IMPORTANT: The Vision Booster You’re Missing
This “Missing” Vision Booster Comes with a Bonus
If there’s one group of nutrients critical for your eyes, it’s the carotinoids. These plant pigments are related to vitamin A and play key roles in vision health.
Beta-carotene, for example, is a back-up source of vitamin A, an important antioxidant in eye tissue. Your body can only store so much vitamin A, because high levels are toxic. But Beta-carotene isn’t. Your body can safely store lots of Beta-carotene and convert it to vitamin A as needed.
Lutein and zeaxanthin are two other key carotinoids. They’re so closely linked, they’re almost always mentioned together. They’re also usually measured together… which hides an important fact. There’s a good chance you don’t get enough zeaxanthin.
You see, your eyes have tiny – but critical – filters called the macula. The macula is made up of 100% pigment – lutein and zeaxanthin (Zxn). These two substances filter out ultraviolet (UV) light, so it doesn’t hit the delicate sensory cells on the back of your eye.
Without this filter, UV rays would “fry” the sensory cells, and your vision would quickly begin to fade. And lutein and Zxn are the only carotinoids that can filter UV light this way.
That’s why you sometimes hear health experts recommend dark, leafy greens for vision health. Greens such as kale, spinach, turnip greens and Swiss chard are the best dietary sources of lutein and Zxn.
And they are, when you count the two substances together. When you separate them out, these greens are a great source of lutein… and better than nothing when it comes to Zxn.
A study published in the British Journal of Ophthalmology looked at the amounts of lutein and Zxn in a variety of carotenoid-rich foods.
The results of looking at the two pigments separately were disappointing. Dark leafy vegetables are loaded with lutein. But Zxn comprises only 0 – 3% of the carotinoids in most of these foods.1
In other words, “rich in Zxn” can still be pretty poor.
The best food sources of Zxn I’ve found are spirulina – an algae – and goji berries.
Goji berries are tasty and readily available. But they’re also expensive. Prices start at more than $1 an ounce. Spirulina is also easy to find as a nutritional supplement.
But if you’re going to take a nutritional supplement to get Zxn, it seems to me taking a complete eye formula makes more sense. And getting more Zxn may have a bonus.
Because Zxn concentrates in your eyes and your brain.
A team at Tufts University wondered if there was any relationship. And it appears there is.
The Tufts researchers gathered a group of mature adults and measured the density of the macular pigment in their eyes. They also gave them a series of tests to measure memory and mental sharpness.
They discovered the people with the best memory and sharpest minds also had the densest pigment layer in their eyes. In other words, getting plenty of Zxn may help keep more than your vision sharp.
