Has anyone had experience with Magnesium L-Threonate specifically? I just ordered some with a calcium additive.

I have not seen anyone posting here yet using magnesium L-threonate. It will be interesting to see what you discover.

I ran across this paper today, and since the question often comes up ..as to how much magnesium and/or sulfate is absorbed from a bath containing epsom salts, I thought to link to this paper here:

http://www.epsomsaltcouncil.org/arti...um_sulfate.pdf

I'll be sure to report back on the results. I've been on a quest for the past year to find the "perfect" combination of supplements to help brain recovery. This forum has helped a lot!

This is a very interesting article for those here with elevated glucose and neuropathy...

Thanks to bent98 for finding it and sending it to me.

Hi Mrs D hope your vacation was a good one and has left you feeling refreshed. I am found my way to this site in my quest to research Magnesium, its nutritional qualities and effects for my own health and well being and also at same time for our Horses benefit.

I do not have a medical reason for posting here and do acknowledge the huge support this forum gives to people in need of nutritional help and advice in response to their illness or difficulties. I am though very committed to researching as feel there is a lot of misconception and misinformation freely available. I have to admit I am very confused after reading lots of varying thoughts etc on the internet. I want to make the right choice but I am also aware when people want to 'sell' a product they can often use language which is not always clear!

I have read a lot of your information in this thread going back over several years and wanted to know if the studies and benefits of taking Magnesium Oxide still stand today?

Also do you have any information/understanding of Calcined Magnesium Oxide (Reactive Light Burn MgO) I understand there are three ways to 'burn' magnesium and is graded high-grade deadburned (DBM), electrofused (EFM) and calcined (CCM) I now know CCM is graded from KS85 KS90 KS92 KS94 and KS95. With 85 being the lowest Magnesium and is also the cheapest form.

I have also comes across Magox which people say is a heavier form of powder. I have recently discovered Magnesium Chloride which is extensively used in the agricultural industry where it can be given to lactating cattle at 250gms per day and I also see we humans can benefit from baths containing this form.

My main reason for trying to understand the mag ox V mag chlorine debate is because of our horses. On horse forums mag ox is widely used and mag chlorine shunned because it is used for Cows! Now when researching Mag ox it is also used by Cows and Fertilisers for arable land. I have yet to find a study which supports mag Ox while at same time have found good reports about mag chl.

Can you offer me your thoughts please, this would help also with a course I am starting called NRC plus with a DR Kellon from USA over the internet which hopefully will give me a broad perspective on nutrition.

All the best

There is a paper done on humans, where several types of magnesium were given...and blood then drawn and measured to see if magnesium levels changed (went up) after the dosing.

I don't know if cows with their 4 stomachs change the oxide type or not for absorption. But in humans the oxide is not appreciably absorbed. It moves on to the colon where it osmotically draws water into the lumen and improved stool passage. (laxative).

A typical MagOx for humans is 40% by weight magnesium. But it does not dissociate into free ionic form. So it is basically not useful for improving blood levels. It remains on the market and in doctor's therapeutic manuals, because no one has taken the effort to look at the newer information.

I am having good results using it in lotion form. I apply it to my wrists and legs where veins are near the surface of the skin.
It really helps me sleep quickly after applying at night.

This is a new study about magOx and bioavailability:
http://www.ncbi.nlm.nih.gov/pubmed/20862466
Ionized magnesium is preferred. There is a product called
Ionic Fizz which creates the ionic form from magnesium carbonate.

more:
http://www.ncbi.nlm.nih.gov/pubmed/1468087

So basically the organic chelates offer better oral absorption.
Chloride is also well absorbed according to some studies.
But any EXCESS in dosing of even these forms will be excreted and become laxative. There is a transport system in the bowel to move magnesium, and it can become saturated. One study suggests several small doses rather than one large one for this reason.

update, need opinions!!





a little background. i need some magnesium experts!!!!!!!!

last summer i was dx'd with a magnesium deficiency. serum mg was .5 (1.5-2.2 range). i have a RSI and extremely tight muscles, winged shoulders, which i am in physical therapy for and parasthesias in both my hands constantly for 2 years now.. muscles not spasming but the muscles are insanely tight even tho i avoid using them. i have gotten massage blah blah blah, they just tighten back up even when im not doing anything. i am in a strengthening program

started supplementing a ton with citrate and glycinate and epsom on occasions. in november my rbc magnesuim was a 4.7 (4.2-6.8 range)

last week i tested..like 10 months later and it's just a 5 (4.2-6.8). my serum mg when i have tested it..is always like a 2.

ive been taking 800 mgs a day. i am going to start taking at least 1000-1200 each day. the thing is i do FEEL the magnesium. sometimes i feel almost too relaxed when i take high doses. i dont like it

so with rbc magnesium testing, do your red blood cells change out like every 3 months or is my rbc magnesium slowly increasing over time and adding to my mg stores (make sense?) should i expect my rbc magnesium to go up .3 or so in the next year? or this unusual and my magnesium should be higher for taking so much?

thanks all. ive posted this elsewhere but haven't really gotten any replies.

It is difficult to say.

1) you might be losing it from the kidneys quickly. If you have undiagnosed kidney problems this may be a factor

2) you may be saturating the transport mechanism by taking
large doses all at once, instead of spacing the total daily dose out into smaller doses.

3) you may be using a drug that depletes magnesium

4) Diuretics including alcohol and caffeine will deplete magnesium.

5) diabetics lose magnesium naturally thru the kidneys...the reason for this is not well understood.

I wouldn't object to further clarification on doses, if possible. I haven't taken doses as high as mspennyloafer's because I wasn't sure if it was safe.

Here's my situation in brief:

I thought I was at a good dose with 300 mg citrate (and the 600 mg "Oxide and Glycinate" in my multiple), but it has been a rough summer. After reading another thread, I tried to up my benfotiamine from 300 mg to 600 mg, but that seemed to make things worse (might have been the heat). Last night, with bad pain in my hands and feet, I seriously thought of taking neurontin for the first time.

I know that it is hard to state a dosage that applies to everyone, but can you give me a parameter of safety?

Thanks!

P.S. I hadn't thought of spacing out my daily 300 mg dose. Maybe I'll try that.
