How much of the compound is magnesium
Only part of each compound is magnesium. Here’s that share for each one. Some compounds come in several versions, for example with water in the crystals. Each version has its own share.
- Magnesium glycinate: 14.1 % magnesiumThis name covers more than one version, and the brand’s product page doesn’t say which. We use our standard one.

Do the figures agree?
stated 150 mg vs our maths 155.1 mgdifference -3.3 % (band ±15 %)adds up
Yes. The brand’s product page gives 1,100 mg of compound and 150 mg of magnesium per serve. Our maths: 1,100 mg × 0.141 = about 155.1 mg. That’s within 15 % of the stated figure. Why it matters to you: the cost per 100 mg rests on figures that agree. It isn’t a lab test of what’s inside, but it’s the check a label can pass.
Third-party testing
no testing claim found
No testing claim or certificate on the brand’s product page. That’s true of most products here, and it isn’t a mark against this one. The TGA doesn’t check each product before it goes on sale. If batch testing matters to you, ask the brand.
Our note: Neither the brand’s page nor the Chemist Warehouse listing mentions testing (both read 27 Oct 2026). We looked for a HASTA (Human and Supplement Testing Australia) or Informed Sport listing or certificate naming this brand, and found none.
Prices, and what the magnesium costs
Prices are the recommended retail price (RRP), or the regular shelf price where no RRP is shown. Sale and member prices aren’t used, so you may pay less.
Price used: Regular price $43.99 · 200 tablets · Chemist Warehouse · 27 Oct 2026.
$43.99 ÷ 200 serves = 22c a tablet22c ÷ 150 mg × 100 = $0.15 per 100 mg of magnesiumWe use the stated magnesium, not our maths, because that’s the figure you’re given. The price used is the lowest current RRP or regular price we’ve seen, at any shop. The list starts with the lowest current cost per 100 mg; earlier prices follow. Rows marked “Earlier observation (price type not recorded)” were seen up to 27 Oct 2026, before we switched to RRP. Some were sale prices. They stay here, greyed, as history, and no figure uses them.

Notes
The Chemist Warehouse 100- and 200-tablet listings give the same figures. The brand’s page lists packs of 50 and 100 and 1 tablet a day; ARTG entry 520466 was active, opened 27 Oct 2026.
Corrections
- 27 Oct 2026: Label source changed from the Chemist Warehouse listing of the 200-tablet pack (Chemist Warehouse listing, 200 tablets (opens in a new tab)) to the brand's own product page (Blackmores product page (opens in a new tab)), read 27 Oct 2026; a brand's page ranks above a retailer listing. Figures unchanged: magnesium glycinate 1.1 g, magnesium 150 mg per tablet. Compound wording changed from 'Magnesium glycinate (magnesium 150 mg) 1.1 g' to the brand page's 'Magnesium glycinate 1.1 g, equivalent magnesium 150 mg'.
