What Is The Best Magnesium Supplement – Top 5 Reviews and Choices

| |

Magnesium plays an integral role in our health. If the body lacks magnesium, we, illnesses linked to bones and joints, especially children and older people, are prone to diseases related to bones and joints. Let's find out in the article below about the most popular magnesium supplements in the market and carefully choose the best magnesium supplement for you.

Why do we need to take magnesium?

Magnesium is a vital mineral that plays a crucial role in the health of our bodies, especially our brains. Magnesium is found in many foods, such as avocado, banana, dark chocolate, and spinach. Also, magnesium is found in some medicines (such as antacids and laxatives).

Magnesium is essential for energy production, oxidative phosphorylation, and the release of energy in sugar. It contributes to the development of the skeletal structure and is a crucial element for the synthesis of DNA and RNA. Magnesium also plays a vital role in transporting calcium and potassium ions across cell membranes, an essential process for nerve impulse conduction and muscle contraction. Let’s explore the massive benefits of magnesium thoroughly below.

#1. Magnesium is involved in hundreds of biological reactions in a human’s body

Every cell in the body contains magnesium, and our bodies need it to function. This mineral participates in more than 600 responses in our bodies, including:

  • Generating energy: Helps turn food into energy.
  • Protein formation: Food converted into use-able energy.
  • Gene maintenance: Assists in the creation and repair of DNA and RNA.
  • Muscle movement: is a part of muscle contraction and relaxation.
  • Regulating nervous system: Regulate neurotransmitters; the result is to help send messages in the brain and nervous system.

But, many studies show that about 50% of people in Europe and the US absorb less than the daily intake of magnesium recommended.

#2. Magnesium helps increase physical activities

You may need 10-20% more magnesium while doing exercises than taking a rest, and the exact figure depends on the activity you take part in. Magnesium helps transfer blood sugar to the muscles and removes lactic acid build-up in muscles, which causes you pain during workout sessions.

Researches have shown that magnesium supplementation enhances exercise performance for the elderly and those suffering from chronic illnesses.

#3. Magnesium helps fight against depression

Magnesium is important for brain functions. Low magnesium levels may cause depression. An analysis of more than 8,800 people showed that people under 65 with low magnesium intake were 22% more likely to suffer from depression. Consuming low magnesium foods is the cause of many types of mental illness and depression, some experts pointed out.

In a randomized trial of elderly people with depression, taking 450 mg of magnesium was proved to help improve mood as effectively as antidepressant medication. (See more about research )

#4. Magnesium helps fight against type 2 diabetes

About 48% of people with diabetes have low magnesium levels in the blood. This can lead to a decrease in insulin ability to control blood sugar. With diabetes taken high content of magnesium every day,  they can quickly improve their hemoglobin A1c (HbA1c) and blood sugar levels.

In other words, people who regularly consume magnesium are less risk of developing type 2 diabetes. However, this one relies on how much magnesium from food you get. You should know that supplements will provide more magnesium than your daily intake of raw food.

#5. Magnesium helps lower blood pressure

Magnesium involves chemical reactions in our bodies to regulate blood pressure and control the concentration of potassium and calcium in cells. Magnesium deficiency in the diet can cause high blood pressure.

One research shows that people taken 450 mg of magnesium daily had significantly reduced diastolic and systolic blood pressure. However, only people with high blood pressure enjoyed these benefits. (See more about research)

#6. Magnesium helps fight against inflammation

Low magnesium intake is one of the causes of chronic inflammation, one of the causes of  obesity, aging, and chronic diseases. One study pointed out that children have the highest levels of CRP inflammation if their magnesium levels are lower.

Magnesium can reduce CRP and inflammation (in the elderly), overweight, and prediabetes. As such, consuming foods high in magnesium may help reduce inflammation.

#7. Magnesium helps prevent migraine

Migraine sufferers often experience nausea and are sensitive to noise. You may find that migraine annoys your life in some ways.

In fact, magnesium can prevent migraines and even take part in migraine treatment. Supplementing your diet with only 1 gram of magnesium can reduce migraines faster and more effectively than conventional medicine. Plus, foods that are high in magnesium may help to relieve migraine symptoms.

#8. Magnesium improves premenstrual syndrome (PMS)

One of the most common disorders in women (childbearing age) is Premenstrual syndrome. Its symptoms include irritability, fluid retention, abdominal cramps, and fatigue. Fortunately, magnesium has been shown to improve mood in women with PMS and may reduce fluid retention and other symptoms.

#9. Other benefits of magnesium

Magnesium also keeps your bones and teeth strong through the activity of metabolizing many essential minerals. Magnesium stimulates the absorption of calcium into bones, prevents bone aging, osteoporosis in the elderly, and rickets in young children. Furthermore, it also prevents calcification (one of the causes of kidney stones).

So, one way to guarantee that we get enough magnesium is to add a magnesium supplement to our diet. But it turns out that there is more than one sort of magnesium supplement, and each kind serves different purposes.
