Chelation Therapy and Heart Disease: A Deep Dive into Potential Benefits
Chelation Therapy and Heart Disease. Cardiovascular disease remains one of the leading causes of mortality worldwide. With myriads of available treatment options, a less-known but intriguing approach has emerged: Chelation Therapy.
Rooted in its primary use for heavy metal poisoning, chelation for heart disease has garnered attention, thanks in part to studies like the TACT (Trial to Assess Chelation Therapy). This article delves into the potential benefits of chelation therapy for heart disease, anchoring our exploration in the findings of the TACT.
Understanding Chelation Therapy
Before we proceed, it’s essential to grasp what chelation therapy entails. At its core, chelation involves the administration of chelating agents that bind to metal ions in the body. This process facilitates the removal of these metals, initially used to treat heavy metal poisoning. The keyword here is ‘bind’: the chelating agents ‘grab’ these metals, allowing them to be safely excreted.
Research has explored the idea that chelation might also bind to calcium deposits in the arteries. The hypothesis? By reducing calcium-based plaque build-up, there’s potential to improve blood flow, addressing one of the core issues in heart disease.
The TACT (Trial to Assess Chelation Therapy)
The TACT study is arguably the most comprehensive exploration of chelation therapy’s role in heart disease done to date. Initiated in 2003, this study was designed to assess the safety and efficacy of EDTA (ethylene diamine tetra-acetic acid) chelation therapy in individuals with a history of myocardial infarction ( heart attacks ).
Promising Findings from TACT
Reduction in Adverse Cardiovascular Outcomes:
The TACT indicated that chelation therapy could lead to a modest reduction in cardiovascular events. The findings suggested that those receiving chelation therapy experienced fewer subsequent heart issues when compared to the placebo group.
Beneficial for Diabetes Patients:
One of the most notable revelations from the TACT was the pronounced benefit observed among patients with diabetes. The trial showed that diabetic participants had a 41% relative reduction in the risk of any cardiovascular event and a 43% reduction in the risk of death from any cause.
Safety:
An essential facet of the TACT was its rigorous monitoring for potential side effects. The findings affirmed the relative safety of chelation therapy when administered under appropriate medical supervision.
Supporting data from the TACT provides a foundation for understanding how chelation therapy could play a role in modern cardiology, especially in specific subsets of patients like those with diabetes.

TACT2 Study
TACT2 was a study that looked at how EDTA chelation treatment might help heart health, especially for people with diabetes. Here’s what they found:
Blood Sugar Levels Stayed Stable:
This treatment didn’t seem to change people’s blood sugar levels much. Whether they were on the treatment or a placebo (a fake treatment), their blood sugar levels stayed about the same. No surprise here, really, though.
Diabetes Medication Needs Didn’t Change Much:
Most people with diabetes still needed the same amount of diabetes medicine after the study, whether they had the real treatment or the placebo. Again no surprise.
Heart Benefits for Those with Diabetes:
This is where things get interesting! People with diabetes who got the real treatment had fewer major heart problems. They did 41% better than those on the placebo.
There were also fewer other heart issues in the treated group.
In simple terms, TACT2 found that this EDTA chelation treatment might be a pretty good option for the hearts of people with diabetes.
The Mechanism: How Does Chelation Impact Heart Disease?
The underlying mechanism of how chelation affects heart disease is multifaceted. One dominant theory aligns with the chelation’s inherent action of binding metals. By reducing the metal-catalyzed oxidative stress, chelation therapy might prevent the oxidative modification of LDL cholesterol, a significant contributor to atherosclerosis.
Additionally, by removing calcium deposits, chelation might lead to the regression of plaque build-up in the arteries. This process would inherently improve blood flow, a crucial factor in cardiovascular health.
Looking Ahead: The Future of Chelation Therapy and Heart Disease
With the TACT providing a robust foundation, the intrigue surrounding chelation therapy in cardiology is undeniable. While the treatment isn’t mainstream, its potential benefits warrant further exploration, especially for specific patient groups.
Future studies might delve deeper into understanding which patient profiles stand to benefit the most. For instance, will the pronounced benefits observed in diabetic patients be replicated in larger, more diverse cohorts?

