"1000 mg magnesium" on the label. You absorb 40.
For 20 years I managed stress the way a chef does: by gritting my teeth. Dinner rushes, double services, four-hour
nights. I learned to push through. I never learned to recover.
Today I build Apexzen: single-ingredient supplements for people who actually read labels.
My first article answers a question I asked myself a thousand times: which form of magnesium actually works for
sleep?
Glycinate, threonate, citrate. Three powders on the same shelf, sold for the same job. They are not the same
compound. And the big milligram number on the front means nothing without the form.
Three things I wish I'd known sooner:
- Only one form has real human sleep trials behind it. The other two ride its reputation.
- "1000 mg" of oxide at 4% absorption = 40 mg actually absorbed. A well-chosen 250 mg glycinate capsule delivers
more than double.
- Dose and timing matter more than the brand.
No miracle promise in the article. Just the trials, the doses that match them, and the three marketing traps to spot
before you buy.
Four-minute read. Link in the comments.
Honest question: before reading this, did you look at the form of your magnesium, or just the big mg number on the
front? Tell me in the comments, I read them all.
A label-reader's guide to the only magnesium form with real human sleep data, the exact dose, and the marketing traps that waste your money. Short answer: for sleep, take magnesium glycinate (also sold as bisglycinate), 200 to 400 mg of elemental magnesium, 60 to 90 minutes before bed.
