What to know
Magnesium L-threonate is magnesium bound to threonic acid. It was developed for research into magnesium and the brain, and most of the evidence so far comes from animal studies and a few small human trials. The magnesium dose is modest at 144 mg, well under the 350 mg a day upper level for magnesium from supplements in Australia, so it can sit alongside a normal diet. It is not the cheapest way to raise magnesium intake. Compare it with our magnesium range if that is your main goal.
Who should check first
- Kidney disease: do not take magnesium supplements without your doctor's advice.
- Taking medication: take magnesium at least two hours apart from antibiotics, thyroid medicine and osteoporosis medicine.
- Memory concerns: see your GP. A supplement is not a treatment.
