Episode notes
Magnesium's Core Role And Topical Route
- Magnesium underpins nerve signaling, muscle relaxation, and clear thinking so deficits cause fatigue, poor sleep, cramps, and blood sugar issues.
- Topical magnesium offers a direct skin route that can calm pain pathways and relax tight muscles quickly.
Evidence For Oral And Topical Benefits
- Oral magnesium links to better sleep and fewer leg movements, while topical trials show symptom improvement in fibromyalgia and raised blood levels in non-athletes.
- A pilot cream study found non-athletes' blood magnesium rose nearly 23% in two weeks, indicating meaningful skin absorption.
Find And Maintain Your Oral Dose
- Find your oral threshold using magnesium citrate by increasing until stools loosen, then back down slightly to set your dose.
- Maintain with glycinate, melate, or threonate to avoid digestive upset while keeping benefits.
