7 Potent Vision Defenses… in One Little-Known Nutrient

What’s the most beautiful, the most breath-taking sight you’ve ever seen?

Perhaps it was the North Rim of the Grand Canyon at sunrise. Seeing the ceiling of the Sistine Chapel in person. Or your first glimpse your first grandchild’s smiling face.

Imagine how you felt in that moment. The joy. The awe.

For many people the memory of that moment brings tears to their eyes. Which is appropriate, since your eyes made the memory possible.

But there’s a flip side to vision. It’s a destructive process. Every time you use your eyes, they suffer damage.

Ultraviolet (UV) light damages the delicate tissues of your eyes. Free radicals break down key vision structures. And age erodes your body’s natural defenses.

Now, the good news… You can slow, stop – or even reverse – that destructive process. Give your eyes the defensive nutrients they need to thrive, and there’s no telling how long you can enjoy a world of  bright, sharp colors.

When it comes to your eyes, the mainstream has overlooked one potent nutrient in particular. It’s so versatile, it defends your vision at least 7 ways.

In the next few moments, you’ll discover what this nutrient is, what it does, and how to use it to defend your precious sight… even into your 80s, 90s, and beyond.

Plants Can’t See, But They Can Boost Your Vision

The Cholesterol-Lowering Breakthrough the Mainstream Ignored for Over Half a CenturyYour mother or grandmother probably told you to eat your carrots because they’re good for your eyes. She might have also told you that rabbits love carrots and that’s why they can see so well.

Half of that is true. Carrots are good for your eyes… but not for rabbits. You see, carrots are too high in sugars for rabbits. They usually don’t eat root vegetables anyway.

But carrots are high in Beta-carotene, a substance your body can convert into vitamin A. And vitamin A is a key to eye health. So carrots may not be good for rabbits, but a moderate amount can help humans maintain eye health.

Like carrots, spinach can’t see, but it’s very high in lutein. Lutein is a vitamin A “cousin” that helps defend your eyes against UV damage. Lutein can help you keep your central vision sharp and clear.

We also get another key vision defender from plants. It’s called quercetin, and it’s found in lots of fruits and vegetables in small amounts. Studies suggest quercetin can help defend your vision in at least 7 ways.

Here are 7 reasons this little-known nutrient is a key ingredient in Best Life Herbals’ Visanol

#1 – Antioxidant Power for Your Eyes

Antioxidants neutralize free radicals. Free radicals damage cells by “stealing” electrons. In your eyes, free radical damage is almost constant. So antioxidant defenses is an absolute must. And quercetin really fills the bill.

VisonalIn 2007, Chinese doctors exposed human retina cells to either a damaging free radical… or the free radical plus small amounts of quercetin. The cells exposed to quercetin suffered far less damage than the cells exposed to the free radical alone.1

A more recent German study had similar results. The German scientists exposed human retina cells to various levels of quercetin – or to no quercetin. After 24, they added hydrogen peroxide – a notorious free radial generator.

They found that the human retina cells suffered less and less damage as the amount of quercetin went up.2 In other words, quercetin offers potent defenses against free radical damage.

Other scientists performed similar experiments, but looked at a different type of free radical damage.


#2– Defense Against UV Light

Ultraviolet (UV) light generates damaging free radicals. And that’s a serious threat to your vision. Because you can’t see without exposing your eyes to UV light.

University researchers in Japan exposed two groups of animals to 12 hours of light and 12 hours of darkness for 2 weeks. They gave one group quercetin. The 2nd group took a placebo.

After 2 weeks, they examined their subjects’ retinas. The quercetin group showed very little evidence of damage. But the placebo group suffered several types of free radical damage. So-called “programmed cell death” levels were also far lower in the quercetin group.3

In other words, quercetin-treated cells not only suffered less damage, they survived at higher rates.

#3 – Combating “Dry Eye”

Not every benefit is a headliner. But if you suffer with chronically dry eyes, you know how frustrating it can be. Because you use your eyes all the time.

