Bioactivities and Health Benefits
Antioxidant effects:
Resveratrol has a powerful antioxidant ability to scavenge free radicals, reduce cell damage from oxidative stress and slow down the aging process.
Anti-inflammatory effects:
It can inhibit the production of inflammatory factors and reduce the inflammatory response, which has potential therapeutic effects on chronic inflammatory diseases (e.g. arthritis, cardiovascular diseases).
Cardiovascular protection:
Resveratrol can lower blood lipids, inhibit platelet aggregation and improve vascular endothelial function, thus reducing the risk of cardiovascular disease.
Neuroprotection:
Resveratrol may protect nerve cells through antioxidant and anti-inflammatory mechanisms, slowing down the progression of neurodegenerative diseases (e.g. Alzheimer’s disease, Parkinson’s disease).
Regulation of glucose metabolism:
It may have potential therapeutic effects on diabetes and its complications by activating signaling pathways such as AMPK, improving insulin sensitivity and lowering blood glucose levels.
Antibacterial and antiviral:
Resveratrol has an inhibitory effect on certain bacteria and viruses, and may help enhance immune function.
Forms of application
Dietary supplements: Resveratrol is often sold as dietary supplements in the form of capsules and tablets.
Functional foods: Some foods (e.g. grape juice, red wine, peanut products) contain natural resveratrol.
Cosmetics: Resveratrol is also used in anti-aging skin care products for its antioxidant and whitening effects.
