Do you get enough magnesium in your daily diet? Foods rich in this essential mineral include seeds, nuts, whole grains, dark green leafy vegetables and some fish. Magnesium is a key player in basic cellular function in the heart and nervous system, as well as the catalyst for enzyme reactions that create energy. It supports a smooth, efficient pump in the heart muscle just as it also works synergistically with calcium to build bone. Our citrate formulation delivers over half the body's RDA of magnesium in one, highly bioavailable tablet!

Customer Ratings & Reviews

Rated 4.6 out of 5 by 109 reviewers.
Rated 5 out of 5 by For good health I understand this mineral is needed by the body in at least 300 functions. Swanson's minerals have worked for me these many years. October 20, 2016
Rated 5 out of 5 by Best Bang for your Buck There are many forms of magnesium on the market, (from magnesium oxide-least absorbed to magnesium threonate-best absorbed). This magnesium gives you the best bank for your buck. It is well absorbed but not obscenely expensive. For me the difference in price for anything else is just not worth it. The savings allow for me to add expensive to produce vitamins like K2 to my regimen. Love magnesium! October 3, 2016
Rated 3 out of 5 by Pill is HUGE! I have been taking these for a long time... hating it all the while. It's not that they are bad in and of themselves. But the tablets are SO huge I can barely get them down. They often get "stuck", and won't go down, then causes discomfort until I can get them "washed" or pushed down with food or beverage. I've tried breaking them in half, but they end up just scratching my throat, as the pills are very dry. I read a review where the lady tried chewing it! It worked for her, so I am going to try that. Otherwise, I will have to find another brand. April 30, 2016
Rated 4 out of 5 by Huge pill, but effective I seem to fall asleep faster when taking this supplement, however, as many others have said, it is a huge pill to swallow. I keep buying it, but it is a bear to get down. Don't know why they don't encapsulate this one. December 30, 2015
Rated 4 out of 5 by Good value This is a good product which I believe is more effective than magnesium oxide. The pills are huge and difficult to swallow, so I dissolve them in water. December 30, 2015
Rated 5 out of 5 by This is our standby This is the one, We've never bought any other magnesium since finding this one. It works, it's definitely absorbed, if you take too much, you'll know -so it's not hard to figure out your dose. We would never switch-been 7 or 8 yrs now.. Capsule is quite large, we find swallowing with a banana or food is best way, little issue then. December 29, 2015
Rated 5 out of 5 by One I can't do without Since it is estimated 80% of the people are deficient in Magnesium this is a great way to get a bioavailable form at a good price. December 28, 2015
Rated 5 out of 5 by gest value I was reluctant to purchase my supplements online until my doctor recommended Swanson. I was surprised at how fast my order was processed, and how quickly my package came. I've been talking my supplements now for several weeks and have nothing but good things to say. November 16, 2015
Rated 2 out of 5 by These are HUGE! These vitamins are HUGE, bigger than any vitamin that I have ever seen in my lifetime. Literally could barely swallow it whole. I did try one though, but it didn't seem to do anything for me. I used to take the liquid magnesium citrate which worked well (just tasted terrible), so I thought these would do the same. I tried one vitamin and it did nothing for me. Maybe it would take more than one vitamin to get the same results as the liquid, but I wouldn't want to swallow more than one of these at a time. October 27, 2015
Rated 2 out of 5 by loose stools It gives me very loose stools, even if I take with food. October 12, 2015
Rated 5 out of 5 by Easy to chew I like the high bioavailablity of this item, but what I haven't liked is how hard these rather large tablets are to swallow. These tablets only have a very thin coating which is not sufficient to ensure ease of swallowing. Then, I had an idea - try chewing them! Bingo! They are quite soft and have very little flavor. Problem solved! This is now my favorite magnesium supplement, especially when it's on sale. September 8, 2015
Rated 3 out of 5 by Very Hard To Swallow I take 2 tablets daily (AM-PM) and I find it helps me sleep sound and avoid night leg cramps. However swallowing this large pill is difficult and some times get stuck in my throat where I have to flush with Orange juice to get it fully down the "pipe". I have switched to a another brand with a slippery coating that aids swallowing with no gaging. This works for me July 21, 2015
