Best Magnesium Supplements Reviewed & Rated for Quality


Magnesium deficiency has a special term: hypomagnesemia.  While deficiency in this mineral, which is abundant in the body is uncommon, less than 2% of Americans are affected, it can still manifest for some.  Studies show that up to 75% of people are not actually getting their approved intake. Many times this issue goes undiagnosed because the most visible signs of a deficiency don’t come to be visible until the amounts in your system are severely low.  As with any deficiency, the reasons why can vary widely. Poor diet-rich sources plus the body’s own loss could be the culprit of such shortcomings.

Now a bit about the mineral itself.  It is abundant in the body as previously stated and it is part of many of the foods that we eat. It can also be found in supplementation. It is also found in over the counter drugs like antacids and laxatives.  It is helpful in many of our body’s varied distinct biochemical reactions. These include protein synthesis, muscle and nerve operations, as well as blood glucose stability, and blood pressure regulation. It is a necessary mineral for energy production, oxidative phosphorylation as well as glycolysis.  It is essential to healthy bones and it is absolutely needed for synthesis of DNA and RNA. It is also very much needed for antioxidant glutathione operations. It helps move calcium and potassium ions through cell membranes. What does that mean exactly? It is a key factor in muscle contraction and preserving a normal heart rhythm.

With all these benefits it is clear to see why this essential mineral is so important to our daily lives and our body’s effective functioning that when one is deficient, there could be dire symptoms.  What could these symptoms and chronic illnesses be? Try diabetes for one, and that is a disease that is ravaging people in modern times. Poor absorption, chronic diarrhea, celiac disease, and hungry bone syndrome. Hungry bone syndrome, what is that!?  It is basically a problem with bones that have a hard time retaining calcium when they have been demineralized. So, if you have any of these symptoms or are diagnosed with poor levels of this vitamin there are products out there on the market that can help you up your levels. To navigate the market on which product is best for you, remember to read the labels, look for purity, determine ingredient safety, and lastly, calculate the value of the product being offered.

1 pill is 500 mg


Large round pills are hard to swallow

May cause drowsiness

The truth of the matter is that taking in this extra of this mineral is generally safe for the majority of the population, there have been cases of those that have normal kidney functioning experiencing toxicity.  However, these cases were mostly people who had higher risk factors than the general public. If you are a regular consumer of antacids or laxatives, you may want to think twice about supplementing and really be serious about checking with your doctor to see if it is at all necessary.  The elderly in particular is the greatest risk category. People in advanced age tend to be taking many other medications, they may not figure out dosages correctly, and they get more dehydrated faster than their younger peers. These factors are all risks of toxicity.

So what is the final thought?  You should try to get as much of this mineral from the foods you eat first and foremost. Foods that are rich in it include spinach, potatoes, swiss chard, pumpkin seeds, black beans, avocados, mung beans, bananas, almonds, broccoli, cashews, and brussels sprouts. That is a list from most nutrient dense to least, spinach has 157 mcg per cup when cooked versus brussels sprouts that have 32 mcg per cup cooked.  If you are still deficient, then absolutely yes should you look into supplementation. Magnesium is a seriously crucial part of supporting your body’s functioning. It is directly involved in over 300 biochemical actions within you. If you experience any side effects like diarrhea, nausea or cramping while you are taking the aid, this is a good indicator you may be taking in too much.

Criteria Used In Choosing the Best Magnesium Supplements

Value Calculations

There are two things to consider that are available to you, magnesium citrate or magnesium glycinate.  Most times you can expect to get these in 400 mg servings. These, however, are simply magnesium compounds.  Which means they will always ionize apart before they bind together. You don’t want them to bind together because then they won’t bind well to the cells.  What does that mean in layman’s terms? Well, the best cellular absorption you could get would be at about 20%. That kinda sucks. If you are taking in 400mg, at that rate you are really only taking in 80 mg.  The rest that is available is not used or absorbed by your body, therefore you are losing any additional support and effectiveness. Then there is how well your body will absorb that 80 mg, which, realistically, only a small percentage of that 80 mg makes its way into your cells.  This is because it is not a stabilized ion of magnesium.

Safety of recipes

This aspect cannot be stressed enough.  The ingredients you are taking into your body should be safe for you. You need to know the types of medications you are regularly on so that you can determine if what is found in the formulations that you are taking will be ok for you or if they will cause negative interactions with your meds.  Be keenly skeptical of brands that offer elemental magnesium levels that could, in one dollop would go far beyond the established amount of 350 mg per day. What this shows is that the formulation was not developed by trained medical professionals and do not follow established FDA guidelines.

