What is magnesium?
Magnesium is an essential mineral: your body needs it and can't make it. About half of it sits in your bones and most of the rest in soft tissue. Less than 1% is in your blood.
Ours is magnesium glycinate, magnesium bound to the amino acid glycine.
What it does
- Muscle and nervesSupports normal muscle and nerve function.
- EnergyHelps the enzymes that turn food into energy.
- BonesPart of bone structure, and helps maintain calcium balance.
- RelaxationSupports relaxation and restful sleep.

What people take it for
Some evidence
Early days
Early daysHow long it takes
Magnesium builds up slowly in your bones and cells. Give it a couple of months, not a couple of days.
- HoursAbsorbed through your gut, with any extra leaving through your kidneys
- WeeksYour bones and cells slowly fill back up
- About 3 monthsWhen most people in studies saw a change
How long it stays in your body
Your body keeps blood magnesium steady on its own, topping it up from your bones and clearing extra through your kidneys.
What's in a capsule
One capsule holds 133 mg. Blood pressure studies used closer to 368 mg a day, and food adds to your total too.
Forms, and how your body handles it
Ours is glycinate, which tends to be gentle on the stomach. Which form suits what, and how much to take, is in the full guide.
A normal blood test doesn't always mean you have enough. Your body pulls magnesium from your bones to keep your blood level steady, so you can run low without it showing.
What it interacts with
- Osteoporosis medicines (bisphosphonates)Keep them at least 2 hours apart, or you'll absorb less of your medicine.
- Some antibiotics (tetracyclines, quinolones)Take the antibiotic at least 2 hours before magnesium, or 4 to 6 hours after.
- DiureticsSome lower your magnesium and others raise it, so ask your doctor.
- Acid-reducing medicines (PPIs)Over a year or more, they can lower your magnesium.
- High-dose zincVery large amounts of zinc can get in the way of magnesium.
Goes well with
- TheanineOften paired in evening routines.
- D ComplexMagnesium helps your body use vitamin D.
- Calcium CitrateThe two work side by side in bone and muscle.
Side effects
- High amounts can cause loose stools, nausea and cramps.
Check first if
- Kidney disease: your kidneys clear the excess, so ask your doctor first.
- Pregnancy or breastfeeding: check with your doctor.

Questions
What is magnesium good for?
It helps your muscles, nerves, bones, energy and relaxation. People most often take it for sleep, muscle and blood pressure.
How long does magnesium take to work?
It's slow. Give it a couple of months. Blood pressure studies looked at about 3 months.
Can a blood test tell me if I'm low?
Only partly. Your blood level stays steady even when you're running low, so a normal result doesn't rule it out.
