FAQs

What is elemental magnesium?

The portion of the compound that is actual magnesium. A 1,000mg dose of magnesium bisglycinate provides roughly 140mg elemental magnesium.

Why compare on cost per 200mg elemental?

200mg sits inside the typical adult supplemental range, so it's a fair benchmark across brands with very different bottle and serving sizes.

Is bisglycinate the same as glycinate?

Functionally, yes — most UK products labelled glycinate are bisglycinate (two glycine molecules bound to one magnesium ion).
