Magnesium Glycinate vs Mag L-Theornate for sleep disorder?

Im someone with lupus with no relapse from 5+ years. Living healthy active life. Ive been having this sleepless nights situation for more than 6 months. I workout 4x a week does 10k steps daily and I calorie count all my meals. After having gone through intense workout sessions i just couldnt fall asleep. I tried mag glycinate 2caps of 240mg it makes me more alert my brain races with thoughts. Even if i fall sleep i wake up to the slightest of noise and cant go back to sleep again. Then I doom scroll on my phone, after few hours my body jus gives up if im lucky i get may be an hour sleep. im just surviving on 1-3 hrs sleep per night. Note I finish my workouts by 6 pm and i usually go to bed by 11pm. This is my schedule for years. From last 3 days i started Mag L-theornate 2000mg in magtein form 144 elemental mag. Bottle suggests to take 2 caps at night and 1 during day but with that dose im feeling fatigued groggy. So jus doing 2 caps at night. I say its working better i can sleep from 11pm to 6am. Much better than where i was before. Is this grogginess common? Few say its adjustment phase and should get over in couple weeks. The more i research the more articles pop up that mag gylcinate is more studied and safe than mag l- theornate. As someone with lupus i want to take these supplements with caution. Atp im stuck in a loop, without 7-8 hr sleep im worried about lupus relapse and other health issues. Mag glyecinate looks safe but that has opposite effects on me. L-Theornate works but i feel fatigued and not sure if its widely used for sleep issues.

Irrational fears/intrusive thoughts from magnesium deficiency?

For background info I used to have depression and anxiety that were caused by my prior heart problems. After fixing iron deficiency and back then mild magnesium deficiency - I had ZERO anxiety and depression for almost two years. I then started to supplement vitamin D first 2000IU then switched to 4000IU. I didn't realize that my magnesium was dropping despite supplementing it, meanwhile my calcium and phosphate both shot up to borderline high levels. I started to have bad health problems after 4 weeks that started with nerve burning, later body shaking and then irrational fears (that I never had before). Found out that I also had iron deficiency again, copper deficiency and zinc toxicity. My magnesium is so badly depleted that I can't even go two days without taking it or I get severe symptoms. Went to neurologist and two MRIs were both clear but I had all signs of nerves being hyperexcitable. I managed to fix zinc toxicity, working on fixing both copper and iron deficiency but my magnesium is even worse because I restarted another vitamin D supplements month after that. Only stopped recently. The irrational fears are nothing that I've ever experienced. My old anxiety in the past was completely rational and connected fully to my heart problems. I was wondering if someone had any experience with this. I read about Amygdala and how magnesium is very important for it.

Hair Mineral Testing

​"Hello, I need help analyzing my Hair Tissue Mineral Analysis (HTMA) results. Over the past few months, I’ve experienced vision issues, muscle weakness, and abnormal muscle function.

​A notable point: I took 400 mg of magnesium daily from April 2025 to March 2026. After stopping it in March, I noticed significant changes in my muscle function. The test was conducted 3 weeks ago.

​Please note that I am Korean, so my translation might sound a bit unnatural. Thank you for your understanding!"

Magnesium making me feel anxious?

I was taking a different brand of magnesium glycinate, and I thought it made me less anxious after taking it everyday for a month. I changed the brand recently, and I feel surges of adrenaline/panicky feeling almost out of nowhere along w/ tight sternum which is also bc of anxiety. Has anyone experienced this?

Possible depletion of magnesium due to high dose vitamin D supplementation

As the title states, I believe I may be deficient in magnesium or at least insufficient now due to high does vitamin d supplementation which started in May.

I was diagnosed with vitamin D deficiency on May 10th (27 NmoL) and I was prescribed 7 weekly doses of 40,000 IU to take once a week - I finished around June 20th, then I went to Mexico from June 22nd until July 3rd.

I fell ill towards the end of the holiday and ended up with diarrhoea for two weeks, which is also known to deplete magnesium - the last 10 days I’ve experienced loads of symptoms that overlap with potassium and magnesium.

I also had a b-12 injection on July 8th and that’s when symptoms seemed to ramp up.

PPI & Esomeprazol HELP

Hello everyone. This seems to be the group I’ve been looking for because I need some elaboration. I’ve been on Esomeprazol for 2 years due to acid reflux. I get a lot of pain in my esophagus if I stop the PPI. I’ve tried to stop it, I tried to tapper it down without success.
Now I think I got magnesium deficiency. I did a blood test and it came back as : P- magnesium 0,71 mmol/l
Reference is:0,70-95
So I’m at the low end. I got no symptoms that I’ve thought of…a bit of leg cramps if I get cold, but I’ve always had that.
Calcium and everything else is normal.
I started magnesium glycinate today. I take 2 capsules which mean I get about 375 mg of magnesium.
My doctor says I’m fine and to supplement.
I think I need to be on the PPI, or be in pain. I have been on 20 mg x 2 each day of Esomeprazol, I’ve managed to get it down to 1 pill every other day - it sure gives me more pain but - I’m trying.
Will this help me to get my levels up or am I wasting time taking the supplements because PPI blocks everything?
What would you do in my situation?
I’m thankful for any help….

magnesium glycinate calmed me down more than I expected, does splitting doses actually make a difference?

