What I was saying is, vitamins are way more complex
and each one has way more than just one function, so to say B
vitamins are
energy producing, some are, but a stress B vitamin containing all the ones you mentioned helps relax the system, obviously, again, not stimulating. As for spreading the vitamins through the day, no, it doesn't cost anything more if you buy good quality vitamins. A good multivitamin requires you to take several pills a day, so you just take them a bit at a time.
