Reported Benefits (Provisional)

Supports eye health by improving night vision and reducing eye fatigue, enhancing visual performance. - Rich in antioxidants, bilberry protects retinal cells from oxidative damage, preserving eye health. - May improve blood sugar levels by enhancing insulin sensitivity, which can benefit those with diabetes. - Supports cardiovascular health by improving blood vessel strength and reducing blood pressure. - Enhances cognitive function by increasing blood flow to the brain, potentially reducing the risk of cognitive decline. - Contains anti-inflammatory properties that can help reduce symptoms of chronic inflammatory conditions. - Aids in reducing swelling and bruising by improving circulation and capillary strength.

Origin & History

Bilberries are native to Europe and closely related to blueberries. The extract is standardized to 25% anthocyanins, known for their antioxidant properties.

“Bilberries have been used in traditional European medicine for their health benefits, particularly in supporting eye health.”Traditional Medicine

Research Narrative (Provisional)

Studies suggest bilberry extract can improve vision and support cardiovascular health due to its high anthocyanin content. More research is needed to confirm these benefits.

Nutritional Profile

- High in anthocyanins, a potent antioxidant. - Contains vitamin C and dietary fiber. - Low in calories and free from fat.

Reported Mechanism (Provisional)

Mechanism of Action

Bilberry anthocyanins, primarily delphinidin and cyanidin glycosides, enhance rhodopsin regeneration in retinal photoreceptor cells, improving light adaptation. These compounds also stabilize collagen in blood vessel walls by inhibiting elastase and hyaluronidase enzymes. Additionally, anthocyanins activate the PI3K/Akt pathway, enhancing insulin sensitivity and glucose uptake in peripheral tissues.

Clinical Narrative (Provisional)

Human studies with bilberry extract (25% anthocyanins, 160-480mg daily) show significant improvements in night vision adaptation and reduced eye fatigue in 4-12 week trials with 20-100 participants. A randomized controlled trial found 25% reduction in eye strain symptoms among computer users taking 160mg daily for 8 weeks. Limited evidence suggests modest improvements in blood glucose control, though larger studies are needed. Most research focuses on short-term visual benefits rather than long-term eye health outcomes.
