Lithium and Potassium: what the published research says

PubMed indexes 7 records that name Lithium and Potassium together, either in the title or in an interaction, co-administration, or pharmacokinetic context. Each one is listed below with its study design and, where the abstract states one, the authors’ own conclusion, quoted and linked. This page reports that literature. It does not tell you whether to combine them.

Read this first

An evidence index, not guidance.

Every statement below is attributed to a named, dated, linked source.

This page lists published research relevant to Lithium and Potassium. It deliberately does not state whether the combination is safe, whether it interacts, in which direction, at what dose, or how far apart to take them.

The research

7 studies naming Lithium and Potassium.

Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.

ESR dosimetry with lithium, potassium, and sodium compounds.

Applied radiation and isotopes : including data, instrumentation and methods for use in agriculture, industry and medicine · 2022 · PMID 35063871

Review

“Sodium citrate also presents radiological properties close to soft tissue. Therefore, considering all properties, in the set of the new materials studied in this work, sodium citrate is a promising material for ESR dosimetry.”

Rech et al. · From the abstract

Names both Lithium and Potassium in its title.

Potassium supplementation in lithium patients: a timely intervention or premature speculation?

The Journal of clinical psychiatry · 1992 · PMID 1429477

ReviewHuman subjects

“Hypokalemia should be avoided or corrected in patients taking lithium. The role of potassium supplementation in preventing renal and other complications in the presence of normokalemia requires further investigation.”

Jefferson · Authors' conclusion

Names both Lithium and Potassium in its title.

Potassium advances circadian activity rhythms: interactions with lithium.

Brain research · 1989 · PMID 2752303

Research Support, U.S. Gov't, Non-P.H.S.Animal study

“These results suggest that lithium's toxic, but not behavioral, actions involve an interaction with potassium ion. Furthermore, dietary potassium supplementation might have independent uses as treatment for chronobiological disorders.”

Klemfuss et al. · From the abstract

Names both Lithium and Potassium in its title.

Safety and Effectiveness of Lithium Therapy in Patients With Graves' Disease.

Clinical endocrinology · 2025 · PMID 40826817

Observational StudyHuman subjects

“Lithium is effective in achieving rapid biochemical control of hyperthyroidism and may serve as a valuable bridging option for patients in whom antithyroid therapy is contraindicated or not tolerated. However, the potential for early renal concentration and calcium metabolism disturbances warrants vigilant monitoring.”

Çavdar et al. · Authors' conclusion

Names Lithium and Potassium together in an interaction, co-administration, or pharmacokinetic context.

Limitations

What this evidence cannot tell you.

Search-based evidence indexes have real limits, and it is worth being explicit about them:

NutriStack

Track what you actually take.

NutriStack is a free iPhone app for organising a supplement routine: what you take, when, and what the published record says about it. Its exploratory interaction checker covers Lithium, Potassium, and several hundred other substances.

The checker is a research and organisation tool, not a clinical decision aid, and its per-pair assessments are excluded from search until they pass claim-level review.
