Rubidium: biological information

Rubidium has no biological role but is said to stimulate the metabolism. It can accumulate ahead of potassium in muscle.

You can use this form to calculate how much rubidium your body contains. Enter your weight in either kilograms or pounds and click the "Calculate" button. You must enter a number, not text! Elements for which there are no data will always give a value of zero for the weight, no matter what you put in the weight box.

Hazards and Risks

Hazards and risks associated with rubidium: rubidium salts are generally inert, and their toxicity is almost always a consequence of the anion, not of the Rb+. Nevertheless ingestion should always be avoided. In the body, rubidium substitutes for potassium and too much can be dangerous. Large amounts cause hyperirritability and spasms.
