Lithium itself is the active ingredient that influences many brain and body processes, with its biological effects ultimately arising from the lithium ion (Li⁺).
So why not simply take elemental lithium? Why take lithium orotate?
Elemental lithium is highly chemically reactive, readily interacting with air and moisture. When exposed to water, including bodily fluids, lithium rapidly forms lithium compounds while releasing heat and hydrogen gas. Because of this reactivity, lithium metal is unstable during storage and impractical for tablet manufacturing, making it incompatible with the requirements for safe, standardized dosing. If ingested, elemental lithium would react immediately with gastric fluids to form lithium hydroxide, a caustic alkaline compound capable of irritating or damaging gastrointestinal tissues. This rapid, uncontrolled reaction would also result in unpredictable lithium ion exposure, preventing reliable absorption or dosing.
Pairing lithium with another molecule solves these challenges, which is a common pharmaceutical strategy used to improve stability, manufacturability, and dissolution characteristics.
When lithium is combined with carbonate, citrate, orotate, or other counter-ions, it forms a stable crystalline salt that can be safely manufactured, stored, handled, ingested, digested, and absorbed in a gradual and predictable manner. In this sense, lithium salts such as lithium carbonate or lithium orotate act as practical "delivery system" for the Li⁺ ion to ultimately get into the body to function.
While all lithium salts ultimately provide the same lithium ion, the molecule paired with lithium can influence properties such as stability, solubility, and tolerability.