Been taking magnesium glycinate for about three months now, started for sleep issues which it genuinely helped with. What I didn't expect was how much calmer I feel during highpressure days. Not sedated, more like the edge is just... less sharp. Deadlines hit the same, but the physical response feels different. Less jaw clenching, less of that tight chest feeling that used to creep in around 3pm.

Curious if others have noticed this or if I'm just connecting dots that aren't there. I've read a bit about magnesium and cortisol but I'm not trying to go deep into the science here, just want to know if the stress angle is something people actually experience or if the sleep improvement is doing most of the work indirectly.

Also wondering about dose. Currently at 400mg before bed. Some people seem to split doses throughout the day and swear the timing matters a lot. Has splitting it made a noticeable difference for anyone, specifically around stress response versus sleep? The sleep benefit feels locked in for me, I'm just not sure if I'm leaving something on the table by frontloading it all at night.

Possibly low on magnesium?

Around two months ago, I went to urgent care because I felt unusually weak and dizzy with leg cramps and constipation. I felt so weak at work once I was afraid I'd pass out. The doctor examined me, and ran numerous tests. Turns out my blood pressure was a little high despite the fact I've never had blood pressure issues. My resting heart rate was also slightly elevated. They ran tests on my heart as well, and they conclude my heart is healthy. I was told to drink more water to help with the constipation. Before I left that day, they took bloodwork.

   Now prior to this, I have had toe spasms in my feet every 2-3 days or so. They normally only lasted about five minutes each, but could vary. They were uncomfortable, but I just walked them off until they subsided. Occasional twitching in my arm. This has been going on for the past six months. Up to the UC appointment, I took no daily medications or supplements at all. I would take OTC Tylenol during the first few days of my period, or when my muscle aches were at their extremities, but that was it.

   A few days later, I get a call with my bloodwork results. Everything they checked was normal except Vitamin D, which was 25 ng/ml. She didn't say this was a severe deficiency, but it was considered an insufficient level and should be at least 30 to be considered in the normal range. She tells me to take 5000 iu D3 daily, which I begin to do so the next day. I was never told to take Magnesium.

   Two weeks later I visit my GP for my scheduled routine check-up. By this time I'm having mild acid reflux and still feeling weak so I mention this to GP. She examines me, says I'm in great shape, but anxiety is my issue. Apparently anxiety and acid reflux go hand-in-hand. I had nothing to be anxious about, it's nothing I dealt with daily until this weak feeling set in. She prescribed me 20 mg Prilosec to take daily each morning, and told me to keep taking the D3 daily.

Fast forward a couple more weeks and I'm feeling even worse. I had a heart palpitation in the middle of the night and an anxiety attack stemming from that, I usually don't sleep well at night anyway but I stayed up for the rest of the night with restless legs and the feeling I was going to faint. I decide to check the paperwork for my Prilosec prescription and happen to notice PPI medications can cause low magnesium levels in the body. (Usually only after several months or over a year of taking them) so I didn't think my PPI would have caused that that soon.

However, on the paperwork for the Prilosec, it listed symptoms of low magnesium. I had every single one listed. Was it that I just had low magnesium all along? I decide to do a little research on D3 and apparently you shouldn't take it without magnesium because your body needs an adequate supply of Magnesium to utilize the D3. I even learned taking D3 can deplete magnesium stores even further, especially higher doses like I was taking.

I was already feeling weak and I was afraid I'd make it worse, so I cut down to 1000 iu D3 daily and started taking Magnesium glycinate 200 mg a couple hours before going to bed. The first few days I made sure to up my potassium a bit by eating a couple bananas a day so my body could adjust easier. I am still taking my prescribed Prilosec.

Fast forward a few weeks to the present, some of my issues are gone, but not all of them. For one I sleep better at night, and I'm no longer feeling near as anxious. I am no longer constipated. However I'm still having the muscle cramps, especially in my shoulders, back, and ankles. The feet spasms are still prevalent. I don't feel near as weak as I did but the feeling comes and goes. I have good days and bad days, but the days seem better than they used to two months ago.

I go see GP again in a couple weeks for a scheduled appointment. I will definitely discuss magnesium with her and see if she can get my levels tested. I am not sure if my insurance will cover it, but I'm very curious. I'm not even sure if low Magnesium is my issue, but at least I sleep a little more soundly now.

Are these actually low enough to cause symptoms

So I just got out of the ER for some pretty rough symptoms and they treated me for low potassium and low magnesium they also said it’s likely I have POTS. I guess I was just wondering if these levels being low could actually cause bad symptoms?

Magnesium glycinate symptoms?

