Abstract: Lithium is most well-known for its mood-stabilizing effects in the treatment of bipolar
disorder. Due to its narrow therapeutic window (0.5-1.2 mM serum concentration), there is a stigma
associated with lithium treatment and the adverse effects that can occur at therapeutic doses. However,
several studies have indicated that doses of lithium under the predetermined therapeutic dose
used in bipolar disorder treatment may have beneficial effects not only in the brain but across the
body. Currently, literature shows that low-dose lithium (≤0.5 mM) may be beneficial for cardiovascular,
musculoskeletal, metabolic, and cognitive function, as well as inflammatory and antioxidant
processes of the aging body. There is also some evidence of low-dose lithium exerting a similar and
sometimes synergistic effect on these systems. This review summarizes these findings with a focus
on low-dose lithium’s potential benefits on the aging process and age-related diseases of these systems,
such as cardiovascular disease, osteoporosis, sarcopenia, obesity and type 2 diabetes, Alzheimer’s
disease, and the chronic low-grade inflammatory state known as inflammaging. Although
lithium’s actions have been widely studied in the brain, the study of the potential benefits of lithium,
particularly at a low dose, is still relatively novel. Therefore, this review aims to provide possible
mechanistic insights for future research in this field.
