Is Toxicity Holding You Back? Understanding Heavy Metal Toxicity and How to Take Back Your Health
Imagine waking up every morning feeling clear, calm, and full of energy - no unexplained fatigue, no dull headaches, no brain fog.
For many high-performing, health-conscious individuals, the opposite is often true. Despite eating well, exercising, and prioritising sleep, something still feels off. Could it be your toxic load?
At Expand Health, we’re seeing more and more clients struggling with hidden toxicity, especially heavy metal accumulation, that silently disrupts their energy, focus, hormones, and even immunity. The truth is: detoxification isn’t a trend. It’s a vital part of maintaining cellular health and longevity in the modern world.
Let’s explore why.
The invisible burden: What is heavy metal toxicity?
Heavy metal toxicity occurs when the body accumulates higher-than-safe levels of certain metals like lead, mercury, arsenic, aluminium, cadmium, and nickel. These metals are naturally occurring in our environment, but chronic, low-level exposure through water, air, cosmetics, dental materials, cookware, pollution, and even food can cause them to build up in tissues over time.
Once in the body, heavy metals interfere with cellular processes, impair mitochondrial function, damage DNA, and create systemic inflammation, all of which are linked to fatigue, cognitive dysfunction, hormone imbalance, and increased risk of chronic disease.
How common is it?
According to the World Health Organization, lead exposure alone accounts for 900,000 deaths globally each year, largely due to cardiovascular and kidney complications.¹
A CDC report found that over 50% of adults tested in urban areas had detectable levels of multiple toxic metals.²
Yet most people with heavy metal toxicity don’t know they have it - until symptoms worsen or they undergo specific testing.
Symptoms of heavy metal overload
Because heavy metal accumulation often happens slowly, it can mimic or exacerbate other health issues. Symptoms may include:
• Chronic fatigue or burnout
• Brain fog, memory issues, poor concentration
• Headaches or migraines
• Mood swings, anxiety, or depression
• Hormonal imbalances
• Digestive issues or poor detox capacity
• Skin issues, like eczema or rashes
• Sleep disturbances
• Recurring infections or suppressed immunity
How we test for heavy metal toxicity at Expand Health
At Expand Health, we use spectrophotometry testing - a non-invasive, clinically validated tool that measures mineral status and detects heavy metal levels in your tissues in real-time. Unlike traditional blood or urine tests that may reflect only recent exposure, using this test reveals long-term accumulation and mineral imbalances that can point to impaired detox function.
This allows us to create targeted, personalised action plans, guided by:
- Dr Fred van der Riet, our Integrative Medical Doctor, who helps interpret your test results in context with your full health history and symptoms.
- Maryke Gallagher, our Detox Nutrition Specialist, who creates dietary and supplemental protocols to support your body’s natural detox pathways - liver, kidneys, gut, lymph, and skin - safely and effectively.
Why detoxification matters for longevity:
You can eat the best food, breathe clean air, and take all the right supplements, but if your body is burdened with toxins it can’t excrete, you may never feel fully well.
Research shows:
• Heavy metals like cadmium and lead are associated with accelerated ageing and shortened telomeres.³
• Mercury exposure contributes to neurodegeneration and mitochondrial dysfunction.⁴
• Arsenic disrupts metabolic function and increases risk of cardiovascular disease and cancer.⁵
Supporting detoxification isn’t about "cleansing" in a trendy way - it’s about giving your body the tools to do what it already knows how to do.
How to reduce your toxic load (and support your detox pathways)
Detox is not a one-size-fits-all approach. At Expand Health, we focus on custom protocols based on your body's current needs, your health history and your unique genetic composition, but here are some general longevity-supportive detoxification steps:
1. Eat a detox-supportive diet (if tolerated)
Include:
• Cruciferous vegetables (broccoli, cauliflower, kale)
• Cilantro, parsley and kelp (natural metal chelators)
• Sulphur-rich foods like garlic and onions
• Antioxidant-rich berries and green tea
2. Support liver and kidney function
• Stay hydrated with mineral-rich water
• Limit alcohol and processed foods
• Consider targeted supplementation under professional guidance (e.g., glutathione, NAC, alpha-lipoic acid)
3. Reduce exposure
• Use clean, toxin-free skincare and household products
• Choose glass or stainless steel over aluminium or plastic
• Filter your drinking water
• Avoid high-mercury fish products
4. Integrate detox-enhancing therapies
At Expand Health, we offer supportive therapies like:
• Ozone Sauna (HOCATT): boosts circulation and lymphatic detox
• IV Glutathione: a master antioxidant for liver support
• PEMF Therapy: improves cellular oxygenation and detox pathways
