Copper Overload, Glucose, Malabsorption and Heavy Metals
🧪 Copper Overload – In Simple Terms
Copper overload happens when there is too much copper in the body and not enough zinc or ceruloplasmin (a protein that helps regulate copper). Copper is essential, but too much becomes toxic and causes an imbalance in mood, energy, and methylation.
⚖️ What Copper Normally Does:
-
Helps with iron metabolism
-
Supports the nervous system
-
Needed for enzyme function and brain health
🚨 Signs of Copper Overload:
Mental/Emotional |
Physical |
Anxiety or irritability 😠 |
Fatigue 🛌 |
Racing thoughts 💭 |
Headaches or migraines 🤕 |
Mood swings / PMS 🎭 |
Skin issues (acne, eczema) 🧖♀️ |
Depression/feeling overwhelmed 😞 |
Poor immune function 🛡️ |
High sensitivity to smells/sounds 🔊 |
Histamine intolerance 🤧 |
🧠 How It Affects Methylation:
-
Copper affects the DAO and MAO enzymes → messes with neurotransmitters like dopamine, norepinephrine, and histamine.
-
Often linked to undermethylation → high histamine levels
-
High copper can block zinc, which is needed for proper methylation
🧬 Genetic Links:
-
Low ceruloplasmin (due to stress, estrogen, or genetics) means copper isn’t bound properly.
-
Women on birth control or estrogen therapy are more at risk.
🛠️ Supportive Approaches:
✅ Increase:
-
Zinc (balances copper)
-
Vitamin C (helps detox copper)
-
B6 and molybdenum (support enzymes that use copper)
-
High-protein diet with sulfur-rich foods (eggs, garlic, onions)
🚫 Avoid:
-
Copper pipes, cookware, IUDs, multivitamins with copper
-
Estrogen-containing medications or birth control (if advised)
🧠 Copper & ADHD
-
High salivary copper linked to ADHD
A U.S. adolescent study found those with the highest quartile of salivary copper had a ~4× increased risk of ADHD (and up to 8.4× for combined subtype ADHD-C) compared to the lowest quartile. This supports earlier findings of elevated copper in urine and hair samples of ADHD cases reddit.com+12link.springer.com+12pubmed.ncbi.nlm.nih.gov+12. -
Elemental cycle disruptions in ADHD
Analysis of tooth biomarkers revealed that ADHD is associated with disrupted metal metabolism cycles, including copper. This dysregulation could impair antioxidant defences and promote dopamine oxidation, potentially harming dopaminergic neurons pmc.ncbi.nlm.nih.gov+1link.springer.com+1.
🔬 Copper & Autism Spectrum Disorder (ASD)
-
Hair and serum copper levels in ASD
A 29-study meta-analysis showed hair copper levels were LOWER in ASD children vs. controls, while blood levels showed no significant difference pubmed.ncbi.nlm.nih.gov+1pubmed.ncbi.nlm.nih.gov+1. -
Widespread review of metals in ASD
A broader review found elevated copper levels in ~15–30% of ASD children across multiple regions. These increases often correlated with more severe symptoms and were accompanied by low zinc/copper ratios, researchgate.net+14pmc.ncbi.nlm.nih.gov+14sciencedirect.com+14. -
Hair sample comparisons
A case-control study in Saudi Arabia revealed higher levels of toxic metals (e.g., lead, mercury) and lower essential minerals (like copper) in ASD vs. controls reddit.com+7pubmed.ncbi.nlm.nih.gov+7link.springer.com+7.
🌍 Prenatal Metal Exposure & Neurodevelopment
-
Norwegian pregnancy cohort study linked maternal copper (and other metals) in the non-linear range with childhood diagnoses of ASD and ADHD. Both high and low levels carry risk, highlighting that balanced copper levels are vital during neurodevelopment.
✅ Summary
-
ADHD: Elevated copper markers (saliva, teeth) linked to higher ADHD risk—possibly via oxidative stress and dopamine disruption.
-
ASD: Mixed findings—hair tests often show lower copper, while blood/serum may show higher levels or altered copper/zinc balance.
-
Balanced copper is key—prenatal exposure (too high or too low) may contribute to neurodevelopmental disorders.
👩🔬 For Researchers & Practitioners
-
Copper’s role is complex and context-dependent: tissue type (blood, hair, saliva), measurement timing (prenatal vs. childhood), and co-existing elements (zinc, lead, manganese).
-
A holistic mineral panel, including zinc, selenium, lead, mercury, alongside copper, offers a better picture than single measurements.

When the body cannot effectively get rid of copper in the body and it builds up, you get conditions like Wilson Disease and Menkes Disease.
🍬 Glucose Dyscontrol
Glucose dyscontrol means your body has trouble keeping your blood sugar levels steady. This includes high blood sugar (hyperglycemia), low blood sugar (hypoglycemia), or rapid swings between the two.
