You joke but… in tech school cantine, there was this “Vitamine Well” drink i took, since it was the only one that’s not too acidic (easily get heartburn). I had fissures in the corner of the mouth for years there and then it was suddenly gone. Later, i read that deficiency in some vitamin B variations (which were in that drink) causes said fissures. Since then i buy it once all one or two weeks and have no fissures anymore.
Long story short; they’re not entirely useless.
Maybe. But you would get far more out of a multivitamin then you would out of vitamin water. Vitamin water only contains water soluble vitamins for obvious reasons. But your body needs so much more than just those. Especially since most water soluble vitamins get pissed out of you before your day is even close to finished. I’m happy it worked out for you but if you had been taking supplements (or just an overall improved diet of non-overprocessed foods) all along, you would have not had the problem in the first place. What vitamin water does contain that you don’t find in supplements is large amounts of sugar and dyes. Hence the meme.