The symptoms associated with magnesium toxicity are generally nonspecific.  Which means basically that they can mimic other health issues and can throw you and your healthcare provider for a loop.  Nausea and weakness are the first to show through, but as time progresses, these symptoms will just get worse and worse. After some time, and extensive progression and worsening of these symptoms you may actually start having neurological issues like confusion, extensive musculoskeletal weakening, and even slurred speech. Herein lies the problem with taking nutritional aids.  Sometimes the things you want to use them for to sort out and balance your body could, in turn, be toxic for you depending on your meds and your amounts. You really need to familiarize yourself with what you put into your body. As with this mineral, the symptoms of toxicity aren’t clear-cut and can lead to you gaining intensity of these manifestations that will cause you great harm and distress before the actual culprit is correctly diagnosed.


If a manufacturer boasts a certificate of authenticity that will ensure the purity levels.  It shows you the least amount of chemical toxins and heavy metals associated with the manufacturing and formulation.  Titanium dioxide, for example, is a common ingredient in these mineral supplements that is an insoluble whitening agent.  Sounds scary, and it should! This is a substance the US Food and Drug Administration labels “Generally Recognized as Safe.” but what about when it is not safe?  Titanium dioxide is not innocuous. Research has shown that this compound can cause both cancer and neurological damage. Yikes!

Read the label

Even the all natural options should still have their ingredients inspected to ensure that what is in there won’t be an irritant to you.  All natural doesn’t automatically mean you can’t have bad side effects. These supplements are not meant to be taken forever. The reality is that you need to familiarize yourself with the ingredient lists and the label.    Look into quality assurance, ingredients, the brand and company that manufactures the drug’s reputation and quality, and possible side effects. Many times these products can use mixtures that are not that readily absorbed by your body.  They may only provide you with such a tiny bit of elemental magnesium that they would assuredly not make much impact on boosting your body’s supplies. If you want to know what the top three most sought-after formulations include they would be magnesium citrate, magnesium oxide, and finally, magnesium glycinate and the chloride forms.  

There was a recent study done assessing these different forms.  What was found was that the glycinate form (an amino acid chelate) had a much higher bioavailability than inorganic options such as the oxide form.  All in all, magnesium chloride ranked the best. In clinical trials, the chloride form of this mineral had the best and most absorption.

Other Important Factors to Consider

If you are a chronic sufferer of migraine headaches you may want to look into this mineral. Due to its involvement in neurotransmitter function and blood circulation, it can actually reduce your pain.  It releases pain-reducing hormones and limits vasoconstriction (raises blood pressure). There are so many studies available that have found that people who suffer from this ailment improve with magnesium supplementation.

Magnesium does so much it is really incredible when you take the time to look into it. It boasts all the powers we stated already but that is not all.  If you are having trouble sleeping, it can help you here too! Good, restorative sleep, as everyone knows is just essential, to every single human beings’ health and wellness.  Poor sleep jeopardizes so many functions of our natural body and puts us in such stress management mode that we can really get sick without it. These supplements can calm your senses and relax your mind so you can get to bed easier.  There was a study done that used this mineral over an 8 week period. Want to know what happened? The participants that used magnesium had an exponential increase in their melatonin levels, and since melatonin is the hormone that helps you sleep, along with less cortisol (the stress indicator), slept the best and had far superior sleep than their placebo counterparts.  Pretty cool.


Frequently Asked Questions

Q:  I am not regular and have heard this can help me poop! Is it true?

Actually, the answer is yes.  It will relax those muscles in the digestive tract as well as the intestinal wall.  These groups control your ability to either relieve yourself or make it hard to do. Magnesium neutralizes stomach acid so stool moves smoothly within the intestines. Altogether, what you get is a really great way to get rid of your waste.  Yes, it will help you relieve yourself in the poop form!

Q: Does the thyroid lead to Hungry Bone Syndrome?

Unfortunately for those of you who have had to have your thyroid removed, research shows that this syndrome is found present in those who had to have their thyroid removed.  People like this will generally get a bone disease because they exhibit high turnover with too high levels of the thyroid hormone or estrogen therapy.

Q: What role does this mineral play in anxiety and depression?

It has a large part in functioning to keep your mind in balance and healthy, believe it or not.  It is absolutely crucial for GABA function which produces “happy hormones.” These include serotonin.  Magnesium regulates some hormones that will help to cause tranquility in the brain and help with restoration and relaxation.  When your levels are right, you are able to sleep well, but when they are not, you won’t be able to and suffer from sleeplessness or insomnia.  There is nothing good that can come to a human being when they aren’t properly rested. Depression, anxiety, irritability, loss of focus, and drive are all just some symptoms of not getting enough sleep.  But this mineral promotes a healthful sleep and is why it can really help with all of these cognitive issues. There truly is no better medicine than a good, restful, night’s sleep.
