Germanium is surely an ample factor and is particularly ranked as the fifteenth most plentiful element from the earth’s crust. Germanium just isn't existing in its pure elemental type and largely extracted from its zinc ore (sphalerite) and from ores of copper, silver and direct.

The suitable dose of germanium depends on many factors like the user's age, health, and a number of other other conditions. Presently You can find not enough scientific facts to determine an correct selection of doses for germanium.

Germanium is considered a technological know-how-vital ingredient. Germanium just isn't regarded as A necessary factor for virtually any residing organism. Much like silicon and aluminium, By natural means-occurring germanium compounds are typically insoluble in water and therefore have minimal oral toxicity. Nevertheless, synthetic soluble germanium salts are nephrotoxic, and artificial chemically reactive germanium compounds with halogens and hydrogen are irritants and toxins.
