How We Evaluate Forms

FormulaForge classifies supplement forms using a four-tier system based on published bioavailability research:

  • T1 Preferred — Highest bioavailability tier (S1), strongest clinical evidence for efficient absorption.
  • T2 Specialist — High to good bioavailability (S1–S2), appropriate for specific therapeutic goals or population needs.
  • T3 Customer Choice — Moderate to lower bioavailability; included because customer demand warrants availability.
  • T4 Mapped — Mapped to a T1 or T2 preferred form; dose is automatically adjusted for equivalent effect.

Each form’s bioavailability tier (S1–S4) is determined from published absorption studies. We do not expose raw dose conversion ratios or proprietary calculation methodology in public-facing content.