I had the flu in Dec and it caused severe sleep disruption and post viral dysautonomia and POTS. Started taking 200 magnesium glycinate and also metoprolol which seemed to give me a little sleep. Went from 3am wake ups or not being able to sleep at all. As time goes on it seems like the sleep I am getting is deep. I used to hear noises and wake up. Now I feel like my cat walks all over me and I don’t notice. I wake up feeling groggy and not refreshed no matter how long I sleep and I feel weirdly sad in the morning. Does magnesium glycinate cause any symptoms?

I really need help

I already made a post a few days ago. Thanks to everyone for the information. I already applied everything people suggested, but right now I'm at a point where I feel like I'm dying.

For the people who didn't read my previous post, I'll explain it briefly. Two years ago (I'm a 22M), I started having severe insomnia and a lot of crazy symptoms. I wasn't a functional human being at all, but I tried my best anyway. One year later, I had a blood test and found out I was vitamin D deficient, so I thought, "This is it!" I started taking 5,000 IU of vitamin D a day along with 400 mg of magnesium bisglycinate daily.

After about a month, I started feeling really bad, like I was actually dying (severe shortness of breath, as if I had asthma, strong palpitations, and severe insomnia again). I quit vitamin D forever and kept taking magnesium at 200 mg a day because I felt like it helped. Later, I increased it to 300 mg.

I had another blood test in which my vitamin D went from 18.18 to 62. My calcium was 10.4, and my serum magnesium was 1.7, right at the lower limit. Copper was deficient too. Since then, I've had severe palpitations every day, my insomnia came back, I became extremely sensitive to any sound that triggers an adrenaline spike, I have constant fatigue, spasms in my arms, muscle twitching, and endless anxiety. I feel like my nervous system is electrified.

I feel like I'm going to die soon. This is too much. The palpitations, the muscle twitching, the spasms... I can't sleep unless I take clonazepam, and even then it only helps me rest peacefully without the crazy adrenaline surges or spikes but the sleep doesn't feel good anyways, is just a patch. It's like whenever I fall asleep, my body starts going crazy, my heart, my brain..

Doctors DO NOT help.

Everyone tells me that everything is within range and that they don't treat copper deficiency because it's only 2 points below the lower limit of 70 and they are not familiarized with it.

They tell me I need to fix my sleep (as if I could) and that I just have anxiety. I honestly feel like I'm going insane. I can't get any help. I can't get a cellular magnesium test because it doesn't seem to exist in my city, and it's impossible to get it through the public healthcare system because it's "too expensive." Man i would pay it if it existed in my country

Even my family treats me like I'm a crazy person, like anxiety is the only problem. I feel so isolated.

I've been taking 400 mg of magnesium for the last 3 months, and it doesn't seem to help at all, or at least that's what I thought. Usually, whenever I stop taking it (just to test it), I start feeling even worse and worse, so I keep taking it.

I really can't understand how doctors can be this incompetent. I'm not sure what to do anymore. I feel like I'm going to stay like this forever unless a doctor actually helps me and guides me, but there isn't a single doctor in my city, not even privately, whose answer isn't just, "Everything is within range."

I feel so miserable.

Anyone has gone throught this?

Too much magnesium and CBD oil

Hi all.

Iv taken magnesium glycinate, citrate and malate with CBD oil before bed and been having these heart pounding sensations for the past 2 months.

Had ECG's, blood tests, stool tests and everythings came back normal.

The doctors want to prescribe me with anti anxiety medication but don't want to go down that road.

Was wondering if anybody could help me with this situation I'm in and hit me with some knowledge.

Anyone here taking **magnesium** or **zinc**?

Anyone here taking magnesium or zinc?

What benefits have you actually noticed after taking them? Better sleep, recovery, energy, less stress, anything?

Also:

  • Which type do you take?
  • What's your daily dose?
  • How long did it take before you noticed any difference?

Right now I only take:

  • Creatine (5g daily)
  • Whey protein
  • Vitamin B12
  • Vitamin D3

My main goal now is to improve my sleep quality as much as possible.

Are there any other supplements you guys take that have actually made a noticeable difference? Just looking for real experiences, not advertisements.

Thanks!

High Potency Magnesium

Has anyone tried this brand of magnesium? Is it optimal to be paired with 1000IU D3 to boost my Vitamin D?

What foods do you incorporate?

..... For magnesium?

I've recently been using nut powders ie peanut butter powder. I use 70g every night. I just make it into a peanut butter texture and mix it into some yoghurt.

Looking online it looks like this has around 250mg+ of magnesium. Adding this to your original diet should give a decent boost to magnesium intake.

I can't take any magnesium supplements. They all make me feel terrible. Food magnesium seems perfectly fine though.

What foods do you all incorporate? Also why is magnesium such a hard mineral to get from diet alone? It seems like everybody who doesn't supplement is deficienct. Makes no sense.

Magnesium glycinate grogginess

Does the grogginess from magnesium glycinate go away? I took 600 mgs the last 2 days and my insomnia is gone but the daytime grogginess is a concern. Could it just be my body catching up on needed rest or should I look into other forms? Thanks in advance.