Unleash the Power of Oral Chelation Supplements: Understanding Heavy Metal Detoxification
In our increasingly polluted environment, it’s essential to explore innovative strategies to maintain our bodies in a state free from damaging toxins and impurities. Global pollution and ecological challenges have led to a surge of interest in oral chelation supplements, particularly those targeting heavy metal detoxification. Contaminated food, beverages, manufacturing processes, and pesticides can all contribute to an unwanted toxic burden.
Gaining insights into how these toxins can be expelled, if possible, and the extent of their potential harm to our health is crucial for everyone.
Prominent in the field of Chelation is Chelanox by Bionox®, a potent blend of botanicals engineered to counter the harmful impacts of heavy metals in our systems. We’ve meticulously researched each ingredient to curate the most effective formulation, and our goal is to enlighten you about the intricacies of Chelation and the rationale behind our ingredient selection.
Exploring Oral Chelation
Oral chelation represents a health or dietary intervention that leverages certain compounds or elements to purge the body of detrimental toxins, mainly heavy metals.
Known as chelating agents, these elements bind with the toxins and heavy metals inside the body, creating a stable chelate compound. This compound is then securely eliminated from the body through urine or feces. Initially employed to combat heavy metal toxicity, the use of chelation therapy has since broadened.
The introduction of oral chelation supplements like Chelanox has expanded its scope to encompass preventative health and overall wellness.
Health Enhancement Through Oral Chelation
Oral chelation could play a pivotal role in protecting and elevating your health. It presents several potential advantages, including, but not limited to:
- Diminishing Toxic Burden – The main advantage of oral chelation is the diminution of toxic burden, primarily heavy metals like arsenic, lead, and mercury. These toxins may accumulate in the body due to exposure from different sources, including contaminated food, environmental pollutants, and certain occupations.
- Maintaining Heart Health – Research indicates that chelation therapy could assist in decreasing the accumulation of specific types of plaque in arteries, thereby facilitating optimal cardiovascular wellbeing.
- Preserving Kidney Health: By alleviating the load of toxins and heavy metals, oral chelation supplements could help maintain the health of your kidneys.
- Preserving Neurological Function – Heavy metals have been linked to various neurological issues. Chelation therapy could help maintain neurological function by facilitating the expulsion of these metals from your body.
- Immune System – Chelation therapy can boost immune system health and general vitality by lessening the total toxic load on the body. As many diseases arise due to a weakened or hyperactive immune response, supporting this system is vital.
- Boosting Vitality Levels – Chelation supplement users often report a surge in vitality levels, likely due to a reduction in systemic stress caused by toxins and heavy metals. Increased vitality leads to an overall better feeling and increased activity, which is always beneficial!
- Gut Health – Chelation therapy could bolster gut health by expelling toxins from the body.
- Enhancing Skin Health – By facilitating the expulsion of toxins, chelation therapy might boost skin health, leading to a cleaner, more glowing complexion.
- Maximizing Nutrient Uptake – Reduced toxic interference may allow the body to absorb and utilize essential nutrients from your diet more effectively.
- Maintaining Liver Health – The liver plays a key role in detoxification within the body. Chelation could foster healthier liver function by assisting the body in toxin removal.

Reducing toxic load
Oral chelation reduces the body’s toxic load primarily through the action of chelating agents, which are substances that can bind to heavy metals and other toxins in the body, as previously mentioned, forming stable complexes that can be excreted.
