Rubidium

Rubidium is an alkali metal chemically similar to potassium and is ubiquitously present in mammalian tissues, with humans typically carrying 360–1,000 mg total body rubidium. Despite its consistent pr...

• Rubidium Is Present In All Body Tissues And Follows Potassium Distribution, Suggesting It May Substitute For Potassium In Some Cellular Transport Processes
• Preliminary In Vitro And Animal Data Suggest Rubidium May Have Mild Anxiolytic Or Antidepressant Activity, Possibly Through Interaction With Serotonergic Systems
• Some Research Suggests Rubidium Uptake Is Altered In Cancer Tissue Compared To Normal Tissue, Making It A Potential Diagnostic Or Investigational Marker
• No Confirmed Beneficial Biological Role Or Therapeutic Benefit In Humans Has Been Established

Note No established RDA or UL; evidence for essentiality or supplemental benefit is absent Note Rubidium chloride administered at high doses in animal studies displaces potassium and causes hypokalemia-like effects
