colloidal silver review

Marketed as a solution for a range of health problems, colloidal silver is a solution of tiny silver particles suspended in a liquid base. It’s classically taken orally, but some products are sprayed, applied to the skin, or injected into a layer.

Silver has been using in medicine for centuries, pushing like a cure-all for everything from tuberculosis and arthritis to herpes and cancer. Yet today, many alternative practitioners believe that colloidal silver offers health advantages by “boosting” immune function and preventing or treating infections, both familiar and severe.

Despite claims to the contrary, colloidal silver has no known function in the body. The U.S. Food and Drug Administration (FDA) ruled in 1999 that these colloidal silver products were neither safe nor effectual and sued some manufacturers over false health claims.1

Though many colloidal silver products were removed from drugstore shelves following the FDA ruling, they have as been rebranded as dietary supplements or homeopathic remedies, neither of which need FDA approval.

Health Benefits

Manufacturers of colloidal silver often largely claim that their products are capable of stimulating the immune system and aiding the body “heal” itself. Proponents believe that the supplement can aid in wound healing, develop skin disorders, and either prevent or luxury diseases like flu, pneumonia, herpes, eye infections, shingles, cancer, and AIDS.

Many of these arguments support the test tube studies in which colloidal silver is showing to exert influential antibacterial, antiviral, antifungal, and anti-inflammatory effects. What the studies fail to prove is what happens outside of the test tube.

When ingested, colloidal silver can cause toxicity and, in rare cases, death. Moreover, there remain little facts that silver exerts the same antimicrobial properties when internalized.

Eventually, the human body does not need silver. It is not an essential mineral and provides no biological function of any sort.

While silver toxicity is uncommon, silver can accumulate in the body over months and years. This can lead to severe disfigurement and potentially dangerous deposits in the liver, spleen, kidney, muscle, and brain, along with researching from Imperial College in London.2 

That is not to say that silver offers no health advantages. When used topically (on the skin), colloidal silver can help in healing and prevent infection.

Wound Healing

Some studies have explored the use of silver-containing dressings on skin ulcers and wounds. Lots of these have found that the silver particles exerted antibacterial properties that help the treatment of diabetic ulcers, skin grafts, bedsores, necrotizing fasciitis, and other grave skin injuries.

A 2018 study from Iran concluded that a relevant ointment containing silver nanoparticles was able to decrease skin inflammation during healing and speed the regrowth of skin compared to persons provided a placebo.3 

This recommends that the short-term, current use of silver-containing products have their place in treatment.

Possible Side Effects

People who take colloidal silver may not experience any instant side effects. The concerns are related more to the lasting consequences of colloidal silver use as particles slowly accumulate and embed themselves in organs and tissues, most especially the skin.

eventually, this can lead to a permanent, disfiguring condition called argyria in which tissues take on a bluish-gray discoloration.4  The gums are typically first affected, followed the skin, eyes, nails, and deeper tissue layers. Headache, fatigue, and myoclonic seizures may also happen.

Though it is unclear what toxicity silver poses to internal organs, animal studies have shown that extremely high levels can interfere with kidney and liver function, damage the central worried system, and instigate the release of calcium from bones. we didn’t know how silver affects copy or pregnancy. the National Toxicology Program issue the research and recommends that silver does not cause cancer.5 

There have been some deaths linked with colloidal silver use, including one case report published in Neurology in which a 71-year-old man died after taking everyday dose colloidal silver for four months.6 

Drug Interactions

besides potential health hazards, colloidal silver interacts with some medications. It also reduces their efficiency, increasing side effects, or impairing liver function. Probable interactions include:

  • Antiarrhythmic drugs like Cordarone (amiodarone)
  • Antifungals like Diflucan (fluconazole) and Sporanox (itraconazole)
  • Levothyroxine used to treat thyroid troubles
  • Methotrexate used to treat autoimmune disorders
  • Penicillamine used to treat rheumatoid arthritis
  • Quinolone antibiotics, counting Cipro (ciprofloxacin) and Penetrex (enoxacin)
  • Statin drugs as Pravachol (pravastatin) and Zocor (simvastatin)
  • Tetracycline antibiotics, counting Achromycin (tetracycline) and Minocin (minocycline)
  • Tylenol (acetaminophen)7 

Other drug interactions are possible, therefore suggest your doctor if you are taking colloidal silver, even for short-term use.

Dosage and Preparation

There is no safe dose of colloidal silver. Besides, it should know what point silver toxicity may occur. Part of the problem is that the attention of silver particles can vary from one brand to the next. Some include a few as 15 parts per million (ppm) while others are more than 500 ppm. Age, weight, and health status can also play a part.

Despite the FDA ruling, colloidal silver products are yet available as dietary supplements. Many of the product sells in liquid form. There are still colloidal silver generators you can buy that disperse silver particles into water. Colloidal silver soaps, mouthwash, eye drops, body lotions, lozenges, and nasal sprays also exist.

What to Look For

It is significant to remember that dietary supplements do not need to undergo research. Also safety testing that pharmaceutical drugs do. As such, features can vary considerably from one manufacturer to the next.

Unlike vitamin supplements, little colloidal silver products are willingly submitted for evaluation by an independent certifying authority as the U.S. Pharmacopeia (USP), ConsumerLab, or NSF International. As such, the buyer can be left blind as to what the product contains or how safe it is.

If you choose to buy a colloidal silver product, even for short-term use, choose those that specify the concentration in parts per million (ppm) on the product label (remembering that less is more).

Other Questions

If colloidal silver is insecure, why hasn’t the FDA banned it?

The FDA has banned it,1 but this only applies to its use as an over-the-counter medication, like aspirin.

When marketed like a dietary supplement, a product like colloidal silver does not fall under the same regulatory constraints. So long as the manufacturer does not make any health or medical claims, the product can be officially sold in the same way that vitamins, homeopathic remedies, and traditional Chinese medicines are.

That doesn’t mean that producers won’t suggest health benefits; they often do. But many of the claims are more slanting than direct, inferring that colloidal silver can “boost immunity” or “keep you from getting ill.” Other manufacturers are less subtle and will test the restrictions of the law by suggesting their supplement has antibiotic-like effects.


Very small evidence supports claims about the health benefits of colloidal silver. Taking large doses may carry important risks.

Until researchers have act more tests, a person should take other medications. He should ensure that he gets enough considerable evidence.