Let’s examine the key ingredients in our Chelanox product to understand what they do and how they are used to reduce toxic load potentially:
- EDTA Calcium Disodium: This is a widely recognized and used chelating agent. A study in the Journal of Advancement in Medicine found that oral intake of EDTA can be beneficial for reducing lead toxicity.1
- Chlorella Algae: This freshwater algae is known for its detox-specific properties. A recent study published in Nutrition Research and Practice concluded that chlorella could decrease the amount of dioxin, a harmful toxin, in breast milk and might also decrease dioxin in the body generally. 2
- Modified Citrus Pectin (MCP): MCP is a type of pectin that has been altered to be more easily absorbed by the digestive tract. A study in Phytotherapy Research indicated that MCP can help reduce lead levels in the body. 3
- Cilantro Leaf Extract: A study that was published in the Journal of Traditional Chinese Medicine suggests that cilantro can expedite the body’s excretion of lead and mercury. 4
- Shilajit: Shilajit, a substance found in the rocks of the Himalayas, is rich in fulvic and humic acids, which may possess metal chelating properties, according to a study in the Journal of Ethnopharmacology. 5
- Zeolite: Zeolites are volcanic minerals that can act like magnets for toxins. Research has shown that zeolite clinoptilolite can trap and remove harmful toxins, including heavy metals, from the body. 6
- N-Acetyl Cysteine (NAC): NAC is an antioxidant that supports the bodys detoxification pathways. It’s known to enhance the production of glutathione, a compound that helps the body deal with toxicity. 7
- Alpha Lipoic Acid (ALA): ALA is a potent antioxidant that can bind with toxic free radicals and help eliminate them from the body. A study in Free Radical Biology & Medicine found that ALA can support the body in detoxifying from heavy metals. 8
- Uva Ursi Leaf Powder and Milk Thistle Seed Powder: These ingredients, traditionally used in herbal medicine, are included for their diuretic and liver-supporting properties, respectively, thus aiding in the detoxification process. 9, 10
How does oral chelation enhance heart health?
Chelation therapy, particularly intravenous EDTA chelation, has been studied for its potential benefits in treating cardiovascular disease, mainly by addressing atherosclerosis. Atherosclerosis is a condition characterized by the buildup of plaques in the arteries.
These plaques, primarily comprised of cholesterol, fat, and calcium, can restrict blood flow and potentially lead to severe cardiovascular events like heart attack or stroke.
While the mechanism isn’t entirely understood, some theories suggest that the calcium-disodium form of EDTA could bind with the calcium in these plaques, thus helping to reduce their size and improve blood flow. For this reason, we use this form of EDTA in Chelanox.
One of the most significant studies in this area is the Trial to Assess Chelation Therapy (TACT). This double-blind, placebo-controlled study, sponsored by the National Institutes of Health, was designed to determine the safety and effectiveness of EDTA chelation therapy in individuals with coronary artery disease.
The results, published in the Journal of the American Medical Association (JAMA) 11, showed that a course of 40 infusions of a high-dose multivitamin and disodium EDTA chelation solution modestly reduced the risk of adverse cardiovascular outcomes, including recurrent heart attacks, stroke, and death, among study participants who had previously suffered a heart attack.
Additionally, a follow-up study, TACT2 12, is currently underway to further explore the potential benefits of EDTA chelation therapy for post-heart attack patients with diabetes, as this subgroup seemed to benefit the most in the initial TACT study.
It’s important to note that oral chelation supplements may not offer the same level of cardiovascular benefits as the intravenous EDTA used in some of the studies, as the absorption rate of oral EDTA is lower. More research is needed to understand the potential cardiovascular benefits of oral chelation therapy fully. We can say that we use acid-resistant capsules in our chelation product so that our EDTA Calcium is absorbed better by bypassing the stomach and entering the intestines with greater potential uptake. Do not use EDTA in capsule form if it is not in acid resistance capsules, and only EDTA Calcium Disodium should be used for maximum effect and safety.
Binding of Chelating Agents to Toxins
When we say chelating agents bind to toxins, we are referring to a chemical process where the chelating agent forms a complex with the toxin. Chelating agents have multiple binding sites, which allows them to form stable complexes with metal ions or, in other words, to connect with and bind to them. This ability to bind is based on the atomic structure of the chelating agent and the toxin.
Take, for example, EDTA Calcium, one of our formula’s main ingredients and a chelating agent. EDTA has a negative charge, while heavy metals like lead and mercury have a positive charge. Due to this opposite charge, the EDTA can bind to the heavy metal to form a stable, neutral compound. This process is akin to a lock and key, where the chelating agent (the lock) fits perfectly with the metal ion (the key).
Where Do the Toxins Go?
Once the chelating agent binds to the toxin, forming a stable complex, this compound becomes water-soluble and can be safely eliminated from the body. This process mainly occurs through renal excretion, meaning the complex is expelled in urine. Some chelating agents can also promote toxin elimination through the feces.
What Tests Exist to See If My Toxic Load Was Lessened and If Chelation Is Working?
