https://youtube.com/watch?v=Vyc8TAyeYFgwww.videocyclingclub.com A Review of the High5 Zero Sports Drink Tabs. I've been using the High5 zero sports drink tablets for a few weeks now and I rather like them. While on a longer ride it is very easy to become dehydrated if you don't drink enough. This is because you sweat and loose moisture, salts and minerals from your body. Keeping hydrated is actually very easy simply by taking taking a drink every ten to fifteen KMs or so. Water isn't bad but if you want to replace the salts and minerals as well you will need an electrolyte drink. The High5 Zero electrolyte sports drink tabs come in five different flavours, they are easy to use, nice and convenient and, best of all, are zero calories and zero sugar.
