Ok first off, I just want to say that I always pretty much only ever hear about calcium, vitamin D, and vitamin K in regards to "bone density" and very rarely of their many other functions, especially in regards to what magnesium can do when taken in the right balance/ratios with them. It's always about the calcium and the "bone density" and "directing it all to the bones", rather than any other functions. For instance, I'm primarily trying to raise my magnesium levels (blood calcium is ok, blood magnesium is EXTREMELY LOW), and as such I'm taking large doses of magnesium, mostly for glutathione production, but also for insomnia, anxiety, cramps, even digestion and headaches - all of which are alleviated by both magnesium and glutathione anyway. However, I'm certainly not taking this for "bone density". BUT, I have to take calcium, vitamin D, and vitamin K in order to make the magnesium do it's job (very very clearly the case, as all the symptoms comes rushing back if I take JUST magnesium). Which makes sense, because they both work together in the body, and one clearly doesn't work without the other... yet for whatever reason EVERY article I read states that calcium cannot work/absorb without magnesium, but not a single one of them mention that the opposite is true for magnesium also requiring calcium to do ANY of IT'S many jobs. Not sure why this, but I digress. Currently I have to take a much much larger amount of magnesium than calcium (2:1 and 1:1 ratios are out the window by a long shot), because of a severe ammonia/nitrogen imbalance where if I take normal levels of calcium (or rather just too much calcium for me), it makes me much worse overall and actually depletes my, already abysmally low, magnesium faster. So I take large doses of magnesium, and just enough calcium to "make the magnesium work", I also take reasonable amounts of vitamin D (also can't go too overboard on this) and vitamin K, but I'm wondering if maybe I should up my vitamin K dosage? I have before in the past, but not since realizing that I needed far more magnesium than calcium... and so I'm worried that too much vitamin K will throw my calcium levels up too high, but how can that be if it's a "delivers the calcium to the bones, system", right? And about the whole bone delivery system thing... how does that affect blood calcium levels? What if I don't want the calcium delivered to the bones to begin with, but rather to use the calcium to do it's many other jobs? lol. Feel like I'm going around in circles now. I guess my primary question is... can a very severe vitamin K deficiency lead to a magnesium deficiency, by extension of calcium deficiency? DO severe enough vitamin K deficiencies even lead to calcium deficiencies to begin with, or just a "calcification of arteries and tissues" - ie "calcium not being lead where it needs to go"? I'm not sure I even have a severe, or non-severe, deficiency of vitamin K (I definitely do for magnesium though), but I'm wondering if more of it would help bring my magnesium levels, without increasing my calcium levels too much? Sorry if this post sounds a little crazy, I'm just having a hard time understanding exactly what it is that vitamin k does especially, but also all of calcium and D and mag and their relations, since practically all you ever hear about them is BONES.
