Magnesium glycinate: why it became the supplement of the moment (and when it makes sense)
Suddenly everyone's a magnesium expert. Before you buy the first tub you see, let me separate real from hype — because the form of magnesium changes everything.
Why magnesium matters
It's a mineral involved in over 300 reactions: muscle and nerve function, glucose control, blood pressure and energy production. Outright deficiency is relatively uncommon, but below-ideal intake is frequent in people who eat lots of ultra-processed food and few vegetables, seeds and legumes.
Glycinate, citrate or oxide?
- Glycinate: bound to the amino acid glycine, well absorbed and gentle on the stomach. The favorite for sleep and relaxation — partly from glycine's own calming effect.
- Citrate: good absorption, versatile; in larger doses it's laxative (handy for constipation).
- Oxide: cheap but poorly absorbed. Much of what you pay for passes right through.
What to actually expect
Magnesium can help people with low intake sleep better, relax muscles and reduce cramps. What it is not: a magic pill that fixes insomnia caused by screens, caffeine and a wrecked schedule. Supplements come after the basics, not instead of them.
How to use it
- Common dose: 200 to 400 mg of elemental magnesium a day, at night if sleep is the goal.
- Food first: dark leafy greens, pumpkin seeds, nuts, beans and cacao are excellent sources.
- Caution: anyone with kidney disease should talk to a doctor first — the kidney regulates magnesium.
