Most people think salmon is the gold standard for omega-3s…

It’s not.

At I found one of the most underrated nutritional powerhouses out there: Sablefish (aka Black Cod) — and it blows salmon out of the water.

We’re talking ~40% more omega-3s.

Why does that matter?

Because omega-3s are not just “healthy fats”—they’re foundational to how your body actually functions:

• Reduce systemic inflammation
• Support brain clarity + mood
• Improve cardiovascular health
• Help balance hormones
• Support recovery + longevity

And here’s the part most people miss…

You can’t out-supplement a bad diet.

This is real food. Real nutrients. Real impact.

Sablefish is rich, buttery, insanely satisfying—and one of the easiest upgrades you can make if you’re trying to heal, perform, and actually feel good again.

And let’s be honest…

If you’re going to invest in your health, why not also invest in your community?

Support local farms. Know your food. Upgrade your biology.

👉 Next time you’re at Sweetland Farm—grab the sablefish.

Your brain, heart, and future self will thank you.

RFK Just Forced the FDA Into a Corner… And Peptides Might Finally Break Free

Everyone thinks peptides are getting banned.

They’re wrong.

What’s actually happening?

👉 The system is being forced to fix itself.

For years, peptides like:
BPC-157
TB-500
Thymosin Alpha-1

Have been stuck in limbo—

Not approved.
Not accessible.
But used anyway.

So what did people do?

They went underground.

“Research use only”
Grey market vials
No oversight
No quality control

Let’s call it what it is:

That’s not medicine. That’s desperation.

Now RFK is applying pressure—and if this July shift happens…

We could see up to 14 peptides move back into regulated compounding.

Which means:

➡️ No more guessing what you’re injecting
➡️ No more sketchy sourcing
➡️ Real medical oversight
➡️ Actual protocols that make sense

And here’s the truth nobody’s saying—

Peptides were never the problem.
The broken system was.

When you block access, you don’t stop demand…

You just push people into risk.

This could be the moment that flips everything.

Not just for peptides—

But for how medicine actually gets practiced.

⸻

I’m curious—

What’s the one peptide that actually made a difference for you?

Not hype. Not theory.
Real-world impact.

👇 Drop it below + what you noticed (energy, recovery, sleep, gut, etc.)

Let’s compare notes.

Just wrapped up an incredible conversation on 101.3 WYKR with Josh—and we went straight at one of the biggest health crises of our time:

👉 The obesity epidemic.

No fluff. No sugarcoating.

We broke down:
• Why the current “one-shot fix” mindset is missing the bigger picture
• Where GLP-1s and peptides can be powerful tools
• And the real drawbacks no one’s talking about

Here’s the truth most people aren’t hearing:
Weight loss isn’t just about suppressing appetite—it’s about fixing metabolism, hormones, inflammation, and the root causes driving the problem in the first place.

That’s the conversation we need to be having.

Grateful for the opportunity to bring a more nuanced, root-cause perspective to the airwaves—and this is just the beginning.

🎙 I’ll be back regularly with Josh diving into different health topics you actually care about.

Make sure you tune in Fridays
We’re just getting started.

🚨 “You don’t need labs before starting hormone therapy.”

That’s not progressive medicine.
That’s clinical laziness dressed up as confidence.

Let’s get real for a second…

We’re talking about putting powerful hormones into a human body — and some clinicians are just guessing?

No baseline.
No roadmap.
No understanding of where that patient is starting from.

That’s like flying blind and calling it precision.

Here’s what actually happens when you skip labs:

→ You miss underlying dysfunction (thyroid, cortisol, insulin resistance)
→ You mask root causes instead of fixing them
→ You create side effects that could’ve been avoided
→ You have ZERO objective way to measure if treatment is working

And the wild part?

Patients are being told this is “standard.”

No. It’s just common. And common is not the same as correct.

At GrassRoots, we don’t guess.

We measure.
We interpret.
We build a strategy based on physiology — not trends, not shortcuts, not ego.

Because hormones aren’t just about feeling better today…
They’re about protecting your brain, your metabolism, your long-term health.

If your provider isn’t testing before they treat…

You’re not getting optimized care.
You’re getting a gamble.

And your health deserves better than that.

If this is what being a “quack” looks like… 🦆

A guy on stage wearing a glowing red brain helmet talking about optimizing human performance while the rest of medicine is still arguing about symptom management…

Yeah… I’m good with the label.

Because here’s the truth nobody wants to say out loud:
The “quacks” are the ones actually asking better questions.

👉 Why are patients still exhausted, inflamed, and metabolically broken despite “normal labs”?
👉 Why are we managing disease instead of reversing dysfunction?
👉 Why does innovation get mocked before it gets adopted?

Every breakthrough looks ridiculous… right before it becomes standard of care.

So call it weird.
Call it fringe.
Call it quackery.

Meanwhile, we’ll be over here:
• Using light to influence mitochondrial function
• Personalizing care instead of protocolizing people
• Actually helping patients feel alive again

And if that makes us a little unconventional?

Perfect.

Because nobody ever healed by playing it safe.

🦆 Proud to be a “quack” — especially if it means staying on the cutting edge of what actually works.

Breathing hydrogen at a Longevity conference in Hollywood FL… what could go wrong? 😂🚀

Real talk—this is one of the more interesting things I’ve seen in a while.

Potential benefits:
• Energy ⚡
• Brain clarity 🧠
• Recovery & Sleep 🔥

So now I’m curious…

👇 Would YOU try hydrogen therapy?

And bigger question—

👉 Should we bring this to the Upper Valley?”

04/09/2026

A little more Texas in the Upper Valley this morning 🤠🐂

We’ve got a new Longhorn heifer calf at the Barn.

Up, moving, and figuring things out within minutes. Just nature doing its thing.

Hard not to appreciate that kind of resilience.

The Cold Plunge is not just a trend. It is a form of hormesis, which means stress in the right dose that helps your body adapt, recover, and get stronger.

That stress activates your longevity switches. Basically, what does not kill you makes you stronger.

When you step into the cold, your blood vessels tighten, which can help calm inflammation.

It may feel uncomfortable at first, but that short burst of cold teaches your body how to adapt and bounce back. It is a natural reset that can make you feel alive.

✔️ Boosts circulation and recovery
✔️ Supports brain clarity, energy, and overall healing

It needs the right environment to heal.

Looking for a simple way to support your hormones and overall energy? Low testosterone could be part of the problem.

It doesn’t just affect muscle. You might notice low motivation, fatigue that doesn’t improve with rest, increased body fat, decreased strength, brain fog, or low mood.

Testosterone therapy can help you feel more like yourself again. It supports energy, strength, focus, and even body composition, helping you perform better in your day-to-day life.

Hormones are powerful and deserve guidance, not guesswork.

Have you considered red light therapy to support your energy and recovery?
