The science of brain optimisation is no longer just for elite athletes or Silicon Valley entrepreneurs. From Gary Brecka’s gene-based health strategies to Andrew Huberman’s neuroscience-backed routines, and even insights from Peter Attia and Bryan Johnson, there is one thing they all agree on: you can improve the way your brain works by understanding your biology.

In Functional Medicine, we call this personalised, systems-based care. Rather than guessing or relying on generic advice, we use real data to identify what your brain needs to function at its best. Whether your goal is to sharpen focus, improve memory, reduce anxiety, or slow cognitive decline, the tools exist. You just need to use them the right way.

What is Brain Biohacking?

Brain biohacking means using science-backed strategies to improve your cognitive function, mental clarity, and emotional regulation. It includes everything from nutrition and light exposure to breathing exercises, supplements, and sleep routines. It is not about quick fixes. It is about applying what we know from biology and neuroscience in a way that supports your specific needs.

Where Gary Brecka and Andrew Huberman Agree

Although they come from different fields, Gary Brecka and Andrew Huberman share a lot of common ground. Brecka works with gene expression, oxygen use, and nutrient protocols. Huberman studies how the brain responds to light, movement, stress, and habit formation. Here is where their approaches overlap:

They both believe that mental health, energy, and performance are driven by measurable processes in the body. Functional Medicine agrees. We assess neurotransmitters, hormone balance, gut health, inflammation, and more to understand what is causing symptoms like brain fog, fatigue, or mood swings.

They also highlight the importance of oxygen use and mitochondrial health. The Gary Brecka protocol uses targeted supplementation to boost energy production and reduce cellular stress. Huberman recommends daily light exposure, cold therapy, and breathwork to improve mitochondrial function and brain resilience.

In Functional Medicine, we apply these principles using tools like CoQ10, NAD+ support, and breath training tailored to your personal biology.

Both also stress the impact of chronic stress on brain performance. Huberman explains how cortisol dysregulation can impair focus and emotional regulation. Brecka’s testing shows how prolonged stress increases inflammation and accelerates cognitive decline. We address this by testing your cortisol rhythm, supporting your nervous system, and using adaptogens, sleep support, and personalised lifestyle changes to rebalance the brain and body.

How Functional Medicine Brings it All Together

Functional Medicine ties all these insights into a cohesive, personalised strategy. Using your longevity blueprint, we test and track key markers, then design a plan based on your real data. We look at nutrient status, hormone levels, detox function, blood sugar regulation, and your gut-brain connection. This helps us identify what is disrupting your mental performance and how to improve it.

For example, if your blood sugar is unstable, you may experience irritability and brain fog. If your thyroid hormones are low, your memory and mood may suffer. If you are deficient in B vitamins or magnesium, your stress response and sleep will be affected. We do not guess. We measure and intervene where it counts.

Peter Attia, Bryan Johnson, and the Biohacking Spectrum

Peter Attia is focused on healthspan, encouraging regular cognitive assessments, cardio fitness, and strength as protective tools against brain aging. Bryan Johnson takes a more aggressive approach, tracking dozens of biomarkers and following a strict supplement and lifestyle regimen. While their methods differ, both believe in the power of data and targeted change.

At Evergreen Doctors, we offer a middle ground. You do not have to take 100 supplements a day like Bryan Johnson, but we will help you find out what your body is missing and how to correct it. You will get a practical, science-based plan that fits your life and goals.

Brain Biohacks You Can Start Today

Here are a few simple, effective strategies that Brecka, Huberman, and Functional Medicine practitioners all support.

Get sunlight within 30 minutes of waking. This helps regulate your circadian rhythm and supports dopamine production.
Practice nasal breathing or structured breathwork to improve focus and reduce stress.
Consider methylated B vitamins if you have MTHFR or other gene variants that affect methylation.
Keep your blood sugar stable by reducing processed carbs and focusing on protein and fibre.
Add adaptogens like ashwagandha or rhodiola to your routine if you are under chronic stress.
Support sleep with consistent sleep-wake times, a cool dark room, and a wind-down routine.

Why Personalisation Matters Most

You are not Andrew Huberman or Gary Brecka. You are you. Your genes, stress levels, nutrient needs, and lifestyle are unique. What works for one person may not work for another.

That is why Functional Medicine is such a powerful tool. It lets us apply cutting-edge research to your real life, in a way that is sustainable and effective. We help you understand what your brain needs and guide you toward choices that make a difference.
