> Magnesium Oxide (the most common from in cheap multi-vitamins) is very poorly absorbed and probably useless I read the opposite, the others you absorb so fast and get peed out (resulting in high magnesium in urine) while magnesium oxide gets absorbed the most since it is so much slower. But I can see everyone saying the oxide one is bad due to it not increasing magnesium in urine as much, but you don't really want to increase magnesium in urine you want to increase magnesium in your body and that is done better when absorption is slow since you don't want it all to go to your urine.
