 out of 5 by Coliolli Perfect Hydration I've been using High5 tablets for several years as a great tasting way of helping me hydrate and provide energy for by road cycling and twice weekly spin classes. They helped me cycle from London to Paris in 2015 and to complete numerous 100m+ cycling sportives. I would not do any serious exercise without them. 25 August 2016

Rated 4 out of 5 by FodeBasingstoke Electrolytes Easy tabs to just chuck in your water bottle to get your electrolytes whilst doing sport or after your workout. Really like the taste of the cherry ones too. 12 August 2013
