Review: If you take these, titrate up to the 3 pills daily just to be safe. Your butt will thank you. - Update: Changed review from 2 star to 5 STARS! I have continued taking these when life got a little busy and I noticed the side effects were no longer a problem. It obviously was caused by my having switched Magnesium types, even though there was some time in-between. I figured since I paid the money and it helps with bowel movements, just finish the supply and then try a different type. Well, after a while I noticed I was feeling better. So I kept it up. Several months down the line and also adopting regular epsom baths and magnesium in spray form, it has literally changed my life. Originally i started taking this to help with alleviating the painful and frustrating symptoms of fibromyalgia and to help with bowel issues. After two decades of this hanging over my head, the muscle issues are gone and no longer dealing with the debilitating brain fog/chronic fatigue. I still have food intolerances every now and then, but my body is Here's the real kicker. My menstrual cycles have NEVER been regular. I average every 3-6 months and sometimes it's twice a year. After several months of being on this, my menstrual cycles have returned and for the first time in my life, I have a more or less regular cycle. It seems like I'm still "adjusting", that is, my hormones are less of an issue, my sex drive is increasing gradually and it doesn't feel like metal on metal with the headaches when I put the foot to the pedal. I'm sure now I had some form of a severe deficiency. Doctors could pick this up on test and the spray is a very quick way to get it into your muscles. I recommend in addition to taking this, that you also get the Life Flo spray. I knew my life was changed when I found a huge bottle of muscle relaxers in the car that I forgot I'd even filled. I hadn't touched the stuff in months. That said, I would still heed the warning in my previous review, if you are on another supplement, to be sure you "ease" into these. They gave me violent diarrhea and very bad reaction. I know when I read as being linked to my condition, I was skeptical. All I can say is give it a try. The magnesium spray does help and it also will help with anxiety if you're dealing with those symptoms as well. Though, you have to take it for many months and expect you'll be taking it for longer after that to get back to peak condition. I guess if you're like me and have seen every specialist under the sun and been given any real answers about this "disease", then you really have nothing to lose. But again, ease into this supplements... they took more than a month for me to change. For whatever reason, I reacted very poorly when first taking and I think because I'd been on other less-absorbent magnesium for far too long. Old review: I'm sorry that these pills made me poop a lot. I usually take magnesium citrate so I can poop better. The directions on the bottle that say take 3 pills daily made me poop way too much and also made me feel like death. I was taking 2 doses of Spring Valley Magnesium @ 400mg ea most days and occasionally 1 pill a day to manage chronic constipation. I made sure to stop it 4-5 days before I started these so I could be relatively objective on their effectiveness. Seeing as many people can tolerate the 3 pill dose, I started on it right away thinking these must be mild. I soon felt the effects of what felt like my body was being poisoned and felt like I was going to die. I did some googling and it is indeed possible to overdose on magnesium. I fell under the category of what would be considered mild overdose of it is what I experienced. I'm in wonder as to how most others don't seem to have had this issue. I experienced nausea, dizziness, severe abdominal cramps, violent diarrhea, breathlessness and as I was going back and forth to the bathroom constantly and was utterly confused about what I was experiencing. Having been diagnosed with interstitial cystitis/painful bladder syndrome and also probably having un-diagnosed IBS (I have generally high pain and trouble when I poop) this was extra painful as it was like the hell's wrath was released on my entire pelvic region. I almost felt like going to the ER then and there but my $300 copay said no and so I waited until it washed out of my system. Against what some would perceive as common sense, I stopped for 24 hours and then started again on two pills. I had some milder diarrhea which aggravated my bladder further and caused some more pain but thankfully only lasted until I couldn't go to the bathroom anymore. After a few days, I went back on for 1 pill. I felt mild cramping that felt like I was on my period. Did not last very long so I wasn't concerned. I take in the recommended amount of water daily but still suffer chronic constipation so it really should not be because of water. I figured it was low magnesium. I started taking magnesium a few years back because of a kidney stone and had high calcium levels come back on blood tests, so I figured I did not have enough magnesium to keep calcium in check. The Spring Valley Magnesium citrate you can buy at Walmart worked fine for me though I felt like maybe I was losing some of the other benefits such as reduction in pain as well losing some water as it did seem to flush my system quite a bit. I looked for a higher quality magnesium supplement so I bought this because of the reviews. I don't necessarily recommend people not to try these. Obviously this has worked wonders for some, but my body has some issue with these and I recommend to most people just starting them to start on 1 pill and not 3. Some people have written they are taking 6.... I don't know in God's name some people are able to do that. I'm 100% certain I would've been in the ER if I even attempted to take more than the 3. It was just a little scary.
Review: Awesome supplement! - I was taking magnesium malate from double wood supplements until I started noticing my fibromyalgia was really bothering me with muscle cramping and pretty decent aches in my whole body. I also had noticed the last few bottles from double wood supplements were very powdery and almost all capsules were missing powder?! I switched to these tablets to ensure I would be getting a consistent amount in each pill. I literally feel like night and day (almost). I’m not even sure there was much magnesium in the double wood supplements!! My mind is literally blown! I WOULD NEVER TAKE ANY SUPPLEMENTS FROM DOUBLE WOOD SUPPLEMENTS!! I’m so unbelievably happy I switched! My quality of life is considerably improved.

