Direct answer

Alpha-Lipoic Acid can be sold in the United States as a supplement or cosmetic ingredient. Its legal category is "Sold as a dietary 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, 1 completed human trial is 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

    Alpha-Lipoic Acid 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.

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 Alpha-Lipoic Acid 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.

Alpha-Lipoic Acid in sport and the military

Whether Alpha-Lipoic Acid 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 Alpha-Lipoic Acid 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.

The rules you compete or serve under decide this, not this page.
