Best Form of Luteolin (2026)

Evidence-based ranking of 1 form by bioavailability

Quick Answer

What is the best form of Luteolin?

Luteolin shows up in small, inconsistent amounts in foods like celery and parsley — so "luteolin" on a label can mean almost anything unless it specifies a standardized extract.

Luteolin occurs in small, inconsistent amounts in foods like celery and parsley, which makes a defined extract meaningfully different from a food-derived source. FormulaForge's tracked form is a standardized luteolin extract; we don't currently have a specific flavonoid-content percentage or citation on file for it, so this page describes the extract itself rather than a comparison. Our general-use /100 form-grade score for this ingredient isn't goal-specific. There may be a holistic reason to consider a standardized extract like this; talk to your physician.

    Form: Extract

    Luteolin — Luteolin is one form of this compound. The rating above reflects its absorption chemistry only. Limited direct human-PK evidence for this specific form. We grade forms only where form-specific human pharmacokinetic evidence exists; this form does not yet meet that bar, so we do not assign it a benefit rating.

Why Luteolin Form Matters

Not all forms of Luteolin 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 — Luteolin (Preferred Form): bioavailability rated good 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.

Frequently Asked Questions

What is the best form of Luteolin?
Luteolin is the Preferred Form form of Luteolin based on FormulaForge's research-backed formulary assessment. It carries a bioavailability rating of good, indicating superior absorption compared to lower-tier forms. Always consult a qualified healthcare provider before starting, stopping, or adjusting any supplement regimen.
Why does the form of Luteolin matter?
Different chemical forms of Luteolin can vary in how well they are absorbed and used by the body. Our formulary lists 1 form of Luteolin. FormulaForge uses published bioavailability research to classify forms and recommend the most effective options.
How do I choose the right Luteolin supplement?
Choosing the right Luteolin supplement depends on your specific health goals, budget, and any existing conditions or medications. Start by comparing form ratings — Preferred Forms reflect the strongest bioavailability evidence. Review dose ranges documented for each form, and confirm the choice with your healthcare provider. Always consult a qualified healthcare provider before starting, stopping, or adjusting any supplement regimen.
Is Extract worth the extra cost?
Luteolin is classified as Preferred Form with a bioavailability rating of good. Higher-tier forms may cost more because of the research and manufacturing processes required to achieve better absorption. Whether that trade-off is worthwhile depends on your individual goals, budget, and healthcare provider's advice.
