Those who continued the extract maintained their improvement for 26 additional weeks. 

The effect didn’t fade. It held.

This is also why chamomile tea produces only a brief, mild effect. 

The ingredient is right. The dose is never there.

So now we have two compounds reaching the calming system through two different mechanisms. 

But GABA reaches the brain by more than one route — and there’s a second pathway neither of these ingredients activates. 

Leaving it unused means leaving calming support on the table.

GABA — A Second Route to the Same Destination

Fourteen controlled studies have looked at what happens when people take oral GABA for stress. 

A 2020 review published in Frontiers in Neuroscience analyzed them together. 

The results pointed consistently in the same direction: calmer stress responses, reduced physiological markers of tension...

While researchers noted that more studies are still needed to fully establish the picture.

What makes GABA’s story interesting is how it likely works. 

GABA doesn’t appear to cross directly into the brain in large amounts. 

Instead, researchers believe it acts on receptors in the gut lining — triggering a calming signal that travels upward through the vagus nerve, the communication line between your digestive system and your brain.

Your gut, in other words, may be talking your brain into calming down.

That’s a very different route than L-theanine, which raises GABA levels directly inside the brain itself. 

One works from the top down. The other from the bottom up. 

Same destination, two distinct paths. That’s not redundant. That’s additive — and it’s why combining them produces something neither achieves on its own.

Three ingredients now. 

Three different mechanisms. 

And yet there’s still a gap. 

All three depend on something more fundamental — a mineral the nervous system uses to transmit the calming signal once it arrives.

Magnesium — Rebuilding What Time and Stress Wear Down

Magnesium plays a quiet but essential role in how your nervous system communicates. 

It helps regulate the signals that tell your brain and body to stand down — and without enough of it, those signals don’t arrive with the strength they should.

Here’s what chronic stress does to your magnesium stores that most people never hear about. 

Under sustained stress, stress hormones cause magnesium to be released from your cells and excreted through the kidneys faster than normal. 

The longer the stress continues, the more you lose. 

And here’s where it compounds: lower magnesium makes the nervous system more reactive to stress — which drives more stress hormones, which depletes more magnesium.

Researchers who study this have a name for it: the magnesium-stress vicious circle. 

A self-reinforcing loop that can run quietly in the background for months or years without anyone connecting the dots.

Most people try to address this with a magnesium supplement and feel nothing. 

The problem usually isn’t the magnesium. It’s the form. 

Magnesium oxide — found in most inexpensive supplements — is poorly absorbed, with absorption rates found as low as 4%. 

Most of what you take passes through without being used.

The formula I use us Albion®-chelated magnesium bisglycinate: the chelation binds magnesium to glycine, an amino acid that itself supports nervous system function. 

More of what you take actually reaches the tissue that needs it.
