Let me tell you something uncomfortable about last night.

While you were sleeping — or trying to — your brain was supposed to be running its cleaning crew. A system called the glymphatic system. Think of it as a night shift that floods your brain with fluid and flushes out the day's waste.

One of those waste products? Beta amyloid. The exact protein that builds up in Alzheimer's patients.

Every single night, your brain either clears it out — or lets it pile up.

That's not a slow, decades-away problem. That's last night. And the night before. And every night you slept badly and shrugged it off.

But it gets worse.

During REM sleep, your brain takes everything you learned that day and moves it from short-term to long-term storage. Skip the REM? The information just — disappears. Gone. Like it never happened.

Your brain also pumps out growth hormone during deep sleep. That's your cellular repair kit. No deep sleep, no repair.

So when you wake up foggy and slow, it's not just tiredness. Your brain didn't clean itself. Your memories didn't consolidate. Your cells didn't repair.

And this compounds. Night after night after night.

Here's the thing. Every supplement I'm going to show you works better when your sleep is backing it up. Magnesium l-threonate — which we'll get to — actually helps with deeper sleep. But the habits matter just as much as the pills.

If you want the full breakdown on how to fix your sleep — the environment, the habits, the complete sleep stack — ask me about the sleep journey.

Your brain does its most important work when your eyes are closed. Make sure it can actually do the job.
