Sports drink for Low Carb cycling

Here is a copy of a post at forum.lowcarber.org where I have commented on regarding sports drinks

Any ideas for a suitable water bottle drink for a long bike ride? 
As opposed to bought electrolyte replacement powders etc.

My reply:

Hi jludders,

Yep, those shop-bought electrolytic replacement drinks are quite expensive, aren’t they? I always question whether they actually do anything significant that you can’t do with something as simple as a few drops of lemon juice in water and a sprinkle of salt on your tongue.

When you think about what we lose when we’re exercising, it really is down to basically, liquid and salt. Now providing those two are being replaced, you should be fine.

Hope that helps,

Mark