There are a few ways to measure the body’s toxic load and assess the effectiveness of chelation therapy:
Heavy Metal Testing: This can be done through blood, urine, or hair sample analysis. Before chelation therapy, a baseline measurement of heavy metal levels is taken. Then, additional measurements are taken to see if levels have decreased during or after therapy.
Chelation Challenge Test: A chelating agent is administered, followed by a urine collection over 24 hours. The urine is then tested for heavy metals. This test can reveal hidden stores of heavy metals in the body that aren’t apparent in a regular heavy metal test.
Other Lab Tests: Lab tests such as complete blood count, liver function tests, and kidney function tests can also indicate how well the body handles the toxin load and how effective chelation therapy is. These tests can identify any strain or damage to these organs caused by heavy metals.
Remember, though, that all medical procedures and tests should be conducted under the guidance of a qualified healthcare provider to ensure safety and effectiveness.
Kidney Function
several ingredients found in modern chelation support supplements may provide beneficial effects.
EDTA, or Ethylene Diamine Tetraacetic Acid, is a chelating agent known for its ability to bind to heavy metals in the body, which can potentially aid in their removal and thereby reduce the toxic burden on the kidneys. A study published in Biomedical Research International suggested the potential benefit of EDTA.
Chlorella Algae, known for its detoxifying properties, has also shown promise in improving renal function. Specifically, a study in the Journal of Medicinal Food suggested that Chlorella might improve renal function in dialysis patients by reducing the absorption of toxic substances in the intestines.
Modified Citrus Pectin, a specialized form of pectin, may be able to bind to and facilitate the excretion of a range of toxins, including heavy metals. This could potentially reduce the burden these toxins place on the kidneys, as highlighted in a study published in Phytotherapy Research.
Brain Detox
In terms of neurological function, several unique ingredients may provide support. For instance, EDTA may potentially reduce the neurotoxic effects of heavy metals by aiding in their removal. The accumulation of heavy metals in the brain has been linked to neurological conditions like Alzheimer’s disease.
Although more research is necessary, a review in the Journal of Alzheimer’s Disease discussed the potential benefits of chelation for Alzheimer’s disease.
Alpha Lipoic Acid, an antioxidant, has been associated with potential neurological benefits. A journal CNS & Neurological Disorders – Drug Targets review suggested that Alpha Lipoic Acid might offer neuroprotective effects in conditions such as multiple sclerosis and Alzheimer’s disease.
Lastly, Shilajit, a traditional Ayurvedic compound, has been associated with neuroprotective properties. A study in the Journal of Ethnopharmacology found that Shilajit helped improve memory and cognitive functions in rats, suggesting potential neurological benefits.
Remember that while these studies suggest potential benefits, they are not 100% definitive proof, and more research, including human trials, must be done to be definitive. Always make sure you consult with a healthcare provider before starting any new supplement program.
Liver Detox
The liver plays a key role in detoxification within the body. One of its main jobs is to filter out harmful substances from the bloodstream. When unhealthy heavy metals enter the bloodstream, it is the liver’s responsibility to help remove them, which can tax your system. Chelation therapy may support liver health by aiding in detoxification and reducing the overall toxic burden on the liver.
Here are some specifics on things that have been studied for their potential to support liver health:
- EDTA (Ethylene Diamine Tetraacetic Acid): As a chelating agent, EDTA binds to heavy metals and helps remove them from the body. This can potentially reduce the strain on the liver, which otherwise would have to work harder to remove these toxins. A study published in the Journal of Inorganic Biochemistry demonstrated the ability of EDTA to chelate cadmium and reduce its toxic effects in the liver, potentially preserving liver health 13.
- Milk Thistle Seed Powder: Milk thistle is known for its hepatoprotective properties, which can protect the liver from damage. A review published in the Journal of Veterinary Internal Medicine reported that silymarin, an active compound in milk thistle, can help protect the liver from toxins, including certain heavy metals 14.
- NAC (N-Acetyl Cysteine): NAC is a powerful and well-known antioxidant that can help to neutralize harmful free radicals in the body. A World Journal of Gastroenterology study reported that NAC may help reduce liver damage caused by various toxic substances, including heavy metals 15.
Chelation Supplements: A Preventive Measure for Health, Not a Cure for Severe Disease
Chelation therapy can often be misunderstood when implemented via oral supplements (oral chelation). Chelation supplements are preventative, not a panacea or cure-all, capable of curing severe diseases and chronic health conditions.
