Hello,
I have just started taking magnesium as a supplement ( apro. 150 mg/day ).

Aproximately 1-2 hrs after taking I feel very jittery in my muscles and restless in general. It does not make a difference if I take it with calcuim. I understand magnesium is natures relaxant but it seems to have the opposite effect on me. Has anyone had this problem or know what may be causing this ? Sarah.

EC: Hi Sarah, can you tell us the exact ingredients in your supplement? Thanks!

Hello, my comment is regarding Sarah's posting (from North Vancouver, B.C Canada). I have a similar reaction to magnesium. Lately, I have been taking Bentonite clay (which is rich in magnesium) and it has kept me up and energized, the problem is that if I take it close to my bedtime, I simply cannot get any sleep. The dose that I am taking is quite large (2 tablespoons) and not only I do not experience any calming effects, it does not have any laxative effects either. I have read some postings here on EC regarding the relaxing effects of magnesium but for some strange reason, the opposite happens to me. I had attempted to address the problem by not having any caffeine after lunch time and also sticking to a light early dinner thinking that those were the reasons for my insomnia, and not until recently when I was purchasing clay from a website and read someone's comment about magnesium keeping them up that I made the connection. I remember having the same problem when taking magnesium citrate. I would appreciate any comments. Thanks!

May I ask why you are taking extra magnesium. I started taking it since I seem to have candida and I also have a mitral valve prolapse. After taking it for a few a month I started gettting major muscle twitching. I even got a heart cramping feeling every now and then. Perhaps you don't need extra magnesium. Perhaps you are throwing your calcium balance off. Even if you take calcium with it it might not be properly absorbed. Certain types of calcium are absorbed better than others. What magnesium were you taking? Was it magnesium taurate, or another form. Perhaps there is a underlying cause for you symptoms that are not related to the magnesium.

I've been having similar reactions to magnesium. I took it as a natural muscle relaxer because I'm tired of taking Rx for my back. I started taking 600mg of magnesium oxide in 250mg tablets (I broke them up to make 3 servings to reach 600mg) Within hours the muscles started to relax (I was shocked that it worked so fast) by the fourth day I started having pain in between my shoulder blades, shoulders, neck, jaw, headache, and in my armpit. This was followed with my heart pumping so hard that it felt as if my heart was in my throat. Needless to say I stopped taking it for about a week and a half and the muscle pain came back with a vengence. I thought I'd try taking 250mg a day by breaking the pill in half and taking 1/2 two times a day. It took the edge off my pain, but not as good as with 600mg. Unfourtunately the chest/heart pain came back with in a few days and I stopped taking it again. nearly four days of being off it and my pulse is still to high to donate plasma. I don't want to take calcium with my history of kidney stones, and I had issues with potassium supplements about nine years ago when it was reccomended for a low carb diet I was on. My heart was racing so fast I thought I would faint and fall to the floor. does anyone have any suggestions on how to make my heart/ chest pain stop and/or a safer alternative to relax the muscles without scary side effects. by the way the added ingredients in the mag supp I was taking is: cellulose, starch, croscarmellose, vegetable magnesium sterate. The brand is from a popular pharmacy chain. Any advice would be greatly appreciated.

Hi Colleen,

If that pharmacy chain starts with "R", then I would say your reaction to that supplement doesn't surprise me. I've purchased different things from them that smelled like some weird strong glue when opened, way before any expiration date (of course I returned them!). Things I had taken from them that didn't smell like that never seemed to do much anyway. I don't buy their suppplements anymore. It's worth paying more for better quality.

I would suspect the additives in the supplement as causing your problems before suspecting the magnesium itself. How about some food sources to get that extra magnesium? A food source is always better than a supplement if the food source is of good quality. Eating the whole food means you get all the synergistic compounds it may contain as opposed to an isolated nutrient. Pumpkin seeds have very high levels of magnesium as well as lots of other nutrients. I buy an organic dry roasted brand that are low sodium. A handful a day can give you quite a nutritional boost. See this link for lots of good info on pumpkin seeds:

Beans and spinach are also very good sources of magnesium, as are chinook salmon and halibut. If you feel you still need some supplemental magnesium, perhaps you might want to try the magnesium oil foot soak as described here on EC. Bear in mind that magnesium, calcium, and potassium do need to be balanced; this is very important!

Good luck, and please update us!

I've been taking both Magnesium Gluconate tablets for some time now, and have just started to soak my feet in Epsom Salts (Magnesium Sulphate).

By far the best way to take and absorb Magnesium into your body is either by soaking yourself in the bath for at least 20 mins (adding 3 cups of Epsom salts to the bath water) or to use a little warm water (enough just to submerge the soles of your feet and toes in a small bow), add and dissolve 3 tblsps of Epsom Salts, and soak your feet for half an hour (less wasteful than a bath, but just as good). The reason that this is the best way to absorb magnesium is that its absorbtion does not require the digestive system, so there is no chance of problems like diarrhea. Also, by soaking, the body will only absorb the amount of magnesium that it needs, so this method works well with your body's magnesium regulation.

The first time that I did this foot soak with Epsom Salts was at 9:00 pm at night. By 10 pm, I was so relaxed and tired that I just went to bed (I usually never go to bed before 12 at night) and I woke up the next morning wide awake and fresh for the day. No brain fog or grogginess.

I'm 60 y o and I do this Epsom Salt foot soak once a week now, or whenever I have aches and pains(which rarely happens now).

I also use an 8 oz garden spray -- which contains water 3 teaspoons Epsom Salts 1 teaspoon of Borax(20 Mule Team brand) to spray onto the outside of my body after showering and drying. I rub it in and leave this to dry naturally on my body.

These soaking and spraying methods are far more efficient and safe than supplementing with magnesium pills. They also deliver far larger amounts of magnesium into the body than oral supplements, and it is completely safe with no side-effects.

What is the borax for? Does this spray leave your skin chalky? Sounds like a great idea. I just tried epsom and water 1/2 & 1/2 and it turned me all white where I sprayed it.

Hi Colleen...You use a much higher concentration of epsom salt in your spray than I do. I just use one heaped tablespoon in water in a small 8 oz spray container. This does not dry white on the skin. Using a 50-50 solution will not do you any harm, but it will settle as a white powder on your body due to being a much heavier concentration.

Forgot to add that I add the borax to kill off any fungus, bacteria etc on my skin. You don't have to add it to the spray mixture if you prefer.