## Questions & Answers

**Q: Can anyone tell me the size of the tablet and it it is difficult to swallow?**
A: I think these tablets are too large to swallow. I take a lot of supplements, but I have a limit on the size of the pill that I can swallow. With these tablets, I crush them. Because they have a bitter or chalky taste, I make sure I have some chocolate to to with them to make taking this pill more palatable.

**Q: Why does the label say 1250 mg and the pill are 1/3 of that dose?**
A: 1250 mg would seem to be the mass of each tablet. Only about 15% of the mass of magnesium malate is the magnesium, which is the nutrient you should be concerned about. The rest is the malate, which carries the magnesium and helps your body absorb it. You want to calculate your dosage on the mass of magnesium, not the mass of the whole tablet. To get 425 mg per 3 tablets means each table is 11.33% magnesium. That is a little less than the 15% mentioned above, so the difference would be the other ingredients that bind the tablet together and perhaps coat it.

**Q: Specifically how many mg of magnesium in each tablet**
A: According to the listing on LifeEssentials.com, 3 tablets contain 3.75g of Magnesium Malate Trihydrate.  Since this is a compound, it then details 425 mg (142mg/tablet) of Magnesium and 2.5 g (833mg per tablet) of Malic Acid.  This is great for people who specifically are needing the benefits of Malic Acid, as this is one of the highest amount I've seen so far per tablet.

**Q: can you break this pill to make it easy to swallow?**
A: My bottle has capsules, so you can't cut it. But fairly easy to swallow anyway.

### ⭐⭐⭐⭐⭐ Magnesium - miracle supplement for me
*by Y***U on February 10, 2016*

I discovered Magnesium Malate through an online forum for heart problems. About 2 months ago I woke up with a pounding heart beat and BP through the roof. I thought I was dying. I practiced deep breathing and my heart rate eventually went down. I finally went to the doctor. The news was not good, weight too high and BP too high. I don't want to be on diabetic meds so we agreed I'm going to maintain a lower calorie diet, less sugar and more wholesome foods. Being overweight, high BP and chronic pain from a frozen shoulder that had ran it's course for 2 years was grinding me down to the dirt. I still don't have complete ROM with my shoulder but the pain (which was on the scale of a 9) had dissipated. But the damage to my adrenals, my heart and my muscular skeletal system was still there. I wanted to workout to lose excess weight but I was too darn sore and tired to do so. I started getting panic attacks in public. On one occasion I started sweating and getting the shakes. I had no idea what was going on. I thought maybe I'm hypoglycemic and borderline diabetic but this is just crazy. I had my husband grab some deli meat from the store and a glass of tea. I ate the meat and tea and started to feel better. But these attacks were happening at least two times a week. I thought this is ridiculous, I cannot live this way. So I started taking snacks with me to town. So I decided to try magnesium malate. Within 3 days I felt a difference. (now to be fair I did start using Wellesse liquid glucosamine along with it, so maybe that helps a lot too). My heart palpitations stopped. Panic attacks gone. Sleeping throughout the night. My BP is almost back down to normal and my joint pain is down from a 9 to about a 2. I can live with that for now. I'm giving myself a few days to get my strength back and I'm going to start working out again. I don't want to be one of those seniors who's always complaining about their aches and pains and their doctor being the person they see the most besides their family. I did exhaustive research online about my symptoms and educating myself about WHY I was feeling this way. It's amazing how the little things can completely change the game. I was taking baking soda three times a day with water for GERT. Each tsp has about 1250 milligrams of sodium. I didn't realize it. The GERT was from eating lousy foods, stress and other factors. I stopped the baking soda. Eliminating the lousy foods got rid of the GERT. I cut out most caffeine. I only drink 1 cup of coffee a day, one soda for lunch and the rest of the day water. Once I figured out what I was doing wrong, simply by eliminating the offending items, I'm back on track again. I'm not there yet, and I have a long way to go. This is what I'm doing. 1. Drink plenty of fresh water daily. 2. Eat plenty of fruits and vegetables. 3. Eliminate most sugar, desserts, fast food and processed foods (which are really high in salt). 4. Take my magnesium three times a day. I set the alarm on my phone to remind me to take my vitamins or I'd forget. 5. Exercise daily. Just do something. I have a timer on my computer. When 20 minutes has passed I get up and do something. Wash a few dishes, comb my hair, clean around the house, something. 6. Take my Wellesse Glucosamine daily. This is how I know the magnesium is working. Yesterday I took 3 pills at once. (Big mistake because they don't absorb that well taking them all at once. I needed a continual flow of magnesium to help me). By the time I came home from town my knee hurt and I could feel my heart doing the pitter patter. Woke up twice last night from slight heart palps. So taking the right way from now on, spacing the pills out (which I feel is extremely important in this supplement) and I'm back on track again. I apologize for the long rant, but if I can help one person who's experiencing what I'm experiencing (I'm a female in my mid 50's BTW) then my review will be not be in vain.
