A Powerful – but Often Overlooked – Vision Enhancer

Dear Health-conscious Friend,

 

 A Powerful – but Overlooked – Vision Enhancer

It may well be the most potent anti-aging nutrient you’ve never heard of. Even many people who take vitamins and herbs regularly know almost nothing about quercetin.

And that’s a shame, because it boosts your body’s defenses against a host of age-related problems. Problems such as heart trouble… weak, brittle bones… breathing problems… fading brainpower… and failing sight.1,2

Cell studies even show quercetin has an anti-obesity effect. It appears to block the formation of fat cells and to trigger existing fat cells to self-destruct.3

Quercetin offers many health benefits. But today, let’s look at how it promotes healthy eyesight.

You’ll find quercetin in many foods – from apples to onions to green tea. But most foods contain only small amounts of this powerful antioxidant. That’s why I believe quercetin is a big plus in a vision formula.

Quercetin appears to promote eye health in several ways. For example, the National Eye Institute demonstrated it acts as a powerful antioxidant in eye tissue.4

English researchers, using an animal model, have shown it helps promote lens clarity.5 Since your eye’s lenses are your “windows on the world,” this is key to keeping healthy vision.

And in Japan, studies on quercetin and related antioxidants showed they have a protective effect on retinal cells, as well.6 Retinal cells line the back of your eye and act as light receptors. So they play a critical role in the color, clarity and brightness of everything you see.

All these factors make quercetin an important nutrient for your eyes. But there’s one other I should mention.

Quercetin has an effect on a specific enzyme – aldose reductase (AR). AR tends to build up in the lenses of people with high blood sugar. This build-up causes their vision to become cloudier and cloudier.

But studies have shown quercetin curbs the action of AR.

In fact, quercetin is has become something of a lab standard. Many scientists now use it as their “control” when they test new substances for activity against AR.

And here’s the kicker… About 115 million adults either have – or are at risk of – serious blood sugar problems. Which makes quercetin a powerful vision ally.

 

Finally, quercetin is 100% natural. Humans have been eating it for thousands of years, so we know it’s safe. And it has so many other health benefits.

Yours in continued good health,