It’s often a root cause of fatigue, mood swings, weight gain, and inflammation.
⚖️ What Normally Happens
When you eat:
- Your food turns into glucose (sugar).
- The hormone insulin helps move glucose into your cells for energy.
- Any extra glucose is stored for later use.
If the system breaks down, blood sugar becomes unstable.
⚠️ Signs of Glucose Dyscontrol
Too High (Hyperglycemia) |
Too Low (Hypoglycemia) |
Fatigue after meals 😴 |
Shaky or dizzy before meals 😵 |
Cravings for sweets 🍰 |
Sudden hunger or irritability 😡 |
Brain fog 🧠 |
Sweating or heart racing 💓 |
Belly fat gain ⚖️ |
Headaches or lightheadedness 🤕 |
Frequent urination 🚽 |
Anxiety or panic attacks 😰 |
🧬 Methylation & Glucose Control – The Connection
Methylation affects insulin sensitivity, inflammation, and mitochondrial energy. When glucose is poorly regulated, it can:
- Stress mitochondria, lowering energy
- Increase oxidative stress and inflammation
- Lead to methylation slowdown or SAMe depletion
- Affect neurotransmitters like dopamine, serotonin, and GABA
Genes involved: TCF7L2, IRS1, SLC2A4 (GLUT4), MTHFR, COMT
🛠️ Support for Glucose Balance
✅ Focus On:
- High-fibre, whole-foods diet (low in sugar)
- Protein + healthy fats at each meal
- Magnesium and chromium (support insulin)
- B vitamins, especially B1, B6, and biotin
- Exercise (even light walking after meals)
- Stable meal timing (avoid skipping meals)
🚫 Avoid:
- Refined sugars, white flour, soda, and processed foods
- Overuse of caffeine (spikes blood sugar)
- Eating large amounts of carbs alone
Malabsorption
Heavy Metals
“You might love Metallica, but your liver doesn’t love mercury!”
⚙️ Heavy Metals & Methylation
Heavy metals like lead, mercury, arsenic, aluminium, and cadmium are toxic elements that can disrupt methylation, overload detox systems, and harm the brain, liver, and immune system.
🧬 How Heavy Metals Affect Methylation
Impact |
What Happens |
❌ Inhibit methylation enzymes |
Metals like mercury and lead block enzymes like MTHFR, BHMT, and CBS |
🧪 Reduce glutathione |
Glutathione is needed for detox, and methylation helps make it |
🧠 Disrupt neurotransmitter balance |
Affect dopamine, serotonin, and GABA → mood, focus, and sleep problems |
💥 Causes oxidative stress |
Metals increase free radicals, which damage cells and slow methylation |
⚖️ Methylation uses up resources |
Detoxing metals consumes methyl donors (SAMe) and B vitamins |
⚠️ Signs You Might Be Affected by Heavy Metals
- Chronic fatigue or brain fog 😵💫
- Mood swings, anxiety, or depression 😔
- Poor memory and concentration 🧠
- Skin rashes or unusual allergies 🤧
- Slow detox (chemical sensitivity, headaches)
- Sensitive to supplements or meds
- Diagnosed with MTHFR or GST gene variants
🛠️ Supporting Detox & Methylation Together
Support Strategy |
Why It Helps |
Methyl donors: B12, methylfolate, TMG |
Fuel methylation to support detox pathways |
Glutathione boosters: NAC, vitamin C, selenium |
Helps neutralise and carry out heavy metals |
Binders: Chlorella, activated charcoal |
Help “trap” metals for safe removal |
Zinc |
Competes with toxic metals like cadmium |
Sweating: Sauna, exercise |
Promotes the excretion of metals through the skin |
⛔ Be Cautious:
- Never do a heavy metal detox without supporting methylation first.
- Aggressive detox (like chelation) can stir up metals and worsen symptoms if your methylation and glutathione systems are weak.
Statement: Never do a heavy metal detox without supporting methylation first:
✅ How to Support Methylation First
Here’s a step-by-step foundation to prepare your body:
1. Assess Nutrient Status
Make sure your body has the core nutrients that fuel methylation:
Nutrient |
Best Forms |
B12 |
Methylcobalamin or Hydroxycobalamin (start low) |
Folate |
Methylfolate (5-MTHF) — NOT folic acid |
B6 |
P5P (active B6) |
B2 |
Riboflavin-5-phosphate |
B3 |
Niacin or Niacinamide (can help “mop up” excess methyl groups) |
Magnesium |
Glycinate, malate, or threonate |
Zinc |
Glycinate or picolinate |
Trimethylglycine (TMG) or Choline |
Secondary methyl donors |
2. Test (if possible)
Get a sense of your methylation status via:
- Organic Acids Test (OAT)
- Homocysteine blood level (ideal = ~6–8 µmol/L)
- Genetic testing for MTHFR, COMT, CBS, etc.
