White Plains, New York, August 23, 2017 — As a prescription medication, the mineral lithium is used to treat bipolar disease and other mood disorders, but some may be surprised to learn that lithium is also sold as a dietary supplement — although in much lower doses than provided by medications. But do low-dose lithium supplements on the market really contain what they claim, and can they really improve mood? To find out, purchased and tested popular low-dose lithium supplements sold in the U.S., and carefully reviewed the clinical evidence.

The tests revealed that one product contained less lithium than listed on the label. Most of the selected supplements, which included lithium in capsule, tablet and liquid forms, contained their claimed amount of lithium, and passed's other tests of quality. However, the dose of lithium and cost of products varied widely: suggested daily serving sizes ranged from 0.05 mg to as much as 20 mg and the cost to get an equivalent amount of lithium ranged from just 8 cents to over $11.

In's Low-Dose Lithium Supplements Review we identify our Top Picks among the products we Approved for quality.
