What to know
This is a high strength capsule. The upper level for magnesium from supplements in the Australian and New Zealand Nutrient Reference Values is 350 mg a day for adults, so a single capsule is already above it, and the full label dose of three a day is far above it. The main effect of too much supplemental magnesium is loose stools, and oxide is the form most likely to cause this. If you want a gentler option with a smaller dose per tablet, compare our magnesium range.
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.
- Using other magnesium products: add up your totals.
How to use and where to buy
Most people should not need more than one capsule a day. Take it with food and cut back if you get loose stools. Shop Magnesium Caps 500 mg online at Supps247 with Australia-wide delivery or click and collect, or browse more from Life Extension.
