Eriodictyol is widely used for its strong antioxidant properties, helping to neutralize free radicals and reduce oxidative stress in biological systems. It is incorporated into dietary supplements and functional foods aimed at supporting cardiovascular and metabolic health. Due to its anti-inflammatory effects, eriodictyol is studied for potential use in managing chronic inflammatory conditions such as arthritis and neurodegenerative diseases. It also shows promise in improving skin health and is added to cosmetic formulations to protect against UV damage and slow signs of aging. Additionally, eriodictyol exhibits neuroprotective activity, making it a candidate for research in Alzheimer’s and Parkinson’s diseases. Its ability to modulate cellular signaling pathways further supports its use in promoting overall cellular health and longevity.
