Extremely tired after taking magnesium

Hi.

A few weeks ago i started taking 4,400 ui vitamin d daily. Haven't felt any changes yet.

I read about vitamin d needing magnesium to work properly so 2 days ago i started taking 400mg magnesium citrate before bed (i read it's best to take it then as it helps sleep and i have occasional insomnia)

Since taking it i have been severely tired. I was tired before of course but the past 2 days have been ridiculous. It's been such a struggle to get out of bed and function.

Has anyone else experienced this? I'm scared to take it tonight because i have work tomorrow! I have slept like a log to be fair but i can't get out of bed.

Should i just drop it? Is it essential to take it with vitamin d?

I should add that i've started taking b12 and folic acid recently aswell but i've taken them in the morning and i don't think they would contribute to this severe fatigue anyway.

Thanks.

I was recommended to take magnesium a few weeks ago. It sent me spiralling downwards so fast it was scary. I tried it twice and the same thing happened. All my old symptoms came flooding back. I then read on a Facebook group that some people believe it can lower cortisol. That's certainly what it felt as if it did to me.

Have you had your adrenals tested with the saliva cortisol test?

Thanks for the info.

I have just had a blood test for celiac disease as i know that can cause low b12 and folate, so i'm waiting for those results and then if negative i think my next step is to do the saliva cortisol test as i have always suspected cushing's.

There are so many possible causes of symptoms it's very overwhelming. I came here at first because i suspected thyroid problems but since then i've discovered a ton of other possibilities it's almost like i've completely dismissed the thyroid as a problem!

I think i'm going to give the magnesium a miss tonight. It's great sleeping right through the night but come morning it's just not worth it.

Can vitamin d supplements still work effectively without magnesium?

He he, maybe you need to sleep more........ Sleep cycles last 90 minutes. Stages 1 to 3 plus REM. If you wake yourself up in the middle of a sleep cycle you will feel like doggy poop. So, sleep 6 hours, 7.5 hours or 9 hours. If you normally sleep 7.5 hours and then with the magnesium you go to 8 hours or 8.5 hours, you will be waking up in the middle of a sleep cycle and feel terrible.

As the night goes on, the amount of time you spend in stage 3 increases and as the morning comes on you will spend more time in REM (dreaming) sleep. You know what you are doing, so let's figure it out together.

I must admit, I take a whack of magnesium glycinate and citrate. I can't tell if it has had any effect on my sleep. I can't pay attention to this stuff. I have to get up in the morning to go to work. If I wake up at 5:30 a.m. (thank you Oscar Wild for jumping on my bladder) or if I wake up at 8 a.m. (because cats can tell what day of the week it is and since they know I don't work on Fridays, Oscar doesn't jump onto my full bladder) I have entirely different life experiences. And if god help me, I wake up at 4:30 a.m. because Deutsche Velle has some really obnoxious radio play screeching into my ears, I am uber dead. Yes, I know, turn the radio off at night. But radio set low is my usual white noise. Except when it's noise.

So I really can't ascribe taking magnesium to any other thing besides, um, nothing. (Magnesium citrate at least causes softer bowel movements.)

Hi calcium has to be in normal range. If taking D and it is too low you will not absorb the D ( NICE) , if calcium over range you must not take vit D regardless.

regarding magnesium. you may not need it. Ask for a blood test as must always be in range, an electrolyte.

Carpsy, checking in with you about your excessive tiredness after using your mag supplement. Same here. Suggested by my chiropractor that I take a mag supplement after a tissue analysis. I tried it for two days, but was terrified to take it again after experiencing a debilitating exhaustion upon consumption. I took 1 in the morning and barely made it through the work day, head literally dropping at desk. Next time at night, again, barely made it through the work day the next day. Have you learned anything else that helped you take a mag supplement w/out this side effect? Thanks!

If you have a magnesium deficiency taking a supplement can be too much to handle at first. You can start with low doses of epsom salt dissolved in water, about a 1/4tsp. Then work your way up from there. Once you get to a tsp you can try a supplement again. When I first started taking magnesium from Epsom salts, I almost felt high, a good indicator of deficiency. This will subside over time as the deficiency is corrected.

Hi I read 320g is what women should take but I too feel very tired on Magnesium.

It works really well to reduce chronic pain as I have Fibromyalgia.

Magnesium is very important for all parts of our body and yes having Vit D with it and Calcium is good.

Are you still feeling very tired?

Any update on sleepiness after magnesium? I have been taking mag glycinate for a week or two...240 mg and felt fine. Today I took a mag/calcium/d combo...375mg of mag and I am exhausted!! Maybe just a coincidence. I will see tomorrow in the coming days.
