Heavy Metal Toxicity

Many people have become aware of the mercury toxicity problem. But it would be a mistake to think that metal poisoning is unique to this particular toxin. Consider: silver colloid is an antiseptic and has been used since ancient times to inhibit bacteria in drinking water. If it poisons germs, it will poison you. I have written elsewhere in the site that iron forms the most destructive free-radical of all (“hot iron”), very damaging to life.

The fact is that all metals are toxic and our bodies require special transport and handling mechanisms to keep them from harming us. This applies just as much as essential minerals, like iron, zinc and chromium, as it does to non-essential metals and metalloids, like cadmium and arsenical compounds.

Heavy metals and cancer

Metals can directly and indirectly damage DNA and that means an increased risk of cancer (we call this genotoxicity). There are also possibly non-genotoxic pathways, due to irritation or immuno-toxicity. Sure enough, a number of metals are known to be carcinogenic. These are:

  • arsenic and arsenic compounds,
  • beryllium and beryllium compounds,
  • cadmium and cadmium compounds,
  • nickel compounds and
  • hexavalent chromium (remember the movie “Erin Brockovich”?).

The usual target is the lung, though arsenic has a unique association with skin cancers that has been recognized for many years.

It is a fact that metal implants in the body (as, for example, in bone pinning or plates) may be associated with adjacent cancers, caused by irritation of the tissues. The late Patrick Stortebecker at the Karolinska Institute in Stockholm also pointed out the frequency with which cancer of the jaw was found in association with metal amalgam fillings. That is disturbing, since this particular kind of “prosthetic” tends to be very long term and very common indeed.

A major development in dentistry is the titanium implant, to replace lost teeth. But it is an act of faith to suppose that titanium is inert.

Other metals which cause damage

The presence of toxic metals in our systems is highly significant for they are capable of causing serious health problems through interfering with normal biological functioning. Although they can be found in high concentrations in the body, a number of these heavy metals (aluminum, beryllium, cadmium, lead and mercury) have no known biological function. Others (arsenic, copper, iron and nickel) are thought to be essential at low concentrations, but are toxic at high levels. Generally speaking, heavy metals disrupt metabolic function in two basic ways:

First, they accumulate and thereby disrupt function in vital organs and glands such as the heart, brain, kidneys, bone, liver, etc.

Second, they displace vital nutritional minerals from where they should be in the body to provide biological function. For example, enzymes are catalysts for virtually every biochemical reaction in all life-sustaining processes of metabolism. But instead of calcium being present in an enzyme reaction, lead or cadmium may be there in its place. Toxic metals can’t fulfill the same role as the nutritional minerals, thus their presence becomes critically disruptive to enzyme activity.

Because their impact is at such a foundational level, heavy metals can be causal factors in literally any health problem.

If your job or living circumstances expose you to heavy metals, you would do well to minimize or eliminate your exposure as much as possible. Be aware that there are many ways these toxins can be absorbed into your body–through foods and beverages, skin exposure, and via the air you breathe. So, whenever possible, wear gloves, use protective breathing apparatuses, and be sure to obtain fresh air ventilation.

Avoiding Heavy Metal Exposure is Impossible

Such preventative measures are worthwhile and important , but ultimately futile. The inescapable reality is that it is impossible in this day and age not to be exposed to heavy metals. It is only a matter of how much and how often.

So we need to get rid of this killer junk. How do we do it?

The answer is chelation. Chelation means, by definition, grasping and eliminating heavy metal poisons.

Stealth pathogens

Today we are seeing more and more cryptic lingering infections due to so-called “stealth pathogens”. In the 60s we used to talk of the “smouldering virus” but it is now abundantly clear that bacteria are also to blame and so the broader term is preferred. Notable are cytomegalovirus (CMV), Chlamydia pneumoniae, Epstein-Barr and Borrelia bugdorferi (Lyme disease). But there are others and probably plenty more waiting to be discovered.

A good doctor today, when confronted with any kind of chronic disease, must think of stealth pathogens. That in turn implies terrain problems. And terrain means pollution, possibly pesticides and chemicals, but more probably heavy metal overload.

It goes without saying that cleaning up the metallosis is more important than treating the pathogen or the disease, though this is alien to the modern drug-based medical canon!

Persistence in the environment

One of the problems with metals is their environmental persistence. Once mined and brought into the ecology, they last almost indefinitely.

Also, we face the usually-ignored problem of potentiation, which means two relatively small doses of two different substances may have a dramatically enhanced effect when present together. For instance it is not widely known that the presence of lead (which is everywhere) makes mercury 100 times more toxic.