3. Support Detox Pathways Gently
Methylation is part of detox, but it also relies on glutathione and liver function:
- N-acetyl cysteine (NAC) or liposomal glutathione
- Milk thistle, dandelion root, and burdock to support the liver
- Vitamin C and selenium to reduce oxidative stress
4. Balance Before Boosting
If you have symptoms of overmethylation (anxiety, insomnia, irritability), start slowly with methyl donors and include niacin to buffer.
If you’re undermethylated (fatigue, depression, high histamine), you may need more B12/folate/zinc.
5. Start Low, Go Slow
Start with low-dose methylated B vitamins, and only add detox agents (e.g., binders, chelators, chlorella, EDTA, DMSA) once you’re tolerating methylation support well.
🚨 Summary:
Fuel methylation ➝ open detox channels ➝ THEN start metal detox.
Think of it like unclogging the drain before pouring dirty water in.
Statement: Aggressive detox (like chelation) can stir up metals and worsen symptoms if your methylation and glutathione systems are weak:
NOTE: Though the most effective form of getting rid of heavy metals is CHELATION, as it bonds well with certain elements, making it either easier to eliminate or be absorbed. Always consult your doctor first.
There are many other chelating medications, of which DMSA (oral), DMPS (transdermal and intravenous and TTFD (transdermal) are some. DMSA is very commonly used. (Amendment suggested by Dr Louise Lindenberg)
⚖️ Clarifying the Two Uses of “Chelated”
Term | What It Means | Safe for MTHFR? | Purpose |
---|---|---|---|
Chelated Minerals | Minerals (like zinc or magnesium) are bound to amino acids for better absorption | ✅ Yes – gentle, supportive | To nourish methylation pathways and fix deficiencies |
Chelation Therapy (Heavy Metal Detox) | The use of agents (like DMSA, EDTA, DMPS) to bind and pull out toxic metals | ⚠️ Only when methylation & glutathione are strong | To actively detox heavy metals like mercury, lead |
🧬 Why This Matters for MTHFR
-
People with MTHFR mutations often have impaired detox capacity and may not produce enough glutathione.
-
Jumping into aggressive chelation therapy before supporting methylation can:
-
Stir up mobilised metals into the bloodstream
-
Overwhelm detox pathways
-
Lead to symptoms like fatigue, anxiety, headaches, or neurological issues
-
✅ Recommended First Step:
Support your body with chelated minerals like:
-
Zinc glycinate – supports methylation, immunity, and balances copper
-
Magnesium malate/glycinate calms the nervous system
-
Selenium supports glutathione production
-
B vitamins (especially methylfolate + B12) – essential for methylation
🛑 Caution:
Chelation therapy (to remove heavy metals) should only be done when:
-
Methylation is supported
-
Gut, liver, and kidneys are functioning well
-
Glutathione is adequate
-
Supervised by a knowledgeable practitioner
In Short:
✅ Chelated minerals = nourishment
⚠️ Chelation therapy = extraction (and risky if you’re not ready)
Chelated mineral supplements are often recommended for people with MTHFR gene variants, especially those with reduced methylation capacity. Here’s why:
🧬 Why Chelated Minerals Help in MTHFR
Chelated Form |
What It Means |
Why It’s Better |
“Chelated” = “bound to an amino acid” |
Example: zinc glycinate, magnesium bisglycinate |
Easier to absorb, gentler on the stomach |
Highly bioavailable |
More likely to be absorbed even if gut or methylation is compromised |
Reduced need for high dosing |
Less reactive |
Fewer GI side effects like nausea or loose stool |
Safer for people with detox or histamine issues |
🧠 Key Chelated Minerals for MTHFR Support
Mineral |
Chelated Form |
Why It’s Important |
Zinc |
Zinc picolinate or glycinate |
Supports MTR, DAO, immune system, and balances copper |
Magnesium |
Magnesium glycinate or malate |
Supports ATP production, calms nerves, and helps sleep |
Selenium |
Selenomethionine |
Needed for glutathione, thyroid, and antioxidant defence |
Iron (if deficient) |
Iron bisglycinate |
Less harsh on digestion than ferrous sulfate |
Calcium |
Calcium citrate-malate |
Needed for muscle and nerve function, but balanced with magnesium |
🚫 Avoid Non-Chelated or Hard-to-Absorb Forms:
- Oxide forms (e.g. magnesium oxide) — poorly absorbed
- Sulfates and carbonates may cause GI upset
- High-dose non-chelated minerals may irritate the gut and compete with other nutrients
⚠️ Tips for Use:
- Always balance zinc with copper (especially if supplementing long-term)
- Use with a functional practitioner if you have detox, copper/zinc, or sulfur issues
Choose low-and-slow dosing with chelated forms to minimise reactivity.
