It's not necessary to take with food. The piperine in Stoked will aid/enhnace the absorption of phytonutrients from foods or other herbal supplements though.
Ideally, he split doses are taken 8-12 hours apart. I personally wouldn't inconvenience myself trying to take it one way or another and would just strive for consistency. Some do prefer to dose pre-workout though.
I know, I probably didn't answer your question, lol.
