You are at a store and see this:Women's Ultra Mega® Energy & Metabolism Vitapak® ProgramOnly $45 for a 30-day supply! Look at the supplement label below, focusing on the B vitamins for energy production. Predict what will happen if you consume this supplement.

THIS IS NOT THE EXACT ANSWER!! Explanation: There are a couple of problems with this supplement. 1. Most people eating a normal diet get plenty of these nutrients, so adding more (over the RDA) is not needed. 2. As water-soluble vitamins, any excess that a person consumes (and this would all be excess) gets excreted in the urine. You may hear people say that vitamins just make for expensive urine; here it's definitely true! But people who take this vitamin package may experience feelings of energy, but they're completely unrelated to the energy vitamins. What's giving them energy? It's the caffeine pill that comes with these vitamins--see below. This is more than the amount of caffeine that you'd get from 2 cups of coffee!
