Compare elemental magnesium first

This is one of the most important numbers on a magnesium label. A supplement may contain a large amount of a magnesium compound, but only part of that weight is magnesium itself.

Elemental magnesium is the amount of magnesium the product actually provides.

These numbers describe different things. Do not compare compound weight with elemental magnesium as though they were equivalent.

READ THE FULL LABEL

Check what form you are actually getting

Magnesium glycinate and magnesium bisglycinate are commonly used names for magnesium bound to glycine. But products using those names are not necessarily formulated in the same way.

NON-BUFFERED

Magnesium glycinate is the magnesium source

For shoppers specifically looking for glycinate without another magnesium form added, the complete medicinal ingredient list should make that clear.

BUFFERED

Another magnesium source is also included

Some products combine magnesium glycinate with a source such as magnesium oxide. The front label may not tell the full story.

01Magnesium source

Is the form clearly identified?

02Elemental amount

How much is provided per capsule or serving?

03Other forms

Is another magnesium source included?

04Other ingredients

What else is in the capsule?

CANADIAN PRODUCT LICENSING

In Canada, look for the NPN

Natural health products licensed for sale in Canada receive an eight-digit Natural Product Number, or NPN, from Health Canada.

Use the NPN to verify the product name, licence status, medicinal ingredients, ingredient amounts, authorized uses, recommended dose, non-medicinal ingredients, and risk information.

Useful habit: Do not stop at seeing an NPN on the bottle. Search the number yourself and compare the public record with the product label.
04
LOOK BEYOND THE FRONT

Marketing language is not a substitute for label clarity

Terms such as premium, advanced, or maximum strength may sound impressive. A transparent label answers more useful questions.

1

How much elemental magnesium am I getting?

2

What magnesium form provides it?

3

What else is in the capsule?

4

What is the recommended dose?

5

Can I verify the Canadian product licence?

6

Are the quality claims specific and supportable?

OUR SELECTION STANDARD

What we look for in a magnesium glycinate supplement

We prioritize six practical criteria. They are shown before our product recommendation so you can apply the same standard to any label.

01

Elemental dose transparency

The amount of elemental magnesium should be easy to identify.

02

Formulation transparency

The magnesium source and every other ingredient should be clearly listed.

Non-buffered formulation

For shoppers seeking glycinate without another magnesium source, this should be clear.

04

Canadian product licensing

The product should have an identifiable NPN with a matching public record.

05

Verifiable quality information

Manufacturing and testing statements should be specific enough to substantiate.

06

Practical label information

Dose, capsule count, ingredients, and directions should be easy to understand.

FREQUENTLY ASKED QUESTIONS

Common questions before buying

Clear answers based on the label, Canadian product licensing, and the comparison standard used above.

What should I look for when buying magnesium glycinate in Canada?

Start with the elemental magnesium amount, magnesium source, complete ingredient list, recommended dose, and NPN. These provide more useful information than broad front-label terms such as maximum strength or premium.

Are magnesium glycinate and magnesium bisglycinate the same?

The terms are commonly used interchangeably for magnesium bound to glycine. The complete ingredient list still matters because products can differ in elemental dose, buffering, capsule ingredients, and serving size.

What does elemental magnesium mean?

Elemental magnesium is the actual amount of magnesium supplied by the product. It is different from the total weight of the magnesium compound. Nutritionn Magnesium Glycinate contains 1,450 mg of magnesium glycinate per capsule while providing 200 mg of elemental magnesium.

What does non-buffered magnesium glycinate mean?

In this context, non-buffered indicates that another magnesium form, such as magnesium oxide, has not been added as an additional magnesium source. Confirm this from the full medicinal ingredient list rather than relying only on the front label.

What is an NPN?

An NPN is an eight-digit Natural Product Number associated with a natural health product licence issued by Health Canada. You can search it in the Licensed Natural Health Products Database and review the public record.

Is Nutritionn Magnesium Glycinate licensed in Canada?

Health Canada's public database lists Magnesium Glycinate under Nutritionn with active NPN 80137688.

How much elemental magnesium is in each capsule?

Each capsule provides 200 mg of elemental magnesium from 1,450 mg of magnesium glycinate.
