A single teaspoon of colloidal silver will offer approximately 75mcg of silver. This is considered a nutritional amount and can be for as long as you need. Any amount beyond 4 teaspoons will provide 300mcg, which is considered a therapeutic amount. In essence, the amount and frequency depend on the desired outcome. Even when the body is extremely toxic, however, no one should try to clear it up in one instance. While colloidal silver may possibly achieve such a goal, the five basic eliminatory channels may be overloaded for some time and, therefore, cause issues such as dizziness, extreme fatigue, headache nausea and even aching muscles. When taken orally, colloidal silver gets absorbed from the mouth right into the bloodstream. For fast absorption, it is recommended that you swish the solution in the mount and hold it under the tongue for some time.
