No I never had to take any supplements with the coolers. All the vitamins are in the coolers. Everything. I’ve been told by my parents that the Coolers have calcium in it, the old stuff used to have it in, The Maximum XP powder drink. Referring to the coolers itself. The 1st day I didn’t like the taste too much but after cooling them in the fridge it doesn’t taste so bad at all. There was tang to the taste at first but now I don’t notice it.
