I use caffeine tablets throughout the day and have for years now. It roughly works out to 400mg to 700mg a day depending on whats going on. I use no other stims, energy drinks, or preworkouts. I am in good shape, single digit body fat, generally eat clean.
I'm wondering what support supps you would recommend to account for any vitamin/mineral deficiencies or hormonal/physical stress caused by the caffeine use?
What should I be taking daily to buffer and support? Recommendations would be greatly appreciated.
