Ha, so there is an amazing Swiss startup (that took some wrong steps), KA-EX. They make an isotonic drink (btw Isostar is/was also Swiss), and my personal sample and annecdotal news from my friends, well it works (worked). Super easy recovery, hangover cure too. But lately they moved onto drinks with Caffeine added, stopped their original product, and it's not as effective. But well, there are some Swiss startups doing just fine.
