hey all,

so i've been doing fine on adderall 20mg a day, it's been quite effective to help me study for a week. however on the same day that i've just added magnesium and a multivitamin to my daily regime, adderall has completely stop working for me. i don't get that subtle concentration boost at all. i feel as though that the tablet just passes through my body unabsorbed or something. thinking my body needed to adjust, i continued supplementing adderall and mag and the multivit for a total of a week and the adderall still doesn't do anything for me for all those 7 days. i then took a week off of taking any supplements or adderall at all, then started the adderall without the mag and multvit, and now it works like normal..

my doc doesn't know why supposedly the mag or the multivit has nullifies the adderall, does anyone have any ideas?

It could be the vitamin C in the multi-vitamin. As for magnesium, I thought it's supposed to have the opposite effect when taking adderall though. Try taking the multi at night?

too bad you actually want to keep taking vitamins , especially vitamin c.
