Magnesium citrate is better absorbed by the body than this presentation however this is why this brand is cheaper. You can find other magnesium supplements with a higher absorption rate but the price would be higher. I got these for my mom to help out balance out her sleep pattern and lower her stress but I can’t vouch for how well it has worked because it’s only been two weeks. My dad recommended magnesium to my mom because he saw great results.I just wanted to leave a review to remind people to buy the other kind of magnesium, the citrate kind which has better absorption. I didn’t do proper research so I’m going to finish this with my mom before I buy another brand.As with skincare please be mindful with supplement intake.

The magnesium supplement has truly impressed me. The quality and thoughtfully chosen ingredients make it stand out. Regardless of age, its benefits are noticeable. The size is convenient, and the packaging ensures product freshness. It has significantly improved my sleep quality, and the positive impact on mineral balance and hormone regulation is evident. Surprisingly easy to swallow, the taste is not an issue. The effects on muscle function, joint health, and overall magnesium levels are remarkable. A must-try for anyone seeking a high-quality magnesium supplement.

It's so hard to know with these supplements whether they actually work or not. I started to take these because I have recently taken up running and I was struggling with sore legs, mainly in my shins, and someone suggested that Magnesium helps with muscle repair. Desperate for something to help I ordered the Solgar tablets. They're decent sized round pills but what frustrates me is that the directions say to take three tablets daily. Three tablets is a lot, and I am sure that it is unnecessary, surely the ingredients that we need can be fitted into one or possibly two tablets. That's the only reason that I have knocked a star off as I do actually think that these work. About two weeks after I started to take them my legs improved dramatically, although they still ... MoreIt's so hard to know with these supplements whether they actually work or not.

About two weeks after I started to take them my legs improved dramatically, although they still get sore when I'm running which is frustrating, they don't hurt at all post run and I no longer have to wear compression socks after a run. I'm very happy about this and hope that soon my shins will be less sore during a run too!

Quality Magnesium supplement

You need magnesium for many tasks. It's involved in more than 300 chemical reactions in the body. Muscles need this mineral to contract; nerves need it to send and receive messages. It keeps your heart beating steadily and your immune system strong. You can get magnesium by eating foods such as green leafy vegetables, whole grains, beans, nuts, and fish. Even with an adequate diet, some people are at increased risk of magnesium deficiency, This supplement may help to benefit and support joint and muscle tension, low energy, and trouble sleeping

depression

I have fibromyalgia, depression and sleep apena with difficulty falling and staying asleep. I have found a and was told by a specialitst that you need to start with a small dose of magnesium once a day (ie: 250 mg) for a few days and then increase it to twice a day. Gradually increase the doses until you reach the peak of diarrhea; then back the dosing down until it subsides. Stay on that does awhile and if needed, try taking the dose up gradually again. I take a 1,000 mg twice a day and it helps with feeling less stressed as well. Also, for you chocolate cravers...magnesium is in chocolate and magnesium does help reduce and even eliminate cravings, which is different than having a urge to have some chocolate and being satisified.

My friend teases me and says why takes magnesium when you can eat chocolate???? My blood work has been perfectly fine and, as always, discuss this with your MD first. Not all MD's will support this idea or even understand it (I am a Registered Nurse). I don't mess with other products as I am on Paxil, which reduces the amount of Aleve I need for the fibromyalgia and, it helps the depression.
