sucrose 24g, taurine 800mg, caffeine 0.05g (not much) inositol 30 mg, B3 20mg, D-Pantothenol 5mg, B6 3mg, citric acid .99 g That's the contents of a 150ml bottle of Kratingdaeng. If you think the silver can crap is strong....don't even smell this stuff. I can't see someone freaking out on either one. When I was in Thailand I regularly drank 10 or more bottles a day. Not to say that someone couldn't have a reaction between this and some other substance that they consumed.
