Origin & History
Natural habitat
Luteolin is a naturally occurring flavonoid found in fruits, vegetables, and herbs like celery, parsley, and chamomile. It is extracted from these sources or synthesized for supplements. Luteolin is valued for its antioxidant and anti-inflammatory properties.
“Luteolin has been used in traditional medicine for its anti-inflammatory and neuroprotective properties. It is commonly consumed through a diet rich in fruits and vegetables.”Traditional Medicine
Scientific Research
Research, including animal studies and some human trials, supports luteolin's role in cognitive and cardiovascular health. Emerging evidence suggests benefits for immune modulation.
Preparation & Dosage
Traditional preparation
Typical dosage ranges from 50-200 mg per day. Consult a healthcare provider before use.
Nutritional Profile
- Flavonoid with potent antioxidant and anti-inflammatory properties.
- Found in celery, parsley, and chamomile.
- Bioavailability varies based on food source and preparation.
How It Works
Mechanism of Action
Luteolin inhibits nuclear factor-kappa B (NF-κB) signaling, reducing pro-inflammatory cytokine production in microglia. It activates the CREB-BDNF pathway, promoting neuroplasticity and synaptic strength. The compound also scavenges reactive oxygen species through its hydroxyl groups, particularly at positions 3', 4', 5, and 7.
Clinical Evidence
Most luteolin research consists of preclinical studies in animal models and cell cultures. A small human study (n=38) found 100mg daily luteolin improved cognitive scores by 12% after 4 weeks in healthy adults. Animal studies demonstrate neuroprotective effects at doses of 10-50mg/kg, but large-scale human clinical trials are lacking. Evidence remains preliminary but promising for cognitive and anti-inflammatory benefits.
Safety & Interactions
Luteolin appears generally safe with no serious adverse effects reported in human studies. It may interact with cytochrome P450 enzymes, potentially affecting drug metabolism. The compound could enhance anticoagulant effects due to its anti-platelet properties. Pregnant and breastfeeding women should avoid supplementation due to insufficient safety data.

Frequently Asked Questions
What foods contain luteolin naturally?
Celery, parsley, and artichokes contain the highest luteolin concentrations at 10-50mg per 100g. Other sources include broccoli, green peppers, and chamomile tea, though in lower amounts.
How much luteolin should I take daily?
Human studies have used 50-100mg daily of luteolin extract safely. Most supplements provide 50mg per capsule, typically taken once daily with food for better absorption.
Can luteolin cross the blood-brain barrier?
Yes, luteolin efficiently crosses the blood-brain barrier due to its lipophilic structure. Studies show brain tissue concentrations reach therapeutic levels within 30 minutes of oral administration.
Does luteolin help with allergies?
Luteolin inhibits mast cell degranulation and histamine release, showing anti-allergic effects in laboratory studies. However, human clinical trials for allergy treatment are limited and more research is needed.
What's the difference between luteolin and quercetin?
Both are flavonoids, but luteolin has superior blood-brain barrier penetration and stronger anti-neuroinflammatory effects. Quercetin has broader antioxidant activity but lower brain bioavailability compared to luteolin.
Does luteolin interact with common medications?
Luteolin may interact with blood-thinning medications like warfarin due to its anticoagulant properties, requiring medical supervision if combined. It can also affect the metabolism of certain drugs through cytochrome P450 enzymes, potentially altering medication efficacy. Always consult your healthcare provider before combining luteolin supplements with prescription medications to avoid adverse interactions.
What is the most bioavailable form of luteolin supplement?
Luteolin glycosides (bound to sugars) and micronized forms generally exhibit better absorption than free aglycone luteolin, though bioavailability remains relatively low at 2-5% in humans. Combining luteolin with fat sources or taking it with foods high in lipids can enhance absorption through the lymphatic system. Liposomal or nanoparticle formulations are emerging options that may improve bioavailability, though clinical data on these forms remains limited.
Who benefits most from luteolin supplementation?
Individuals experiencing cognitive decline, chronic neuroinflammation, or age-related memory issues may benefit most from luteolin's neuroprotective effects. People with elevated LDL cholesterol, cardiovascular risk factors, or those seeking antioxidant support are also prime candidates for supplementation. Athletes and individuals exposed to high oxidative stress environments may benefit from luteolin's potent free-radical-scavenging properties to support recovery and cellular health.
