best magnesium supplements

Magnesium, popularly called a “master mineral,” is one of the essential minerals present in our body. It plays an important role in bodily functions, with nearly 1000 enzymes relying on magnesium to maintain these functions. 

But here’s the problem. Half of the US population, including kids and adults, do not consume enough magnesium, be it through food or supplements.

Even the World Health Organization (WHO) reported that about 60% of adults worldwide do not meet their recommended daily intake of magnesium.

Hence, deficiency is something we shouldn't overlook. This is because magnesium deficiency can lead to uncomfortable or sometimes serious symptoms like fatigue, depression, and arrhythmia.

If you believe you, too, have magnesium deficiency, a magnesium supplement is just what you need. 

There are hundreds of supplements available on the market, and selecting the right one can be overwhelming. So, if you are searching for the best magnesium supplements, this blog is for you. 

Read on as we explain magnesium supplements in detail and their importance. 

Overview of Magnesium

Magnesium, also known as “master mineral” or “miracle mineral,” is crucial to cellular functions in our body. Generally, magnesium is found in green vegetables, whole grains, nuts, breads, and beans. They are considered as natural sources of magnesium. 

Yet, many people consume these foods less often. Over-processing has also reduced the natural magnesium content within these foods.

As a result, people do not meet the minimum daily requirement for magnesium, but they can benefit from magnesium supplements. 

What’s more, magnesium is a key player in the synthesis of DNA, RNA, and proteins, essential processes for growth, repair, and overall cellular function.

It also acts as a natural relaxant, helping to alleviate stress and improve sleep quality. With its involvement in such a huge number of bodily functions, the importance of maintaining adequate magnesium levels becomes evident for both physical and mental well-being.

How much magnesium should you consume? 

The table below shows the recommended Daily Allowance (RDA) for magnesium according to age and gender.

Benefits of Magnesium Supplements 

Magnesium brings tons of benefits to the table, which are associated with bone, nerve, and heart health. Some of the primary advantages of magnesium include:

Nerve health: Magnesium is a chief player in the transmission of nerve impulses and the contraction and relaxation of muscles. If you have enough magnesium levels in your body, it helps in the smooth functioning and coordination of these important physiological processes.

Bone health: For those who don’t know, magnesium is an important part of our bone tissue. Along with calcium and vitamin D, it supports bone density and prevents serious conditions like osteoporosis and arthritis. What’s more, magnesium improves blood flow to help deliver oxygen to your body tissues. 

Energy production: Magnesium is an essential cofactor in converting food into energy. It ensures that your body's energy production mechanisms run well. This, in turn, helps you in fighting fatigue and weakness.

Heart health: Research has shown that magnesium is highly important in maintaining a healthy heart. It mainly helps regulate blood pressure and supports the heart's rhythm. 

Stress Management: Magnesium has been linked to mood regulation and stress reduction. Its calming effects on the nervous system make it a potential ally in managing anxiety and promoting relaxation.

Reduced risk of migraine: People with migraine have low levels of magnesium in their blood. Studies have proved that supplemental magnesium may help lower the intensity of migraine headaches.

How To Choose The Best Magnesium Supplement? 

If you are confused about picking the best magnesium supplement for your diet, the answer is simple. It all depends on your age, sex, dosage, side effects, and cost. 

Most importantly, focus on finding a third-party-tested supplement and making sure that the product has the ingredients listed on the label. 

i). Check if it has been tested by a third party: 

Although unnecessary, it would be best to check if any third-party company has tested the brand you picked. 

This is important because the FDA doesn't regulate dietary supplements in the same way as drugs. That’s why you must look for brands that are certified by third-party organizations like NSF or USP. 

ii). Decide the type of magnesium you need: 

Some forms of magnesium, like magnesium malate, magnesium citrate, and magnesium glycinate, are easier for the body to absorb. You should know what your body needs to get the most benefits.

So make sure to decide on the type of supplement before buying. You can ask your dietician to recommend which one suits your body. 

iii). Look for the amount of magnesium it provides. 

Pick a magnesium supplement that does not exceed 100% of daily value (DV). This is because you likely consume some magnesium via food throughout the day, so less is OK. 

iv). Check the dosage: 

Make sure that the product provides an appropriate dosage of magnesium. Too much or too little can affect its effectiveness and result in possible side effects. 

iv) Check the bioavailability: 

Do not forget to check the bioavailability of the supplement when buying. Bioavailability basically shows how well your body can absorb and utilize magnesium for functioning. Higher bioavailability means better effectiveness.

Last but not least, avoid supplements that contain any types of artificial ingredients, including colors, flavors, and preservatives. 

After all these considerations, if you're still skeptical about what to pick, ask a healthcare professional or a nutritionist to recommend the most suitable one for you.
