Two to one ratio magesium with calcium & Vit D3

by Andrea

I have read that when you take calcium and Vitamin D3, you should also take magnesium, in a two to one ratio re: magnesium and vitamin d for best absorption of calcium. I cannot find a formula that has all three of which magnesium is not made of calcium oxide. All magnesium tablets that I have found and in combination with calcium and Vit D3 have calcium oxide.

Hi Andrea,

So, these are interesting questions. Among which is the question of 'Do we really need supplemental calcium at all?'.

Well, the answer might surprise you:

1) Americans have the highest calcium intake and one of the highest osteoporosis rates in the world

2) Japan, China and Peru have MUCH MUCH lower intakes of calcium and much lower rates of osteoporosis.

So, while doctors are prescribing CALCIUM for bones, they really should be giving magnesium and vitamin d- which they almost never do until someone already has osteoporosis- and often not even then, preferring, instead, to risk the Osteoporosis Drugs that actually CAUSE more brittle bones, higher rates of Broken Femur and a condition called 'Osteonecrosis' where the jaw bone literally dies. Nice huh?

So, that is very debatable whether women need extra calcium at all in our western world where we have more calcium intake than most other countries already. And the more that I read, the more and more I lean towards no extra calcium at all.

Part of the reason for this is that most western countries have epidemic levels of:

Vitamin D Deficiency


Magnesium Deficiency

and both tend to go unrecognized for years and even decades, promoting osteoporosis. As you said, magnesium helps calcium to be absorbed- so does vitamin d.

So, since westerners already get more calcium than most other countries, I believe that if we actually optimize our:

Vitamin D Levels


Magnesium Levels

then we don't need any extra calcium at all.

And if you read my Magnesium Dosage page, you'll see that everyone has vastly different magnesium needs, so how can you say that everyone needs a set ratio?

While this maybe didn't answer your question, you would actually be better off optimizing your vitamin d and magnesium levels than worrying about any sort of optimal 'ratio'. And if you REALLY want to give your bones the best chance of staying strong, then make sure that you get weight bearing exercise and do resistance exercises regularly.
