Magnesium Glycinate Supplements Australia

Magnesium glycinate is magnesium bound to the amino acid glycine. It is often sold as a chelate, such as magnesium bisglycinate, rather than as a mineral salt like magnesium oxide or citrate. Because glycine adds weight to the compound, a gram of magnesium glycinate contains less elemental magnesium than a gram of magnesium oxide.

People usually look for this form because a practitioner has suggested it, or because they want magnesium bound to an amino acid rather than as oxide or citrate. It also suits people choosing between magnesium on its own and magnesium combined with other ingredients in a single product.

Key principle: Compare the elemental magnesium per serve, not the weight of the magnesium glycinate compound, and check which other ingredients come with it.

How to choose between Magnesium Glycinate products

The main choice is whether you want magnesium glycinate by itself or as part of a formula with other ingredients.

  • Single nutrient: Seeking Health Magnesium Glycinate Powder contains only magnesium bisglycinate. As a powder, you can measure a smaller or larger serve, and any other nutrients can be chosen separately.
  • Magnesium with one added ingredient: Therapure My Mag Mind pairs 100 mg of elemental magnesium with 200 mg of theanine, an amino acid found in tea, in a capsule.
  • Multi-ingredient evening formula: Switch Nutrition Sleep+ combines magnesium glycinate with ashwagandha, hops, zinc, vitamin B6 and vitamin C, for people who prefer one product over several.

If you already take zinc, B vitamins or herbal products, start with the single-nutrient powder so you don’t double up, and if in doubt, your practitioner is the best guide.
