Luteolin
Antioxidant ·Exploratory record · not publication-reviewed ·Updated July 13, 2026
Luteolin is a plant-derived flavone found in many fruits, vegetables, and herbs that has antioxidant, anti-inflammatory, and mast-cell-stabilizing properties. It is marketed for cognitive and immune support, often combined with related flavonoids such as quercetin or rutin to improve its otherwise modest oral bioavailability.

What the research says.
A quick, data-only summary. The full evidence, dosing, and sources are below.
Luteolin is an antioxidant most often used for antioxidant and free-radical scavenging support, anti-inflammatory effects, mast-cell stabilization and allergy/histamine support. NutriStack rates the overall evidence as emerging. A typical adult dose is 100-300 mg per day, often divided; some formulations combine it with quercetin or rutin, commonly taken as liposomal or lipid-based luteolin (or luteolin combined with quercetin/rutin) to improve absorption. This profile indexes 9 sources.
- Generally well tolerated at typical doses
- Mild gastrointestinal upset
- Nausea
- Pregnancy and breastfeeding (insufficient safety data)
- Use with caution alongside medications metabolized by CYP enzymes due to potential interactions4
The bottom line
Evidence rating emerging. Most-documented uses: antioxidant and free-radical scavenging support, anti-inflammatory effects, mast-cell stabilization and allergy/histamine support. 9 sources indexed (1998–2015), with 0 interaction records on file.
How it works, mechanistically.
Core mechanism
Luteolin acts through several overlapping pathways. As a polyphenol it scavenges reactive oxygen species and activates the Nrf2/ARE antioxidant response, while also inhibiting pro-inflammatory signaling by suppressing NF-kB activation and reducing production of cytokines such as TNF-alpha, IL-6, and IL-1beta. It stabilizes mast cells and basophils, limiting the release of histamine and other mediators, and modulates microglial activation in the central nervous system, which underlies its investigational role in neuroinflammation. Luteolin can also inhibit certain enzymes (including phosphodiesterases and select cytochrome P450 isoforms) and has been reported to influence kinase signaling pathways relevant to cell proliferation in preclinical models.1,2
Dosing & protocol.
Luteolin has low aqueous solubility and modest oral bioavailability; taking it with a fat-containing meal or using liposomal/micellar formulations can improve uptake. It is extensively metabolized to glucuronide and sulfate conjugates.
What it actually costs.
Real-world pricing across three quality tiers. Assumes Free aglycone capsule/powder.
Per-dose pricing assumes a ~100-200 mg effective daily dose. Plain luteolin powder and quercetin-luteolin blends are cheapest; liposomal/phytosome forms and standardized perilla extracts command a premium. Isolated luteolin generally costs more than common flavonoids like quercetin due to lower production volume. Updated 2026-06-04.
