Why is colloidal silver harmful?
If there is a deficiency of selenium in the body, silver will accumulate. Moreover, it will not only accumulate but also interfere with the further absorption of selenium. Therefore, in selenium-deficient regions, colloidal silver is a sentence for the thyroid gland.
Colloidal silver is especially dangerous in selenium deficiency and affects the thyroid for the following reason.
Selenium — the key to converting T4 → T3. In the thyroid gland, deiodinase enzymes (D1, D2, D3) work, in which selenium is embedded in the active center. These enzymes convert relatively "inactive" thyroxine (T4) into active triiodothyronine (T3).
In the case of selenium deficiency, this process is slowed down, and T3 becomes scarce, even if T4 is normal.
Silver competes with selenium in enzymes. When colloidal silver enters the body, ion-forming forms of silver can bind to sulfhydryl groups of proteins and active centers of enzymes, including those containing selenium.
If selenium is already deficient, silver effectively blocks the remaining active centers — deiodinase enzymes stop working even more. This is a direct path to hypothyroidism.
Silver and accumulation in thyroid tissues. The thyroid gland actively accumulates trace elements (primarily iodine and selenium). In selenium deficiency, instead of selenium, silver may be "incorporated" into proteins (based on chemical similarity and replacement of active centers). In the long term, this creates structural damage to the enzymes and proteins of thyroid tissue.
Amplification of autoimmune processes. Silver, trapped in thyroid proteins, alters their structure, making them "foreign" to the immune system. This increases the risk of autoimmune attacks (like Hashimoto's), especially if there is a concurrent deficiency of antioxidants (selenium, zinc, vitamin D, glutathione).
Vicious circle: less selenium → worse detox → more silver. The thyroid loses its ability to detoxify active forms of oxygen because glutathione peroxidases (selenoproteins) work less effectively. Silver remains in the tissue even longer, further worsening the situation.
As a result: in selenium-deficient regions, the intake of colloidal silver is essentially accelerated damage to thyroid enzymes, and many processes become irreversible.
