Is Low-dose lithium legal in the United States?
Written by Aaron CuhaReviewed Sep 2026
Direct answer
Low-dose lithium can be sold in the United States as a supplement or cosmetic ingredient. Its legal category is "Sold as a supplement". That is not approval as a drug. FDA has not checked any health claim made for it. Versions you inject, and "research use only" versions, fall outside supplement rules, so that label does not make them legal to use in people. On the evidence, 3 completed human trials are cited on its profile.

A "research use only" label on a vial does not make it legal to use on people.

What this means
- 01
Low-dose lithium can be sold in the United States as a supplement, food or cosmetic ingredient, under the legal category above. It has no approval as a drug.
- 02
Being sold as a supplement means FDA has not checked any health claim. The makers are responsible for safety and labels, and quality varies from product to product.
- 03
Versions you inject, and "research use only" versions, are not supplements. That label does not make them legal to use in people, and anything you inject falls under the rules for medicines.
What Low-dose lithium is
The tap water studies people quote are not tests on people. A review pooled 15 studies that compared lithium in local water with local suicide rates. Places with more lithium had fewer suicides, but the authors warn that patterns across places may not apply to people. The studies that actually gave people lithium used prescription lithium carbonate at 150 to 600 mg, adjusted by blood test. That is a different thing from the few milligrams of lithium orotate sold in shops.
Low-dose lithium is a whole product category built on a kind of study that cannot support it. And the real tests in people used a different dose of a different form.
How it works: Lithium blocks an enzyme called GSK3 beta. That enzyme sits upstream of tau build-up and of how amyloid is made, two hallmarks of Alzheimer's disease.
Approval history: Lithium carbonate and lithium citrate are FDA-approved prescription medicines for bipolar disorder. People taking them must have regular blood tests to check their lithium level. Lithium orotate is sold as a dietary supplement. It has no approved use and no required blood tests.
How FDA treats this kind of product
Approves prescription drugs, each for a named use. It also acts against unapproved products, including peptides sold online. Compounding pharmacies, which mix drugs to order, may make some compounds with a prescription. That only applies when the FDA puts the compound in a category of bulk ingredients it allows.
The legal category above is how The Longevity Archive reads U.S. Food and Drug Administration listings for Low-dose lithium on the reviewed date. It is not a legal opinion. Rules change. Bringing a compound into the country, prescribing it and owning it can each be treated differently. Check with the agency before you act on anything here.
Low-dose lithium in sport and the military
Whether Low-dose lithium is banned in sport is set by the World Anti-Doping Code and by military rules, not by its legal status in the United States. Before you compete or get tested, look up Low-dose lithium by name on the Prohibited List, or look up a named product in Global DRO. Under the World Anti-Doping Code, category S0 bans, at all times, any drug-like substance that meets two tests. No other section of the List covers it. And no government health regulator anywhere has a current approval for it as a treatment in people. Many substances that are approved somewhere are banned by name in another section. So approval does not mean a substance is allowed in sport.
