Heavy Metals in Supplements: What You Need to Know
Heavy metal toxicity in our food and supplements has now become a serious concern worldwide. Heavy metals, which are undetectable, odorless, and almost unnoticeable, are believed to be contributing to a variety of chronic illnesses.
Some dietary supplements can be harmful because they contain toxic chemicals or high levels of heavy metals like arsenic, mercury, or lead. Because these substances are not often specified on the product label, distinguishing between safe and harmful items can be challenging.
With the rise in popularity of dietary supplements, it is important to be aware of the potential risks associated with their use. In this article, we will look at what heavy metals are, how they accumulate in supplements, and what you need to know to make sensible choices about your health and wellness.
What are Heavy Metals?
Heavy metals are naturally occurring compounds found in the earth. They're utilized in several modern applications, including agriculture, medicine, and manufacturing. Heavy metals are substances that, even in low amounts, may be poisonous and harmful.
Heavy metals that might cause toxicity include the following:
- Mercury
- Cadmium
- Uranium
- Arsenic
- Nickel
- Lead
- Aluminum
- Thallium
- Others include manganese, iron, lithium, zinc, and calcium (Even excessive essential minerals could turn dangerous in certain situations)
What is Heavy Metal Toxicity?
The build-up of various heavy metals in your body is known as heavy metal toxicity. Every day, you are exposed to substantial amounts of heavy metals due to atmospheric and industrial variables, including the foods you consume and the air you breathe. Some of these metals, such as zinc, copper, and iron, are beneficial to your health in smaller doses. However, excessive exposure might result in heavy metal toxicity and cause illness.
Heavy metal build-up can alter the hormonal equilibrium of the body and produce a range of symptoms. Chronic tiredness, depression, anxiety, insomnia, and digestive issues are the most prevalent symptoms, and there is some evidence that heavy metals may lead to autoimmune illnesses.
Heavy metals can have a variety of effects on human health. They can cause cell damage by destroying our mitochondria (the energy-producing components of our cells), disrupting enzyme activity, and disrupting hormone function. According to preliminary evidence, heavy metals may also cause autoimmune disease as a result of the body overstimulating the immune system.
Heavy metals are also neurotoxins, which are extremely harmful to brain cells. Mercury and lead are the most harmful neurotoxins that disrupt neuron function and cause oxidative stress. Heavy metals induce cellular damage, which can have long-term and permanent consequences. Heavy metals are believed to have an impact on various health conditions such as obesity, ADHD, autism, Alzheimer's, Parkinson's, and heart disease.
How do Heavy Metals Get into Supplements?
Heavy metals are naturally existing elements of the earth's crust that are neither generated nor destroyed but rather redistributed.
Heavy metal distribution is not uniform, so some soils may contain higher levels of any of these chemicals due to natural processes or contamination factors in which heavy metals have been dispersed into the environment through human-caused processes such as mineral extraction, generation of electricity, and production of leaded gasoline.
Each heavy metal may be absorbed by a variety of plants as they develop. Certain plants have been shown to accumulate particular metals, such as cadmium in some genotypes of durum wheat or St. John's wort, and arsenic in a variety of seaweed species.
As a result, makers of nutritional supplements may find arsenic, cadmium, lead, and mercury in their components. A manufacturer's water supply or the use of non-food grade equipment can be two major possible causes of contamination.
Symptoms of Heavy Metal Poisoning
The following are some of the most prevalent warning indications that you may be experiencing with heavy metal toxicity:
- Chronic tiredness
- Autoimmune disorders, such as Lyme disease
- Weakness and feeling tired after a workout
- Irritation of the skin
- Neural system disorders
- Difficulty concentrating, brain fog, trouble with learning, and poor memory
- Anxiety or depression
- Dementia
- Sleeplessness
- IBS (irritable bowel syndrome) and other digestive problems
- Persisting aches and pains, such as fibromyalgia
- Tremors
- Affected motor control, speech, hearing, vision, and mobility
- Anemia
- Increased chance of heart attack
How to Know Which Supplements to Consume?
If you are worried about what could be hidden in your supplements, there are a few indicators you can check for. Although heavy metal toxicity is rare, you should always check the following factors.
Is the Supplement Really Important to You?
In a world where promising headlines, online advertisements, and well-intentioned suggestions from close friends and family often shape our choices, it's crucial to recognize that these sources may not always provide effective recommendations for dietary supplements. Instead, a more informed approach is to conduct the necessary tests, such as blood tests, to determine whether you truly require supplementation.
Before reaching for a supplement, it's essential to assess whether you can obtain the necessary vitamins, minerals, or substances from your regular diet. Exploring dietary and lifestyle changes may often prove sufficient to meet your nutritional requirements. Only when these changes are insufficient should you consider incorporating specific supplements, and even then, it is crucial to seek your doctor's recommendation.
By reframing our understanding of supplement choices, this approach prioritizes scientific evidence, objective testing, and professional guidance. It encourages individuals to take a holistic view of their nutrition and health, ensuring that supplementation is based on a genuine need rather than relying on unreliable sources or uninformed advice.
Look for the Science Behind it
Trustworthy supplements are always backed by peer-reviewed scientific research that validates their usage and effectiveness.
Also, it should be verified that the recommended dosage is scientifically validated, which would be addressed in the supporting research as well. More dosages may not necessarily result in greater benefits, so avoid excessive doses.
Consult Your Doctor if You Are on Medication, Pregnant, or Breastfeeding
Many supplements may interact with prescription medications. Check with your doctor to see whether the supplement can actually be safely used with your existing medications. Women who are pregnant or nursing should contact their doctor prior to starting any new supplements.
Ways to Choose a Good Supplement
Choosing the best supplement can be challenging. However, you can always check the following while searching for a good supplement.
1. Purchase Supplements From a Reliable Supplier
In an industry where not all supplements are closely monitored, it's concerning that some companies may bypass rigorous quality checks to verify the accuracy of product descriptions and the purity of their components. However, larger national brands often outperform smaller businesses in this regard, as they have the resources to implement comprehensive quality control methods.
To safeguard consumer health, it becomes crucial to reframe our understanding of supplement selection by prioritizing safety and quality control measures. Opting for trusted and established brands can provide a greater level of assurance regarding product authenticity and purity.
2. Ensure a Third-Party Certification on the Supplement Bottle
Many reputable third-party organizations perform supplement testing to ensure that what is on the label is in the container and that the product does not contain large quantities of pollutants, such as heavy metals. These credentials can be found on a supplement label.
Not every organization can afford it because this procedure is quite expensive. Some third-party websites perform supplement analysis and provide reports online as well. They provide lists of the best supplements.
3. Always Purchase Organic Herbal Supplements
Several herbal supplements have no third-party validation. To ensure the lowest amount of contamination, buy organic herbal supplements that are devoid of dangerous pesticides. Many reputable firms are glad to disclose information about where their herbs are procured. Buying from well-known brands also enhances the probability that the supplement includes an adequate amount of the beneficial component.
4. Always Select a Single-Ingredient Supplement
Supplements with a single component are more likely to have the amount of the declared content and are less likely to have significant levels of contamination. Organizations offering "proprietary blends" often do not disclose the ingredient quantities on their labels and should thus be avoided.
Some other points to increase supplement safety are:
- Take a supplement only for the specified duration
- Keep supplements in the proper environmental conditions, such as in a refrigerator or away from light
- Start with only one supplement at a time
- If you encounter any negative effects, immediately stop taking it and report it to your doctor
