Top Signs That You Have Magnesium Deficiency and What To Do About It

4. Anxiety, Irritability, or Mood Swings

Magnesium plays a role in calming the nervous system and regulating neurotransmitters like GABA. Low levels can increase stress, irritability, and even panic attacks.

Tip: Consider magnesium-rich evening meals or supplements to support relaxation and better sleep.

5. Trouble Sleeping or Insomnia

Magnesium helps activate the parasympathetic nervous system, which promotes deep, restful sleep. Deficiency may lead to difficulty falling asleep or staying asleep.

Solution: Magnesium glycinate or magnesium citrate before bed may improve sleep quality (consult your doctor before starting supplements).

6. Headaches and Migraines

Studies show that low magnesium levels are linked to chronic headaches and migraines because magnesium helps regulate blood vessel dilation and nerve signaling.

Tip: Adding magnesium-rich foods or supplements can reduce migraine frequency in some people.

7. Numbness or Tingling in Hands and Feet

Nerve function depends on adequate magnesium. Low levels may cause tingling, numbness, or a “pins-and-needles” sensation.

Action: Get a blood test to check for deficiencies and discuss supplementation with your doctor.

8. High Blood Pressure

Magnesium helps relax blood vessels, promoting smooth blood flow. Deficiency may lead to elevated blood pressure and increase the risk of heart disease.

Solution: Combining magnesium intake with potassium-rich foods like bananas and avocados can naturally support healthy blood pressure.
