Full Disclosure

Here are 12 scientifically proven magnesium health benefits and some easy methods to increase your intake.

1. Are involved in a myriad of biochemical reactions within your body

Magnesium is a mineral that can be found all over your body. Every cell of your body has minerals that are required for proper functioning.

Around 60% of the magnesium you consume is located in bones. The remainder is found in soft tissues, muscles and in fluids, such as blood.

One of its major functions is that it acts as a cofactor as a molecule that assists for the biochemical processes that are constantly that are carried out by enzymes. It is involved in over 600 bodily reactions which include:

  • Creation of energy by converting food into energy
  • Protein creation by forming new proteins using amino acids
  • Gen maintenance Helping to make and repair DNA as well as RNA
  • Muscle movement help in the contraction of muscles and relaxation
  • Regulation of the nervous system Controlling neurotransmitters that transmit messages to your nervous system and brain

Yet, research suggests that around 50 percent of U.S. adults get less than the recommended daily dose of magnesium.

It is possible that you require more magnesium while exercising in comparison to when you're at rest in accordance with the exercise.

Magnesium aids in the movement of blood sugar into the muscles and eliminates lactate that builds during exercise and leads to fatigue.

Studies have shown that magnesium supplements could help improve fitness levels in older adults and those suffering from deficiency of this essential nutrient.

A past study involving 2,570 women found that more magnesium intake with greater muscular mass and strength.

In a study in 2019 that included professional male cyclists who consumed 400 mg of magnesium a day for 3 weeks showed improvement in the recovery of muscles and protection against muscle damage during race that was strenuous, as compared to cyclists who were given placebo.

But, more research is requiredsince some studies suggest that supplementation doesn't benefit those who are active or have adequate levels of magnesium.


Numerous studies have shown that magnesium supplements improve exercise performance, but the results are not conclusive.

3. May combat depression

Magnesium plays an essential role in the brain's function and mood as low levels can lead to a higher likelihood of depression.

A study in 2020 concluded that stress can reduce magnesium levels, thereby increasing susceptibility to depression and stress.

In a brief study lasting just 8 weeks in a small study, taking 500 mg of magnesium daily produced significant improvement in the symptoms of depression for those who have a shortage of this mineral.

Additionally, a study of 6 weeks with 126 subjects discovered the consumption of 248 mg magnesium each day reduced symptoms of anxiety and depression regardless of the the status of magnesium.


Magnesium deficiency could be related to depression. This means that supplementation could aid in reducing symptoms of depression.

4. May support healthy blood sugar levels

Research suggests that around 48% of those suffering from type 2 diabetes suffer from low levels of magnesium in their blood which could affect our body's capability to manage blood sugar levels properly.

Furthermore, research suggests that those who take in more magnesium have an lower risk of getting Type 2 Diabetes.

A separate study discovered that magnesium supplements helped improve various cardiovascular risk indicators such as triglyceride, LDL (bad) cholesterol HDL (good) cholesterol and systolic blood pressure levels, specifically in people who suffer from a magnesium deficiency.

But, further research is requiredsince other studies have found no impact that magnesium has on cholesterol levels or the levels of triglycerides.


Magnesium could aid in lowering blood pressure and decrease risk factors to heart attack. But, more research is required.

6. It boasts anti-inflammatory properties.

Insufficient magnesium intake can lead to an increase in inflammation which plays an important role in the aging process and chronic illness.

A review of 11 studies found that magnesium supplements reduced the levels of C-reactive proteins (CRP) which is a sign of inflammation in those who suffer from chronic inflammation.

Other studies have similar results and show that magnesium supplements could lower CRP levels and other indicators of inflammation, like interleukin-6.

In addition, some research links magnesium deficiency with increased the stress of oxidative that is linked to inflammation.


Magnesium is known to fight inflammation by reducing markers like CRP as well as interleukin-6.

7. May help prevent migraine attacks

The headache of migraines is very painful and can trigger nausea, vomiting, and sensitivity to noise and light.

Certain researchers believe that those who suffer from migraines are at a higher risk to have magnesium deficiencies.

A number of studies have suggested that magnesium supplements can even help prevent or help with migraine-related headache.

In a previous study, adding 1 gram of magnesium gave relief from migraine attacks that were acute faster and more effectively than the usual medication.

Consuming more magnesium-rich food items could aid in reducing migraine-related symptoms.


Patients suffering from migraine could have low levels of magnesium. Certain studies suggest that supplementing with magnesium can aid in reducing migraine attacks.

A few studies suggest that magnesium supplements can help ease PMS symptoms and other issues like menstrual cramps, and migraine attacks.

This could be due to the fact that magnesium levels fluctuate through the menstrual cycle, causing worse PMS symptoms for women with an insufficient. Therefore, supplements can aid in reducing intensity of PMS symptoms such as menstrual migraines.

A study showed that 300 mg magnesium daily decreased the symptoms of depression, bloating and anxiety in students in college with PMS when in comparison with the control group.

However, more current, high-quality studies are needed to determine if this mineral could help alleviate symptoms regardless of magnesium levels.


A few studies indicate that magnesium supplements can to alleviate PMS symptoms, but further research is needed.

Magnesium is vital in maintaining bones' health and preventing the loss of bone. In reality, 50 to 60 percent the magnesium in your body can be located in your bones.

Certain studies link the mineral's lower levels with a greater risk of developing osteoporosis. It can cause bones to become brittle and weak.

A 3-year study conducted on 358 patients undergoing hemodialysisan intervention to get rid of excess water and waste from blood found that those who consumed the lowest amount of magnesium suffered triple the amount of fractures as those who had the most magnesium intake.

Furthermore, a analysis of twelve studies found consumption of high levels of magnesium to an increase in osteocalcification in the hip as well as the neck of the femur, both areas vulnerable to fracture.


Magnesium is essential for bone health. Studies link an increased intake of magnesium to a lower risk of fractures, osteoporosis, and bone loss.

10. Might help you sleep better

Magnesium supplements are commonly employed as a natural treatment for sleep disorders like insomnia.

This is due to magnesium's role in controlling various neurotransmitters that are involved in sleep like the gamma aminobutyric acids.

One study of insomnia sufferers aged over found that magnesium supplements decreased the time required to get to sleep by 17 minutes on average.

A second study of more than 4000 adults found that increased consumption of this mineral increases the quality and duration of sleep.

Intensifying your intake of magnesium via food or supplements can help with specific sleep problems and improve the quality of your sleep.

A similar study of 6 weeks found the consumption of 248 mg of magnesium every day significantly decreased anxiety symptoms.

Another study suggests that magnesium deficiencies could increase your body's susceptibility towards stress. It could increase the severity of anxiety symptoms.
