• One a day formula.• Providing 20 mg of naturally sourced lutein in “free form,” ready to be absorbed.• Also includes zeaxanthin.• Provides 356 mg of omega-3 per capsule, including 250 mg of DHA which contributes to the maintenance of normal vision.• The pure fish oil we use is made with the same rigorous quality and purity controls as all our fish oils and is certified from sustainable fisheries.• Natural vitamin D3 at 100% of the Nutrient Reference Value for adults.This new One a Day formula is unique and comes in a synergistic combination of omega-3 fatty acids, with lutein, zeaxanthin, and natural vitamin D3.As with our successful original Eyewise® range, we have included zeaxanthin, as well as 20 mg of pure “free form” lutein, which is ready to be absorbed.Lutein and zeaxanthin are Carotenoids are not produced in the body and must therefore be obtained from the diet, especially from green leafy vegetables. In plants, lutein is produced to protect cellular contents from sunlight damage. Our bodies can use lutein in the same way when it is deposited in the macula, where it filters out harmful wavelengths of sunlight that can harm the delicate light-receptor cells in the macula. Like all carotenoids, lutein is an antioxidant and therefore may play a role in protecting macular tissue from damage caused by harmful free radicals. Furthermore, numerous studies indicate that omega-3 fatty acids may also be especially important in preserving and maintaining healthy eyes, especially as we age. That's why we've included a total of 356 mg of omega-3 per capsule, providing 250 mg of DHA, which contributes to the maintenance of normal vision. In addition, the pure fish oil we use is highly certified from sustainable fisheries and produced under strict GMP (Good Manufacturing Practice) manufacturing standards, which are rigorously controlled by the UK Department of Health's Medicines Control Agency. It's becoming increasingly recognized that vitamin D is important for much more than bone health. There is also emerging evidence from clinical research that links vitamin D to eye health. Eyewise® Omega 3 provides natural vitamin D3 at 100% of the Nutrient Reference Intake (NRV) for adults. Vitamin D is also essential for bone health and may slow the progression of osteoporosis, strengthen the immune system, and help combat some health disorders. There are many studies that support the argument that we should all monitor our vitamin D intake. Vitamin D helps reduce the risk of falls related to postural instability and muscle weakness. Falls are a risk factor for bone fractures in men and women over 60 years of age. This benefit is achieved with a daily dose of 20 µg.
