- Why you need to go with a supplement with the right calcium, magnesium,
zinc, copper ratio such as Body Wise
Magnesium--A Forgotten Mineral - Health & Nutrition Breakthroughs, 9/97
"Excess calcium and phosphate also interfere with
magnesium absorption. (Thus, taking calcium supplements without adding
magnesium could result in magnesium deficiency.)"
Inhibitory effects of zinc on magnesium balance and magnesium absorption in
magnesium absorption in man - J Am Coll Nutr. 1994 Oct;13(5):479-84 -
"the overall effect of the high Zn intake of the three groups combined,
regardless of the Ca intake, was a highly significant decrease of Mg
absorption and of the Mg balance"
Zinc -- The Immune System's Missing Link? - Health & Nutrition
Breakthroughs, 12/97 -
"Supplementing with zinc is quite safe--its only
significant side effect is lowered copper levels in the body tissues, since
the two minerals compete for absorption. Considering zinc's safety, people
should consider taking zinc supplements, especially as they age--being sure
to include copper in the proper balance. Most practitioners who supplement
their patients' diets with zinc also recommend taking copper at a ratio of
10 mg to 15 mg zinc for each milligram of copper."
Calcium, Keep What You Take - Life Extension Magazine, 3/99 -
"The final study was a two-year, placebo controlled
trial on 225 postmenopausal women. One group received calcium supplements
only, the second group zinc, manganese and copper, the third group received
calcium plus zinc, manganese and copper, while the fourth group received a
placebo. After two years, the only group who experienced an improvement in
bone mineral density was the group taking calcium plus zinc, manganese and
copper" - [Abstract]
Magnesium: The Multi-Purpose Mineral - Think Muscle Newsletter -
"If you take high amounts of calcium daily, you may
have a magnesium deficiency. Most experts suggest that your calcium:
magnesium ration should be 2:1. In other words, if you take 1500 mg of
calcium daily through diet and supplementation, you should try to consume at
least 750 mg of magnesium daily as well"
Magnesium, the invisible deficiency that hurts health - CNN.com, 12/31/14 -
"Magnesium is involved in over 300 biochemical reactions
in your body. It affects everything from your heartbeat to your muscles to your
hormones ... only about 25% of U.S. adults are at or above the recommended daily
amount of 310 to 320 milligrams for women and 400 to 420 for men ... at least
half of the U.S. population had inadequate intakes of magnesium ... a magnesium
deficiency may eventually cause noticeable problems with your muscle and nerve
function such as tingling, cramping, numbness and contractions (like that
annoying eye twitch you just can't shake). In its worst stages, magnesium
deficiency could even cause seizures, personality changes, or abnormal heart
rhythms ... Since only 1% of magnesium is found in your blood (most is in your
bones or organs), a simple needle prick often won't help determine your levels"

Calcium Intake and CVD
Risks in Older Patients With T2DM - Medscape, 10/20/14 -
"Our data indicated that 60.9% and 87.3% of our patients
were Ca and Mg intakes below RDA, respectively. Patients whose Ca intake was
high or low (81.2%) had significantly higher C-reactive protein (CRP) than those
whose Ca intake was moderate (p = 0.043). Furthermore, patients whose Mg intake
was low (87.3%) had significantly higher CRP than that of those who took
adequate Mg (p = 0.025). The dietary Ca:Mg intake ratios were highly correlated
with CRP, platelet counts, and red blood cell distribution (p < 0.05). A dietary
Ca:Mg intake ratio of 2.0–2.5 was significantly correlated to lower CRP levels
(p = 0.013)"

