Frequently Asked Questions About Magnesium Supplements

What Is Magnesium?

Magnesium is a mineral that plays a number of important roles in the human body. It’s a vital component of proper bone health and structure, heart health, circulatory health, and much more.

It plays a key role in energy production, supports the immune system, regulates blood glucose levels, and more.

In fact, magnesium is involved in more than 300 biochemical processes in the body. It plays a key role in a wide variety of reactions and natural processes within the human body, and without it, our bodies simply would not function properly.

What Are Some Sources of Magnesium?

Magnesium is found naturally in foods and is also available in supplement form. Some common foods with magnesium include dark leafy greens, like spinach and kale, nuts and seeds, fish, whole grains, bananas, dairy, and more. If you eat a healthy, balanced diet there’s a good chance that you get enough magnesium on a regular basis from foods alone.

However, many people simply do not consume enough of these healthy foods in order to get enough magnesium in their diets. The USDA estimates that 57% of Americans do not consume enough magnesium. This deficit off such a key nutrient can lead to magnesium deficiency, which can cause all sorts of health problems.

And in fact, even if you do eat a healthy diet, you still may not get enough of this mineral. Over the years, magnesium and other minerals have been diminished from the soils we use to grow our crops, which leads to lower and lower mineral consumption among people – even those who eat a lot of veggies.

To help fight against these negative health effects of magnesium deficiency, many people take magnesium supplements to help increase their intake. Which leads us to our next section!

What Are Magnesium Supplements?

Simply put, magnesium supplements are health products that contain concentrated doses of magnesium in pill or capsule form (or sometimes magnesium powder). They provide an easy way to increase your daily consumption and help fight the low magnesium symptoms that many people suffer from.

You probably already take a daily multivitamin, which likely does contain some magnesium. However, most multivitamins don’t contain enough magnesium to meet the recommended daily intake, which ranges from 310mg to 420mg for adults, depending on age and sex.

As we said before, the USDA estimates 57% of Americans to have a magnesium deficiency, while some estimates put that number as high as 80%. If you’re concerned that you are a part of the majority, using a good magnesium supplement can help you get your health back on track.

It’s wise to speak to your doctor before beginning any new supplement or medication. With that being said, magnesium is relatively harmless as long as you take the recommended dose and no more.

It’s also important to note that not all of these products are equal – some are strong magnesium supplements with high doses, some offer lower doses, and some are just not as high quality as others and should be avoided.

What Are the Benefits of Magnesium?

Magnesium is a very important mineral that serves a lot of purposes in our body. With its involvement in 300+ biochemical processes, it would be impossible to list all the magnesium benefits here, but to start, we’ll take a look at the most significant health benefits of magnesium:

  • Helps to increase energy
  • Calms nerves
  • Improves sleep quality
  • Helps improve digestion
  • Relieves muscle aches & spasms
  • Helps to regulate calcium & potassium levels
  • Important for heart health
  • Regulates steady heartbeat
  • Prevents migraines
  • Helps prevent osteoporosis
  • Fights the effects of magnesium deficiency and low magnesium symptoms
  • May boost exercise performance
  • Helps fight depression
  • May help in the treatment of type 2 diabetes
  • Regulates blood pressure
  • Anti-inflammatory
  • Improves PMS symptoms
  • And more!

The list of magnesium benefits is quite long. Magnesium has been the subject of medical and scientific studies, and the benefits are plenty.

With that being said, different people will experience different effects from these supplements.

Those who are notably deficient will experience the most positive effects, while those who get enough magnesium in their diets may not notice any difference at all.

Who Can Benefit from Taking Magnesium?

Anyone who does not get enough of this mineral in their diet can experience benefits. Somewhere between 57% and 80% of Americans have a magnesium deficiency, so frankly, the majority of people can benefit from taking a supplement. With that being said, here are the groups of people that will notice the most changes:

  • Anyone with magnesium deficiency – a deficiency in this key nutrient is more common than you’d think, with at least 57% of Americans not getting enough on a daily basis. In fact, even if you eat a healthy diet and take a multivitamin, you’re still at risk for deficiency and the low magnesium symptoms that come with it. And even if you DO consume a decent amount of magnesium, you still may be at risk if you drink caffeinated beverages, eat sugar, or are affected by stress, as these factors can actually cause magnesium stores in your body to be depleted more rapidly.
  • Athletes and fitness enthusiasts – during exercise, your body needs 10-20% more magnesium compared to resting periods. This means that people who exercise often will need more magnesium than the average person. Plus, this mineral has actually been shown to boost exercise performance, with many studies showing promising results. Not to mention, magnesium also helps move blood sugar into your muscles, which in turn can help dispose of lactic acid buildup. Bottom line, if you’re an athlete or someone who exercises on a regular basis, you should be taking an effective magnesium supplement.
  • Those with high blood pressure – magnesium can help lower blood pressure, without the use of pharmaceuticals that can have serious side effects. With that being said, if you have high blood pressure you should absolutely be talking to your doctor about it – magnesium supplements are not a magic fix, but they certainly can help.
  • Aging individuals – aging is a natural process, but that doesn’t mean it’s easy! As our bodies age, we go through many changes, some of which can be unpleasant. In clinical trials, magnesium has been shown to improve physical performance in elderly people, and it provides powerful anti-inflammatory effects. Several studies have also shown an ability to improve sleep quality and lower inflammation in elderly folks.
  • Migraine sufferers – if you suffer from migraines, you don’t need me to tell you how unpleasant they can be. Studies have shown that magnesium deficiency has been linked to a higher rate of migraines in otherwise healthy individuals, while other studies have shown that top magnesium supplements can be effective for the treatment of migraines.
  • Women of childbearing age – if you are a woman of childbearing age, chances are you’re familiar with the effects of PMS. In several studies, magnesium has been shown to improve mood, reduce water retention, and combat many of the unpleasant effects of PMS.
  • Those with type 2 diabetes or insulin resistance – If you have been diagnosed with type 2 diabetes (or you’re at risk), you should speak to your doctor about taking some good magnesium pills. Magnesium helps to improve insulin’s ability to keep blood sugar levels normal. Additionally, magnesium has proven effective at improving insulin resistance in both people with diabetes and people at risk.

