Pints of Guinness were served to blood donors at Pelican house in Dublin and as evidenced by the way the droplet sank ball-bearing-like during this particular very occasional consumer's pre-letting anemia test must have proved a very high source of iron - and apparently to the extent that pregnant women were often recommended a daily dose also. Furthermore another pint the next day rather than a fizzy orange drink was more effective in quelling nauseau caused by its own enthusiastic over-consumption. A veritable panacea therefore.

It's got electrolytes.

Brawndo's got electrolytes ...

I think that Lucozade was originally actually made as a good way of giving people energy while they were sick. Whether that was actually a good idea, I have no idea.

And yet any time i ever have a bad hangover, my body cries out for Lucozade.

That's to be expected. Lucozade and similar products are packed with electrolytes. It's basically water, salts, flavouring, and a ton of sugar.

For the record regular Lucozade is straight glucose with no caffeine.

So yes it is sugar, but 'sugar' as in sucrose, which is glucose and fructose.

Pretty sure there's caffeine in there too. It's like orange sugar soda.
