Are You Getting Enough Magnesium? Experts Say Active Adults Should Watch For These Subtle Warning Signs

In today’s generation, magnesium deficiency is more common than many people realize. In fact, some people may experience early warning signs for months and months without recognizing that their body is low in magnesium levels. Since the symptoms are often vague and easily overlooked, they are sometimes mistaken for everyday stress, fatigue, dehydration, or poor sleep.

Over time, low magnesium levels may slowly begin to affect several important functions in the body, as it plays a key role in muscle contractions, nerve signaling, energy production, heart rhythm, hydration balance, and even recovery after a workout. For active adults, getting enough magnesium becomes even more important because physical activity, constant sweating, poor dietary habits, and stress can all increase magnesium loss from the body.

According to Dr. Janine Bowring, in a Youtube Reel from her YouTube channel she states that – magnesium deficiency is more widespread among people than they think. She explains that modern eating habits, highly processed foods, chronic stress, digestive issues, and low intake of magnesium-rich foods are all contributing factors for magnesium deficiency.

On the other hand, health experts generally recommend around 310–420 milligrams of magnesium per day for most adults, while also depending on the gender, age and sex. Consequently, foods like pumpkin seeds, spinach, almonds, beans, avocados, and dark chocolate are some of the foods considered a better natural sources of magnesium.

Here are five subtle signs that may indicate that your body is not getting enough magnesium.

1. Frequent Headaches and Constant Fatigue

Dr. Janine says that if you often experience – recurring headaches, migraines, unexplained tiredness, and low energy levels, this may be a subtle sign of low magnesium in the body. She also adds that magnesium helps to support a normal nerve function and blood vessel regulation throughout the body. And when the magnesium levels are too low, some people may experience increased muscle tension, fatigue, or headaches more often than usual.

2. Digestive Discomfort

She also points out that magnesium supports healthy muscle contractions in the digestive tract. And low levels of Mg may contribute to symptoms such as nausea, constipation, stomach cramping, or irregular bowel movements. In some cases, digestive discomfort may become more noticeable during periods of stress or poor eating habits.

3. Muscle Cramping and Tingling Sensations

Muscle cramps, tightness, spasms, or unusual tingling sensations are commonly associated with magnesium deficiency. Dr. Janine highlights that consuming right amount of magnesium helps to relax those nerves and relax muscles. She also mentions that for this situation, magnesium bisglycinate is often preferred as an oral supplement because it is generally more comfortable for the stomach, and is commonly used to support muscle relaxation and nervous system function.

4. Eye Twitching

Dr. Janine says one of the most noticeable symptoms of low magnesium is the twitching of your eyelids. These are harmless signs, but a persistent eye twitching can sometimes be linked to stress, fatigue, caffeine overload, or low magnesium. And since magnesium helps to regulate the nerve communication, its deficiency may increase involuntary muscle contractions in some people.

5. Tension in the Neck and Shoulders

Dr. Janine also includes – If you are frequently feeling tightness in the neck and shoulders, bad posture is not always the cause. Again, it can be caused by low levels of magnesium, as Mg plays an important role in muscle relaxation and stress regulation, and low levels of Mg can contribute to increased muscle tension and stiffness over time.

Final Thoughts

Magnesium, as an essential mineral, may not receive as much attention as proteins or vitamins, but it remains one of the most important micronutrients for overall health, exercise recovery, muscle function, and daily energy levels. Dr. Janine highlights that – while the occasional symptoms like fatigue, cramps, headaches or muscle tension may always indicate magnesium deficiency, it may still be important not to ignore these signs.

For many active adults, simply improving food quality, staying hydrated, and including more magnesium-rich foods in the diet may help to support better overall health and recovery in the long run.
