MAGNESIUM Deficiency: 9 Signs You Should Know

Hello, this is Dr. Berry. Today, we’re going to delve into a common but often overlooked issue: magnesium deficiency. It’s a widespread problem, particularly in countries like the US, Canada, the UK, and Australia. Millions are unknowingly suffering from this deficiency, and it’s time we shed some light on it.

Why is Magnesium Important?

Magnesium is an essential mineral that plays a crucial role in over 400 biochemical reactions in our bodies. It’s vital for life, and our bodies can’t produce it on their own. We must obtain it through our diet or supplements. However, only 1% of our body’s magnesium is present in our blood, and our bodies regulate this amount very tightly. This means that even if your blood tests show normal magnesium levels, you could still be deficient in your cells, bones, and organs.

Signs of Magnesium Deficiency

Recognizing the signs of magnesium deficiency is the first step towards addressing it. Here are some symptoms to watch out for:

  1. Low Energy Levels: If you’re constantly feeling tired or low on energy, it could be due to a lack of magnesium. This mineral is vital for the production of ATP, the energy molecule in our bodies.
  2. Fast Heart Rates: Magnesium helps your heart relax. Without enough of it, you may experience a faster heart rate.
  3. Numbness or Tingling: Magnesium is critical for nerve function. A deficiency can lead to numbness or tingling in your fingers and toes.
  1. Muscle Cramps or Twitches: If you’re experiencing frequent muscle cramps or twitches, it could be a sign of low magnesium levels.
  2. Constipation: Magnesium can help with constipation. If you’re chronically constipated, increasing your magnesium intake might be beneficial.
  3. Insomnia: Struggling with sleep? Magnesium can help you achieve a more restful sleep. Taking 400 to 800 milligrams of magnesium at bedtime can help improve your sleep quality.
  4. Osteoporosis or Osteopenia: If you’ve been diagnosed with these conditions, it could be due to a lack of magnesium. This mineral is essential for proper bone formation and calcium storage.
  5. High Blood Pressure: Sometimes, high blood pressure is caused by low magnesium levels. Taking 400 to 800 milligrams of magnesium at bedtime every night can help lower your blood pressure naturally.
  6. Arrhythmias and Atrial Fibrillation (AFib): Many heart arrhythmias are caused by low magnesium levels. If you’re experiencing heart palpitations or have been diagnosed with AFib, increasing your magnesium intake might help.
  7. Severe Morning Sickness in Pregnancy: Severe morning sickness could be due to a magnesium deficiency. Some studies show that taking a magnesium supplement can help reduce the severity of morning sickness.


Magnesium deficiency is more common than you might think, and it can lead to a variety of health issues. If you’re experiencing any of these symptoms, it might be worth considering increasing your magnesium intake through diet or supplements. As always, consult with your healthcare provider before starting any new supplement regimen. Stay healthy and informed!
