I recently began taking this magnesium supplement, and I’m very impressed with its quality. The ingredient list is straightforward, providing a potent dose of pure magnesium. The size of the bottle is generous, offering a good amount of servings to support long-term use. The benefits I've experienced include improved joint and muscle health, as well as better sleep quality. This essential mineral has also positively impacted my hormone balance. The packaging was secure and ensured that the product arrived in excellent condition. Overall, this magnesium supplement has been a great addition to my wellness routine.

Heart Palpitations
22 May 2024

Apparently, the maximum recommended daily dose of magnesium for adults is 420 mg for males and 350 mg for females. The first time, I only took one capsule which gave my heart really strong palpitations at night and made my heart so anxious it was kind of scary. It also affected my bowel movement and resulted in diarrhea. I paused for a couple of days and took one capsule again and the same symptoms happened. I paused again for more than a week and went back to try and took half a capsule. The heart palpitations were less than usual but still there, but no diarrhea. I paused once more and then started taking around 30% of one capsule over 1 week and noticed that my sleep sort of got better and I could easily wake up earlier than usual. With that being said, I don't ... MoreApparently, the maximum recommended daily dose of magnesium for adults is 420 mg for males and 350 mg for females.

For years I have had problems with leg cramps & constipation. The cramps were because I was doing a low carb diet and I would wake up sometimes 3 times in the night with cramps in my calves, shins, and my toes would curve under so bad that I had to literally pull them straight. I have definitely seen results after a week of taking the supplements. I am sleeping at night finally the cramping has subsided in my muscles and joints. Hopefully they will stop altogether. As far as the constipation, my stomach was like steel nothing I took could help. I definitely have seen results within 3 days of taking supplement. I am so amazed at the benefits.

I'll start with the packaging. The box is dark blue, on which all the basic information is indicated. The box has a convenient lid that can be easily opened to remove the capsules. The capsules themselves are white and contain white powder. The capsules are easy to swallow despite their large size. Taking this magnesium, or rather magnesium, I felt changes in my body: I became calmer, more balanced, I began to feel more energetic, my nails became stronger, my joints stopped hurting before the rain.

For a short time, I think the succinate was missing from the caps. I should know, as I have been LE's Magnesium Caps for over a decade now. I stuck with the brand through that because of the ingredient quality and the testing of their products. My naturopath is also on board with this brand and dosage for me. All I know is that I eat, pretty, cleanly and still my body lets me know it is quite unhappy without magnesium supplementation. On it my sleep is better, my leg muscles do not wake me in the night with cramp (I also use magnesium chloride topically daily) and I am regular. I take this with my last meal of the day so closer to bedtime. I should say that magnesium is an essential mineral and is as necessary to supplement with as Vitamin D.

I would not trust food alone here with the things we do to the planet: soil depletion and farming practices and so on. I read magnesium is necessary for over 300 processes in the body. I know that it has different forms and uses. I would suggest you research it some and look at your diet/health needs. I started with Natural Calm (citrate powder) on a lesser amount before these caps to build my tolerance up to LE’s 500mg dosage. It never bothered me or made me anxious. (If this does that to you, I would suggest talking it over with your doctor and running some tests for other deficiencies. Like many other mineral needs in our bodies, everything has an adequate amount requirement of other ones to be effective).

This Magnesium is 5 Stars!
10 February 2023

I have had trouble getting a good nights rest for many years now. I was sadly beginning to accept the fact that I was becoming an insomniac. I would fall asleep as soon as my head hit the pillow, but would wake up within 3 -5 hours and be up the rest of the night. A friend recommended that I start taking magnesium. I didn't listen, I took everything else on the market that promoted sleeping - melatonin, tylenol pm, and many other sleep aids that only worked for a short time.I started a new medication recently, and one of the side effects is constipation. I was so uncomfortable and bloated. I would have done almost anything to gain relief. On top of that, I have been experiencing various injuries for working out.

I didn't listen, I took everything else on the market that promoted sleeping - melatonin, tylenol pm, and many other sleep aids that only worked for a short time.I started a new medication recently, and one of the side effects is constipation. I was so uncomfortable and bloated. I would have done almost anything to gain relief. On top of that, I have been experiencing various injuries for working out. To say I was not feeling my best self is an understatement.I started magnesium to help with my constipation, but it has helped me in so many other ways. I am sleeping through the night and not only sleeping, but getting that good, deep REM sleep that had been escaping me for years. I am also having very vivid dreams and actually remembering them more when I awake. I'm no longer constipated and I feel my muscles are repairing themselves much better and faster than before.I 100% recommend adding Magnesium to your supplement profile. It works wonders and the LIFE Extension brand is a great quality delivering 3 different types of magnesium in this supplement.It's been said Magnesium is one of the most important minerals in the body, and we need it for more than 300 biochemical reactions. I don't know what all it does in the body, but I am feeling much better since adding this mineral to my regimen.I will caution you to start slowly with only 1 per day as taking more may cause you to have diarrhea.

Tummy Upsets
14 September 2024

Bought 2 bottles to try. It did help with my sleep but I also had bad tummy upset when I started taking the first bottle. Cut the dosage and slowly increased to let my body adapt. Got better but still had upset tummy 2-3 times a week. Currently onto my second bottle and still the same reaction to this blend of magnesium. Not quite worth having disturbed sleep for diarrhea. I bought this for sleep, not as a laxative. Definitely won’t repurchase in future.Firthermore, there is no specification of the percentage of the different types of magnesium in the blend, both on the packaging or the manufacturer’s website.

The doctor prescribes and selects supplements for me. I've been drinking magnesium nonstop for 5 years now, and I've tried a lot of options. This supplement is definitely the MOST working one! Relieves headaches, helps to relax, improves sleep, very high quality of the product. When I have a headache, I drink several capsules, I like that this supplement does not cause a side effect with diarrhea. There are many good magnesium supplements here, this one is my favorite. Excellent quality and the most noticeable effects. Especially when a headache or stress starts. Drink magnesium to keep your heart and brain healthy.
