Visiochron®

Basics

Age-related macular degeneration (AMD) is a progressive condition that affects the macula of the eye and is characterized by an increasing loss of central vision. It is the most common cause of loss of visual acuity, which can in some cases progress to blindness. This concern most commonly affects adults age 60 and older, with nearly one in ten people over age 70 affected, and as many as one in five over age 80.

The macula of the human eye contains two pigments, lutein and zeaxanthin, which are of major importance to its proper functioning. Like beta carotene, lutein and zeaxanthin are carotenoids; fat-soluble pigments produced exclusively by plants that are responsible for their intensive red, yellow or green coloring. Carotenoids are found mainly in the leaves of plants, where they participate in the process of light absorption during photosynthesis, and also protect the plant's cells against the injurious effects of light. Their protective effect can be explained in two ways. First, both substances absorb energy-rich radiation in the blue part of the spectrum (UV radiation), helping to prevent photochemical damage. Secondly, they act as antioxidants by trapping and neutralizing free radicals.

In a similar fashion, lutein and zeaxanthin help protect the eyes against UV rays in sunlight. People who spend most of the day in glaring sunlight should be aware of the danger of excessive exposure of the eyes to light, and should always make sure that their daily diet contains sufficient amounts of lutein and zeaxanthin.

Based on the scientific studies performed to date, it can be assumed that an insufficient amount of pigments (like lutein and zeaxanthin) is associated with an increased risk of developing macular concerns later in life. Furthermore, a lutein deficiency has also been shown to increase the risk of developing a clouding of the lens of the eye, as happens with cataracts. Therefore, a sufficient dietary intake of lutein and zeaxanthin via food supplements may protect the eyes significantly. The balanced composition of Visiochron® supports the physiological supply of these nutrients, helping to protect the eyes and support optimal eye function.    

Effects

Lutein and zeaxanthin: In nature, lutein and zeaxanthin are always found together. High concentrations of lutein are present in dark leafy vegetables such as cabbage, kale and spinach; however, appreciable amounts are also found in egg yolk. Zeaxanthin is also present in these food sources as well as in corn and other vegetables.

A sufficient dietary intake of lutein and zeaxanthin can help protect the eyes against age-related concerns, and promote healthier eyes in general. Once ingested, carotinoids like lutein and zeaxanthin are absorbed by the digestive system and transported by the blood to the retina, where they accumulate in the macula, exerting a protective effect on the eyes.

Visiochron® contains lutein and zeaxanthin in microcrystalline form, allowing for optimal absorption and higher bioavailability than similar products on the market. As a result of this increased bioavailability, less of these ingredients is needed to achieve the same effect.

Bilberry extract: Age-related eye concerns can often be traced back to a deterioration of the capillaries in the eye. Bilberry extract, with its naturally high anthocyanidin content, can help support healthy microcirculation, and along with the other active ingredients helps support optimal circulation to the eye.

DHA: Various fatty acids are necessary for healthy development and regeneration of tissues in the brain and eyes. Specifically, the omega 3 fatty acid DHA supports the development and preservation of healthy vision. Moreover, DHA enhances the protective effects of lutein and zeaxanthin.

Resveratrol: This standardized extract derived from red grapes is not only one of the strongest antioxidants that exists, but is also very well known for its supportive effect on the vascular system, especially thin and delicate capillaries like those found in the eyes.

Vitamin E (tocopherol) also serves to protect against oxidative damage. This fat-soluble substance is found mainly in cell membranes, where it exerts an antioxidant effect.

Vitamin C (ascorbic acid) is a water-soluble vitamin responsible for protecting tissue structures, cell membranes and cellular constituents such as proteins and enzymes against oxidative damage caused by free radicals.

Zinc: This element is an important component of many enzymes and of their co-factors. For example, zinc plays a major role in the metabolism of vitamin A, a substance of crucial importance to healthy vision. In addition, zinc is a component of many enzymes that possess antioxidant effects, thus playing an important role in protecting against free radicals.

Uses

The most important functions of lutein and zeaxanthin – and the reason for taking food supplements containing these substances – include:

• supporting normal eye function and overall eye health
• protecting against age-related concerns such as macular degeneration
• protecting against free radicals (antioxidant)
