It's a generalized effect of supporting multiple systems in the brain and body.

So it's going to be a long time, maybe never, before you see a really nice clean study that says that, okay, increasing the amount of lactobacillus in the gut by taking X number of milligrams of lactobacillus improves your cognition.

You're not gonna find that study.

Why?

Because in science it's important and in health to distinguish between moderating effects and mediating effects.

Lots of things can moderate

a given feature of your brain or health.

So for instance, if a, you know, God forbid a fire alarm went off tonight, it would moderate our tension or excuse me, modulate, modulate Kentucky's in California.

And now I'm saying moderate, modulate our,

your attention, but it doesn't mediate attention.

On a normal basis, you know, the fire alarm isn't involved in your attention, whereas certain other things mediate those mechanisms of attention.

So when you improve sleep, you're going to see positive effects on any number of things.

When you sleep deprive people, you're going to see

in any number of things.

These are not direct effects.

These are indirect effects.

Likewise with the microbiome.

So I think gut microbiome sits in the various what I call pillars of mental health, physical health, and performance.

These are the things that we should try and tend to on a regular basis to give buoyancy to our mental health, physical health, and performance.

But I wouldn't get too caught up in wondering which exact
