I took this once every night for about 3 weeks to help me sleep—and it really helped. But then I noticed I was getting light-headed during the day, and also could feel my heart flip-flopping at night. I took my BP and found it was very low, with the top number sometimes dropping into the 80’s. And my heart rate, which usually stays around 60, had increased to the mid-80’s, and was very irregular. The only thing I had changed was adding the Mg supplement, so I checked the effects of excess Mg and found it does lower your BP, and can cause palpitations. I read that the max dose should not exceed around 320mg/day. The good news is that I stopped the Mg Glycinate completely, and within a couple days everything was back to normal, including a strong regular heartbeat at 60 per minute. Bottom line: just be aware of the effects of excess Mg, because it can be serious, and maybe start with 1/2 tablet.

I am no stranger to magnesium glycinate supplements in the context of knowing how well they are working inside my body. Poor quality supplements do not work well for me, whereas higher quality magnesium promotes good sleep and keeps my chronic hives away.<br /><br />However, the California Essentials brand works nicely at an affordable price. I would definitely purchase this brand of magnesium glycinate again as long as the price is right.

I heard that taking 400 mg of magnesium glycinate at night helps with sleep and feeling more refreshed in the morning, so I ordered this. I didn't have the highest hopes but it works! I had previously taken magnesium, but not the glycinate form. That did not do anything for me. But this product does!<br /><br />Pros:<br />I struggle some nights going to sleep because of restless leg syndrome, racing thoughts, etc. I take one of these about an hour before bed, drink a glass of water, and it really helps. Is it a placebo effect? Maybe, but I don't think so. I ordered it for my adult daughter, too, who lives away at college. She really struggles with insomnia and it's greatly helped her, too. She has even had a couple of prescriptions for sleeping meds. So far, she has been taking only the magnesium at night for about two weeks. I'm so thankful to have found something to help her sleep!<br /><br />Cons:<br />I really don't know of any at this point. Am I feeling more refreshed in the mornings? I don't think so, but falling asleep at night is the reason I ordered them and that's a win! The tablets are small enough that they're not hard to swallow. There's no aftertaste or anything. I am seriously impressed!

Lable on bottle recieved is totally different than lable shown in Amazon decription. lable in decription says Magnesium glycinate 400mg (From magnesium glycinate) 100% daily value, bottle recieved says Magnesium Glycinate 400mg yielding 56mg elemental magnesium 13% daily value. Bottle in decription says it is manufactured in LA CA, bottle recieved says manufactured and distributed by All Product distributer Inc, Rivervale NJ. Totally mislesding and wrong.

Magnesium is an alternative treatment for migraines, one your doctor probably won't tell you about. Do your research. It is working for me. I cut my migraine frequency to less than half, the pain is not nearly as severe, all in all less trips to the ER and much less RX pain meds and I have only been using the magnesium for about a month. It's worth the try for the low cost. I usually take two tablets with a meal. If I start to get a headache later in the day I will sometimes take an additional pill which is ok. I would highly recommend giving it a try. You might just get your life back.

"Impossible!" stated the ER doctor "Magnesium is the most abundant element in the universe!" An hour later he returned clutching an Rx prescription for magnesium oxide. "I just don't understand it" he muttered as he handed me the discharge paperwork.<br /><br />It's no joke that a shortage of magnesium causes episodes of atrial fibrillation in untold millions of people. And remedies like the drug Amiodarone are not merely hazardous, they are dangerous. I went from having AFib every Saturday to no episodes the last eleven years ... simply by taking Magnesium.<br /><br />But getting a lab test (like I did) would be more precise. Why am i now using Magnesium glycinate? I can take far fewer tablets than I did with Magnesium Oxide. If you know someone experiencing Atrial Fibrillation episodes, clue them in about this. They need to see their doctor about getting a test for their magnesium blood level.
