Muscle twitches, magnesium and sweating

Answered on January 27, 2016
Created February 14, 2013 at 5:35 AM

Wondering if anyone can help with this.

A few months back I started suffering pretty intense Restless Leg Syndrome while trying to sleep. It took me a while to work out what was going on because I had never heard of RLS this before. I figured I was just restless until it got really intense and I realised something was actually wrong. I started doing a little research and I came across some articles that indicated that people who sweat a lot can end up pretty depleted in Sodium and Magnesium. I do Crossfit 4 to 5 times a week and sweat quite a lot. These articles said that being low in Sodium and Magnesium could contribute to restless leg syndrome. As a result I started adding electrolytes to my workout water and started taking Magnesium supplements. Just one tablet before bed. The restless leg has got better since but after a while I started getting muscle twitches and spasms. They seem to get worse the more Magnesium I take and they are all over the place. Legs, feet, arms, head, neck. Pretty constant too.

Now I???m really confused.

If I stop taking these supplements then the restless leg will come back.

However, I???m worried the constant muscle twitches are a sign that something is out of balance in my body. Could it be caused by excessive Magnesium?

Not really sure what my question is. I guess I???m looking for people who have:

a) Had restless leg b) Reacted to Magnesium supplements

If you???re in either of these camps, what did you do?

I wouldn???t have though I was taking excessing Magnesium??? 1 to 2 tablets a day. The muscle twitches definitely subside when I stay off it though.

Highly unlikely if there is no additional symptoms such as muscle weakness.

I never fully resolved this. I ended up increasing my carbs, stopped taking all supplements I was on and took a couple of weeks off training. Everything eventually went back to normal. I'm now thinking of increasing my magnesium through my diet rather than by supplementation.

Drink a glass of low sodium tomato juice a day, and it will go away. Most likely low potassium not low magnesium.

I have RLS, calve spasms/twitching, with weird twitching all over my body. No idea whats wrong with me....went to a doctor, did a mri and ekg, that was fine, then told me I had benign muscle fasculation. Which means I have muscle spasms....good job doc! No blood work, no mention of diet, vitamins/minerals. I think I'm deficient in minerals.

Calcium cound be the answer I'm looking for. I have a bit of cheese now and then but not regularly. I've just been relying on leafy greens for my calcium. I don't think potasium or iron would be the issue. I get heaps of both in my diet. It could be that I'm not absorbing them due to something like SIBO, however, I don't have any other idicators of SIBO and my diet naturally comes pretty close to a SIBO treatment protocol and I like my Kefir and Kombucha. Oh, and someone suggested eliminating salt... salt actually gives me a bit of relief from RLS. Makes sense as sodium is an electrolyte.

How's your Potassium intake?

My personal experience is that it's about mineral balance, so I take about 350 mg of Magnesium, (I eat low carb), bananas every so often for potassium, salt my food to taste and make sure I eat a variety of veggies, or sufficient liver to make sure I am getting enough of the other minerals.

Research and look into calcium supplementation, magnesium and calcium are antagonist.

I have muscle twitches too sometimes but think its related to SIBO and not absorbing some electrolytes properly, literally just had one as I typed this sentence.

Also, how long are you training for? You might be overtraining

Any update on the muscle twitching/cramping/spasms? I've begun to wonder if too much magnesium could be causing, or exaccerbating mine, as it definitely doesn't seem to be helping.

K, had similar problems and was going crazy with anxiety that it might be something much, much worse (like ALS).

But, when looking at the issue, it appeared that, overall, I was having several other symptoms related to electrolyte imbalance. Thus, magnesium for the twitching, potassium for the calf and foot cramping, sodium for some wooziness and zinc for night time sweats.

So, I think when one was up, it would throw others out of balance.

I started taking some Emergenc-C Heart Health brand stuff and nixed the whole host of weird, nagging issues I described.

I have the same reaction. After 3 weeks of taking magnesium, my muscles started to twitch all over the place. Dr. Carolyn Dean said that you can feel worst before better while the mg is absorbing into your system

Did you resolve this? I have a similar issue in that magnesium supplements cause me to get twitching in my lower legs but it has helped with so much else that I don't want to stop taking it. I am sure I burn through heaps of magnesium (for various reasons I won't go into). Interestingly I was able to tolerate high doses when I started taking it and now can only tolerate about 200-300mg per day. I often go over that for the other good effects then have to take calcium powder to make the twitches stop. At times I've also woken up with calf cramps from the magnesium (which is opposite to most people).

Note that I have food intolerances so that may play a part for me.

I'd be interested to see if you figured out the electrolyte balance issue, if that is indeed what it is.

May be worth getting a full iron panel done...

RLS may be associated with iron deficiency. A patient's iron stores may be deficient without significant anemia. Recent studies have shown that decreased iron stores (indicated by serum ferritin levels below 50 ng per mL [50 μg per L] can exacerbate RLS symptoms.11,12
Patients with newly diagnosed RLS or RLS patients with a recent exacerbation of symptoms should have their serum ferritin levels measured.
Source

& here's a case report,

This report describes a patient with iron deficiency in bone marrow examination and iron-responsive restless legs syndrome (RLS), in whom serum ferritin levels were well above the conventional cutoff for considering iron deficiency.
The predictive value of serum ferritin for iron deficiency in RLS depends on the cutoff employed, on the pre-test likelihood of iron deficiency and on coexisting inflammatory conditions. Bone marrow examination is helpful when ferritin levels are equivocal.

i also have RLS. i think it's from long term medication usage (prednisone, antibiotics). it is total torture. i even stopped one of my medications (6mp) because it was making it worse.

i rub magnesium oil on the bottoms my feet twice a day. once in the morning after i shower and then once before bed. it doesn't get rid of the problem totally, but it helps me get to sleep and to function better during the day.

Based on your level of exercise & sweating, electrolyte imbalance totally makes sense. As stated above by texas210, calcium & magnesium are antagonists.

Also be aware of vitamin k/k2 & vitamin D , along with sodium and potassium.

Had you not mentioned the huge volume of training and sweating, I might suggest considering food intolerance (histamine reactions or reactions to nightshades can cause such things in some people), but in your case, I would start with the more likely.

Have you tried reducing/eliminating salt from your diet? I had similar imbalances of calcium/magnesium that were directly related to the level of salt I consume. I no longer consume any salt, and don't have any cramps or need to supplement cal/mag anymore.

I just had someone tell me yesterday that he has to lay off the Magnesium for a week or 2 when it stops working (for muscle cramps) and then he can add it back in. May be a miserable week or 2 ...

Also, you may want to try other forms of Magnesium, like Magnesium Oil, Prill water, etc. Here is a good site for some very reasonably priced products (I love their gel, and use it in the shower):

I don't know much about magnesium.

However, as I was reading about SIBO, I came across Restless Leg Syndrome. There might be a connection to SIBO.

Sorry I cannot help more.
