Hydration tablets

I like the High 5 Zero, but I have found these to be better http://cgi.ebay.com.au/ws/eBayISAPI.dll ... 8932wt_906" onclick="window.open(this.href);return false;

They work for me and great tasting.

For any newbies reading this they are not hydration tablets, they are electrolyte replacement tablets. Hydration can only come from water and when youexercise a lot and only drink water you need to replace electrolytes using the above products mixed with water.

Great comment. Don't forget that you lose salts when you sweat so it's good to drink the odd energy drink, juice, soft drink or whatever instead of plain water if you're really going for it. You can get emergency hydration tablets that are meant to be used with water for people with osmotic imbalances caused by over exertion - they basically contain a few salts.
