Two Key Vision Defenders Doctors Rarely – if Ever – Mention
Ask your friends to name a vision nutrient, and I’ll bet most of them bring up vitamin A. They’d be right, too. Vitamin A is critical for eye health. It’s key for good low-light vision, too.
A few of your friends may have heard of lutein or zeaxanthin, too. These vitamin A “cousins” are also important for healthy vision.
But you’d be hard-pressed to find anyone who’ll mention a certain two vision powerhouses. Chances are if you asked your doctor for a list of important vision nutrients, these two wouldn’t make the list.
Even your ophthalmologist probably wouldn’t mention them. But that doesn’t make them any less important. Especially if you’re over 40. Because these two potent nutrients fight against some of the most common age-related vision problems.
Here’s what the mainstream won’t tell you about these overlooked nutrients.
The AREDS Vision Formula Is Just a Start
About 15 years ago, scientists completed a key phase of a vision study. The study was called “AREDS” – the Age-Related Eye Disease Study.
One of their most important findings was a formula that defends against one of the most common causes of vision problems in mature adults. The AREDS formula contained a mix of antioxidant vitamins, plus zinc and copper.
They’ve tinkered with it some over time, but the basic formula appears solid even today.
But AREDS is only intended to defend against one vision problem. And aging can trigger a host of attacks on your eye’s delicate tissues.
That’s why we developed Visanol. In the next few moments, you’ll discover why the AREDS formula is just a start… and how two overlooked nutrients can help you fight against vision problems AREDS wasn’t designed to address.
An Unsung Hero of Vision Defense
Vision is a complex function. It requires several complex processes to go just right in order to send an image to your brain. Maybe this complexity has kept some potent vision defenders out of the limelight.
In general, doctors seem to favor simple explanations – for fear of confusing their patients. But when it comes to your eyesight, knowing a few details could make the difference between “fuzzy” and “tack sharp.”
One of the keys to tack-sharp vision is a plant compound called “quercetin.”
Quercetin – or Q – is a flavonoid. In plants, flavonoids have many jobs. For example, they give flowers their colors. They also help defend some plants against disease.
In animals and humans, flavonoids have antioxidant powers. They can also positively impact heart health, systemic irritation, cellular mutation, and more.
As quite a few studies have shown.
Q Helps Boost Vision Health via Multiple Paths
The AREDS studies showed certain vitamins and minerals have a positive effect on vision. Other studies show Q may have similar effects.
In a 2011 animal study, Q inhibited free radical damage in retinal cells… and promoted healthy blood flow. The study’s authors marked this as another weapon in your defense against a common form of vision loss.1
Another 2011 study saw Q as a player in reducing free radical damage… and promoting clearer lenses – a key to healthy vision.2
The Scripps Research Institute also provides data on this topic. Their scientists found Q is an effective defender against free radicals. Their research suggests Q – and some other flavonoids – may offer significant defense against damaging molecules.3
In 2005, Japanese doctors offered evidence Q defends your retina – the sensitive cells on the back of your eye – against damage.
In this study, animals given Q showed less retinal damage after exposure to light.4
At this point, you may be asking, “What gives?” After all, your eyes depend on light to see. So how can that be bad?
It’s a good question. And the answer is equally important.
Vision Is a Naturally Destructive Process – Here’s Your Best Defense
When you allow light into your eyes, all forms of light enter. Including damaging ultraviolet (UV) rays. If you have sufficient defenses, you can more or less shrug off the UV attacks. If not, your vision may suffer.
That’s why quercetin is so important. Q helps defend against the damage of UV rays. So you can open your eyes… see a crisp world of vibrant colors… and maintain good eye health.
Even when German doctors exposed retinal cells directly to hydrogen peroxide, Q helped them function more normally. It bolstered their defenses.5
Scientists at Wayne State and Michigan State Universities found Q helps RPE cells defend against free radical damage. The retinal pigment epithelium (RPE) is a thin layer of cells that nourish the light-sensing cells of your retinas.
