The title of the article caught my eye and so I thought I'd pass it on (not because I thought it was THE CURE, but it may help some. In fact a calcium-magnesium supplement makes a HUGE difference to me. This is a case history - a woman tired all the time yet unable to sleep and suffering brain fog, brittle nails, and muscle aches. She was diagnosed with depression, anxiety, and sluggish thyroid, but Synthroid did not help her. She went to a naturopath to get a complete workup and was diagnosed with a calcium deficiency. She was told calcium is needed by the thyroid and the adrenal gland (I did not know this - never read this, will check into this). She had read in the news that calcium is dangerous and had stopped taking it. The naturopath told her it is safe when a "natural form" is taken with trace minerals. (I think this 'natural form' is bogus unless it means that NATURALLY one takes calcium WITH TRACE MINERALS. In fact, it has been proven that w/o Vitamin K you cannot absorb calcium into your bones and it simply clogs your arteries. Also zinc and copper are important trace minerals for using calcium as proven here: http://journals.cambridge.org/action/displayAbstract?fromPage=online&aid=5154620). So she started taking a whole foods calcium supplement with magnesium, D, and K, and eating more calcium-rich foods like spinach, chard, and Greek yogurt. In 3 days she was sleeping like a log, feeling energetic, and whole. (My additional comments: I believe it is the magnesium that allowed her to sleep. If she would have taken a cal-mag 1:1 supplement (such as citrate, NOT carbonate or oxide, which are scarcely absorbable) at 1.5 times the daily dose spread out over the day she could have slept like a log in one day (it works for me unless I am over-caffeinated late in the day). Also chipping nails is a symptom of inadequate copper, not calcium, and if her trace minerals included copper then that is what fixed them. Trace minerals magnesium, zinc, copper, and manganese, as well as D and K are very important to absorbing and properly utilizing calcium). ----------------- But even more important than her problem and cure, case study only of course, is that she got a nutrient workup and proceeded to correct a deficiency. Someone else's deficiency may be different. You can get a mineral workup from a hair analysis such as www.evenbetternow.com ($100) wich sends to the lab www.tracelements.com (w/o having to pay for a doctor visit). You can get D levels checked at your doc or www.lef.org or www.directlabs.com. You can surmise your K levels if any form of osteopenia or arthersclerotic plaque has been detected in you. In Michigan, Beaumont hospital is running a 7 test for $70 which includes EKG and ultra sound of major arteries. (ok, maybe you can detect K levels by blood test but I never needed to as I was provided other feedback which said - not enough. There are always health fairs willing to do a bone density check).
