Best Magnesium Supplements in Canada (Tested)

Magnesium supplements range from excellent to useless. The form matters more than the brand. Here is what eight weeks of comparing Canadian-available options taught us.

How we compared

We looked at form (glycinate, bisglycinate, citrate, oxide), elemental magnesium per dose, NPN, third-party testing, and price per 100 mg elemental.

Our four picks

CanPrev Magnesium Bisglycinate 200 — NPN certified, bisglycinate, 200 mg elemental per capsule, competitive price.

Pure Encapsulations Magnesium Glycinate — premium priced but third-party tested, glycinate form.

AOR Mag Malate — strong for fatigue; malate form with 150 mg elemental per capsule.

Natural Factors Magnesium Bisglycinate — budget option with NPN and widely available at Canadian pharmacies.

Skip these

Most generic magnesium oxide (poorly absorbed, better as a laxative). Multi-ingredient “sleep formulas” with sub-therapeutic magnesium doses.

The bottom line

For most Canadians: CanPrev Magnesium Bisglycinate 200 is the best balance of form, dose and price. For fatigue: AOR Mag Malate.
