Rubidium: biological information
Rubidium has no biological role but is said to stimulate the metabolism. It can accumulate ahead of potassium in muscle.
Levels in humans
|Human abundance by weight||4600 ppb by weight|
|Human abundance by atoms||340 atoms relative to C = 1000000|

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.
