hi there no probs
mag and potassium are a good combo but mag phosphate is an inorganic salt and it's listed with magnesium oxide which while high in elemental magnesium, is still difficult to absorb and quite frankly gives me the trots :S although i have not tried mag phosphate myself.
magnesium glycinate is an organic salt chelate, and so is magnesium citrate. i have tried both and in terms of absorption i found glycinate way better, although i still use both products but for different reasons.
as for the supplement, those amounts are negligible and i don't see anything terrible listed - even though they are probably not using the right vit E in that one, the amount is sooo low. here's my regular multi vitamin so you can compare: http://www.progressivenutritional.com/e ... women.html
(you have to click on the ingredients tab to see the detailed list)
as for zinc i was suggesting you may have depleted levels. a test could be good. if you can, see if the doc will go for these tests:
serum vitamin d3 (the 25(OH)D3 form) nmol/L
serum magnesium mmol/L
serum zinc umol/L
serum copper umol/L
serum vitamin b12 pmol/L
that should be a good start
if doc won't go for all that, try for serum zinc and serum magnesium.
anyway yes i think taking zinc is probably needed. (but with certain things, i am just not keen on ppl 'flying blind' and supplementing without having a handle on their levels).
all those foods you listed are solid magnesium depleters... you can cut down but cheat a little, as long as you can get your hands on a proper magnesium supplement that won't send you running for the loo!
