Bought magnesium and ended up running to the bathroom instead of drifting off to sleep? 👀 Oops. The form—and the dose—can make a difference.
Here’s how to choose:
🌙 SLEEP + WINDING DOWN → MAGNESIUM GLYCINATE
Also called bisglycinate, this form pairs magnesium with the amino acid glycine. It’s often well tolerated and a reasonable option to consider for bedtime support. Early research suggests modest sleep benefits as it can be calming and relaxing.
💩 OCCASIONAL CONSTIPATION → MAGNESIUM CITRATE
Citrate can draw water into the intestines, making stool easier to pass. The amount matters: a daily supplement and a bottle of magnesium citrate laxative are very different products! Too much can cause diarrhea and cramping.
Magnesium oxide can also have a laxative effect - often an even stronger water effect than citrate - be careful!
💪 SORE MUSCLES → REACH FOR MALATE
Magnesium helps muscles contract and relax, and low levels can contribute to cramps. Soreness doesn’t automatically mean you need more magnesium, but many magnesium malate users find it help improve muscle recovery and energy.
🧠 WHAT ABOUT L-THREONATE?
You’ll often see this form marketed for brain health. Human research is still developing, but this is the form most often used by those looking to improve brain health and cognition.
A few things I want you to remember:
• Check the ELEMENTAL magnesium amount on the Supplement Facts panel—not just the big number on the front.
• Get magnesium from food, too! - pumpkin seeds, almonds, beans, and leafy greens all contribute.
• If you have kidney disease or take medications, check with your clinician or pharmacist before supplementing.
Magnesium can be a helpful tool. Remember your nutrition, sleep habits, movement, and the reason behind your symptoms still matter too! 🤍
