The Science Behind the VISIPRO 20-20 Formula

Vitamin A (as retinyl acetate)
Vitamin A is a vitamin that has been found to play a vital role in combating oxidative stress on the eyes*. If oxidative stress from free radicals is allowed to damage enough of the cells in the eye, the result is frequently age related macular degeneration (AMD). AMD is currently the top cause of blindness within the developed world.
Despite its common nature, much of AMD is not well understood. Therefore, it is difficult to treat. Due to the delicate nature of the retina, it is particularly susceptible to oxidative stress. However, the antioxidant properties of vitamin A can help to prevent that damage from occurring.
Still, while vitamin A can be obtained through food, it is also frequently found to be deficient in many people. Eye and vision diseases** and symptoms are among the many problems that can occur when the body does not receive a regular adequate supply of this vitamin***.

Vitamin C (as ascorbyl palmitate)
Vitamin C is a powerful antioxidant that plays a vital role in preventing and overcoming oxidative stress on the body, including the eye. This vitamin has been found to be particularly beneficial in counteracting issues regarding oxidation when it comes to various parts of the eye. It has been found to provide protection against this damage that occur as a result of “superoxide and its derivatives produced during normal cellular oxidation.”*
Other research has found that it works very effectively alongside both vitamin A and vitamin E in acting as an antioxidant in general. This combination of three powerful vitamin antioxidants are all included within this formulation.**
More research found that the regular and adequate consumption of vitamin C may lower the risk of the development of advanced or exudative age related macular degeneration (AMD).***

Vitamin E (as dl-alpha-tocopheryl succinate)
Many of us think of vitamin E as a nutrient that benefits the skin, but it also plays an extremely important role in ocular health. Research has shown that daily supplements of this nutrient can also go a long way toward supporting ocular health and preventing eye disease.
Daily supplement with vitamin E supplement does not prevent the development or progression of early or later stages of age related macular degeneration. This was found to be even more beneficial when it was combined with vitamins A and C, which are also both present in VISIPRO. The protection against AMD is exceptionally important because the degeneration is not reversible.
Many people don’t take action to protect themselves against AMD until signs of damage are already present. However, starting early to build up a daily routine of eye care and protection against AMD may make a considerable difference in delaying its onset and reducing any damage it may cause.
Vitamin E was also found to be beneficial to eye health among patients with diabetes. Patients with diabetes are at greater risk of oxidative events which can lead to retinal detachment among other ocular disorders and diseases. The study showed that when the retina is an area that experiences an especially high amount f free radical production under conditions such as diabetes, among others**. Therefore, antioxidant protection can go a long way to protect against those risks.

Zinc (as zinc oxide)
Zinc is a mineral that is key to good health and is often consumed in food. However, when taken in the proper doses, it can contribute to a strong defense against macular degeneration*. That said, it is meant to be used in combination with other substances in an overall protection against this irreversible condition. This is because in smaller doses it can be helpful but in larger doses it can be toxic.
Therefore, it must be used as a part of a broader strategy to protect eye health. This is because its benefits aren’t exclusively in macular degeneration prevention. It also plays a key role in the body’s ability to absorb vitamin A**, which is the first ingredient in VISIPRO. In fact, the presence of zinc within the body plays a role in several components of the metabolism of vitamin A, not only including its absorption but also in the way it is used.***

Selenium (as L-Selenomethionine)
Selenium is another nutrient that is becoming better understood with each passing year. What is becoming exceptionally well known is that it is associated with a wide range of benefits to ocular health.
In fact, there has been a relationship discovered between the presence of selenium and the ocular health of patients with glaucoma*. Glaucoma is a common eye disease in which the eye pressures continue to climb until this can eventually cause damage to the ocular nerve. While treatment of this disease is possible through various forms of medication and surgery, if left to harm the ocular nerve, the damage to an individual’s vision is irreversible.
In two separate rat studies, the presence of selenium** was found to have an impact on the health and integrity of the retina***. Deficient rats were found to have noticeably greater light damage on their retinas than those who had adequate levels of selenium.

Lutein
Lutein is a carotenoid that is available in food but that we rarely obtain in nearly large enough quantities to play the type of role it can play in our ocular health. Optometrists are recommending supplementation of this nutrient to an increasing degree in order to help to protect eyes and vision against a range of different types of problems. This primarily includes macular degeneration but this substance also helps in a number of other areas of eye health.
One study found that even among older adults, lutein is still effective enough to play an important role in eye health and in the prevention of age related macular disorder and other ocular disorders connected with age. Aside from AMD, lutein was also seen to provide protection against eye problems such as cataracts. The researchers behind the study stated that they believed that the lutein acted as a filter for blue light, which can have wavelengths that are damaging to parts of the eye.*
Another study was able to show that lutein is adequately effective that it could even help in the eyes of patients who had received human donor eyes in transplants.** This reveals a meaningful impact on the health and function of the eye.

Zeaxanthin
Zeaxanthin is a nutrient frequently supplemented along with lutein due to their combined benefits for eye health.
One study found that as lutein and zeaxanthin make up the pigment of the eye (the only two carotenoids that are found within the human eye lens) there is an inverse relationship between the presence of those substances and many age related eye issues. Moreover, macular pigment density and lens density had an inverse and age-dependent relationship. Therefore, the study concluded* that obtaining lutein and zeaxanthin through supplementation or diet can, together, slow age-related increases in the density of the lens.
Another study found that the majority of the carotenoids – including lutein and zeaxanthin – that are in the human peripheral retina can also be found within the rod outer segments. Those ROS carotenoids have been linked with soluble or salt-dependently bound proteins**.
Yet another study only underscored the fact that lutein and zeaxanthin are a powerful combination specifically for eye health and the prevention of ocular diseases***. That said, they may also, to a lesser extent, help the body in protecting itself against cardiovascular disease and certain cancers.
