Why SunActive®-IsoQ (Isoquercitrin) Form Matters
Not all forms of SunActive®-IsoQ (Isoquercitrin) 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 — SunActive®-IsoQ (Isoquercitrin) (Preferred Form): bioavailability rated good (S2), typical dose range not yet documented in our database. 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 bioavailability tier (S1), strongest clinical evidence for efficient absorption.
- Secondary Form — High to good bioavailability (S1–S2), 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 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.