In the same study, the doctors found Q discourages production of VEGF – a compound that can trigger blood vessel growth in retinal tissue.6 These “extra” blood vessels can interfere with vision. So these scientists suggest Q may help your eyes fight against vision loss.
In a separate 2013 study, researchers in India got similar results.7 And Chinese researchers found Q specifically defends against damage caused by UV exposure.8
Quercetin Defends Vision in Other Ways, Too
One of the most common age-related vision problems is a cloudy lens. Lens clouding usually happens gradually. In fact it’s so gradual, many folks don’t realize it’s happening until the clouding is pronounced.
Many factors can lead to lens clouding. Free radical damage is a common one.
Q’s role in defending the retina – at the back of your eye – is pretty well established. But researchers in the United Kingdom showed it can help defend lens tissue as well.
Using an animal model, the scientists tested Q against a common oxidizer. When they treated lenses with Q, there was much less free radical damage. And less clouding.9
This suggests Q may help keep your lenses clearer longer. Which, in turn, can keep your world brighter and sharper.
In 2014, a Japanese research team tested Q on an animal model of dry eye.
They gave subjects with tearing problems just 1/2 of 1% of Q in their diet. This change led to more normal tearing.10
As you can probably imagine, all these potential gains make quercetin a powerful component of our Visanol… but it’s not alone. We’ve also included a closely related compound called rutin.
Building Even Stronger Defenses for Your Eyes
Imagine a world drained of color. Or one that grows progressively dimmer. It’s not a happy thought.
That’s why we put so much research into the Visanol formula. And why we included rutin – even though it’s similar to Q.
Similar, but not the same. And it offers unique vision benefits.
Animal studies show rutin is a powerful antioxidant. But it does something else. It discourages high blood sugar.
High blood sugar is another risk to your vision. It can cause your lenses to swell… or even do damage to the delicate tissue in the back of your eyes. This may result in blurriness. Or even vision loss.
In a 2006 study, animals with high blood sugar showed increased levels of insulin, lower levels of antioxidants, and higher levels of certain damaging molecules. Adding rutin to their diet led to a turn-around within 45 days.11
AGEs – advanced glycation end products – are another result of high blood sugar. These molecules can do a lot of damage – including in your eyes.
Doctors at India’s National Institute of Nutrition tested rutin against AGEs, and found it was very effective. Using lens tissue, the doctors compared rutin’s effect to untreated samples. Rutin lowered the levels of AGEs.12
In a 2008 animal study, doctors found rutin also lowers levels of aldose reductase in the lens. This enzyme can build up and lead to lens clouding.
Subjects in this study showed much lower build-up of the enzyme – and less clouding – than untreated subjects.13
Finally, a 2015 Middle Eastern study confirmed many of these same benefits. University scientists found rutin led to lower blood sugar levels, increased insulin, a boost in the antioxidant glutathione, boosted nerve growth factor… along with several other changes that increase vision defense.13
Together, Q and rutin add extra layers of defense for the delicate tissues of your eyes. Layers the basic AREDS formula – as good as it is – simply don’t offer.
Get All These Vision Defenders… and More
Why take chances with your precious vision? Especially if you have elevated blood sugar. It just makes sense to provide your eyes with the strongest defense possible.
That’s why the Visanol formula goes even further. By adding…
- Bilberry extract, rich in defensive anthocyanins. Studies show anthocyanins may support healthy low-light vision.
- Aztec Marigold, a good source of lutein. Lutein is the main component of macular pigment – your eyes’ natural UV filter.
- Betatene®, a proprietary source of mixed carotenoids. Betatene® delivers Beta-carotene, lutein, and hard-to-get zeaxanthin… all critical for healthy vision.
- Plus 13 other key nutrients for maximum vision support.
Altogether, Visanol offer 16 powerful ingredients, carefully balanced to offer your eyes the nutrition and defenses they need to stay sharp and clear.
Don’t let time drain the color or clarity out of your world. Give your vision the best defense available. Try Visanol with ZERO risk. (We’ll even show you how to save over 20%!)
Yours in continued good health,
