Why Pterostilbene Form Matters

Not all forms of Pterostilbene are created equal. There are 1 forms available in our database. All available forms are classified at the same formulary tier, though individual bioavailability data may still vary.

Choosing the right form means getting more benefit from every dose. FormulaForge uses proprietary bioavailability data to rank forms and recommend the most effective options for each individual.

Our Rankings

Forms are ranked by formulary tier, which reflects relative bioavailability and clinical evidence quality. Lower tier number = higher preference.

  1. #1 — Pterostilbene (Preferred Form): bioavailability rated high absorption. This is our research-backed preferred form.

How We Evaluate Forms

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

  • Preferred Form — Highest absorption, strongest clinical evidence for efficient absorption.
  • Secondary Form — High to good absorption, appropriate for specific therapeutic goals or population needs.
  • Customer Choice — Moderate to lower bioavailability; included because customer demand warrants availability.
  • Mapped Form — Mapped to a Preferred or Secondary form; dose is automatically adjusted for equivalent effect.

Each form’s absorption rating is determined from published absorption studies. We do not expose raw dose conversion ratios or proprietary calculation methodology in public-facing content.

How We Rank Supplement Forms

FormulaForge ranks supplement forms using a proprietary four-tier system based on bioavailability research:

  • Preferred Form — Top Form Score (~95/100 and above). Best-researched, most efficiently absorbed form.
  • Secondary Form — High Form Score (~80/100 and above). Strong research support, may serve specialized uses.
  • Customer Choice — Moderate evidence. Available by request with informed consent.
  • Mapped Form — Lower bioavailability. Mapped to higher-quality alternatives with dose conversion guidance.

Each form receives a 100-point Form Score derived from peer-reviewed absorption studies. FormulaForge's rankings are reviewed by Dr. Brennan Commerford, D.C.
