Amongst other key nutrients, Visisoft containins purified Lutein and Zeaxanthin. Zeaxanthin is one of the two carotenoids (along with Lutein) contained within the retina of the eye. Within the central macula, zeaxanthin is the main component, whereas in the peripheral retina, lutein predominates. Zeaxanthin is one of the most common carotenoids found in nature. It is the pigment that gives paprika (made from bell peppers), corn, saffron, and many other plants their characteristic colour. Visisoft has been featured in The Independent, and also in The Daily Mail as one of their top 5 Eye Care products. Lutein is found naturally in leafy green vegetables and orange-yellow foods such as carrots and sweetcorn, and plays an important role in the health of the retina of the eye, where it helps to protect the delicate light receptor cells from damage by filtering out harmful light. Each Visisoft tablet containing 10mg of purified Lutein plus Zeaxanthin and powerful antioxidants Bilberry and Grape Seed.
