Does magnesium deficiency cause insulin resistance?

Answered on August 19, 2014
Created August 22, 2011 at 1:00 PM

If I understand Dr. K's blog post below, that is what he is asserting:

http://jackkruse.com/gnolls-com-opens-the-door-to-obesity-fight/

It seems plausible, and of course as a T2, I'm very interested...

Any papers that support this? (Wow, Dr K. - you have your own tag!)

Well, you don't have the best reputation among the blogs I tend to frequent. Kudos to you for being a voice in the wilderness who is finally getting some respect. Nobody owns the truth in this nutrition/metabolism mess and it's going to be a while before all of this gets sorted out.

One of free's studies above was in diabetes prone rats. Mg supplementation forestalled diabetes in all but one of the rats while controls all became diabetic. Yet Mg supplementation of already diabetic rats did not improve their situation. For me the lesson is supplement with Mg. I've yet to see where it can hurt, it's cheap so it's not going to break the bank, and it seems to do a world of good.

I missed your comments here Dave. I'm going to take a look at that paper if I can get the full text. I'm working on a general cause/effect post that includes Mg, VitD and BCAA's as examples. It's something I add to from time to time and hopefully I'll have something to publish to the blog soon. I'll try to remember to come back and link to it here for any interested. My gut feeling and initial lit research has me leaning strongly towards the deficiencies/excesses being an effect rather than the cause of the conditions they are associated with. Strangely honored ? Hmmmm :-)

Hey CarbSane, this may not be the smoking gun, but I'd say it's pretty warm: http://www.springerlink.com/content/mjdtugth6fbdw2le/ "This study reveals a strong relationship between decreased serum magnesium and MS. [non-diabetic Metabolic Syndrome]. So, (1) Mg deficiency can cause IR. (2) Strong correlation of MetSyndrome and Mg deficiency. Maybe it always precedes it? (It certainly precedes it in many or most cases - I'm open to the possibility that a T2 might have enough Mg. But wouldn't the IR worsen intracellular Mg status? So maybe it's a moot point.

I guess that is the crux of my question. Is magnesium THE cause of IR. One of many colluding causal factors (including, say fructose, alcohol). Or even simply a result of IR, making it worse. I'm guessing that it is causal, but not alone. (As usual, the body is not simple). And I'm strangely honored by the presence of CarbSane!

There must be exceptions, but my assumption is that the vast majority of it occurs as a result of hyperuricemia from heavy fructose intake coupled with ascorbate deficiency and a sedentary life (that doesn't restore muscle insulin sensitivity).

I asked if Guyton & Hall qualified. I don't have the time to follow links through abstracts and texts when I'm looking for specifics. Of course anyone could do a Google scholar search an Mg and IR and find a shitload of citations for a correlation. One citation backing up that assertion is all I'm looking for.

Plenty of them. Thousands in fact. Carb sane asked for one in the comment section and I pulled one off my hard drive. Any biochemistry book or endocrine book has them listed as well. Very commonly written about but it appears not the tip of many people tongues who talk about IR.

Here's a few relevant studies:

  • Mg in diabetic rats: better glucose control and less diabetes development.
  • Low Mg diets in healthy humans for 4 weeks: 25% reduced insulin sensitivity.
  • Mg in diabetics: increased insulin sensitivity. Specifically,
  • Mg over 16 weeks in diabetics: 22% HbA1c improvement.
  • Mg in insulin resistant people for 4 months: 43% reduced insulin resistance, 32% reduced fasting insulin, 39% reduced triglycerides.

Just out:

Nine studies uncovered a significant protective effect for increased magnesium intake against the risk of diabetes. A 22 percent lower risk of diabetes was found for those whose intake was highest compared to those whose consumption of the mineral was lowest. Each 100 milligram per day increase in magnesium was associated with a 14 percent lower risk of developing the disease.

Further analysis revealed a more pronounced effect for the mineral among those whose body mass index was more than 25 kg/m2. "It is plausible that high magnesium intake may have greater effects on improving insulin sensitivity in overweight individuals who are prone to insulin resistance,"

However, she is so full of conventional wisdom and so wrong, IMO, in key areas (no saturated fat, whole grains, etc.), that it makes it difficult for me to follow her advice on magnesium. She also says that magnesium needs to be taken on an empty stomach. I cannot find any other source that says this. What about the timing of taking magnesium supplement?
