Lithium orotate
From Free net encyclopedia
Lithium orotate is a type of lithium salt generally sold as an alternative to lithium carbonate. Since lithium orotate is not approved by the FDA for use as a drug in the United States, its proponents market it as an over-the-counter dietary supplement.
The amount of elemental lithium in each tablet are much lower than those in lithium carbonate pills. The lithium is attached to an orotate ion, rather than to a carbonate ion. According to proponents of lithium orotate treatment, this allows the lithium to cross the blood-brain barrier more effectively, and significantly reduces the amount of lithium required in order for the lithium to have a therapeutic effect for use in combating depression and stabilizing bipolar moods. Lithium orotate is sometimes sold as "organic lithium" by nutritionists, as well as under a wide variety of brand names. The type of ion which it is attached to makes it different than lithium carbonate.
There seems to be little evidence for the use of lithium orotate in clinical treatment in preference to lithium carbonate, and some suggest that it may be harmful. Nevertheless, some patients use it in place of lithium carbonate, as they believe that side effects tend to be significantly reduced.
An animal study by Smith and Schou suggests that the kidneys clear lithium orotate significantly less effectively than lithium carbonate, and that this accounts for the higher serum levels of lithum when lithium orotate is taken compared to the equivalent amount of lithium carbonate. They conclude: "The higher lithium concentrations could be accounted for by the lower kidney function. It seems inadvisable to use lithium orotate for the treatment of patients."
It should be noted that self-treatment of a psychiatric disorder without medical monitoring is potentially dangerous.
