I would think that these new B vitemin supps for energy would only work well for those people that tend to live on fast food.
This is very true. B vitamins will give anyone a blast of energy if they are deficient in them. Someone already on a good food plan and multivitamin supplementation would get little from them, if anything. I don't know if any energy supps that don't contain caffeine or something similar like theophylline (tea) or theobromine (chocolate/cocoa) They are chemically very similar to caffeine, and someone caffeine sensitive would respond the same.
