Choosing the right bioflavonoid antioxidant supplement matters: different compounds (quercetin, luteolin, hesperidin, rutin, eriocitrin) and delivery systems produce different effects for immune support, circulation, cognitive health, or gut balance. These recommendations come from lab-spec review of labels, comparative ingredient analysis, consumer feedback, and hands-on testing of formulation, dosing, and claimed delivery technologies.
How we tested and selected products
What we looked for
- Ingredient quality & standardization: Does the product list active compound amounts and standardized extracts (for example, % hesperidin or eriocitrin)?
- Dose and formulation: Total flavonoid dose per serving, synergistic cofactors (vitamin C, piperine), and whether delivery (liposomal, micronized) improves absorption.
- Third-party / brand quality signals: Reputable manufacturing, allergen-free or hypoallergenic formulations, and clear labeling.
- Real-world factors: Price per serving, capsule count, vegetarian/vegan suitability, and user experience (taste, digestibility).

These factors informed the final rankings that balance efficacy, safety, affordability, and convenience.
Budget Luteolin Complex
Affordable luteolin-rutin formula delivering 50 mg luteolin and 50 mg rutin per serving in a vegetarian capsule. Good starter option for users seeking basic flavonoid support on a tight budget; clean ingredient profile and free of common allergens.
Budget Luteolin Complex — Why it made the list
This compact formula supplies luteolin and rutin at modest doses with vegetarian capsules and a clean ingredient profile. It’s ideal for someone testing flavonoids for the first time or managing a tight supplement budget.
- Pros: Very low price, vegetarian, non-GMO and free of common allergens. Easy to incorporate daily.
- Cons: Low per-capsule potency; multiple capsules may be needed for therapeutic doses. No advanced delivery system.
Technical notes: label indicates a 50 mg luteolin + 50 mg rutin blend per serving, making this a sensible maintenance or starter product rather than a high-dose therapeutic option.
Pure Encapsulations Quercetin
High-quality, practitioner-grade quercetin at a clinically meaningful 500 mg serving with hypoallergenic formulation. Backed by a brand known for clean manufacturing and minimal excipients — great for immune and cellular support.
Pure Encapsulations Quercetin — Premium quality and purity
This product stands out for ingredient purity and manufacturing standards. The label lists a 500 mg quercetin serving and Pure Encapsulations’ reputation for hypoallergenic, lab-tested supplements adds confidence for sensitive users and practitioners.
- Pros: Clear potency, practitioner-grade manufacturing, free from unnecessary additives, broad trust from clinicians.
- Cons: Higher price per bottle; single-compound focus (quercetin) means you may need complementary nutrients for synergy such as vitamin C.
Technical details: 120 capsules per bottle and dosing recommended on the label (consult healthcare provider). Best for users prioritizing high-quality quercetin and clean formulations.
High-Strength Citrus Complex
A broad-spectrum citrus bioflavonoid complex delivering 1500 mg per serving (including 50% standardized hesperidin), plus quercetin and rutin. Vegan-friendly and formulated for circulation and antioxidant support at a competitive price.
High-Strength Citrus Complex — Big dose, strong value
This 1500 mg complex pairs high total flavonoid content with a standardized hesperidin concentration (50%), plus quercetin and rutin. It’s an efficient way to get a broad-spectrum flavonoid profile without a premium price tag.
- Pros: High per-serving potency (1500 mg), vegan capsules, standardized hesperidin for circulation support, good price-to-dose ratio.
- Cons: Large serving size may require two capsules; not liposomal so absorption depends on formulation matrix.
Technical notes: Typical serving is two capsules; ingredients are plant-based and free of artificial additives. This is a balanced choice for users wanting strong antioxidant coverage without specialty delivery tech.
Liposomal Luteolin Complex
An 8-in-1 liposomal luteolin formula combining high-potency luteolin with fisetin, PEA, curcuminoids, and liposomal delivery for improved bioavailability. Designed for cognitive and antioxidant support with absorption-optimizing ingredients.
Liposomal Luteolin Complex — Our top pick for performance
This formula uses liposomal delivery, micronization, and complementary actives (fisetin, PEA, curcumin) to boost absorption and broaden benefits beyond a single flavonoid. The high luteolin concentration and multi-actives make it versatile for cognitive and systemic antioxidant support.
- Pros: Liposomal and micronized delivery for potentially better uptake, multi-compound synergy, strong antioxidant profile, vegan-friendly.
- Cons: Complex formulas can be overkill for casual users; source (peanut shell for luteolin) may be a concern for those with severe peanut allergies despite purification claims.
Technical details: Marketed as 1500 mg formula with liposomal tech and several co-actives (fisetin, PEA, turmeric, vitamins) to improve cellular delivery. Recommended for users who want a higher-performance flavonoid product backed by modern delivery methods.
Comparison overview — quick differences
- Liposomal Luteolin Complex (Editors Choice): Best overall for absorption and broad antioxidant/cognitive support thanks to liposomal delivery and multi-actives.
