Luteina 30 capsules

We know of over 600 different types of naturally-occurring carotenoids, only twenty of which are related to the eyes (vision). Of these, lutein (together with zeaxanthin) is the only carotenoid that is deposited in large quantities in the macular portion of the eye. Unsurprisingly, it is well-known amongst ophthalmologists a natural “friend” and protector of eye health. Together with zeaxanthin (another carotenoid), it composes the pigment present in the area of the retina in which the image is formed (the “macula”). Estimates show that over 25 million people worldwide are affected by macular degeneration and cataracts due to age, especially subjects over 50-55 living in western industrialised nations. According to data from the American Optometric Association, the incidence of this pathology is expected to triple by the year 2025. Lutein protects our eyes by filtering a percentage of harmful UV short waves that negatively affect delicate parts of the eyes, such as the retina. Researchers at Harvard University have discovered that taking 6 milligrams of lutein a day reduces the risk of macular degeneration by 43%. Its use as a nutritional supplement for this purpose is widespread, and several studies have shown that increased lutein and zeaxanthin intake are associated with a significant reduction in the risk of cataract formation. Although research is still at an early stage, it has been shown that taking lutein achieves an improvement in vision in the elderly already suffering from this disorder. Another significant benefit of lutein for our vision is the reduction of eye fatigue and sensitivity to light, helping to maintain appropriate retina and lens density, strengthen eye tissue and helping eyesight to be more acute.

Especially when associated with zeaxanthin, lutein is deposited on the macula of the eye, protecting it from harmful radiation and ultraviolet rays. Lutein deficiency can cause other diseases or disorders such as age-related macular degeneration or cataracts, but also the appearance of conjunctivitis and retinitis pigmentosa. This is because lutein is not only present in the central part of the retina, but also in the crystalline lens, where it counteracts the oxidation responsible for cataracts. In the case of dry eyes or conjunctivitis, lutein can be taken to promote healing and eye protection. The known antioxidant properties of lutein help fight free radical damage caused by ultraviolet rays, sun exposure, an unbalanced diet and diets low in antioxidants, in addition to the other factors already mentioned that increase the risk of developing age-related vision loss or diseases such as macular degeneration and cataracts.

Why are antioxidants also important for eye health? Inside the eyes, one of the most important functions is the collection and focussing of light on the retina, which is precisely why the so-called “lenses” must remain “clear” and unclouded. The main reason why lenses become cloudy is damage from oxidation, which is why we need antioxidants to help neutralise free radicals.

This is not only “preventive”: since nutrients and micronutrients in food can dry up, people with pre-existing eye damage are recommended to introduce lutein to their diet, for instance by taking quality supplements. Therefore, the proper addition of lutein with the support of zeaxanthin can help to counteract the worsening of potential pathological conditions, but it is also an excellent protection of ocular health and a valuable aid in case of visual stress (concentrated work at the computer or fatigue from reading), difficulty with night vision and stress-related difficulties in focusing.

Although lutein is to some extent associated with sight and ocular health, it also has other benefits for the body, such as the prevention of certain skin diseases and type-2 diabetes, and it seems to help counteract the risk factors associated with coronary heart disease.
