Alpha-carotene, lutein, zeaxanthin, and lycopene are also carotenoids. Beta-carotene and alpha-carotene can be turned into vitamin A, which is important for the health of the eyes and the nervous system. Antioxidants naturally complement one another, and taking one by itself in high doses can actually increase free-radical damage. Your best bet for restoring levels of carotenes is to boost your fruit and vegetable intake—which could help get rid of your gout, too!

They're a great source of lutein and zeaxanthin, two other carotenoids that, when working together, have shown enormous promise in protecting the eyes and helping to prevent macular degeneration and cataracts. Both alpha-carotene and beta-carotene convert in the body to vitamin A, which, in addition to being a great antioxidant and immune system stimulator, tur-bocharges the formation of a purple pigment in the eye called rhodopsin.

It contains calcium, magnesium, potassium, vitamin C, vitamin K, beta-carotene, and even a little of the eye-healthy carotenoids, lutein and zeaxanthin. And let's not forget the fiber.

Carotenes include beta-carotene, alpha-carotene, cryproxanthin, gamma-carotene, zeaxanthin, lutein, and lycopene. Studies have shown that beta-carotene deficiency in the cervical cells plays an etiologic role in the development of cervical dysplasia.24 In addition, a significant decrease in plasma beta-carotene levels is found in women with either cervical dysplasia or cancer of the cervix.25 It has been suspected that carotenes like lycopene, found in tomatoes, are more responsible for an improvement in dysplasia than is beta-carotene or the other carotenes.

It also helps prevent oxidative damage. zeaxanthin also prevents oxidative damage of the macula; take 3 mg with food. Taking 30 mg of zinc has been shown in some studies to be helpful for macular degeneration. Fish oils contain DHA, a substance concentrated in the retina of the eye, and the consumption of fish oils has been shown to reduce the risk of macular degeneration. Take a product that can give you 1,000 mg of DHA a day. Vitamin E complex acts as an antioxidant and has been shown to improve vision in people with age-related macular degeneration. Take 400 IU a day.

In 2001, the National Eye Institute conducted the Age-Related Eye Disease Study (AREDS), which involved more than 3,600 Natural Prescription for Preventing Macular Degeneration and Preserving Vision Multivitamin: Containing at least 500 mg vitamin C, 400 IU vitamin E, and 15 mg beta-carotene Zinc: 30-80 mg Omega-3 fatty acids: 1,000 mg (1 g) Lutein (and zeaxanthin): 10 mg for general prevention, 20-40 mg for someone who already has macular degeneration Note: All dosages are daily dosages and in pill or capsule form unless otherwise noted. people.

That diet effectively boosted the subjects' consumption of lutein about 400 percent and zeaxanthin about 300 percent. That same year it was found that the use of a lutein supplement can also increase the density of the protective macular pigment. You can, of course, get some lutein from foods such as spinach, kale, broccoli, and Brussels sprouts, though probably not enough to get the full therapeutic effect of supplements.

Phytochemicals such as carotenoids, including a-carotene, (3-carotene, lutein, lycopene, and zeaxanthin, are important fat-soluble nutrients, which are vitamin-like plant substances. These phytonutrients are involved in numerous tissue functions playing major roles as antioxidants, and in the case of lutein and zeaxanthin, they are antioxidants that serve as light-absorbing pigments in the retina and are protective of the macula. Lutein and zeaxanthin are found in egg yolks. Tomatoes are a source of lycopene and zeaxanthin.

Nutritional supplements that may be helpful Lutein (page 548) and zeaxanthin are antioxidants (page 467) in the carotenoid (page 488) family. These carotenoids, found in high concentrations in spinach, col-lard greens, and kale, have an affinity for the part of the retina where macular degeneration occurs. Once there, they protect the retina from damage caused by sunlight.10 Harvard researchers reported that people eating the most lutein and zeaxanthin—an average of 5.8 mg per day—had a 57% decreased risk of macular degeneration, compared with people eating the least.

All of the carotenoids, such as alpha and beta-carotene, lycopene, phytofluene, phytoene, canthoxanthin, lutein, and zeaxanthin, possess powerful antioxidant properties. Zinc, magnesium, and manganese can all neutralize free radicals. Zinc and manganese make up part of the antioxidant enzyme superoxide dismu-tase (SOD) which neutralizes the powerful superoxide free radical. The special fatty acid component called DHA, derived from omega-3-oils, has been shown to stimulate the production of SOD as well.

These are rich sources of certain antioxidants, called lutein8 and zeaxanthin, which protect the lens.9 Foods rich in vitamins C and E may help, too.10 You will find plenty of vitamin C in oranges, bell peppers, cantaloupe, strawberries, and kiwifruit. It also shows up in places you may not expect: cruciferous vegetables—broccoli, brussels sprouts, cauliflower, and kale—as well as tomatoes and sweet potatoes. Healthy sources of vitamin E include cooked spinach, soy milk, mangos, wheat germ, and, of course, most multivitamins.

Supplemental lutein, some of which the body converts to zeaxanthin, increases the thickness of the macular pigment and can often improve visual acuity in people with macular degeneration and retinitis pigmentosa, an inherited eye disease. How to Take Carotenoid Supplements The best source of carotenoids is a diet rich in fruits and colorful, non-starchy vegetables. If you opt for supplements, it is important to obtain a combination of beta-carotene, lycopene, and lutein. Natural beta-carotene (from algae) is superior to the synthetic form.

Though surgery may slow its progress, there is no cure for macular degeneration, which is why prevention is so important.) zeaxanthin may also help protect against different forms of cancer by scavenging free radicals and decreasing the growth of tumor cells. Food and Supplement Advice: zeaxanthin is found in substantial concentrations in watercress, Swiss chard, chicory leaves, beet greens, spinach, and okra. If your diet does not frequently include these greens, a good mixed carotenoid or antioxidant supplement with 30-130 mg. zeaxanthin taken daily with meals should be considered. 104.

Most of us have heard of beta-carotene, but there are others such as alpha carotene, lutein, lycopene, canthoxanthin, zeaxanthin, and cryptoxanthin. Diets poor in fruit and vegetable intakes deprive us of these vital antioxidants. In 1936, a Nobel Prize-winning biochemist by the name of Szent-Gyorgi isolated a factor from plants that had some rather unusual properties. He knew that seriously depriving an animal of ascorbic acid would engender bleeding gums and internal bleeding, and that the animal would finally die as a result of extreme sensitivity to stress—a condition we know as scurvy.

We know for sure that as the lutein and zeaxanthin levels increase in the macula of the eye, there is a significant decrease in the amount of harmful light rays that reach the retinal cells that produce vision. There's seems to be little doubt that the lutein/zeaxanthin provide protection. Most of us involved in AMD research feel that long before we can see clinical evidence of AMD, adverse events are occurring in the retina. Preliminary data from my studies of people at high risk for later development of AMD are highly supportive of this hypothesis.

Other members of the antioxidant carotenoid family include cryptoxanthin, alpha-carotene, zeaxanthin, lutein (page 548), and lycopene (page 548). However, unlike beta-carotene, most of these nutrients are not converted to vitamin A in significant amounts. Where is it found? Dark green and orange-yellow vegetables are good sources of beta-carotene. It is also available in supplements.
