The bacteria-fighting action of silver has been harnessed before penicillin was discovered in 1928. Physicians and medical practitioners used to prescribe silver as a cure for almost all kinds of illness.*

After antibiotics snatched the spotlight, silver was bumped off from the medical scene for a while. In recent decades, silver made a powerful comeback that has since expanded its applications. Medical implants and medical devices are now lined with silver nanoparticles to prevent surgical site infections. Bandages are also lined with silver to promote faster wound healing.

Silver has also been adopted for consumer and commercial uses in other industries. For example, the textile industry now produces fabrics lined with silver [1]. Samsung introduced a model of washing machines that use silver ions to remove bacteria from used clothes and claims it can keep bacteria off for up to a month after the last wash [2]. It is also increasingly added to products used to disinfect surfaces and even as air purifiers for enclosed workplaces [1].

Without a doubt, exploiting colloidal silver antibacterial properties is the key driver for the growing research and use of silver. Although the properties of silver to potentially provideimmune support have also invited much interest in recent years.

The antimicrobial properties of colloidal silver are driving scientific research and more mainstream silver use.

Do Silver Particles Affect Human Immune Response?

Do Silver Particles Affect Human Immune Response?

Silver has a long history of use in promoting and restoring health. Some claim that silver is the ultimate immune defense support. There is evidence showing that colloidal silver kills (Censored by FDA). That includes (Censored by FDA) and (Censored by FDA).[3]

Although several studies have demonstrated how silver nanoparticles specifically interact with the immune system [4], the findings remain varied and inconclusive.

The bigger question is how taking silver for immunity support affects the body. An answer would be timely. Given the wider use of silver across industries, people, now more than ever, are exposed to silver, with or without their knowledge. Thus, it is vital to know if silver is beneficial or harmful to the body, and if so, how.

How does the human body interact with silver?

Silver can enter the human body via different pathways. One of these is by ingesting it. Silver is also added to drinking water to kill pathogens and improve the safety of drinking water. Thus, it can enter the body through silver-containing food and water via the digestive tract.

Silver is also present in the air we breathe. So, another way it can enter the body is through the nasal passage. Tiny nanosilver particles can also enter the body through the skin — the third pathway. The last is via mother-to-baby transmission.

Since silver is not an element naturally found inside the body, antibodies will be produced in greater quantities as soon as it is detected in the system. These antibodies will then rush to the body’s defense in an attempt to neutralize silver. From there, it will be assimilated into immune cells.

How it becomes enveloped into the system and whether or not the interaction will have beneficial or harmful effects depends on several factors. The characteristics of the nanosilver particles used will be of prime importance. [4]

How does the human body interact with silver?

Does the human body react the same with any type of silver?

Silver is available naturally in the environment. It can also be produced in many different ways. The resulting silver can be pure or made into a compound, positively charged, negatively charged, or having a neutral charge. It will also vary in physical and chemical characteristics. These differences are responsible for the variations in reaction exhibited by the body towards it.

In a study, researchers showed how nanosilver can suppress or stimulate natural immunity. It was determined that its physical and chemical characteristics determine if it is compatible or not with the human body. [5]

Coated colloidal silver for immune support

Coated colloidal silver for immune support

Why use colloidal silver for immune support? There are clear advantages versus using liquid silver ions or silver in any other formulation or preparation.

Based on the best available evidence, here’s how differences in the physical and chemical structure of silver affect the body. [4]*

  • Size. Smaller-sized colloidal silver nanoparticles are more easily assimilated by the body and metabolized by the kidneys. Thus, improving immunity faster. Equally important is that, since it is coated, it exits the body unlike uncoated colloidal silvers which get stuck inside.

Silver hydrosol, although made up of very tiny ionic silver, is highly reactive. Thus, it poses great risks to human health and safety. Larger silver particles, particularly those greater than 25nm are also unable to exit the body and are likely to result in side effects.*

  • Surface Area. The smaller the silver nanoparticles, the larger the surface area it occupies. Thus, the more diffused it is because it covers a larger surface area, the easier it is to become assimilated into cells and influence the rate of inflammation.
  • Shape. To be exact, the effectiveness of silver nanoparticles is determined by their shape in the context of where they are internally in the body, and what bacteria or viruses they are designed to attack. Spherical AgNPs, for instance, have a shorter uptake via the digestive tract compared to nanorods. In a study of e.coli, the researchers observed that triangular-shaped AgNPs were more effective in attacking this pathogen. Although, spherical AgNPs are gentler, safer, and do not cause inflammation. [6]*

  • Presence or absence of and type of coating or capping. Adding a capping or coating decreases the toxic levels of AgNPs to cells, which is also termed, “cytotoxicity”. Coating helps stabilize AgNP levels in the system by gradually releasing AgNP ions. Uncoated AgNPs have been found to decrease cell viability with either prolonged intake and high dosage, or both. This is why you should never use ionic silver as a supplement. [7]*

Using AgNPs as an immune booster also requires the release of cytokines to be regulated well. Too little will not promote anti-inflammatory mechanisms necessary to charge up the immune system and restore a person to ideal health. However, very high levels of cytokines can also trigger the body to attack itself.

The evidence clearly shows that just because one type, presentation, or brand of silver nanoparticles behaved in a particular manner, the same behavior cannot be automatically expected of another AgNP formulated and presented differently [8]. This fact stresses the importance of making the right choice when taking colloidal silver as a supplement.

How and why use Coated Silver?

In fact, it’s not enough to pick up colloidal silver. Choose Coated colloidal Silver. Here are the most compelling reasons why: [9]

  • Colloidal. Greater surface area increases efficacy. Of the silver supplements commercially available, only Coated Silver delivers uniformly-sized silver nanoparticles 10 to 12 nanometers in size. [9]*
  • Non-ionic. Unlike ionic silver, Coated Silver does not overwhelm your cells and become toxic.*
  • Coated. Coated Silver delivers stable and safe silver nanoparticles.*
  • High concentration per drop. Coated Silver contains close to 20,000 parts per million of silver nanoparticles. That’s more than any other brand of silver in the market can deliver. Higher ppm means you’re getting more value out of every drop.*
