The greatest athletes in the world all have this one secret mineral fuelling them. Yours is probably running on empty.
By the PuraVita Research Team, Updated September 2026
Every legend below ran on the same mineral. The drugstore sells you a version your body barely absorbs. This is what the top of sport actually used, in their own words.
All these athletes had one secret. While everyone else did the same workouts and took the same protein shake, these athletes knew something deeper inside them needed to fuel them.
Every athlete below reported magnesium as a main supplement in their stack. Some of them even brought it to their team to take through their championship years.
Five legends. One mineral.
Michael Jordan on the court.
1. Michael Jordan
"Michael takes at least 1g of magnesium daily. It helps him with recovery, energy levels and prepares him to perform. It's honestly like a cheat code."
Werner Shwankert, Jordan's nutritionist during the first and second 3-peat
Two three-peats on this mineral. PuraVita carries 700 mg of it, in 12 forms, in one nightly capsule.
Michael Phelps with his medals.
2. Michael Phelps
"90 days before the Olympics, Michael would up his dose of magnesium to 500mg per day. He was training every day, so recovery and support was boosted really well during those periods."
John Blue, Award winning sports nutritionist
Olympic volume drains the tank daily. 700 mg, 12 forms, one capsule before bed.
Mike Tyson in the ring.
3. Mike Tyson
"Mike was an animal in his prime. I remember he would chug water, take his magnesium capsules, and then chug water right after training. It was his recovery secret."
Don "The Snakeman" Jefferson, Longtime training partner
Camps this brutal leave the tank dry. 700 mg, 12 forms, before bed is what keeps recovery honest.
Kobe Bryant on the court.
4. Kobe Bryant
"Kobe learned from Jordan that magnesium was a non-negotiable for his stack. During the 3-peat, in the early 2000s, he would bring bottles for the whole team after every practice."
Lakers Sports Nutrition Staff, Team nutrition
Daily sessions empty the tank. 700 mg, 12 forms, one capsule before bed refills what the work takes out.
Cristiano Ronaldo on the pitch.
5. Cristiano Ronaldo
"Cristiano's been taking magnesium since he was 15 years old. He would show up to practice with the bottles in hand. One time I offered him a different bottle and he flat out refused. He said the right type of it matters more than just taking any random bottle."
Ronaldo's Trainer, Longtime training staff
Two hours of sweat drains it fast. 700 mg, 12 forms, before bed puts back what the ninety minutes takes.
And then there's you
No media day, no team nutritionist. Your season is the 5:40 alarm, the truck loaded before seven, the 2 PM wall at the desk, and your kid asking you to throw the ball after dinner while you are already eyeing the couch. Same mineral lost, nobody handing you the fix. That is exactly why you are reading this.
Skip these three first
The bottles the pros walk right past. If it is in your cabinet now, this is why it is not working.

Nature Made Oxide
Absorbs at ~4%. You flush the rest.

Doctor's Best
One form does one job. Not twelve.
Avoid
BioEmblem Triple
Three forms, still nine short.
One bottle. Twelve forms. The whole system.
The full spectrum in one capsule.
That level of output asks for full-spectrum coverage, not one form doing one job and clocking off. Most drugstore magnesium is a single cheap form the body barely absorbs, often oxide at 4% or less. You do not leave a recovery gap on a shelf that cheap. Twelve forms in one capsule, 700 mg a serving, covering calm, brain, energy, muscle and the nine systems the shelf ignores.
12 forms in one capsule, 700 mg per serving
Glycinate for calm, threonate for the brain, malate for mornings
