Functions of Anthocyanins in Elderberry Extract:
1. Antioxidant Activity
Anthocyanins are strong antioxidants, scavenging free radicals like ROS and RNS. They prevent oxidative damage to cells and tissues by neutralizing these radicals, crucial for maintaining cell membrane, DNA, and protein integrity. This helps reduce the risk of lipid peroxidation related to chronic diseases.
2. Anti - inflammatory Effects
Anthocyanins have anti - inflammatory properties, inhibiting the production of pro - inflammatory cytokines such as IL - 1β, IL - 6, and TNF - α. Chronic inflammation causes health issues, and by reducing it, anthocyanins can alleviate symptoms of related conditions like arthritis.
3. Immune - Boosting
These compounds enhance the immune system by stimulating the activity of immune cells such as macrophages and NK cells. This helps the body defend against infections and diseases.
4. Vision - related Benefits
Anthocyanins improve eye blood circulation and protect retinal cells from oxidative damage and blue light. They may prevent or slow AMD and relieve eye strain.