Clearly, a lot of folks can experience some very noteworthy benefits from these simple and effective health products. As with anything, we recommend you speak to your doctor before beginning any new supplement.

How Do I Take Magnesium Supplements?

If you’re wondering about magnesium dosage, when to take, etc. this is the section for you.

As for magnesium dosage, the recommended amount varies depending on your sex and age. Check the official RDAs for magnesium here.

In general, for healthy adults, the recommendation is between 310 and 420 mg per day. Males tend to need more than females, although females will need to increase intake during pregnancy and lactation.

Now, keep in mind that you likely already get some naturally – sources of magnesium include foods from your diet and/or from your multivitamin. Many multivitamins will contain around 100mg of magnesium, which is about ¼ of the recommended daily amount.

As for when to take it, magnesium is best taken on its own, ideally in between meals and not taken with other vitamins. Magnesium requires some stomach acid to absorb properly, so if you take it with a meal you may not benefit from ideal absorption.

With that being said, some people experience minor stomach discomfort when they take supplements on an empty stomach. If that happens to you, taking your pill at mealtime will not significantly affect the benefits of the supplement.

Additionally, magnesium can compete for absorption with other minerals and vitamins, which can lead to lower overall absorption rates. For that reason, it’s best to take your dose at a different time than you take other vitamins and mineral supplements.

You should always take the recommended dose, or less, and not take more than that unless instructed by your doctor. Generally speaking, magnesium products are quite safe and shouldn’t cause any adverse effects, but we highly recommend you speak to your doctor before taking any product.

Are There Any Side Effects of Magnesium?

Generally speaking, the best magnesium supplements won’t cause many side effects, so long as you take them as instructed and don’t take more than the recommended dosage.

When taking in amounts of ~400mg or less, magnesium is very safe and shouldn’t cause any negative effects. With that being said, everyone reacts differently to supplements, and some people have reported the following side effects of magnesium:

  • Upset stomach
  • Nausea/vomiting
  • Diarrhea

If you find that you experience any of these side effects, it would be wise to speak with your doctor to ensure that the supplement is not reacting negatively with other medications or supplements you may be taking. Also, sometimes cutting your dose in half can help, or taking the supplement with a meal to reduce stomach discomfort.

As always, more severe side effects are possible if you take too much. The most you should consume in a dose is 400mg. Anything more than that and you should speak to your doctor before proceeding. In fact, it’s a good idea to talk to your doctor anyways, before you begin taking any supplement.

How Do I Pick a Good Magnesium Product?

As with most products nowadays, there are tons of choices when it comes to selecting the right magnesium supplement for you.

To help you choose, we’ve compiled some helpful tips to keep in mind:

  • Amount of magnesium – first things first, take a look at the ingredients label and see how much is included in each serving. Typically, amounts will range from 200 to 400mg. 400mg is at the upper end of the recommended intake levels, so if you’re wanting to start slow with a smaller dose you may want to consider a lower magnesium dosage product. With that being said, you’ll also want to keep in mind the cost of each product and how it relates to the amount of the mineral.
  • Type(s) of magnesium – there are several different types of magnesium used in these products. Magnesium oxide, magnesium citrate, magnesium glycinate, and many more. While all of these types offer the same main perk – more magnesium in your system – they work slightly differently and absorb at different rates.
  • Other ingredients – some magnesium supplements also contain other minerals and vitamins, such as calcium, potassium, and more. These extra ingredients may or may not be necessary for you, depending on your situation.
  • Brand quality – who makes the product? What is their reputation? Are they a large, reputable company, or one you’ve never heard of? Our list of magnesium product recommendations contains products ONLY from top-notch companies, but if you shop elsewhere on the web or even your local supplement store, be aware that not all companies use the same quality standards or offer the same level of product quality.
  • Value – the last factor of note will be the value presented by the product, generally best calculated as a cost-per-serving figure. You’ll want to find something that fits within your budget, while still being a good quality product. Obviously don’t go for the cheapest option, necessarily, but keep cost in mind as you make your selection.
