The real reason is more likely because we eat too much calcium.  The ideal per studies at pubmed.gov is actually 650 mg calcium, not more, and 1,000-2,000 i.u. vitamin D.  More vitamin D is ok (to a point).  More calcium can actually weaken your bones.  Extra vitamin D counteracts excess calcium so the most likely explanation is that too much calcium reduces your vitamin D and then you can't absorb and/or utlize calcium as well with depleted vitamin D.

The Japanese in fact get 300 mg calcium and have less osteoporosis than Americans.

So the best way is to get plenty of vitamin D and not worry about calcium too much.

Chia seeds and nuts are high in calcium though it's poorly absorbed.  Many of the veggie sources actually leech calcium from your body.  But because the oxalic acid in these veggies is so specific to calcium only and not other minerals, you can simply take calcium powder with them.  And unlike calcium powder alone you don't have to worry about being shorted on other minerals.  The veggies have plenty of these and oxalic acid won't bind to the other minerals.  Fortified foods are no different from calcium powde.  But again other nutrients including what's in veggies makes a bigger difference to your bones.

SURFER ok thats interesting.. I do in fact take a relatively high dose of Vit D3 daily. 
I tested borderline deficient and i LIVE BY THE BEACH and have alot of sun exposure.. What does that say...

What i wanted to do is to balance CALCIUM/MAGNESUM & PHOSPHOROUS... 
I have gum issues and apparently an inbalance of the above causes that. 

My diet isnt poor by any stretch but i admit i have pretty much the same salad everyday and suspect im not getting much by way of nutrients in it. I have started juicing carrot/kale/chard or silverbeet every day or two.

Surfer whats a good strategy to balance CA/MG & PHOS as above?
Thanks x

You probably have some problem absorbing vitamin D.  You could try applying vitamin D to your skin but that may or may not be any better for absorption.  You may simply need extra to combat the poor absorption.

There are tips in my sig thread for various nutritional combinations such as the one with nuts or the one with rice bran / brewerer's yeast / spirulina.  Juicing is nice too: spinach, parsley, cilantro, endive and/or watercress are the healthy ones.  "Superfoods" are usually BS.  The first 3 veggies and maybe the other two for all I know are high in oxalic acid though.  So you should enough calcium powder to get rid of the bitter taste goes away.  You usually need a masticating juicer for leafy veggies too.  For flavor (but not nutrition at all) apples are mainly sugar but they make a good sweetener.  Carrots too.  Cucumber and celery are mostly water and are good for diluting.  Likewise not really nutritious though, just to dilute strong flavors.  Kale, chard and beets aren't that special either.  There's a lot of misinformation out there.  Check here for the truth: https://ndb.nal.usda.gov/ndb/ .  So yeah your salad and juicing that you're doing for your health probably isn't doing much of anything in reality.  It is a small portion of your needs I suppose, but definitely no health boost.  For that get a cup or two of the juice of any of the 5 healthy ones listed.  Sweeten or dilute with other produce if you like, but don't count those ingredients as much of anything towards your needs.
