How to Choose the Right Sleep Support Supplement

  • Prioritize bioavailability tier. "Best Absorption" and "High Absorption" forms are absorbed most efficiently. Our formulary ranks every ingredient by absorption research so you can select the most effective form.
  • Check formulary tier. T1 Preferred ingredients represent the best-researched, highest-bioavailability forms. T2 Secondary options are strong alternatives with specialized use cases.
  • Look for third-party testing. Supplements are not FDA-approved prior to sale. Choose products with independent certificate of analysis (CoA) testing for purity and potency verification.
  • Consult your healthcare provider. Individual needs vary based on health status, diet, medications, and genetics. A qualified healthcare provider can help determine which supplements are appropriate for your situation.
