Vitamin C is an antioxidant found in fruits and vegetables. It supports healthy capillaries, gums, teeth, and cartilage. Vitamin C can be found in virtually every cell in the body, and its concentration is significantly higher in the retina than in the blood. Since the human body does not make vitamin C, it must be consumed as part of the diet.
Zinc is a trace mineral that is found in high concentrations in the eye. It plays a critical role in transporting vitamin A to the retina. Zinc deficiency has been linked to poor night vision and cloudy cataracts. Zinc appears to provide an additive effect of antioxidant protection and helping to promote good visual acuity.
Lutein & Zeaxanthin
Lutein and zeaxanthin are carotenoids that are selectively transported across the BBB and deposited in the macula of the eye. They serve as antioxidants, which help to neutralize free radicals and reduce oxidative stress. Additionally, they serve to help filter out and reduce the damaging effects of high-energy blue light thus also helping to improve visual acuity.
The bilberry fruit is rich in antioxidant anthocyanosides and has been shown to help retain healthy capillaries, including those in the eye and by helping to support the retina. This is especially important to help support eye health but also to deliver nutrients to this highly metabolically active tissue.
