Introduction:
Magnesium is an essential mineral that plays a vital role in various bodily functions, including muscle and nerve function, energy production, and bone health. High-energy organs in your body include the heart, brain, and liver. Despite its importance, magnesium deficiency is quite common and can have significant effects on our overall health and well-being. In this blog post, we will explore the prevalence of magnesium deficiency, discuss dietary sources rich in magnesium, and delve into different forms of magnesium supplements available on the market. So let’s dive in!
Section 1: Understanding Magnesium Deficiency
How common is Magnesium Deficiency?
Magnesium deficiency is more prevalent than you might think. In fact, it is estimated that around 50% of people in the United States and Europe are not meeting their daily magnesium requirements. Factors such as poor diet, certain medications, digestive disorders, and excessive alcohol consumption can contribute to this deficiency. People with certain medical conditions and athletes require higher amounts than minimum daily recommendations.
Symptoms of Magnesium Deficiency
Recognizing the symptoms of magnesium deficiency is crucial in addressing the issue promptly. Common signs include muscle cramps, fatigue, irritability, restless leg syndrome, poor sleep quality, and irregular heartbeat. Additionally, low magnesium levels may increase the risk of developing conditions such as osteoporosis, hypertension, and type 2 diabetes. Let’s focus on a few specific organ systems.
Muscle twitches, cramps, and tremors are signs of magnesium deficiency. If the deficiency is severe, enough seizures or convulsions may occur. Studies suggest these symptoms are caused by a greater flow of calcium into nerve cells, which overexcites or hyper-stimulates the muscle nerves. Just remember that there are other very common causes for involuntary muscle twitches including stress or excessive caffeine. Other causes include a side effect of some medications or a symptom of neuromuscular disease such as muscular dystrophy, multiple sclerosis, or myasthenia gravis.
There are mental health conditions such as apathy with mental numbness or lack of emotion associated with low magnesium. Stress, depression and anxiety may be other signs of magnesium deficiency. One study suggests magnesium supplementation with a form of magnesium that is well absorbed into the brain may help (see supplementation section below). Magnesium supplementation may help with sleep as well. Magnesium contributes to the regulation of neurotransmitters, such as serotonin and GABA, which are involved in mood regulation and anxiety management.
Magnesium deficiency is a risk factor for osteoporosis. Osteoporosis is a disorder characterized by weak bones and an increased risk of bone fractures. Inadequate amounts of magnesium directly leads to weaker bones and lowers calcium levels, which is the main building block for the bones. Other nutrients that help support the bones include vitamin D and K.
Severe or persistent fatigue along with muscle weakness may indicate magnesium deficiency. Fatigue is a broad term and often refers to both physical or mental exhaustion and weakness. If rest and magnesium supplementation do not help with muscle weakness or fatigue, other considerations including infection, electrolyte abnormalities / low blood count, or thyroid issues may need to be examined.
Animal studies show that magnesium deficiency may increase blood pressure and promote high blood pressure, which is a strong risk factor for heart disease. Human studies may be on going but research reviews show that magnesium supplements may lower blood pressure, especially in people with high blood pressure.
Many people with asthma have magnesium deficiency. It has been shown that is common in people with severe asthma. Inhalers with magnesium sulfate can help reduce mild asthma symptoms while an intravenous form of magnesium sulfate can be effective for severe exacerbations. Dietary magnesium supplements may depend on the type and amount of absorption.
People with irregular heartbeats or arrhythmia may have magnesium deficiency the source or one of the sources for the problem. Arrhythmias can be without symptoms or be noted as palpitations that may be felt as pauses between heartbeats. In severe cases of arrhythmias, there may be an increased risk of stroke or heart failure.
Here is a table for the National Institutes of Health on the Recommended Dietary Allowances (RDAs) for Magnesium. Please note certain medical conditions may need adjustments and athletes may need more.
