Bilberry, Lutein and Zinc: What Is in Our Bilberry Multi

Modern life demands that many of us spend hours each day staring at screens. Whether for work, study, or leisure, this prolonged exposure to digital devices places consistent demands on the eyes. Zinc contributes to the maintenance of normal vision. Among the most researched nutrients for eye health are bilberry, lutein, and zeaxanthin, alongside key mineral cofactors like zinc and selenium.

Lutein and zeaxanthin are yellow pigments found in the eye and in green vegetables. It is important to note that no nutrient can entirely block blue light or reverse changes associated with ageing, but a diet rich in these compounds may contribute to long-term visual comfort.

Bilberry, a close relative of the blueberry, has been used traditionally in Europe for various aspects of wellness. The fruit is particularly noted for its high concentration of anthocyanins, the pigments responsible for its deep purple colour. These compounds are associated with antioxidant activity, which may help protect cells from oxidative stress. Bilberry is a European berry related to the blueberry, rich in anthocyanin pigments. As with all botanicals, bilberry is best viewed as part of a broader nutritional strategy rather than a standalone remedy.

Lutein and zeaxanthin are carotenoids that accumulate specifically in the macula. The body cannot produce them, so they must come from the diet or supplementation. Zinc contributes to the maintenance of normal vision; our Bilberry Multi gives 5 mg zinc (50% NRV) per capsule. Observational studies have linked higher dietary intakes of these carotenoids with better visual function in later life.

While lutein and bilberry often receive the most attention, mineral cofactors are equally important. Zinc is concentrated in the retina, where it plays a role in the metabolism of vitamin A, a nutrient essential for night vision. Zinc also contributes to the normal function of the immune system. Selenium contributes to the protection of cells from oxidative stress; our Bilberry Multi gives 55 µg (100% NRV) per capsule. A well-formulated supplement will often include these minerals in carefully measured amounts to complement the primary nutrients.

No single nutrient can compensate for poor screen habits, but take regular screen breaks (the 20-20-20 rule). Alongside regular breaks, proper lighting, and the 20-20-20 rule—looking at something 20 feet away for 20 seconds every 20 minutes—nutritional support becomes a practical part of a broader eye-care routine. Our Bilberry Multi label says this product should be avoided during pregnancy, breastfeeding and if you take medication, unless advised by a medical practitioner. The goal is not to claim dramatic results, but to provide the body with the tools it needs to maintain normal visual function in the face of modern demands.
