Selection method

How we selected the shortlist

  1. Relevance: Dedicated magnesium products are prioritised while bath products and weak category overlaps are excluded.
  2. Availability: only published, currently in-stock products can render.
  3. Commercial safety: products must have recorded COGS and at least 25% GST-adjusted product margin.
  4. Useful variety: the shortlist covers meaningfully different formulations or formats and limits brand repetition.

Before you choose

What to compare on a magnesium product

Magnesium form

Read the ingredient panel to identify the magnesium compounds rather than relying on the front label.

Elemental amount

Compare elemental magnesium per suggested daily serve, not the total compound weight alone.

Delivery format

Powders, tablets, capsules and topical sprays have different instructions and are not direct dose equivalents.

Added ingredients

Flavours, sweeteners, vitamins and minerals affect how closely two products can be compared.

Common questions

Magnesium questions

What does “best” mean in this guide?

It means best matched to a stated shopping distinction within the current Nutrition Market catalogue. It does not mean clinically superior for every person.

Why are there fewer products here than in the full category?

The guide uses a narrow, reviewed manifest and removes out-of-stock, weak-fit and commercially unsafe products. The category remains the complete range.

How often is the shortlist checked?

The manifest expires after 90 days and can also change sooner when stock, pricing or product details change.
