Why Timing Magnesium Matters

Magnesium plays a central role in calming your nervous system, relaxing muscles, and managing cortisol — your body’s primary stress hormone. Taking it at the wrong time may blunt those benefits or even make you feel sleepy at the wrong time of day.

Best Time to Take Magnesium?
For most people, the ideal time is in the evening, about 1–2 hours before bed. That’s when your body is winding down and can use magnesium’s calming effects to support:

  • Muscle relaxation
  • Nerve regulation
  • Cortisol control
  • Deep, restorative sleep

How Much Magnesium Should You Take?

While 200–300 mg in the evening is often enough, many people — especially those under stress or with low pH balance — may need more.

“Some of my clients need 400–600 mg daily to hit the ideal pH range in their first morning urine,” says Dr. Susan Brown.

If you need higher doses, split them: take part in the evening, and the rest with meals throughout the day.

Bonus Tip: Magnesium and pH Balance

If your first morning urine pH is below 6.5, that could be a sign you need more magnesium. This mineral plays a central role in buffering acid and maintaining your body’s optimal pH range (6.5–7.5).
