Thanks Lotus for the answer!
Unfortunately it doesn't seem to be a decent supplement of calcium citrate because the best in price and calcium amount are all using calcium carbonate. Also Magnesium Malate doesn't appear on the supplements i've seen, but rather it is replaced by Magnesium Oxide.
Good thing is that it doesn't seem to have any PEG or titanium dioxide, yellow #40, etc etc.
I fear i might not have fully understood what you were trying to say here, i apologize. I still feel confused and unsure on whether i should base my choice.
