Essentials: Breathing for Mental & Physical Health & Performance | Dr. Jack Feldman

So it's not a good way to go.

Oh, it is a good way to go.

Huberman Lab
Essentials: Breathing for Mental & Physical Health & Performance | Dr. Jack Feldman

Couldn't help myself.

Well said.

So he worked with this brilliant chemist, Fei Mao, and Fei looked at a whole range of magnesium compounds and he found the magnesium threonate,

was much more effective in crossing the gut blood barrier.

Now, they didn't realize at the time, but threonate is a metabolite of vitamin C.

And there's lots of threonate in your body.

Huberman Lab

So magnesium threonate would appear to be safe.

And maybe part of the role, or now they believe it's part of the role of the threonate, is that it supercharges the transporter to get the magnesium in.

And remember, you need a transporter at the gut.

into the brain and into cells.

They did a study in humans.

Huberman Lab
Essentials: Breathing for Mental & Physical Health & Performance | Dr. Jack Feldman

They hired a company to do a test.

Huberman Lab
Essentials: Breathing for Mental & Physical Health & Performance | Dr. Jack Feldman

It was a hands-off test.

Huberman Lab

It's one of these companies that gets hired by the big pharma to do their tests for them.

And they got patients who were diagnosed as mild cognitive decline.

Huberman Lab
Essentials: Breathing for Mental & Physical Health & Performance | Dr. Jack Feldman

These are people who had cognitive disorder, which was age-inappropriate.

Huberman Lab
Essentials: Breathing for Mental & Physical Health & Performance | Dr. Jack Feldman

And the metric that they use for determining how far off they were is Spearman's g-factor, which is a generalized measure of intelligence that most psychologists accept.

And the biological age of the subjects was, I think, 51, and the cognitive age was 61, based on the Spearman-G test.
