Hydroxytyrosol improves metabolic health in non-alcoholic fatty liver disease (NAFLD) and obesity by activating transcription factors (PPAR-α, Nrf2), inhibiting lipogenesis, and reducing hepatic inflammation and oxidative stress.
Hydroxytyrosol may support liver health and metabolic function, particularly in the context of a high-fat diet, by reducing inflammation and fat accumulation. While promising in animal studies, human data is still emerging. Focus on a balanced diet rich in olive oil for best results.
ModerateSupportsMEDIUM confidence
HTyr significantly improves metabolic impairments induced by HFD [73,74]. HTyr prevents early inflammatory events responsible for the onset of insulin resistance and steatosis, by reducing the hepatic inflammation and nitrosative/oxidative stress and restoring glucose homeostasis and intestinal barrier integrity [73].
Why this rating
Strong animal model evidence, limited human clinical trials.

More from this paper
- Hydroxytyrosol (HTyr) and its derivatives provide cardioprotective benefits by protecting LDL from oxidation, with a specific health claim established by the European Food Safety Authority (EFSA) requiring a daily intake of 20g of olive oil containing at least 5mg of HTyr and derivatives.Good
- Hydroxytyrosol exhibits significant anticancer effects against various cancer cell lines (colon, breast, prostate, etc.) by inducing apoptosis and inhibiting proliferation, primarily through ROS generation and modulation of signaling pathways like PI3K/Akt/FOXO3a and NF-κB.Moderate
