What types of supplements? Powders? Pills? Are you taking them multiple times a day?
If I'm traveling I use small tupperware containers for powder and zip lock bags for pills. Nothing special, but it works well.
I guess everything really! Right now I have a sock drawer dedicated to my aas/ancilliaries, a bar fridge in my bedroom for peptides, energy drinks, shakes, etc, but I seem to have bottles of pills everywhere and that kinda sucks.
I store my extra bottles in plastic drawers in my closet but I typically have a lot of bottles that I use daily. I tend to leave them out on my dresser so I don't forget to take them but I need a better system especially since I'm about to be using more. I generally take my morning supplements and then bring all of the supps to work with me that I need in the afternoon. Mainly looking for a better system at home for all my pills/staples. Besides vitamins and minerals, I also use a lot of nootropics daily, so my pills take up more space than anything else.
