Key findings

  • Reviews betaine sources, synthesis, extraction and proposed health mechanisms, especially from animal research.
  • The recorded outcome domains were Betaine biology; Clinical and mechanistic evidence.

What this study can and cannot tell us

  • A broad narrative synthesis; direct human efficacy and long-term dosing questions remain unresolved.
  • The conclusions inherit the limitations of the underlying studies. A narrative interpretation or guideline recommendation is not a new randomized treatment comparison.
  • Source basis: Accessible full-text extract plus indexed bibliographic data. Missing method details, funding information or participant denominators are not inferred.
