i get kirkman brand magnesium glycinate from a local fairly mainstream pharmacy - but i don't think kirkman is your usual pharmacy fare like jamieson or whatever.
i have used various things for magnesium citrate, and that one tends to be one i get at more of a specialty nutrition store. for example 'Now Foods' and 'Natural Calm'.
personally, i can take citrate whenever, but i have to be careful with glycinate.
some sources eg klenner say to take magnesium *after* eating BUT i take glycinate *just before* food in order to make the food push the magnesium down into my intestines ASAP. if it hangs out in my stomach, it relaxes my LES and voila, acid reflux.
with the citrate form, i can take it after eating, or on an empty stomach, and then i could go lie down for good measure, with no problems. it seems that it just doesn't absorb as readily, in my experience.
i like to have both forms on hand. i think they will both help you cope with the stress and anxiety of your busy exciting times! a nice hot mug of natural calm in the evening can be very soothing too, and it comes in a bunch of different flavours.
as for which thing to take with which meal, i think if you take zinc with a seedy breakfast you'll be okay. alot of nuts and seeds -including pumpkin- naturally contain both magnesium and zinc; your body knows how to handle it
yes iron and zinc compete, and magnesium and calcium compete, etc, everything seems to influence everything else in some way! when it comes in food, your body knows how to work it out. with supplements it's a little different. for example if you take just iron it shoots up fast, but your zinc level can drop. if you take just zinc that shoots up fast, but your iron can drop. if you take both, both levels climb, but just more slowly than they would taking either alone. at the end of the day, when you're taking higher doses than those occurring in food, you just have to try for balance.
if you are concerned about iron and magnesium together, then if it works for you, you could take iron and magnesium at separate meals. you can take the iron with vitamin C to optimize its absorption, and then the magnesium on its own at a diff time of day.
clear as mud??? 7:)
good luck with all your final arrangements, it's going to be awesome and you'll be cool as a cucumber! keep us posted ttfn
