Magnesium supplements I recently started taking magnesium supplements for anxiety, better sleep etc. However I was only able to find brands with higher or almost completely magnesium oxide. Is it just gonna pass through the system without being absorbed or if I supplement my diet with vitamin B6 and B12, which is get through a fruit smoothie i drink, will it get absorbed? my question is should i go and try to find a more absorb able form, or will this be fine if i take those vitamins with it? And also wondering what the ideal time to take it is, for getting the best results!
