Magnesium and the Immune System: Supporting Kids with Chronic Illness and Dysregulation

If your child struggles with chronic illness, anxiety, or frequent dysregulation, you’re not alone. Magnesium plays a crucial role in supporting the brain, nervous system, and immune system, especially for kids with PANS/PANDAS, chronic infections, Lyme, ADHD, anxiety, or mood challenges.

In this episode, Dr. Roseann explains how magnesium deficiency can impact emotional regulation, immune function, and stress responses, why some children are more susceptible, and how supplementation or dietary support can help create calm and improve resilience.

In this episode, you’ll learn:

• Why some children stay sick longer and how magnesium supports the immune system

• How magnesium impacts anxiety, emotional regulation, and dysregulation

• Signs of magnesium deficiency in children

• Which forms of magnesium best support the brain and immune system

• How magnesium reduces inflammation and promotes overall healing

Why does my child get sick so easily and stay sick longer?

Chronic infections and immune dysregulation are often worsened by magnesium deficiency. Magnesium supports:

• T-cell and B-cell activation
• Macrophage function (pathogen clean-up)
• Antibody production
• Balanced inflammatory responses

Parent story:

A mom shared that her daughter’s PANDAS flares became shorter and less severe after magnesium supplementation improved immune function.

Could low magnesium be worsening my child’s anxiety or dysregulation?

Absolutely. Magnesium regulates the nervous system, helping kids with PANS/PANDAS, chronic Lyme, ADHD, and other inflammatory mental health challenges.

Low magnesium may cause:

• Heightened anxiety and irritability
• Increased stress activation
• Poor sleep
• Attention and learning difficulties
• Emotional reactivity

Parent observation:

Once magnesium levels were optimized, children showed calmer mornings, smoother transitions, and fewer after-school meltdowns.

Which magnesium forms support the brain and immune system?

Not all magnesium supplements are equal.

Best options:

• Magnesium glycinate – crosses the blood-brain barrier; supports nervous system and immune regulation
• Magnesium citrate – gentle for digestion and detox
• Magnesium-rich foods – leafy greens, nuts, seeds, and whole grains

Takeaway: Choose magnesium based on function, not just availability.

How does magnesium reduce inflammation and support healing?

Magnesium’s anti-inflammatory effects make it a foundational tool for children with chronic illness or neurological dysregulation.

Benefits:

• Reduces excess inflammation and oxidative stress
• Strengthens intestinal and skin barriers
• Supports detoxification
• Protects DNA and supports repair mechanisms

Parent story:

A child experienced reduced brain fog and improved stamina after magnesium