Oral chelation supplements, like Chelanox, are preventive measures that aim to reduce the toxic load in the body. They are not designed to cure severe diseases but rather to support overall health and potentially reduce the risk of certain health issues.
Chelation supplements work by binding to toxic metals in the body and aiding in their removal. These toxins, including heavy metals like lead, mercury, and arsenic, can build up over time due to various factors such as environmental pollution, consumption of certain foods, and exposure to some types of industrial work. Over time, this toxic load can contribute to many health issues, including cardiovascular disease, neurological disorders, and kidney damage. By helping to reduce this toxic load, chelation supplements can potentially support overall health and wellness.
Ingredients in chelation supplements like EDTA, Chlorella Algae, and Modified Citrus Pectin have been shown in studies to bind to toxins, potentially aiding their removal from the body. This does not mean they can cure diseases caused by these toxins, but they may help reduce the risk or severity of such diseases by limiting the body’s exposure to these harmful substances.
Chelation supplements can’t replace conventional treatments for severe diseases. Chelation supplements are not likely to reverse these conditions or act as a standalone cure for individuals with significant health conditions like late-stage cardiovascular disease, advanced kidney disease, or serious neurological disorders.
Severe diseases typically require comprehensive treatment plans overseen by healthcare professionals, including medication, lifestyle changes, and in some cases, surgical interventions.
However, the preventive aspect of chelation supplements really shines when they are used as a part of an overall health maintenance regimen. They may help the body manage and eliminate toxins more effectively, contributing to better overall health and potentially reducing the risk of certain diseases. This, combined with a healthy diet, regular exercise, and regular medical check-ups, can be a robust strategy for disease prevention and health promotion.
So, while chelation supplements like Chelanox can be a valuable addition to a health maintenance regimen, it’s crucial to understand their role. They are preventive, not curative, measures.
As always, it’s essential to consult with your healthcare provider before starting any new supplement regimen, particularly for individuals with existing health conditions or those on other medications. This ensures that the supplement will not interfere with any ongoing treatments or medications and that it’s a suitable addition to your personal healthcare plan.
Heavy Metals and Nitric Oxide Synthase
Introduction
Heavy metals, such as lead, mercury, cadmium, and arsenic, are environmental pollutants that can accumulate in the body and pose significant health risks. One of the lesser-known consequences of heavy metal exposure is the negative impact on nitric oxide synthase (NOS) production. NOS is an enzyme responsible for producing nitric oxide (NO), a signaling molecule that plays a crucial role in various physiological processes, including vasodilation, immune response, and neurotransmission. This article will discuss the mechanisms through which heavy metals can decrease NOS production, the health implications of this reduction, and strategies to counteract these effects, with references to scientific studies supporting these claims.
Mechanisms of Heavy Metal-Induced NOS Inhibition
A. Oxidative Stress
Heavy metals can induce oxidative stress, which is characterized by an imbalance between the production of reactive oxygen species (ROS) and the body’s antioxidant defense mechanisms (1). Excessive ROS production can lead to the inactivation of NOS and a decrease in NO production (2). Oxidative stress also contributes to the uncoupling of endothelial NOS (eNOS), a process in which the enzyme produces superoxide instead of NO, further exacerbating the negative effects on NOS activity (3).
B. Disruption of NOS Expression and Function
Heavy metals can directly interact with NOS enzymes or alter their expression, decreasing NO production (4). For example, cadmium has been shown to inhibit NOS activity by displacing essential cofactors, such as zinc, which are necessary for proper enzyme function (5). Additionally, heavy metals can interfere with the cellular signaling pathways that regulate NOS expression, ultimately suppressing enzyme production (6).
C. Inhibition of NO Bioavailability
Heavy metals can also decrease NO bioavailability by increasing the production of molecules that scavenge and inactivate NO, such as asymmetric dimethylarginine (ADMA) (7). ADMA, an endogenous inhibitor of NOS, competes with L-arginine, the substrate for NOS, for binding to the enzyme, thereby decreasing NO production (8).
