When to Take Magnesium — Expert Timing Protocols
Expert-analyzed timing recommendations for magnesium based on what 5 longevity researchers say about when, how, and what to take it with.
Quick Timing Guide
Smaller, frequent doses throughout the day for better absorption. Carbonate in the morning (Attia's protocol). Evening dose for sleep support.

on Magnesium overall
Full Protocol
Timing
Smaller, frequent doses throughout the day for better absorption. Carbonate in the morning (Attia's protocol). Evening dose for sleep support.
Dosage
300-500mg elemental magnesium daily (Attia: 300-500mg; Patrick: ~400mg; Hyman: 400mg+)
Form
Glycinate or malate for general bioavailability (Patrick). Carbonate for best absorption without GI effects (Attia). Threonate for cognitive focus only — don't count toward daily needs. Citrate/oxide if you want bowel regularity as a side benefit.
Notes
Standard blood tests for magnesium are unreliable — the body maintains plasma levels by drawing from bones, masking true deficiency (confirmed by both Attia and Patrick). Excessive zinc supplementation can inhibit magnesium absorption. Physically active adults need 10-20% more than sedentary RDA.
Expert Positions
What Each Expert Says About Timing
On the Huberman Lab channel, multiple guests discuss magnesium extensively. Dr. Rhonda Patrick identified magnesium as an essential mineral often lacking in the US population, emphasizing its role in ATP production and DNA repair enzymes. Dr. Mark Hyman discussed soil depletion reducing magnesium content in foods and shared a hospital anecdote about needing magnesium supplementation post-surgery. Dr. Andy Galpin noted that magnesium supplementation is recommended for roughly 90% of the athletes he works with, as exercise increases requirements and standard blood tests are unreliable indicators.
