Some studies have reported an increase in SCFA production following lithium treatment, which could contribute to its therapeutic effects.

Furthermore, lithium has been found to influence bacterial gene expression and metabolic pathways. It can affect bacterial quorum sensing, a communication mechanism that regulates bacterial population behavior. This interaction may have implications for bacterial virulence and biofilm formation, potentially impacting host-microbe interactions.

The bidirectional nature of the lithium-microbiome interaction is also becoming apparent. While lithium affects the microbiome, the gut microbiota may, in turn, influence lithium's pharmacokinetics and bioavailability. Some bacterial species have been found to metabolize lithium, potentially affecting its absorption and distribution in the body.

Recent research has also explored the potential role of the microbiome in mediating some of lithium's known side effects, such as weight gain and metabolic disturbances. Changes in the gut microbial composition induced by lithium may contribute to these effects, possibly through alterations in energy harvest and metabolic signaling.

While our understanding of lithium-microbiome interactions has grown significantly, many questions remain unanswered. The specific mechanisms by which lithium induces these microbial changes, the long-term consequences of these alterations, and their clinical relevance are areas that require further investigation.

The research on microbiome alterations induced by lithium orotate supplementation is in its early stages, indicating an emerging field with significant growth potential.