Health Implications of Heavy Metal-Induced NOS Inhibition
A. Cardiovascular Disease
Decreased NOS activity and NO production from heavy metal exposure can impair endothelial function, reducing vasodilation and increasing blood pressure (9). This can contribute to the development of cardiovascular diseases, such as atherosclerosis and hypertension (10).
B. Neurological Disorders
NO is essential for normal neurotransmission and brain function. Reduced NOS activity and NO production due to heavy metal exposure can lead to altered neurotransmitter release, synaptic plasticity, and neuronal survival, contributing to the development of neurological disorders such as Parkinson’s disease and cognitive impairment (11, 12).
C. Impaired Immune Response
NO plays a critical role in the immune response by modulating the function of immune cells and influencing cytokine production. Reduced NO production due to heavy metal-induced NOS inhibition can impair the immune system’s ability to fight off infections and maintain proper inflammatory responses (13).

Strategies to Counteract Heavy Metal-Induced NOS Inhibition
A. Chelation Therapy
Chelation therapy involves the administration of chelating agents, such as ethylenediaminetetraacetic acid (EDTA) or dimercaptosuccinic acid (DMSA), which bind to heavy metals and facilitate their excretion from the body. By reducing the body’s burden of heavy metals, chelation therapy can help restore NOS activity and improve overall health (14).
B. Antioxidant Supplementation
Antioxidants, such as vitamins C and E, can help counteract oxidative stress from heavy metals and protect NOS activity (15). Supplementation with antioxidants may help restore NO production and support overall health in individuals exposed to heavy metals.
C. Nutritional and Lifestyle Interventions
Consuming a diet rich in antioxidants, essential nutrients, and anti-inflammatory compounds can help support NOS activity and counteract the effects of heavy metal exposure (16). Additionally, engaging in regular physical activity, maintaining healthy body weight, and avoiding exposure to environmental pollutants can further protect NOS function and overall health.
Conclusion
Heavy metals can negatively impact nitric oxide synthase production through various mechanisms, including inducing oxidative stress, disrupting NOS expression and function, and inhibiting NO bioavailability. The detrimental effects of heavy metals on NOS activity can contribute to the development of cardiovascular diseases, neurological disorders, and impaired immune responses. Chelation therapy, antioxidant supplementation, and nutritional and lifestyle interventions can be employed to counteract these effects. Individuals can proactively protect their health and mitigate the risks associated with heavy metal exposure by understanding the relationship between heavy metals and NOS production.
A Comprehensive Approach to Support NOS Production
This article discusses how can some components contribute to heavy metal detoxification and supports NOS production.
EDTA
Ethylenediaminetetraacetic acid (EDTA) is a well-known chelating agent that binds to heavy metals, such as lead, cadmium, and mercury, facilitating their excretion from the body (17). By removing heavy metals, EDTA can help restore NOS activity and mitigate the negative effects of these metals on nitric oxide (NO) production (18).
Modified Citrus Pectin
Modified citrus pectin is a form of pectin that has been altered to improve its bioavailability and absorption. It has been shown to bind and remove heavy metals from the body, such as lead, mercury, and cadmium (19). Modified citrus pectin can help protect NOS activity and support NO production by aiding in heavy metal detoxification.
Chlorella
Chlorella is a single-celled green alga that has been shown to possess heavy metal-binding properties, particularly for mercury (20). By assisting in removing heavy metals from the body, chlorella can help alleviate the negative effects of these metals on NOS production and support overall health.
Cilantro
Cilantro, also known as coriander, has been shown to have heavy metal-chelating properties, particularly for lead and mercury (21). By aiding in detoxifying heavy metals, cilantro can help protect NOS activity and support NO production.
Shilajit
Shilajit, a natural resinous substance found in the Himalayas, has been reported to have antioxidant and anti-inflammatory properties, which may help counteract heavy metal-induced oxidative stress and inflammation (22). Shilajit can help protect NOS activity and maintain NO production by reducing oxidative stress. Additionally, shilajit has been reported to possess metal-chelating properties, which may further contribute to its heavy metal detoxification effects (23).
Zeolite
Zeolites are natural or synthetic minerals with a unique porous structure, which allows them to bind to and trap heavy metals, such as lead, cadmium, and mercury (24). By assisting in removing heavy metals from the body, zeolites can help protect NOS activity and support NO production.
