Tangeretin is widely used in the pharmaceutical and nutraceutical industries due to its strong biological activities. It exhibits anti-inflammatory and antioxidant properties, making it valuable in formulations aimed at reducing oxidative stress and chronic inflammation. Research supports its potential in cancer prevention, as it has shown ability to inhibit the growth of various cancer cell lines, including those of the breast, colon, and liver, by inducing cell cycle arrest and apoptosis. It is also studied for its neuroprotective effects, with evidence suggesting it may help in managing neurodegenerative disorders like Alzheimer’s disease by reducing amyloid-beta plaque formation and improving cognitive function. In skincare products, tangeretin is used for its anti-aging and UV-protective effects, thanks to its capacity to neutralize free radicals and protect skin cells from photo-damage. Additionally, it has been explored for its role in metabolic health, showing potential in improving insulin sensitivity and lipid metabolism, which could benefit conditions like diabetes and obesity. Its natural origin and low toxicity profile make it a favorable ingredient in functional foods and dietary supplements.