That’s why this quercetin benefit is really bigger than it sounds.

Chronically dry eyes is a common problem in people with blood sugar problems.  So doctors in Japan looked at how quercetin affected “dry eye” in animals with similar blood sugar problems.

They discovered adding quercetin to their subjects’ diet significantly lowered their dry eye problem. In fact, quercetin seemed to reverse the damage that led to the dry eye problem.4

#4 – Supports Repair of Structural Damage

A cooperative study between scientists in Rhode Island and China revealed another quercetin benefit… Quercetin promotes healthy levels of “matrix cells.”

Your body is a lot like a building. Just like a well-built building, your body has a structural framework. This framework is made up of matrix proteins. And collagen is one of these key proteins.

Studies show exposure to UV light – and other free radicals – lowers levels of Type I collagen in key vision cells.

The international team showed that quercetin blocks this effect.5 This means quercetin can help ease the effects of these attacks on your eyes. Higher collagen levels mean faster repairs… and eyes with less damage are eyes that work better.

At this point, you can see why quercetin is so important to promoting visual health. If not, the following may do the trick… because it’s a big one.

#5 – Helps Block Clouding

Ladies - Why Your Eyes Need Extra Protection

One of the most common causes of poor vision is cloudiness. And one of the most common causes of cloudiness is the out-of-control growth of tiny blood vessels.

This growth is called “angiogenesis.” It’s the spread of (usually) unnecessary blood vessels. And it’s a major contributor to poor vision.

Back in 2008, Chinese doctors showed quercetin could help block the formation of new (unneeded) blood vessels in the retina.6

And in a 2011 study, doctors showed quercetin could encourage improved blood flow without resorting to generating new blood vessels.7

In other words, quercetin appears to boost the delivery of oxygen and nutrients to your eyes without resorting to methods that could cloud or impair your vision.

At the same time quercetin fights off this excess growth, it appears to defend against damage to healthy blood vessels.

Speaking of healthy circulation…

That’s another area where quercetin offers you an advantage. It appears to cut your risk of eye damage due to high blood sugar.8

The benefits are really adding up here. But there’s still more …

#6 – Promoting Visual Clarity

Fuzziness is the enemy of clear vision. It’s also remarkably common. Blood vessel “overgrowth” is one common cause. Lens oxidation is another.

As you age, your body’s ability to keep up with free radical slowly drops. After years of fighting, damage starts to add up faster than your body can keep up.

Your eyes’ lenses are especially sensitive to free radicals. They’re your “windows on the world,” so you can literally see the damage as it adds up. Though you may not notice at first.

Slowly but surely, the damage results in a duller, fuzzier world. If you ignore it long enough, you may lose your sight… and your independence.

Animal studies from the University of East Anglia found quercetin could help. As an antioxidant, it tends to build up in lens tissue. And it fights damage caused by some powerful free radicals.9

The result? You could enjoy clearer sight for years longer.

There’s one more enemy of clear, sharp sight to tell you about. Because quercetin may be the answer to this vision thief, as well.

#7 – Shutting Down Enzyme Damage

Earlier, we talked about quercetin fighting damage triggered by high blood sugar. A natural enzyme – aldose reductase (AR) – has been linked to several types of this damage. In particular, it builds up in lens tissue, causing clouding.

In 1975, doctors discovered quercetin blocks the activity of this enzyme. In fact, they found it was far better at locking AR activity than anything else they’d tested up to that point.10

Then, in 2006, scientists in the Middle East measured just how effective quercetin is.

They compared two groups of animals. One group had high blood sugar problems. The other had healthy blood sugar.

For 12 days, they added quercetin to two half of each groups’ diet. Then they compared AR activity in all their subjects.

The healthy subjects taking quercetin showed a 69% average drop in AR activity. In the group with blood sugar trouble, AR activity plummeted by 73%.11
