Mineral

Magnesium Glycinate

Magnesium bisglycinate chelate

Moderate evidence

A gentle, highly absorbable form of magnesium — the mineral your nervous system uses to downshift. A favorite for evening wind-down, stress resilience and sleep quality.

Our pick, and why

Choosing a magnesium glycinate on iHerb

All three use Albion® chelates and deliver 200 mg elemental magnesium — so the form criterion is a three-way pass. The differentiators are format and value. Doctor's Best is our pick: same verified Albion® source, familiar tablet format, and the best value at 120 servings per container. NOW uses pure bisglycinate and is an equally solid choice at 90 servings. Thorne's powder is the gentlest on digestion and dissolves easily in water, but is less convenient for travel.

How we judge these

Bioavailable chelate form (glycinate or bisglycinate, not oxide), elemental magnesium clearly stated, named chelate source.

Magnesium sits at the center of the body’s “calm down” chemistry: it regulates the stress axis, supports GABA signalling, and modern diets are frequently short of it. Surveys suggest a large share of adults don’t reach recommended intakes — and chronic stress itself increases magnesium loss, creating an unhelpful loop.

The glycinate form pairs magnesium with glycine, an amino acid with its own calming reputation, and is the form most people tolerate best for daily evening use.

What to look for

  • “Magnesium glycinate” or “bisglycinate” on the label
  • The elemental magnesium amount per serving (often 100–200 mg per capsule)
  • Avoid “magnesium oxide” if your goal is absorption rather than regularity
