Also known as:  Argent Colloïdal, Argent Ionique, Argent Natif, Argentum Metallicum, Colloidal Silver Protein, Ionic Silver, Native Silver, Plata Coloidal, Protéine d'Argent, Silver, Silver Alginate, Silver Protein, Tetrasilver Tetroxide, Tétroxyde de Tétra-Argent

Diseases and Conditions

Reliable scientific evidence does not support the use of colloidal silver dietary supplements for any disease or condition. Silver has no known function or benefits in the body when taken by mouth and is not a nutritionally essential mineral or a useful dietary supplement.

Generally, people may be exposed to silver, usually in tiny amounts, through air, water, and food, and in certain activities such as jewelry-making or soldering, therefore it is not effective when supplemented.

Safety

Colloidal silver is likely unsafe to use orally, topically, and intravenously. Intake of colloidal silver should not exceed 14 mcg/kg/day for a 70kg person. Using colloidal silver supplements combined with other silver from dietary sources can easily lead to excess amounts and increase the risk for side effects.

It is unsafe for pregnant and breastfeeding women to consume colloidal silver orally, topically, or intravenously; babies who have been exposed to silver have been linked to cases of developmental anomalies in the face, ear, and neck.

Children may use colloidal silver only with the supervision of a physician.

Adverse effects associated with colloidal silver include the following:

  • Stomach distress
  • Kidney damage
  • Fatigue
  • Skin irritation
  • Headaches

Death has also been reported after ingestion of colloidal silver. Although rare, silver toxicity may occur.

Medication Interactions

Colloidal silver has moderate interactions with the following medications:

  • Hepatotoxic drugs
  • Levothyroxine
  • Penicillamine
  • Quinolone antibiotics
  • Tetracycline antibiotics

Colloidal silver may be hepatotoxic and preliminary animal research suggests that silver can adversely affect the liver. In theory, concomitant use with hepatotoxic drugs might increase the risk of liver damage. Levothyroxine may have reduced absorption if given with colloidal silver. In theory, drugs such as penicillamine (Cuprimine) may also have reduced absorption if given with colloidal silver. In theory, quinolones such as ciprofloxacin (Cipro), norfloxacin (Noroxin), ofloxacin and others might have reduced absorption if given with colloidal silver. Lastly, in theory, drugs such as tetracycline might have reduced absorption if given with colloidal silver.

Supplement and Food Interactions

Colloidal silver may have interactions with the following supplements and herbs:

  • Hepatotoxic herbs and supplements, such as:
    • Androstenedione
    • Chaparral
    • Comfrey
    • DHEA
    • Germander
    • Niacin
    • Pennyroyal oil
    • Red yeast
  • Iodine

Concomitant use with other potentially hepatotoxic products might increase the risk of liver damage. Evidence from animal research suggests that silver protein inhibits the absorption of iodine.

Dosage

The correct dosage of any supplement requires a comprehensive analysis of many factors including your age, sex, health conditions, DNA, andlifestyle. 

  • For skin graft donor wounds, it is recommended to take a silver-containing Hydrofiber®, Aquacel®, until re-epithelialization occurrs.
  • For ulcers, it is recommended to use AQUACEL® Hydrofiber® dressings, left in place for up to seven days or changed earlier as clinically indicated, for eight weeks or until healing.
  • For wound healing, it is recommended to take a topical ionic silver dressing (Aquacel® Ag) for ten days (duration varying by patient).
  • For ocular disorders in newborns, the recommended dosage is one drop of ten percent silver vitellinate or saline solution in each eye shortly after birth.

Colloidal silver is not regularly found in foods.
