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 needs tiny amounts of trace elements and metals to function optimally.

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

Which metals are in the human body?

Elements listed in the periodic table are either metallic, non-metallic, or metalloid elements. These elements enter the body in a number of ways, most commonly through the mouth, nasal passages, and skin. They are regularly present in the human body and in small quantities are not a cause for concern.

When it comes to health and nutrition, items are generally divided into essential and non-essential. The essential trace elements include zinc, copper, chromium, cobalt, manganese, selenium, iodine and molybdenum. Metallic ions like iron play a vital role in the proper functioning of the body. For example, iron is an important component in blood formation.

The body needs cobalt to produce enzymes that are needed to synthesize hemoglobin. Selenium, in turn, is necessary for protein production. Everyone knows that calcium is essential for bone repair and development. However, people often forget that it is a metal too.

Even non-essential elements have practical uses in almost every industry. Lithium, for example, is processed into medicines. These are given to people who are suffering from different types of mental illnesses such as depression and mania. Other metallic elements such as arsenic, nickel and cadmium are known to be carcinogenic. Mercury and arsenic are highly toxic.

Because these are naturally found in the food we eat and even in the air we breathe, even those in good health have these metals in their systems. Although trace elements are generally required by the body in an amount of just under 100 mg / day, a smaller amount can cause chronic illness. In some cases, it can damage vital organs and even lead to death.

Our body needs trace elements. Using less than 100mg / day can cause element-associated diseases.

On the other hand, a higher exposure to elements and heavy metals can lead to excessive amounts being present in the body. High amounts and prolonged exposure can build up to toxic values. This, in turn, can lead to poisoning, cancer, and other adverse reactions that harm the body. In some cases, toxic exposure to metals can lead to death.

This table lists the permissible daily doses (PDE) for essential and non-essential trace elements in the body [1]:

Coated silver nanoparticles are contained in a porous coating. This coating allows only a small amount of the silver to pass through the coating. This technology makes coated silver safe and effective. *

How does silver behave in the human body?

One of the natural metals in the human body is silver. Silver is naturally water-soluble. Here, too, due to differences in how it is manufactured, it can dissolve in water at different rates, depending on how it was synthesized.

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

The most commonly reported side effects of repeated or above-average exposure to silver are argyria and argyrosis. These conditions are characterized by the appearance of bluish-gray skin or eyes. Although both conditions are often cited as side effects of exposure to silver, they are very rare. Recorded cases show that these conditions occur after ingestion of inferior or homemade silver in abnormally high amounts and for an extended period of time. In addition, there is no evidence that silver has negative effects on human health, even in cases where argyria and argyroses appear [2] *.

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

Silver can easily cross the blood-brain barrier. It can support the transport of nutrients throughout the body and helps to generate energy.

Silver has an excellent carrier capacity that helps it cross the blood-brain barrier. In this way, silver can help the body deliver energy and nutrients more efficiently. Body functions, including cell repair and regeneration, are more effective and faster. *

Food and water contain silver compounds in the form of silver nitrate and silver chloride. In addition, it is also used as an oxidizer, for various medical purposes, applied to surfaces as a disinfectant, and as an additive to consumer products such as socks and washing machines to prevent the growth of bacteria.

Due to its antibacterial properties, silver is also used for air purification in closed rooms. Uses are increasing in terms of applications and frequency of use. For example, people are naturally exposed to silver through the environment and a growing number of consumer products.

The EPA [3] found in a report that nanosilver additives are processed in different ways. These variations can explain the differences in the way nanosilver reacts with the body. For example, it was noted in the report that only silver nanoparticles that have oxidative capacity have antibacterial properties.

Why is coated colloidal silver the safest?

First of all, how does coated silver work? Both the processing techniques used and the final presentation help make this form of nanosilver the better choice among colloidal silver. Here are four reasons why coated colloidal silver is better than any other nanosilver compound [4] *:

  • For sure. Every silver nanoparticle is coated. It remains well soluble in water and most forms of liquids. This means that when it is introduced into your body, it leaves the body through the normal excretory routes *.
  • Effective. Each molecule of the silver nanoparticle is less than 10 nanometers in size. As a result, it is quickly absorbed and is highly bioavailable. That means the body can use it almost immediately. *
  • Stable. In contrast to uncoated colloidal nanosilver, coated colloidal silver enables the controlled release of silver ions. This way it works quickly, does not overwhelm the body and lasts longer. *
  • Economical. Only one drop of Coated Colloidal Silver contains up to 20,000 ppm of silver nanoparticles. That's so much more than what any other brand of colloidal silver can deliver for the same amount. So while the cost per bottle may seem more expensive, the amount needed for potency is minimal, so each pack will last longer. *

Coated Colloidal Silver is pioneering the next generation of nanosilver nutritional supplements by introducing these four standards into its manufacturing process and end product.
