Expert Positions
The Verdict
4 of 5 experts actively recommend magnesium supplementation. Patrick and Hyman are the strongest advocates, each discussing it across multiple videos. Attia recommends 300-500mg daily for bone health and personally supplements with three forms. Johnson's Blueprint stack does not explicitly include magnesium.
Where They Disagree
Patrick cautions that magnesium threonate is a poor source for meeting daily RDA due to low elemental content — while the broader supplement community promotes it as a primary magnesium source.
Attia favors magnesium carbonate for best absorption and notes it's better absorbed than oxide, citrate, or glycinate — which contrasts with Patrick's recommendation of glycinate and malate.

About This Analysis
This consensus report on Magnesium is based on 17 videos (28 hours analyzed) from five longevity experts: Andrew Huberman, Peter Attia, Rhonda Patrick, Bryan Johnson, and Mark Hyman. Each expert's position was independently analyzed from their published video content, including lectures, podcast episodes, and Q&A sessions with 1,000+ guest scientists.
The full report includes 8 key findings, dosage and protocol details, expert deep dives with direct video citations and timestamps, risk considerations, and related supplement synergies.
Frequently Asked Questions
What's the best form of magnesium to take?
It depends on your goal. Patrick recommends glycinate or malate for general bioavailability, while Attia favors carbonate for the fullest absorption without speeding up the bowel. Threonate is for cognitive focus only — Patrick warns it's a poor source for meeting daily needs due to low elemental content. Citrate and oxide help bowel regularity as a side benefit.
How much magnesium should you take per day?
Experts converge on 300-500mg of elemental magnesium daily. Attia recommends 300-500mg as a minimum and calls calcium, vitamin D3, and magnesium 'the big three' for bone health. Patrick targets roughly 400mg and Hyman 400mg or more. Physically active adults need 10-20% more due to sweat losses (Patrick).
Does magnesium help with sleep?
The report supports magnesium for sleep. An evening dose is suggested for sleep support, and Hyman recommends magnesium to help sleep hygiene when quitting alcohol. Magnesium glycinate is commonly stacked with theanine and apigenin in Huberman's sleep cocktail — magnesium contributing muscle relaxation and GABA activity, theanine calming without sedation.
Can you take magnesium with vitamin D?
Yes, and they work better together. Magnesium is required for the enzymatic conversion of vitamin D into its active form, so without adequate magnesium, supplementing vitamin D may be less effective (Patrick). Attia groups calcium, vitamin D3, and magnesium together as 'the big three' for bone health.
Why do experts disagree on magnesium?
They largely agree it matters but split on form. Attia favors carbonate for best absorption over oxide, citrate, or glycinate, while Patrick recommends glycinate and malate. Hyman emphasizes a food-first approach; Patrick leads with the biochemistry of why supplementation is necessary. Johnson's Blueprint stack is the only one without explicit magnesium coverage.
