One of the most common misconceptions when it comes to health is that all metals in the human body are harmful. Most people associate heavy metals with poisoning and other toxic effects. Few understand that the body requires minute amounts of trace elements and metals to function optimally.

One misconception about metals is that they are harmful to the body.

What metals are in the human body?

Elements that are listed on the periodic table are either metallic, non-metallic, or metalloids. These elements enter the body via a number of pathways, most commonly through the mouth, nasal passages, and skin. These are regularly present in the human body and, at low levels, do not pose any cause for concern.

When it comes to health and nutrition, elements are generally grouped into essential and non-essential. Essential trace elements include zinc, copper, chromium, cobalt, manganese, selenium, iodine, and molybdenum. Metallic ions such as iron play crucial roles for the body to function well. Iron, for one, is a key constituent in blood production.

The body requires cobalt to produce enzymes needed for the synthesis of hemoglobin. Selenium, on the other hand, is necessary for protein production. Everybody knows calcium is essential for bone repair and development. Although, people tend to forget it’s metal too.

Even non-essential elements have practical applications in almost every industry. Lithium, for instance, is manufactured into drugs. These are administered to people suffering from different kinds of mental illness, such as depression and mania. Other metallic elements such as arsenic, nickel, and cadmium are known carcinogens. Mercury and arsenic are highly poisonous.

As these are naturally found in the food we eat and even in the air we breathe, even individuals in good health will have these metals in their system. Although trace elements are generally required by the body at just below 100mg/day, having less can cause chronic diseases. In some cases, it can damage vital organs and even lead to death.

Our bodies need trace elements. Having less than 100mg/day may cause element associated diseases.

On the other hand, higher exposure to elements and heavy metals can cause excess amounts to be present in the body. High amounts and prolonged exposure can build up to toxic levels. In turn, this can lead to poisoning, cancer, and other adverse reactions that harm the body. In some cases, toxic exposure to metals can lead to death.

Listed in this table are the Permitted Daily Exposure (PDE) levels of essential and non-essential trace elements inside the body [1]:

Coated Silver nanoparticles are contained in a porous coating. This coating permits only a small part of silver to pass through the coating. This technology is what makes coated silver safe and effective. *

How does silver behave in the human body?

How does silver behave in the human body?
One of the natural metals in the human body is silver. Silver is naturally water-soluble. Again, due to differences in manufacturing, it may dissolve in water at different rates inside the body depending on how it was synthesized.

Silver is a naturally occuring water-soluble metal present in the body.

The most commonly cited side effects of repeated or of higher than normal exposure to silver are Argyria and Argyrosis. These conditions are characterized by the appearance of bluish-grey skin and eyes, respectively. Even though both conditions are often cited as side effects of silver exposure, these are very rare. Recorded cases show these conditions occur after ingesting low-quality or homemade silver in abnormally high quantities, and for a prolonged period of time. Furthermore, there is no evidence that silver causes any ill effects on human health even in cases where argyria and argyrosis are present [2] *

There is no overwhelming evidence to show that silver in the body is deposited in the liver or kidneys. There is also no conclusive proof to show it affects reproduction. [2]*

Silver can cross the blood-brain barrier easily. It may support nutrient transport throughout the body and helps with energy.

Silver has excellent carrier capacity that helps it cross the blood-brain barrier. This way, silver can support the more efficient delivery of energy and nutrients in the body. Body functions, including cellular repair and regeneration, happen more effectively and more rapidly as a result.*

Food and water contain silver compounds in the form of silver nitrate and silver chloride. Other than that, it is also used as an oxidation agent, for various medical uses, applied to surfaces as a disinfectant, and added to consumer products like socks and washing machines to prevent the growth of bacteria.

Because of its antibacterial properties, silver is also used to purify air in enclosed spaces. The uses are growing in terms of applications and frequency of use. Thus, people are naturally exposed to silver from the environment and from a growing number of consumer goods.

The EPA [3] noted in a report that nanosilver supplements are processed in different ways. These variations may account for the differences in the way nanosilver reacts with the body. For instance, it was noted in the report that only silver nanoparticles that exhibit oxidative capacity have antibacterial properties.

Why is coated colloidal silver the safest?

Why is coated colloidal silver the safest?

Before anything else, how does coated silver work? Both the processing techniques used and its final presentation help make this form of nanosilver the better choice among colloidal silvers. Here are four reasons why Coated Colloidal Silver is better than any other nanosilver preparation [4]*:

  • Safe. Each silver nanoparticle is coated. It remains highly soluble in water and most forms of liquids. That means, when it is introduced inside your body, it leaves the body via normal excretion routes.*
  • Effective. Each silver nanoparticle molecule measures less than 10 nanometers. That gives it rapid absorption rates and is highly bioavailable. That means the body can use it almost immediately.*
  • Stable. Unlike uncoated colloidal nanosilver, Coated Colloidal Silver facilitates the regulated release of silver ions. This way, it is fast-acting, does not overwhelm the body, and lasts longer.*
  • Economical. Just one drop of Coated Colloidal Silver contains up to 20 000 ppm of silver nanoparticles. That is so much more than what any other brand of colloidal silver can deliver for the same quantity. So, while cost per bottle may appear more expensive, the amount required for potency is minimal so each package lasts longer.*

Coated Colloidal Silverpioneers the next generation of nanosilver supplements by introducing these four standards into its manufacturing process and final product.
