I was taking that slow mag but I changed back to the oxide till I get the glycinde the doc ordered. Ok so let me understand is the rda for oxide or for magnesium? So when I take the 500 I only get 15 so I am 385 below the rda but some else I get from food or from my multi?Or is the rda for the oxide?When I get the glycinde I will switch to 120mg tablets and up to 10?Sorry if I am so lost.Is the only issue it cause bowels but no other harm?