We call these metal-metal interactions and they might be quite critical in the formation of cancers. Animal studies also indicate, for example, that calcium enhances lead toxicity in rats and cadmium increases the likelihood of cadmium-induced prostatic cancer.

Given these insights, the complacency of traditional dentists over the cocktail of metalloids they put in our mouths as “amalgam” is little short of scientific folly. In the US they call them silver fillings, in an effort to imply purity and divert from the fact they are an amalgam of several different metals, of which silver is only a small proportion of the whole.

Protection from other metals

But it also works the other way. The presence of a second metal may actually protect against toxicity. Thus, for instance, magnesium was shown in animal studies to prevent cadmium-induced testicular tumours and zinc blocks lung cancer caused by continued inhalation of cadmium. Both magnesium and manganese were effective at preventing tumours which otherwise formed at the site of nickel injections in rats.

In fact magnesium has been shown to have a wide variety of beneficial effects against metal carcinogenesis risk factors. Yet another reason why magnesium is one of the most vital and health-giving nutrients we have. Avoid deficiency at all costs.

We have known for decades that selenium is vitally protective against mercury and also has a powerful anti-cancer benefit. When the daily intake is 100 microgrammes or more (200 mcg. is better), the risk of cancer from all sources drops dramatically.

What can you do?

Apart from living in isolation on an organic farm, not much. And that’s only relative. Don’t be fooled that you would be safe in this environment; metals are in the air, as experience with strontium 90 and other radio-active atoms shows. Attempts to remove lead from our motor combustion engines is a good start. Better copper-based plumbing is also a right move.

But there is much pollution in the food chain. Lead dust is everywhere by the highways and in the dirt, left there from over a quarter of a century ago, when it was spewed by motor exhausts. Having an intelligent strategy to get rid of heavy metal poisons is critical to survival in the coming century and much wiser than wishing it wasn’t there or wanting to run away to some transient utopia.

Do all you can to reduce the load by all means.
But rely more on competitive inhibition: that means the presence of “good” metals to squeeze out the bad ones. Remember all metals are toxic. But in reasonable physiological doses zinc, magnesium and selenium are important protectives. Fill up the seats with good guys and the bad guys can’t enjoy the show.

You should be taking 200 mcg. daily of selenium, 20- 50 milligrams of zinc (citrate form is shown to be best absorbed) and 350 milligrams of magnesium, as the orotate, gluconate or amino-chelate. Watch out for diarrhoea from magnesium salts, otherwise you might actually suffer a loss of mineral intake.

These will tend to squeeze the bad guys.

Chelation

DMPS, DMSA, KELMER and EDTA Where the situation is serious, for example, lead or copper overload, I give IV ethyldiethylamine tetracetic acid (EDTA), in a series of infusions taking 3 hours or so each. The many benefits of this therapy can be read elsewhere on this site.

Unfortunately, this therapy is inadequate for mercury toxicity. There are three effective strategies for mercury, each with pros and cons:

6- 10 IV infusions of DMPS, 3 mgms per kg of body weight. These need skilled experience but done properly and at the correct dose I find have virtually no side-effects. The theoretical risk here is that DMPS crosses the blood-brain barrier and may carry mercury into neurological tissues, where it is most unwelcome. Side effects can be unpleasant and this seems the least advisable method.

Oral DMSA, 30 mgms per kg body weight. Duration depends on response but in the region of 6- 10 weeks. Side effects can be unpleasant but can be ameliorated by reducing the dose. Generally children tolerate DMSA much better than adults.

Oral chelation with magnesium succinate (*marketed as Kelmer), 60 mg per kg body weight. I am satisfied that this produces the same degree of mercury elimination as DMSA but without the unwanted side effects. It just takes longer, is all!

There is controversy over whether EDTA will remove mercury. For all sorts of scientific reasons, to do with valence and electrical charge, it shouldn’t work well. But Dr Gary Gordon claims is does: by actual urine and tissue testing, that it can been seen being excreted after his oral chelation regime (which admittedly includes a lot more than mere EDTA).

Self-administered therapy is not recommended. But chlorella is a great heavy metal attractor, is safe and plentiful. Lesser players are garlic and cilantro.

Finally, remember that once the source of contamination is removed, if you support your body with good de-tox and nutritional requirements, the heavy metals will gradually disappear from the tissues by slow attrition, a process termed leaching or, more exactly, depuration.

Chelation therapy is the most commonly used conventional treatment for lead and other toxic metal poisoning. It is an increasingly popular alternative therapy for the treatment of cardiovascular disease, particularly atherosclerosis, and other chronic degenerative conditions.

