Heavy Metals and Your Health
Before I began mineral testing, I didn't realise how big a part heavy metals can play in people's health.
Whether we realise it or not, heavy metals are in our environment, and in modern life they're hard to avoid completely. Some exposures date back decades, lingering in soil and water. Others come through the air we breathe as a result of industry.
The good news is that once we know what your body is holding on to, there's a great deal we can do about it.
How Heavy Metals Affect the Body
Heavy metals can interfere with how your body uses its essential vitamins and minerals.
They can compete for the same sites in vital organs such as the brain, liver, kidneys and lungs. When a metal takes the place of a mineral your body needs, the processes that depend on that mineral can start to falter.
The body also has to put these metals somewhere. It tends to store them in tissues such as organs, bone and fat. Over time, that can contribute to feeling sluggish, heavy and inflamed.
The Metals I See Most Often
On Oligoscan and hair mineral analysis, the metals I see most commonly are:
aluminium - cookware, foil, antiperspirants, antacids; may be linked to brain fog, poor concentration, memory lapses
mercury - large fish, dental fillings; can affect nervous system, low mood, irritability, tremors
cadmium - cigarette smoke, industrial exposures, contaminated soil; can compete with zinc and affect kidneys and bones, fatigue
lead - old paint, pipes, soil; can settle in bones and interfere with iron, calcium and nerve function, and may be linked to headaches, joint pain and abdominal discomfort
copper - an essential mineral but can become a problem in excess; can affect hormones, anxiety and sleep
These symptoms are not specific to heavy metals, which is why testing and a full health picture matter more than guessing.
Exposure risk may be higher for people who live in older homes, near airport flight paths, or close to farmland or mining.
Signs a Heavy Metal Burden May Be Involved
I start to suspect heavy metals when I see:
ongoing inflammation or metabolic issues
high levels of anxiety
neurological or cognitive concerns, such as brain fog or poor memory
pain and nerve symptoms
mast cell activation syndrome (MCAS)
Heavy metals are rarely the whole story. But they can add significantly to the body's total burden and influence many different health conditions.
One adult client of mine had chronic nerve twitching in their forehead. Their mineral test showed high aluminium. Once we identified and removed their sources of aluminium, the twitching settled.
Why Aggressive Detox Can Backfire
This is where I see things differently from a lot of popular advice.
Detox kits and aggressive chelation can come with complications. When metals are pulled out of storage and back into the bloodstream, the body needs open pathways to eliminate them. Without those, metals can simply redistribute to other tissues and drive more inflammation.
So before any detox, I want to know whether your body has the capacity and reserves to cope with it.
Often, the first step is actually replenishing, rather than removing.
A Safer, Gentler Approach
The way I approach heavy metals is gradual and layered.
First, reduce exposure. If we know where aluminium, cadmium or other metals are coming from, we can start there.
Then, replenish. Testing shows what's in excess and what's deficient. Restoring essential nutrients builds the body's protective capacity. Selenium, magnesium, B vitamins, vitamin C and other antioxidants are very useful, along with liver-supportive nutrients and herbs such as NAC and milk thistle. Selenium, for example, helps the body manage mercury and cadmium.
Open the exit doors. The gut needs to be working well, bile needs to be flowing, and the liver needs capacity. Nourishing food, movement and good sleep all support this.
Pace the process. I build structure around how quickly detoxification happens, so the body is never pushed faster than it can cope.
Stress matters here too. When we're highly stressed, our ability to detoxify drops, and the body holds on to more. Calming the nervous system is part of the treatment.
Three First Steps
If you suspect heavy metals may be affecting your health, here's where I'd begin:
Get a blood test to check your vitamins, minerals, liver and kidney health, as these all influence how your body handles metals.
Do both an Oligoscan and a hair mineral analysis. Together, they show whether your body is storing metals or eliminating them, which is much harder to tell from one test alone.
Have your results interpreted by a qualified, experienced practitioner who can look at you as an individual and the factors that may be contributing to your exposure.
Please speak to a qualified professional before trying any chelation or detox protocol yourself.
When to See Your GP
Please see your doctor if you've had a known exposure, such as through your work, renovating an older home, or living near a contaminated site. Your GP can arrange blood testing for metals such as lead and mercury.
This is especially important for children and anyone who is pregnant or breastfeeding. Detox protocols aren't suitable during pregnancy or breastfeeding, as mobilising stored metals can affect the baby.
Please also seek medical care promptly for sudden confusion, severe abdominal pain, numbness or weakness.
Letting the Body Lighten It’s Load
Heavy metals can sound frightening, but they don't need to be.
With careful testing and a patient, well-paced approach, the body is remarkably capable of rebalancing and letting go of what it no longer needs.
