Experts often refer to magnesium as a “hidden hero” in nutrition due to its numerous health benefits. This essential mineral is important for energy production, blood sugar regulation, blood pressure management, and supporting both muscles and nerves, including the heart, according to the National Institutes of Health (NIH). Understanding the symptoms of magnesium deficiency can help you determine if you might need more of it.
“Magnesium is one of those under-the-radar minerals that quietly supports hundreds of vital processes in the body,” notes Samantha Peterson, R.D., founder and CEO of Simply Wellness.
Although magnesium deficiency is somewhat uncommon, studies show that about 48% of Americans aren’t getting enough, largely because many do not consume enough vegetables, which are naturally high in magnesium. This lack is further complicated by the fact that processed foods often lose their mineral content during refinement, as explained by Erin Barrett, Ph.D., director of product innovation and scientific affairs at Shaklee.
In fact, some individuals have a greater need for magnesium than others, according to Amy Davis, R.D.N. These include older adults, people with certain health conditions (like gastrointestinal issues or type 2 diabetes), and those on specific medications, all of whom may struggle to absorb adequate amounts of magnesium, according to the NIH.
Considering that symptoms of magnesium deficiency are often subtle, it can be tricky to recognize a deficiency. However, experts suggest several indicators that your body might be in need of more magnesium.
Fatigue
Feeling excessively tired or weak? Low magnesium could be a factor. “Magnesium is crucial for generating ATP, the energy molecule in your cells,” Barrett says. A deficiency impairs your body’s ability to utilize energy, potentially leading to feelings of fatigue. If your tiredness feels persistent and doesn’t improve with rest, as Matt Landry describes, it’s worth considering magnesium levels.
Muscle cramps and spasms
Insufficient magnesium can lead to muscle cramps, twitching, and spasms. In severe situations, it might even lead to seizures. Barrett points out that magnesium plays a role in regulating calcium and potassium, nutrients affecting muscle and nerve function. Low levels can make nerves and muscles overly excitable, resulting in unusual sensations or cramps, especially nighttime ones.
Anxiety or irritability
Feeling unusually anxious or irritable? Check if your magnesium is adequate. According to Peterson, magnesium calms the nervous system and helps control neurotransmitters that impact mood. Low magnesium might leave you feeling tense or on edge as your brain enters overdrive.
Irregular heartbeat
If you notice an irregular or racing heartbeat, it’s a good idea to consult a healthcare provider. Low magnesium levels could disrupt the electrical stability of your heart, which can lead to such irregularities.
Headaches
Frequent headaches or migraines might indicate low magnesium levels, particularly if they seem to be more common lately. Barrett explains that magnesium influences nerve signaling and blood flow in the brain, and a deficiency could increase the risk of migraines for some people.
Trouble sleeping
Even if you’re getting enough sleep, low magnesium can still affect your energy levels and sleeping patterns. You might feel “wired but tired” or struggle to unwind at night, which highlights the need to evaluate your magnesium intake.
High blood pressure
Since magnesium helps manage blood pressure, a lack of it might elevate your risk of hypertension. Barrett clarifies that magnesium works by relaxing blood vessel walls, aiding in circulation and maintaining normal blood pressure levels. Increasing magnesium intake via diet or supplements might help lower your blood pressure and decrease your risk of heart-related issues.
Mood swings
Experience unexplained mood changes or feelings of depression? This might be linked to low magnesium levels. As magnesium affects neurotransmitters and the stress response, a deficiency can lead to emotional instability.
Digestion issues
Low magnesium may also affect your digestive health, potentially resulting in symptoms like constipation. However, it’s essential to look for additional signs, such as fatigue or muscle cramps, for a clearer picture of your health.
Sugar cravings
If you find yourself craving sweets, low magnesium might be at play. Magnesium helps regulate blood sugar levels, and insufficient magnesium can lead to imbalances, making it harder to maintain healthy blood sugar.
Weak bones
Magnesium plays a vital role in bone health. It supports the structure of bones and is crucial for regulating calcium and vitamin D. Over time, a deficiency can weaken bones, leading to conditions like osteoporosis.
The bottom line
The silver lining? If low magnesium is indeed your issue, consuming more magnesium-rich foods could alleviate your symptoms. Alternatively, magnesium supplements may also help. It’s advisable to discuss your health concerns with a medical professional, who can conduct a blood test to assess your magnesium levels and develop a personalized action plan for you.
