Luteolin Capsules, graded Emerging-evidence on Magellan — a chlorogenic acid plus luteolin nutraceutical improved weight, glycemic and vascular markers over six months in pre-obesity. Oral bioavailability is poor and the mast-cell/neuroinflammation promise remains largely preclinical. Magellan links 21 peer-reviewed citations for Luteolin Capsules.

Luteolin is a naturally occurring flavone (a class of flavonoid) found in celery, parsley, green pepper, chamomile and various other fruits, vegetables and medicinal herbs. In laboratory and animal studies it acts mainly as an antioxidant and anti-inflammatory agent, inhibiting microglial and astrocyte activation and the release of pro-inflammatory cytokines such as TNF-α, IL-1β and IL-6, and it can modulate endoplasmic reticulum (ER) stress and signaling pathways including JNK/AP-1, NF-κB and mTOR. Because it is poorly water-soluble, luteolin has limited oral bioavailability, so it is often delivered in lipid-based or co-micronized formulations (for example combined with palmitoylethanolamide, PEA) to improve absorption.
Preclinical studies consistently show that luteolin reduces neuroinflammation and can ameliorate memory and learning deficits in rodent models of Alzheimer's disease, cerebral hypoperfusion and LPS-induced cognitive impairment, in part by inhibiting ER stress and cytokine release. Human evidence is more limited and often uses luteolin combined with other agents: randomized trials of palmitoylethanolamide-luteolin (PEA-LUT) plus olfactory training markedly improved recovery of smell after COVID-19 (in one multicenter trial about 89% of patients improved versus 37% with training alone) and reported benefits for subjective cognition; a chlorogenic acid plus luteolin nutraceutical improved weight, glycemic and vascular markers over six months in pre-obesity; and open-label studies of a luteolin-containing formulation in children with autism reported behavioral improvement and lower serum TNF/IL-6. On the other hand, a placebo-controlled trial in Gulf War Illness found luteolin no better than placebo. Overall the data support an anti-neuroinflammatory mechanism with promising but indication-specific, not yet definitive clinical benefit; standalone luteolin is not an established anti-aging supplement, and larger rigorous trials are needed. This evidence describes the compound luteolin (and its formulations) and its mechanisms, not this specific commercial product.
Peer-reviewed studies on the active compound — citations link to PubMed.
“Luteolin alleviates cognitive impairment via inhibiting neuroinflammation”
“a diet supplemented with luteolin inhibited brain microglia activity during aging”
“luteolin can suppress neuroinflammatory response, microglia activation, and oxidative stress”
“The data reviewed strongly support luteolin's promising benefits in pain management and raise the need for further clinical trials that can establish its role in clinical practice.”
“luteolin prevented the increase of TNF-α and IL-1β, IL-6, and MDA, improved the activity of SOD and GPx, inhibited microglia over-activation and astrogliosis (particularly in the hippocampus and cortex), and ameliorated learning and short-term memory dysfunction, and LTP deficit.”
“Luteolin (100 mg/kg/d) combined with exercise could significantly improve the performance of AD model mice in novel object recognition test, and the improvement was greater than that of monotherapy.”
