Gary Brecka Says Your Genes Hold the Key to Detox – Here’s What That Means for Liver Health and Mould Recovery
You can eat clean, take all the right supplements, even try to detox — but if your genes aren’t doing their part, you might still feel stuck. That’s the message from human biologist and wellness expert Gary Brecka, who’s become known for helping people understand how their genetics impact everything from energy to detoxification.
And when it comes to mould illness and liver health, this couldn’t be more important.
In this post, we’ll explore what Gary Brecka says about genetics and detox, how your liver fits into the puzzle, and how mould exposure could be overwhelming your system — unless you work with your genes, not against them.
The Gary Brecka Philosophy: Test, Don’t Guess
Gary Brecka's approach to health is simple but powerful: get data. His philosophy is built around the idea that we can’t optimise what we don’t measure — especially when it comes to the way our body handles toxins.
According to Brecka, one of the biggest missing pieces in mainstream medicine is the role of methylation genes — particularly MTHFR, COMT, CBS, and others involved in liver detox and inflammation.
If you’ve been exposed to mould, understanding these genes could be the key to finally feeling better.
Your Liver: The Unsung Hero of Detox
The liver is your body’s primary detox organ, and it works in two main phases:
Phase I uses enzymes to process toxins (e.g. from mould, alcohol, chemicals).
Phase II makes those toxins water-soluble so they can be excreted via bile or urine.
But here’s the kicker: both phases rely on nutrients and genetic pathways to function properly. If your genes mean you process toxins slowly, or you can’t produce enough glutathione (your body’s main antioxidant), then exposure to something like toxic mould can hit harder and linger longer.
Genes That Matter for Mould & Liver Health
Here are some of the key genes Gary Brecka often talks about — and how they relate to mould detox and liver function:
MTHFR – Needed for methylation and liver phase II detox. Mutations can impair B vitamin metabolism and toxin clearance.
COMT – Affects the breakdown of stress hormones and estrogens, which can accumulate when the liver is overloaded.
CBS – Linked to sulphur processing and ammonia detox. Imbalances here can worsen reactions to sulphur-rich supplements like glutathione or NAC.
GST (Glutathione S-transferase) – Involved in making and recycling glutathione, which binds and removes mould mycotoxins.
Knowing your status in these genes can shape everything — from the supplements you take to the pace at which you detox.
The Mould Connection: Why Some People Don’t Bounce Back
Mould exposure creates a toxic load — particularly from mycotoxins like gliotoxin, ochratoxin A, and satratoxin. These toxins place a huge burden on the liver and immune system.
So why do some people recover with basic interventions… while others spiral into chronic fatigue, brain fog, anxiety, and hormone issues?
It often comes down to this:
“If your detox genes are compromised and you don’t support your liver properly, even small amounts of mould can push you over the edge.”
This is why testing your genetics can be a game-changer.
What You Can Do: Get to Know Your Genetics
You don’t need a specialist referral or fancy clinic to get started.
One of the most accessible options in Australia is the i-screen MyDNA Comprehensive Health Report — an at-home cheek swab test that helps you understand how your genes influence:
Liver detox function
Vitamin and nutrient metabolism
Methylation pathways (e.g. MTHFR, COMT)
Inflammation and oxidative stress
Fitness, sleep, and diet compatibility

This is the kind of foundational data Gary Brecka uses with his clients — and it’s now available without needing to leave your home.
Final Thoughts: Leverage What You Can Control
Mould exposure might be outside your control — but how your body responds doesn’t have to be.
With the right information (and the right test), you can support your liver, reduce your toxic load, and give your body the tools it needs to heal. Like Gary Brecka says: your genes don’t doom you — they inform you.
