Colloidal silver is an over-the-counter dietary supplement that has been used for centuries to fight all sorts of ailments and conditions, yet its medicinal validity today remains controversial. No scientific data exist to support claims that colloidal silver is beneficial to health either in preventing or curing disease. Unfortunately, colloidal silver recently has been found to produce major irreversible side effects.
Blue Skin
Chronic silver ingestion can lead to silver particles being deposited in the skin and internal organs, which is known as argyria. With silver particles in the skin, the skin becomes dramatically discolored, turning bluish-gray in color, a side effect that is not reversible even if the silver ingestion is discontinued. Furthermore, the skin areas of the body that receive the most exposure to the sun --- for example, the hands and arms, face and neck --- tend to manifest the most dramatic bluish gray discoloration. The eyes, nails, gums and internal organs also take on this irreversible condition. In 2009, the U.S. Food and Drug Administration issued a consumer advisory to warn the public about argyria as a permanent effect of colloidal silver products. If you are considering this supplement, consult with a dermatologist about colloidal silver effects.
Drug Interactions
Silver supplementation may have a negative interaction with certain medications that you may be taking. Colloidal silver may decrease the absorption of certain medications, thus rendering them less effective. Some examples include penicillamine, an arthritis medication; tetracycline and quinolone antibiotics; and thyroxine, a thyroid hormone-replacement drug for individuals diagnosed with hypothyroidism.
Kidney and Liver Problems
Colloidal silver products may cause damage to certain internal organs. Potentially serious side effects involving the kidneys and liver may result. Both of these organs are primary in maintaining the body's health by processing and removing impurities or toxic substances from the body. If you have a history of renal or liver disease, you should avoid this product.
Neurological Conditions
Other potential side effects of colloidal silver involve the neurological system. Colloidal silver has been linked with epilepsy or seizure activity as well as other neurological disorders. Also, silver products may lead to headaches. It is best to first speak with your doctor before beginning any health supplement.
