Anxiety might not be “in your head” — it could be in your genes.
That’s the eye-opening message from human biologist Gary Brecka, who’s on a mission to shift how we understand mental health, chronic disease, and aging.
Brecka, who spent two decades in the life insurance industry predicting when people would die, says the keys to longevity and health aren’t always found in your environment — but in your biology.
In a recent podcast conversation, Brecka revealed how overlooked gene mutations and nutrient deficiencies may explain stubborn symptoms like anxiety, ADHD, fatigue, insomnia, and more.
If you’ve ever felt like your health concerns don’t really respond to conventional treatments, or you feel “off” for reasons you can’t explain — this may change everything.

Why Anxiety Often Has No Obvious Trigger
Many people with anxiety struggle to explain why — there’s no major life event, no clear phobia or trauma they can point to. Brecka says that’s because the root cause is often internal, not external.
According to Brecka, the culprit in many cases is excess catecholamines — a class of neurotransmitters that includes adrenaline, dopamine, and norepinephrine — linked to your body’s stress response.
“Anxiety is a physiological overreaction to a perceived threat — even when there isn’t one,” says Brecka. “People are trying to pin it on their environment, but it’s happening inside their body.”
The Genetic Link to Anxiety and Focus Disorders
One gene in particular — the COMT gene (short for catechol-O-methyltransferase) — plays a major role in how quickly your body clears those stress chemicals.
A variation in this gene may result in a “slow metabolizer” phenotype, meaning adrenaline and dopamine linger far too long, creating a sense of unease, overthinking, and hyper-alertness.
“Ever lay down at night physically tired but mentally buzzing? That’s a signature sign,” says Brecka. “They’re not attention-deficit — they’re attention-overload.”
Other common signs include:
- Difficulties winding down after stress
- Racing thoughts or catastrophic thinking
- Feeling anxious without a clear reason
- Unexplained mood swings or increased sensitivity to stress
The Role of Methylation in Mental and Physical Health
These symptoms, Brecka says, can often be traced back to poor methylation — a biological process essential for producing neurotransmitters, detoxifying the body, and regulating inflammation.
Methylation depends on access to vital nutrients like B12 (specifically methylcobalamin), methylfolate, and other B vitamins. Without them, the process gets disrupted.
“Disease isn’t always something that happens to us. Sometimes it’s just the body missing a key raw material,” says Brecka.
This concept isn’t limited to mental health — poor methylation is also tied to conditions like:
- Chronic fatigue
- Depression
- Immune dysfunction
- Gut issues and inflammation
- Sleep disorders
Why Standard Blood Tests May Miss the Bigger Picture
Brecka emphasizes the value of going beyond conventional lab panels. While standard tests can offer a snapshot, they often miss deeper issues related to gene expression and nutrient conversion.
The solution? A one-time genetic methylation test.
“It uncovers exactly what nutrients your body cannot convert into usable forms,” he explains. “Once we know that, we can directly supplement with the active forms.”
The top five genes Brecka recommends testing for:
- MTHFR
- MTR
- MTRR
- AHCY
- COMT
The “Palm Tree Analogy”: What Plants Can Teach Us About Healing
Drawing from his background in biology, Brecka shares a powerful analogy: “If you saw a rotting palm leaf, a good arborist wouldn’t treat the leaf — they’d test the soil.”
Similarly, fixing symptoms isn’t about masking them — it’s about finding deficiencies and restoring balance at the foundation.
“Most of us are supplementing blind,” he warns. “We throw in vitamin C, Resveratrol, CoQ10 — but overlook what we actually need.”
A Data-Driven Approach: Inside Brecka’s Health System
Brecka’s wellness company now runs over 20,000 genetic tests a month and gathers real-time biomarker data on everything from blood chemistry to hormones.
With that data, the team maps out how small shifts — like adding methylfolate — can normalize blood pressure, improve sleep, or resolve fatigue without prescription medication.
“I’ve seen people go from symptom-ridden to thriving in just weeks — all by putting back what’s missing,” he says.
Simple Tests Everyone Should Start With
According to Brecka, the following health markers are foundational for anyone seeking peak performance and long-term wellness:
1. Glycemic Profile
Includes fasting glucose, insulin, and hemoglobin A1c. Elevated levels signal prediabetes or metabolic dysfunction, which impacts everything from brain fog to inflammation and hormone imbalance.
2. Hormone Panel
Check levels of testosterone, free testosterone, SHBG, and DHEA. Hormonal imbalances often stem from nutrient deficiencies, not dysfunction.
3. Nutrient Deficiencies
Test for vitamin D3, B12 (specifically methylcobalamin), magnesium, and potassium. These are essential for energy, mood, and longevity.
4. Genetic Methylation Test
Done once in your lifetime, this test helps you understand what your body can’t convert — and how to support it with targeted supplementation.
Five Free Habits That Can Change Your Life
Want to reduce anxiety and get more energy — without spending a fortune? Brecka recommends starting with these habits:
1. Start Your Day with Mineralized Water
Add a pinch of Celtic sea salt or Baja Gold sea salt to your morning water. It replenishes trace minerals essential for nerve function, stress adaptation, and hydration.
2. Ground Yourself Daily
Walk barefoot on grass, dirt, or sand for at least 10 minutes. “It repolarizes your cells and reduces inflammation,” says Brecka. It may even improve sleep and mood.
3. Practice Breathwork
Do three rounds of 30 deep breaths with an extended breath hold. This boosts oxygen delivery, lowers stress, and gives you a consistent morning anchor.
4. Get Morning Sunlight
Expose your eyes and skin to early sunlight within 30 minutes of waking. It anchors circadian rhythm, improves sleep quality, and naturally boosts mood.
5. Train Resistance + Track Your Labs
Strength training protects muscle mass and hormone levels. Pair it with routine lab tests to guide your nutrition and lifestyle with real data.
The Bottom Line
If you’re facing nagging health concerns, or feel like something’s “off” — even without a diagnosis — consider that the root may be inside your cells, not outside your life.
“We have more data on our businesses than our bodies,” Brecka says. “That has to change.”
The real power lies in understanding your body, identifying deficiencies, and supporting your biology — not blindly chasing diagnoses or supplements.
Because feeling normal again might only be one missing raw material away.
