Is stem cell therapy legal in the United States?

P Written by: Phil Kim Medically reviewed by: Dr. Robert Aki, DPM Last medically reviewed: October 9, 2026

Yes, stem cell therapy is legal in the United States. What is unlawful is marketing specific unapproved stem cell or exosome products as treatments outside of a clinical trial. The FDA has approved blood-forming stem cell products for certain serious blood disorders, and most cell-based and PRP treatments offered for joint pain remain investigational. A trustworthy clinic, like ours, explains this plainly.

What the law actually says

Stem cell therapy is not illegal in the United States. What is unlawful is marketing specific unapproved products as treatments outside of a clinical trial. The FDA has approved blood-forming stem cell products derived from cord blood for certain serious blood disorders, and certain uses of a patient's own cells within the same surgical procedure are allowed.

The real question is never whether stem cells are legal. It is whether the specific product a clinic is selling has been approved or studied for what it claims to do.

Why the confusion exists

Marketing blurs the line. The FDA regulates stem cell products as drugs and biological products, which means they generally need premarket approval before they can be lawfully marketed. Most cell-based products marketed for joint pain and other conditions have not been cleared for those uses, and facility registration is not the same as product approval.

What to ask a clinic

  • Is this treatment FDA-approved for my condition, and if not, does the clinic say so clearly?
  • Is this treatment part of a registered clinical trial?
  • Where do the cells come from, and who prepares them?
  • Can I see published evidence for this exact treatment for my condition?
