Bilberry extract

Tier 2 — promising · Eye health · Circulation · Antioxidant

Rich in anthocyanins and studied for eye fatigue, night vision, and circulation. Several small trials show modest improvements in screen-related visual fatigue and eye dryness. Night vision evidence is mixed and based largely on older studies. Very safe with no significant drug interactions and a long history of use in European herbal medicine.

Dose: 80–480 mg/day standardised to 25% anthocyanins; best studied for eye fatigue and dryness