I have taken to combining it with IV antioxidants, especially brain-aid glutathione and call this intravenous anti-oxidant therapy. I believe it is the best anti-ageing intervention we have (I’m not counting diet as an intervention!)

HISTORY

The effectiveness of chelation in reducing arterial degeneration was discovered purely by accident. EDTA was first used in the 1940s to treat heavy-metal poisoning. When elderly patients being treated for chronic lead poisoning showed dramatic improvement after EDTA chelation therapy, scientists became interested in its broader use.

The use of EDTA to treat cardiovascular disease has generated scientific interest since the 1950s. Researchers in those days, however, lacked the noninvasive tools available today, such as Doppler and ultrasound, to evaluate changes in the arteries. Interest in the compound’s use waned in the 1960s when new surgical techniques were developed to unclog blocked arteries.

Furthermore the patent on EDTA expired, making it unprofitable for a drug company to sponsor research.

WHAT IT IS

Chelation therapy involves the intravenous infusion of EDTA (ethylene-diamine-tetra-acetic acid = 4 molecules of vinegar!!) to remove heavy metals from the body and to reverse atherosclerosis. EDTA is usually given as a slow intravenous solution over a period of four hours.

EDTA binds to metals and minerals, thereby helping the body get rid of these compounds. Practitioners no longer believe its beneficial effects are brought about by unclogging arteries (the so-called Roto-Rooter effect). This led I think to excessive and unjustifiable claims and resultant critical attacks. We now know about the nitric oxide mechanism and other ways by which it might bring substantial benefits (as it does). Chelation also works as a powerful antioxidant, which we know has anti-ageing, anti-cancer and anti-heart disease effects.

EDTA may also function as a calcium channel blocker, a category of conventional drugs called vasodilators that cause blood vessels to relax and widen. EDTA has also been shown to increase the concentration of other vasodilators.

EDTA’s ability to remove ions that cause harmful oxidation of fatty materials may also help maintain cellular health.

Chelation therapy generally requires 20 to 30 treatments at a cost of up to $140 (£100) per visit, or about $3-4,000 (£2500) per patient for the whole course. While this represents a substantial amount of money when paid out of pocket, it is a tiny fraction of the cost of conventional therapies, such as bypass surgery, used to reduce cardiovascular disease, and carries none of the risks a procedure such as that entails.

ORAL CHELATION

Dr Garry Gordon in particular is an advocate of oral chelation – powders and capsules. He has his critics, even among the ranks of holistically-oriented chelation doctors. But I believe he produces an abundance of reliable evidence of its safety and efficacy (5070 references) and I would be doing it now in my practice, if I still ran an office.

CARDIOVASCULAR DISEASE

Chelation therapy is widely used for the treatment of atherosclerosis and other chronic degenerative diseases involving the circulatory system. An estimated 500,000 people have undergone chelation therapy in the United States alone.

RESULTS FROM AROUND THE WORLD

A review of treatment results from 2,870 patients in Brazil found significant improvement in patients with heart disease or peripheral vascular disease who were treated with chelation therapy. Patients with heart disease were rated as showing “marked” improvement in 76.9 percent of cases and “good” improvement in 16.6 percent. Those with peripheral vascular disease showed a “marked” improvement in 91 percent of cases and “good” improvement in 7.6 percent.

In another study, the same researchers looked at patients with cerebrovascular disease and found 24 percent of the subjects showed “marked” improvement, and 30 percent showed “good” improvement.

A study from Switzerland showed that people who had had a course of chelation were 90% less likely to develop cancer!

WHO DOES IT

The American College of Advancement in Medicine (ACAM) has been granted approval by the Food and Drug Administration to study chelation therapy to treat peripheral vascular disease. The college provides a protocol for the use of chelation therapy and offers education and training in chelation therapy.

Chelation therapy may be legally practiced by a licensed medical or osteopathic physician. Look for a physician who has additional training and certification in the procedure. Approximately 160 physicians in the United States are certified by the American Board of Chelation Therapy, which requires physicians to undergo special training, pass a written exam, and give 1,000 administrations of chelation therapy before becoming a Diplomate (DIPL). Physicians who are in the process of completing their requirements for certification are called Diplomate Candidates, or D/C. Another ACAM designation is Fellow, which means that the physician has some training in chelation therapy but does not fulfill all the requirements to be a candidate for certification.

CAUTION: SIDE EFFECTS
Proponents of chelation therapy say its risks are similar to that of normal doses of aspirin and that early reports of side effects such as kidney toxicity were the result of doses that were too high. The American College of Advancement in Medicine provides recommendations for dose and rates of administration, as well as guidelines for dietary supplements with multivitamins and trace elements that should be taken during therapy.
