Those ‘energy drinks’ have weird ingredients in addition to sugar......
For instance Monster:
The ingredients include carbonated water, sucrose, glucose, citric acid, natural flavors, taurine, sodium citrate, color added, panax ginseng root extract, L-carnitine, L-tartarate, caffeine, sorbic acid, benzoic acid, niacinamide, sodium chloride, Glycine max glucuronolactone, inositol, guarana seed extract, pyridoxine hydrochloride, sucralose, riboflavin, maltodextrin, and cyanocobalamin.
Here’s the dirty little secret about “energy drinks”...
They are mostly just weird flavorings, Sugar, and carbonated water... with Caffeine and B vitamins.
The B Vitamins and Caffein simply stimulate your system, so you absorb the sugar even faster...
But its the sugar thats the real problem... though any stimulant can cause issues too in large enough doses.
