From energy production & nerve communication to muscle movement, magnesium plays an important role in numerous bodily functions. But still, countless people suffer from a deficiency of this critical mineral. Even though our body sends us signals in forms like muscle cramps, headaches, and prolonged fatigue, many of us do not recognize them, making it one of the most common mineral deficiencies around the world. Meanwhile, in this blog, we will take a look at the signs that you need magnesium and the right way to take it to help you understand magnesium deficiency and tackle it.
Why Is Magnesium Deficiency So Common?
Magnesium is an important mineral in our diet. It can be found in every cell in your body. It is essential for hundreds of biochemical processes that aid in the production of proteins, the operation of muscles and nerves, the conversion of food into energy, and metabolism. Meanwhile, magnesium shortage rarely appears on routine blood testing until it is severe, in contrast to other nutrient deficiencies. Because maintaining stable blood magnesium levels is a top priority for your body, it will take magnesium from your bones and tissues before allowing blood levels to fall. Therefore, it is very important to understand the signs that your body is running low on magnesium and address it before it gets severe.
Signs That Your Body Is Running Low on Magnesium
Persistent Muscle Cramps
Perhaps muscle cramps are the most common symptom of muscle deficiency in your body. Issues like cramps, twitches, or even spasms after a workout session. Magnesium modulates muscular contraction and relaxation by controlling the influx of calcium into the muscles. Low magnesium levels cause muscle cramps because they alter electrolyte balance, calcium flow regulation, and nerve signal transmission. If you have cramps despite not having a heavy workout and having enough hydration, magnesium might be the reason.
Headaches
Magnesium deficiency can show up in various forms, and headaches or migraines are definitely among those. Low levels of magnesium can have a negative effect on blood flow to the area, as it is essential for dilating cerebral blood vessels. Thus, insufficient magnesium levels may contribute to all types of headaches by impairing neurotransmitter activity and blood circulation. According to studies, people who suffer from regular migraines tend to have lower magnesium levels. Many doctors advise individuals suffering from migraines to take magnesium supplements to aid with their headaches.
Sleep Issues
Magnesium has a relaxing impact on the brain and controls neurotransmitters necessary for sleep. It slows down nerve activity, which relaxes both your body and brain. Additionally, it controls the hormone melatonin, which regulates the cycle of sleep in your body. Thus, insufficient magnesium keeps your nervous system hypervigilant, which makes it hard to get a good night’s sleep. As a result, your day-to-day activities are affected.
Fatigue & Tiredness
Everybody gets fatigued from time to time. Usually, this just indicates that you need some rest. However, severe or prolonged weariness without any apparent reason may indicate magnesium deficiency. Magnesium is essential for energy production in the body, acting as a cofactor in the process of converting food into usable energy (ATP); hence, low magnesium levels cause weariness. In contrast to short-term exhaustion, magnesium-related fatigue frequently feels persistent and unwavering. If your energy levels have dropped unexpectedly, without actually doing much, it may be because of low magnesium levels.
Anxiety & Depression
Magnesium is essential for controlling the neurological system and maintaining optimal brain function. It aids in the regulation of neurotransmitters that influence your level of anxiety or calmness, including serotonin and GABA. Magnesium deficiency can cause mood swings, unexplained stress, anxiety, or even symptoms of depression. Many individuals with anxiety have been found to have low magnesium levels. Magnesium supplements have been shown to be useful for people suffering from anxiety problems.
Addressing Magnesium Deficiency
Above, we have discussed some of the ways in which your body tries to signal you about low levels of magnesium, yet there are several other symptoms that a deficiency of magnesium can cause. Since the human body can not produce magnesium on its own, the only way to fulfill it is through diet. Leafy green veggies like spinach, nuts & seeds, and grains like oats or quinoa are rich in magnesium. In addition, fruits like avocado, banana, dark chocolate, and yogurt are also a good source to incorporate magnesium.
Even though consuming a balanced diet that is rich in magnesium is a good way to address magnesium deficiency, it might not be enough for some people. That’s where magnesium supplements come in. These supplements ensure that you’re fulfilling your magnesium requirements through small tablets without having to make significant changes to your diet. An average adult needs around 400 mg of the mineral every day. However, it is always advised to consult your doctor before starting any supplements in order to avoid any problems down the road.
