Vicenin-1 is a flavonoid compound with multiple biological activities, particularly as an antioxidant that protects cells from free radical damage. It is used in cosmetics to shield skin from oxidative stress, environmental damage, irritation, and to promote anti-aging effects.

In dietary supplements, it shows potential due to anti-inflammatory properties and its ability to help regulate blood sugar levels, making it suitable for supporting individuals with high blood sugar. Research indicates antiviral effects in laboratory settings, which could lead to future antiviral drug development.

It is studied for supporting cardiovascular health by improving vascular function and for possible anticancer activity, especially in inhibiting tumor cell proliferation. Vicenin-1 is also explored in functional foods for its natural bioactive profile, often derived from traditional herbal plants.