Magnesium levels vital to brain health as population ages - Science Daily,
11/4/13 - "the human brain begins shrinking after age
25. Structural changes and loss of brain synapses lead to rapid decline in
cognitive health ... magnesium deficiency in adults may play a more important
role in CI, and more seriously, Alzheimer's Disease (AD), than previously
thought ... elevation of brain magnesium through dietary intake of magnesium
threonate exerts substantial positive effects on brain synapes in a mouse model
of AD, actually restoring aging brains to their youthful conditions ... the
'gold standard' of science, demonstrates that dietary supplementation of
Magtein, patented magnesium threonate, can significantly enhance human cognitive
functions and decrease symptoms of cognitive impairments ... We know that as we
age our bodies naturally lose magnesium. For example, drinking coffee or
caffeinated products increases the loss"
magnesium research and its role in reversing effects of Alzheimer’s - Nutra
USA free download, 9/24/13 - "Magtein is the only
magnesium compound that has been shown to effectively raise the brain’s
magnesium levels, which leads to enhanced learning abilities, working memory,
and short- and long-term memory in both young and aged animals. In four
published preclinical studies, Magtein was found to improve memory, alleviate
anxiety and help prevent the decline and reverse the symptoms of Alzheimer’s ...
Here, we show that increasing brain magnesium using a newly developed magnesium
compound (magnesium-L-threonate, Magtein) leads to the enhancement of learning
abilities, working memory, and short- and long-term memory in rats"
Elevation of brain magnesium prevents and reverses cognitive deficits
and synaptic loss in Alzheimer's disease mouse model - J Neurosci.
2013 May 8;33(19):8423-41 - "Here, we
investigated whether elevation of brain magnesium by the use of a
recently developed compound, magnesium-l-threonate (MgT), can ameliorate
the AD-like pathologies and cognitive deficits in the APPswe/PS1dE9
mice, a transgenic (Tg) mouse model of AD. MgT treatment reduced Aβ
plaque and prevented synapse loss and memory decline in the Tg mice.
Strikingly, MgT treatment was effective even when given to the mice at
the end stage of their AD-like pathological progression ... Our results
suggest that elevation of brain magnesium exerts substantial
synaptoprotective effects in a mouse model of AD and may have
therapeutic potential for treating AD in humans"

children to have healthy bones. One of these appears to be magnesium ...
Results showed that the amounts of magnesium consumed and absorbed were key
predictors of how much bone children had. Dietary calcium intake, however,
was not significantly associated with total bone mineral content or density"
CKD and Low
Magnesium: Pay Attention - Medscape, 2/6/13 -
"When adjusted for differences in age and sex among quartiles, the lowest
magnesium group had the highest incidence of new atrial fibrillation events
(9.4 episodes per 1000 person-years). The rates for the other 3 quartiles
were quite similar (6.9, 7.1, and 6.3 events per 1000 person-years for the
second, third, and fourth quartiles, respectively). In multivariable models
controlled for the multiple potential differences including glomerular
filtration rate, those with the lowest levels of magnesium continued to be
at highest risk for the development of atrial fibrillation (hazard ratio,
1.48; 95% confidence interval, 1.02- 2.14; P = .04)"
Induced by Proton Pump Inhibition - Medscape, 8/29/12 -
"PPI-induced hypomagnesaemia (PPIH) ... Proper
identification and treatment of PPIH therefore mainly rests on three
pillars: First, serum magnesium monitoring on a regular basis. In event of
existing hypomagnesaemia discontinuation of PPIs should result in a rapid
normalisation, which may be supported by additional magnesium and calcium
supplementation. This step is crucial to exclude other causes of
hypomagnesaemia. Second, regular determination of serum magnesium (and
concomitant other electrolytes) should be done to monitor the course of
recovery. This should be accompanied by urinary magnesium measurements to
assure renal magnesium retention. Third, patients with PPIH have the chance
to escape hypomagnesaemia by alternative acid suppressants. Therefore,
switching to H2RA should be attempted. In cases of insufficient relief
from acid related complains under H2RA, tapered or intermittent regimes
including PPIs might be helpful. Also here, urinary magnesium monitoring is
of benefit as it declines prior to the serum magnesium as an early
indication. In most cases reviewed here, supplementation with
electrolytes could be stopped after normal serum magnesium was obtained"
Magnesium lowers blood pressure, study suggests - Science Daily, 3/13/12
- "In the trials, the magnesium supplementation
doses ranged from 120 to 973 mg with between 3 to 24 weeks of follow-up.
Although not all individual trials showed significance in blood pressure
reduction, by combining the trials, the overall data indicated that
magnesium supplementation reduced both systolic and diastolic blood
pressure. With the best results observed at the higher dosages"

- Medscape, 8/2/11 - "In conclusion, findings from this
prospective cohort study of women suggest that potassium and magnesium intakes
are inversely associated with risk of cerebral infarction among women with
hypertension. We observed no protective effect of calcium intake on stroke risk"
Citrate key in bone's nanostructure - Science Daily, 6/8/11 -
"At this point, we feel that citrate probably also has a
role in the biomineralization of the apatite ... It's also been noted in the
literature that as an organism ages, the nanocrystal thickness increases and the
citrate concentration goes down ... "and there's also support from clinical
studies that citrate is good for bones," adding that one of the leading
supplements for bone strength contains calcium citrate ... While calcium loss is
a major symptom in osteoporosis, the decline of citrate concentration may also
contribute to bone brittleness" - Note: I read a long time ago that the
citrate form of most minerals was absorbed better and have been using that form
for some time. For example, see the magnesium citrate in
magnesium supplements at Amazon.com.
