Talk:Magnesium deficiency

message: In the chapter titled "Incidence/prevalence" it is stated:
"A less than recommended dietary intake does not necessarily imply magnesium deficiency in an individual"
There is no citation to back this up and it does not make logical sense either as the RDA was set up specifically to help prevent deficiencies.
I request permission to remove this sentence.--197.79.0.1 (talk) 19:14, 31 May 2013 (UTC)

message: Very nice job on the rewriting and fleshing out, Nescio. However, I think one thing might have got confused in the rewriting: 
: "Magnesium depletion" (ICD10 code E83.4) should be distinguished from hypomagnesemia
The original version read: 
: It {Magnesium deficiency} should be distinguished from hypomagnesemia or "magnesium depletion" (ICD10 code E83.4).
I think that "Magnesium depletion" is more similar in meaning to "hypomagnesemia" than to "Magnesium deficiency" (or at least that's the implication of the article in the external link). Maybe I'm wrong. But in any case, I think the article should make it clearer what "Magnesium depletion" refers to. --Arcadian 21:37, 29 October 2005 (UTC)
replies: text: Hypomagnesemia only refers to bloodlevels. This is not the same as lack of magnesium for whatever reason (see hypomagnesemia). Deficiency and depletion in my opinion merely diferentiates between intake and loss. --Nomen Nescio 01:27, 31 October 2005 (UTC)

message: "Magnesium sulfate (Epsom salts) has been recommended as a magnesium source, but the sulfate content makes it more laxative than other soluble magnesium sources, so it must sometimes be limited in dose, due to this side effect."
This seems to imply that magnesium sulphate acts as a laxative because of the sulphate.  If this were true than Magnesium Hydroxide (a notable laxative) would not be a laxative.  If there is a citation that says specifically that in the case of epsom salts the laxative effect is due largely to the sulphate, then it could be put back in.Fireemblem555 (talk) 06:30, 31 October 2009 (UTC)
replies: text: I think it is saying that magnesium sulphate produces a laxative effect at a lower dose than magnesium hydroxide. That would seem slightly counter-intuitive since a sulphate group has double the mass of a hydroxide group, but maybe the sulphate dissociates much easier than hydroxide? Still, this needs a reference. --Mark PEA (talk) 18:39, 31 October 2009 (UTC)
replies: text: It needs a reference, but is correct. Sulfate is not very well-absorbed, so acts as a laxitive on its own, for a double effect. Sodium sulfate is laxative. Other soluble magnesium salts have anions which are well-absorbed, so the magnesium ion is the predominant active laxitive in them. They can be compared to the relevent calcium or salts, which are actually consipating. SBHarris 00:00, 27 February 2010 (UTC)

message: Magnesium's beneficial effects in inhibiting neurogenic release of inflammatory cytokines may help explain why magnesium deficiency is recognized to correlate with migraine and MCS by sufferers and treating physicians. 
Weglicki WB, Phillips TM.
Pathobiology of magnesium deficiency: a cytokine/neurogenic inflammation hypothesis.
Am J Physiol. 1992 Sep;263(3 Pt 2):R734-7. Department of Medicine, George Washington University Medical Center, Washington, DC 20037.
During the progression of Mg deficiency in a rodent model, we have observed dramatic increases in serum levels of inflammatory cytokines [interleukin-1 (IL-1), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-alpha)] after 3 wk on a Mg-deficient diet. Sequential analyses of these cytokine changes in the serum of rats revealed an initial rise at day 12, followed by a major elevation in all three cytokine levels by day 21. Of greater interest was an early peak in the serum level of the neuropeptide substance P after only 5 days on the diet. This "neuronal" tachykinin is thought to be released from neural tissues, and it is known to stimulate production of certain cytokines, including IL-1, IL-6, and TNF-alpha. In addition, there was a concomitant increase in histamine levels, which may have resulted from stimulation and degranulation of mast cells by substance P. Thus we hypothesize that the release of substance P may be the earliest pathophysiological event leading to stimulation of the inflammatory cytokines, which may then stimulate the free radical mechanisms of injury previously confirmed by our work.  —Preceding unsigned comment added by Ocdcntx (talk • contribs) 19:01, 28 February 2010 (UTC)

