This was this weeks threaded discussion in Vitamin & Mineral Metabolism:
The B-vitamins are considered energy vitamins by many. In fact, marketers refer to energy when these vitamins are included in products. Discuss the legitimacy of referring to these vitamins as the energy vitamins. If you agree with this term, give evidence for the claim. If not, give good reason why this claim should not be used.
My post focused on the fact that b vitamins do not supply energy.
Carbohydrate, fat and protein supply the fuel for energy.
