Caring for vision becomes increasingly critical with age. Studies have shown that eating a healthy, balanced diet is important for your health, yet we know it is not always possible to eat a balanced diet. PreserVision Lutein Softgels is based on a formulation which was developed in conjunction with the National Eye Institute (NEI) in the USA. PreserVision Lutein Softgels contains lutein which is found naturally in the body, at the back of your eye in the macula. PreserVision Lutein Softgels is also rich in zinc, a mineral which supports normal vision and helps protect cells from oxidative stress. Oxidation is a normal part of ageing but certain behaviours, such as smoking can speed up the oxidative process.