message: The makers of DermaMag claim people absorb magnesium from their proprietary skin lotion far more effectively than they absorb oral magnesium. Does skin absorb any magnesium? If so, how effectively? What forms are how absorbable? Verdant C (talk) 01:56, 1 December 2010 (UTC)
replies: text: It's probably a bogus claim. I can find no backup for it (the solution in DermaMag is magnesium chloride). There is an experiment which seems to show magnesium absorption through the skin in humans by bathing in concentrated Epsom salt solution (magnesium sulfate) but it's not well done. In general, the evidence that much magnesium ion gets through the skin, is poor. In general, ions don't get through your skin well. If they did, soaking a day in seawater would certainly be fatal. SBHarris 07:30, 1 December 2010 (UTC)
replies: text:  Sea water does not contain much magnesium and makes the last point moot. However Dead Sea water is a different story and relatively contains a lot of magnesium chloride. See WP articles on same. 99.251.114.120 (talk) 03:08, 28 March 2012 (UTC)

text: You can be pretty sure, but you're wrong. Morphine and nicotine for such uses (lipid solubility) are uncharged alkaloids (they are always freebased for skin-use, so they ARE uncharged. When dissolved in water, morphine must be acidified so that it is charged). Uncharged freebased alkaloids get through skin okay, if put in lipid. There is no such thing as "magnesium chloride oil" for the two do not go together (think of oil and vinegar, except worse). Magnesium chloride dissolves in water, but cannot be dissolved willy-nilly in any type of lipid, for it must ionize on dissolving and it cannot ionize in lipids or hydrophobic liquids. Any company that claims it can get magnesium ion through your skin is pulling your leg. Do you not understand the idea of "nutritional scam artist"?  Has the concept not so far crossed your awareness? Or perhaps you are participating in some multilevel marketing scam and so you WANT to believe this nonsense.  For the record, magnesium absorption from supplements is actually better than food, provided the supplements are of the soluble type, and not the oxide or hydroxide that rely on stomach acid to solubilize.

message: I'm proposing this merge because I think that these two articles would be better covered together, rather than separately. This is because:
* Causes, symptoms, pathophysiology, diagnosis and treatment are all the same
The only difference is that one is low levels in the acute setting and the other is low levels in a chronic setting. It would be better to cover these in the same article under a classification heading. If these are to be merged, I think that this article would be a more accurate title than hypomagnesemia, as it is technically true that a person chronically deficient in magnesium could have, in the acute setting, normal magnesium levels. Would value comments. LT90001 (talk) 07:55, 29 August 2013 (UTC)
replies: text: A merge could work, though there would be a risk of confusing the terminology 'hypomagnesaemia' and 'magnesium deficiency'. The specific definitions of each would need to be clearly communicated. Arripay (talk) 21:36, 22 October 2013 (UTC)
replies: text: In the meantime, hypomagnesia should not redirect to hypomagnesemia but to magnesium deficiency (medicine), here. I will correct this so that hypomagnesia and hypomagnesemia won't be confused. Eklir (talk) 02:20, 7 October 2014 (UTC)

thread_title:  Proposed merge with [[Hypomagnesemia]] 

message: This article seems like an appropriate place to list the detailed RDA advice from various authorities in various countries.
It is a peculiar situation that most US and other modern westerners (at least) ingest much less Magnesium than recommended. Which raises an obvious serious issue of whether most of the population is actually at risk or suffering -- or if the level is set too high. Please add more details about the history of the RDA level-setting processes for dietary Magn, with appropriate sources.
In this case, it would be particularly apt to also include Estimated Average Requirements (EAR) numbers. The Dietary Reference Intake article currently says:
* Nutrient  EAR  RDA/AI  UL  Unit
: Magnesium 330 400 350(ii) mg 
: (ii) The UL for magnesium represents extra intake from dietary supplements. High doses of magnesium from dietary supplements or medications often result in diarrhea that can be accompanied by nausea and abdominal cramping.[12] There is no evidence of adverse effects from the consumption of naturally occurring magnesium in foods.