Rated 5 out of 5 by Noticeable difference Taking magnesium has helped me in several ways. I felt a difference within one week. I did a lot of reading about my issues, and it sounded like the perfect fit for me. I was not disappointed, and plan to take this for the rest of my -much improved- life. As usual, the quality and value keep me ordering from anywhere else! My only negative comment would be that I have to break the large pills in half before I take them. May 12, 2015
Rated 3 out of 5 by would not buy again i bought these for the first time recently. they are very big pills, also they are not coated, therefore i have a difficult time trying to swallow them. i will have to return this product. i need pills that are coated- April 26, 2015
Rated 5 out of 5 by Good quality and value l was told to take magesium citrate supplements and these are excellent value.My only problem with them and l think it applies to all other magnesium supplements is that the tablets are so huge l have to cut them in half and then smooth down the sharp edges!l wish Swanson could make a smaller version! April 9, 2015
Rated 5 out of 5 by An Essential My husband and I are Senior Citizens and take this twice a day. We can really tell a difference it makes in many of our health issues. Knowing that our food is depleted of it's vitamins and minerals makes us more aware of the importance of supplementing. We also take a great Whole Food Multi-vitamin but find we still need the extra Magnesium. We're glad Swansons offers it at a price we can afford. November 17, 2014
Rated 1 out of 5 by Horse pills Not only are these pills impossible to swallow, but their magnesium effect is nil. I was so confident of Swanson products, I bought three giant bottles! gack. I'm throwing them out. I don't know anyone who could possibly swallow them, nor do I think they are effective. September 13, 2014
Rated 5 out of 5 by highly ingestible magnesium this is the best form of magnesium you can take and at swanson prices it's wonderful. some have complained of pill size but they are very chewable just like my wonderful l-carnitine tablets. with a little water after chewing they go down very nicely. May 26, 2014
Rated 4 out of 5 by Good Product But Large Pills I take quite a bit of magnesium on a daily basis. This product is a good value for the price. However, even though I am a good pill swallower I find these to be too large and a bit hard for me to swallow. I would much rather they were in capsules. May 8, 2014
Rated 5 out of 5 by Rebalance your minerals Dietary supplement for dietary balance. If the water you drink is low in Magnesium and you can't get enough from your food, Magnesium Citrate can easily be absorbed and balance your minerals. Excess Magnesium is no problem, while excess Calcium without Magnesium could be. April 8, 2014
Rated 5 out of 5 by TAKING A GOOD LOOK AT MAGNESIUM CITRATE Okay, let's take a good look at Swanson's Ultra Super-Strength Magnesium Citrate 225 mg. tablets. . . . . . . As one can read in Swanson's product descriptions, this Citrate form of the mineral is generally considered to offer the advantage of 'optimum absorption and maximum utilization.' Check. I find that to be true. I get my desired results with no downside. This tablet, while large, is not a 'horse-pill,' and is swallowable without any objections from me or my family. Furthermore, I have found that this Citrate form of Magnesium does not have a laxative effect on me as do the Magnesium Oxide capsules I have used. This Magnesium Citrate is reasonably priced, as are the other mineral Citrates: Iron, Potassium, and Zinc, which I also take and buy from Swanson Health Products, of course. For me that all adds up to an effective and desirable product for all the purposes for which I take Magnesium. I want the finest in natural nutrients for my heart, brain, skeletal muscles, and all areas of my body. I like this versatile Magnesium Citrate product very much. I recommended it to one of my daughters recently. She replaced the 'drug store / big box store brand' of Magnesium she had been using with this high quality, all natural Magnesium Citrate, and she also likes this one very much for all the reasons mentioned above. Very nice product. Works for me. March 10, 2014
Rated 5 out of 5 by Excellent Its big but just bite it a few times and then swallow. The taste is powdery and unoffensive. Remember - Anything that can be swallowed can be chewed. That is true and a nurse friend told me that. December 29, 2013
Rated 5 out of 5 by Super-Strength Magnesium Citrate Good product and very affordable!!!! December 12, 2013
Rated 1 out of 5 by Only order 1 bottle I purchased 5 bottles prior to trying and that was a mistake. They gave me major diarrhea. Be close to rest room if you try them. They may be a superior product but they sure weren't good for me. November 18, 2013
Rated 5 out of 5 by Simply a great product! As all Swanson products, this delivery exactly what it says! November 2, 2013
