Magnesium glycinate
Highly absorbable form of magnesium that supports sleep and relaxation.
Mentioned by Andrew Huberman, Peter Attia, Matthew Walker, and Anna Lembke
Overview
Magnesium is an essential mineral involved in hundreds of enzymatic reactions. Many people are deficient due to modern diets. Magnesium glycinate is chelated with glycine, making it highly absorbable and less likely to cause digestive issues than other forms.
What experts say
Andrew Huberman
Stanford neuroscientist
"Magnesium threonate or glycinate, 300 to 400 milligrams, 30 to 60 minutes before sleep, can significantly improve sleep quality. Most people are deficient in magnesium."
Anna Lembke
Stanford Addiction Medicine
"Magnesium can help with anxiety and is something I often discuss with patients as a foundational supplement."
Matthew Walker
Sleep researcher, UC Berkeley
"Magnesium plays a role in the regulation of sleep. Many people see improvements in sleep quality when they correct a magnesium deficiency."
Peter Attia
Longevity physician
"Magnesium deficiency is incredibly common. I recommend magnesium glycinate or threonate for most people, especially for sleep quality."
Our take
If you're going to take one supplement, magnesium is a strong candidate. Most people don't get enough from diet alone. Glycinate is the best form for sleep and anxiety—take 200-400mg about an hour before bed.
