Magnesium glycinate and bisglycinate

Glycinate is about 14 % magnesium, so 1,000 mg of it gives you about 141 mg. Here’s what to check, then every glycinate we list, by cost.

What it is

Magnesium bound to two glycine molecules. Glycine is small, but still heavy next to magnesium. So 100 mg of magnesium takes about 710 mg of glycinate.

Names on Australian labels

  • Glycinate, bisglycinate, diglycinate, with or without “chelate”: all the same.
  • Magnesium amino acid chelate: glycinate only if the label names glycine. If not, we file it as “amino acid chelate”.
  • Buffered glycinate: usually mixed with oxide. That’s a blend, on the blends page.

What to check on the label

  • The magnesium figure, after “equivalent to” or “from”. A front figure such as 1.1 g is usually the compound.
  • Both figures printed? Multiply the compound by 0.141. Much more than 14 %? Look for a second compound, such as oxide.

Why it matters to you: glycinates differ a lot in magnesium per serve, so compare cost per 100 mg below. Whether glycinate suits you is a question for a pharmacist.

Every glycinate product listed, by cost per 100 mg

2 of 5 could be checked against their own figures (why the others can’t be).

Sorted by cost per 100 mg of magnesium, lowest first, until you sort. 5 products so far, added a few at a time, so not the whole market. No brand or retailer pays for inclusion, placement or marks.

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.

How to read this list

“Label says” and “Our maths” are the magnesium you actually get per serve, not the compound weight. Labels call it elemental magnesium. “Cost per 100 mg” is what that magnesium costs, so small and large doses compare fairly.

  • Sort by cost per 100 mg to see what the magnesium itself costs.
  • Open a form page to compare like with like.
  • Tick two products to see them side by side, or open one to see the working.

“Label says” is the magnesium per serve from the source we read: the pack, the brand’s page or a shop listing. “Our maths” is the compound weight × its share of magnesium. “Adds up” means the two are within 15 %. Cost per 100 mg uses the stated magnesium and each shop’s newest RRP or regular shelf price. It shows the lowest. “Price used” is that price, with its pack and date. We don’t use sale or member prices. No RRP or regular price yet? Then there’s no cost, and the product sorts last. Prices older than 35 days say “may have changed”. What the marks mean. How we work out each figure.
