Vitamins for energy?

Coffee is a vitamin

I take a One-a-day women. Any other suggestions for energy?

No such thing, you don't need one vitamin or even a small group for energy you need the full complement of macro and micro nutrients plus enough overall calories. You can do more harm than good randomly supplementing with no regard for toxicity or how nutrients work synergistically and in opposition. Just eat a consistently balanced largely wholefood diet - nine servings of fruit and veggies in the full rainbow of colours, three servings of dairy a day, protein and healthy fats little and often including oily fish regularly, plenty of mineral and fibre rich foods (beans, lentils, nuts, seeds). Don't skip meals, try to get restful sleep and be physically active with your 10,000 steps daily, don't smoke, limit caffeine and alcohol. There is no magic, just healthy living.

I take Rhodiola and love it.
