Is Dandelion Root Safe with Lithium?
Free · No account · based on published sources including NIH ODS, FDA drug labels, and peer-reviewed literature
Avoid Dandelion Root supplementation if you are taking lithium unless under direct medical supervision. If use is continued, serum lithium levels must be monitored frequently. Report signs of lithium toxicity including tremors, confusion, nausea, or irregular heartbeat immediately.
Why this interaction occurs
Dandelion Root has significant diuretic properties, increasing urinary output and reducing renal fluid and electrolyte retention. Lithium is eliminated almost exclusively by the kidneys and renal reabsorption closely mirrors sodium handling. Diuretic-induced sodium depletion stimulates compensatory renal sodium (and lithium) reabsorption, leading to elevated serum lithium concentrations and potential toxicity.
Evidence
Evidence level: moderate.
Reported safety data
The FDA’s adverse event reporting system (FAERS) has received 43,834 reports mentioning Lithium. This reflects reported cases involving the medication in general — not confirmed causation, and not specific to the Lithium + supplement combination on this page.
