• Formula of one capsule a day.• Providing 20 mg of lutein of natural origin in "free form", ready to be absorbed.• Also includes zeaxanthin.• Provides 356 mg of omega 3 per capsule, including 250 mg of DHA that 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 value of reference nutrients for adults. This new formula is unique and comes in the form of One a Day. It is also a synergistic combination of omega 3 fatty acids, with lutein, zeaxanthin and natural vitamin D3 As with our successful original Eyewise® , available in our range, we have included zeaxanthin, as well as 20mg of pure lutein in "free form", which is ready to be absorbed. Lutein and zeaxanthin are carotenoids that are not produced in the body Therefore, they must be obtained from the diet, especially from green leafy vegetables. In plants, lutein is produced to protect cell contents from damage by sunlight. 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 damage the delicate light-receptor cells of the macula. Like all carotenoids, lutein is an antioxidant and therefore may play a role in protecting macular tissue against damage caused by damaging free radicals. Moreover, numerous studies indicate that omega-3 fatty acids may also be especially important in preserving and maintaining healthy eyes, especially as we age. Therefore, we have 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 is produced a under the strict GMP (Good Manufacturing Practice) manufacturing regulations, which are rigorously controlled by the Medicines Control Agency of the Department of Health of the United Kingdom. It is increasingly recognized that vitamin D is important for much more than the bone health. Also, there is emerging evidence in clinical research linking vitamin D to ocular well-being. Eyewise® Omega 3 provides natural vitamin D3 at 100% of the nutrient reference value (NRV) for adults. Vitamin D is also essential for bones and can slow the progression of osteoporosis, strengthen the immune system and help fight some health disorders. There are many studies that support the argument that we should all watch 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 aged 60 and over. This benefit is achieved with a daily dose of 20 µg per day.
