Stem cell supplements (oral)
Tier 3 — weak evidence · Anti-aging · Regenerative · Unproven
Various products marketed as oral stem cell activators, stem cell nutrition, or plant stem cells. There is zero evidence that any oral supplement activates stem cells in the human body. Plant stem cells are completely non-functional in human tissue. "Stem cell activator" supplements contain ordinary antioxidants rebranded with misleading names. FTC has issued warnings against false stem cell product claims.
Dose: No evidence-based dose; these products have no scientific basis; FTC has warned against fraudulent stem cell claims
