What is Magnesium Glycinate?

Magnesium Glycinate is a chelated form of magnesium, where the mineral is bound to the amino acid glycine. This pairing produces one of the most bioavailable and gentle-on-digestion forms of magnesium available, with high absorption and low gastrointestinal side effects compared to magnesium oxide or magnesium citrate.

Why Magnesium Glycinate for Sleep?

Magnesium plays a role in over 300 enzymatic reactions, including those that regulate the nervous system, muscle relaxation, and sleep architecture. Magnesium Glycinate combines magnesium with glycine, an amino acid that supports calm and deeper restorative sleep.

Magnesium Forms Compared

  • Magnesium Glycinate: High bioavailability, gentle on digestion, best for sleep and recovery.
  • Magnesium Citrate: Good absorption but may have laxative effect at higher doses.
  • Magnesium Oxide: Cheap but poorly absorbed (around 4 percent bioavailability).
  • Magnesium Amino Acid Chelate: Bound to multiple amino acids for synergistic absorption.

Magnesium Dosage Research

The NZ RDI for magnesium is approximately 320 to 420mg per day for adults. WIIP Muscle Relax+ provides 400mg of elemental magnesium per serve, sourced from Magnesium Glycinate (360mg) and Magnesium Amino Acid Chelate (40mg).

Magnesium Safety

Magnesium from supplements is generally well-tolerated up to 400 to 500mg per day. Excess magnesium may cause loose stools, more common with magnesium oxide or citrate, less with glycinate. Consult your healthcare provider if you have kidney disease or take prescription medication.
