NAC is an amino acid similar in structure to cysteine, a building block of proteins. In our body, NAC helps stimulate the production of antioxidants by replenishing the body’s levels of glutathione (see entry above).

NAC is thought to both stave off disease and play an important role in boosting the immune system.

Lutein, found in our retinas, is essential for healthy vision. Lutein and a related dietary carotenoid, zeaxanthin (see entry below), accumulate within the retina and imbue a yellow pigment that helps protect the eye.

It lowers the risk of cataracts and macular degeneration (low lutein intake is implicated as a risk factor in age-related macular degeneration), and may also help to prevent or slow down atherosclerosis.

Lutein is found in the red, orange, and yellow pigments of fruits and vegetables; for example, tomatoes, carrots, and squash. Green leafy vegetables such as spinach also contain high amounts of lutein.

Clinical research has determined that lutein along with zeaxanthin are two naturally occurring carotenoids present in the macular segment of the retina.

The concentration of these two is so high in the macula (the retinal region responsible for fine visual activities), that the carotenoids are visible as a dark yellow spot, called the macular pigment, in normal, healthy retinas. They act like sunglass filters to protect the eye.

Research performed at Harvard Medical School has established that dietary zeaxanthin plays an essential role in protecting the retina of the eye from the damaging effects of light.

Epidemiologic studies have shown that people with higher lutein/zeaxanthin levels have reduced risk for advanced stages of macular degeneration.

Blue-eyed individuals need more lutein and zeaxanthin because they have less of these protective pigments in their retinas. Again, dark, leafy greens are the dietary winner here, along with corn, nectarines, oranges, papaya and squash.

Vision Care- Vitamins For Your Sight

Vitamin B2 (riboflavin). Symptoms of lack of B2 are burning or bloodhsot eyes, conjunctivitis, eye fatigue, sensitivity to light, puli dilation, twilight blindness and dark spots in the visula field. RDA is 1.2-1.7 mg.

Vitamin B6 may be involved in regulating eye pressure and may help prevetn glaucoma. RDA is 1.6-2.0mg.

Vitamin B12 Symptoms of lack of B12 may include a general dimming of vision. RDA is 2mcg.

Vitamin C (ascorbic acid). Super vitamin. The sclera of the eyedepends on Vitamin C, and cataracts may begin when Vitamin C becomes deficient. Glaucoma may also be treated by Vitamin C, 2gm daily for six days. RDA is 60mg. There is no know toxic dose. Vitamin C should be taken with bioflavinoids.

Vitamin D and Calcium. Another important combination. There is evidence linking childhood deficiency to myopia. Vitamin D is needed for the asimilation of calcium, and the prevention of waterlogged sclera. if the fibrous tunic around the eye has excess water, the interoccular pressure may build up leading to elongation and myopia.

Vitamin D and calcium has been shown to dehydrate the water from the scelar and reduce elongation. optometrist Ben Lane showed myopic children tended to have a diet higher in refined carbohydrates and animal protein than clear seeing children. Resulting in a deficiency of minerals, vitamins, calcium and chromium, and an overabundance of phosphorus. High phosphorus reduces calcium levels. RDA for Vitamin D is 200-400IU. Vitamin D is easy to overdose on, producing elevated levels of calcium in the blood and possibly hypercalcemia. RDA for calcium is 800-1200mg.

Vitamin E Has been shown to have a positive effect on vision problems. More then 600 IU per day will however interfer with Vitamin A absorption. RDA is 9-10IU.

Zinc Dark adaption may be impaired by zinc deficiency. Taken in conjuction with Vitamin A has been shown to aleviate macular degeneration, and poor night vision. RDA is 12 -15mg. Make sure that suplemental zinc is mixed with copper and selenium.

Chromium Vital for bodily regulation of energy. Deficiencies are caused by excess sugar in diet. dose is 200 to 500mg/day.

Accommodation has been shown to depend to be sensitive to fluctuations in blood sugar levels. Sensitivities to certain foods are reflected in the state of the eyes. Leafy green vegetables are excelent for the eyes, having a detoxifying effect on the liver. Fatty foods, sugary foods, stimulants and antibiotics have a negative effect on the eyes.

What Vitamins Minerals and Herbal Supplements Do Your Eyes Need?

Here is one of them: Glutathione is an amino acid that protects the tissues surrounding the lens of the eyes. According to Web MD, “It also has potentially widespread health benefits because it can be found in all types of cells, including the cells of the immune system, whose job is to fight disease.”

Numerous studies link glutathione with the prevention of cataracts, glaucoma, retinal disease, and diabetic blindness. Foods that increase glutathione levels include sulfur-rich foods such as garlic, eggs, asparagus, and onions, and glutathione-rich foods such as watermelon, asparagus, and grapefruits.

We’re not some large vitamin manufacturer or distributor that produces every nutritional supplement known to man. And we’re not a health food store that only carries the brands and types of supplements with the biggest markup or name.

Ginkgo Biloba

The ginkgo is the oldest living tree species, growing on earth for 150-200 million years. No surprise, then, that it’s one of the most well-researched herbs in the world. Studies have confirmed that ginkgo, a powerful antioxidant:

* Increases blood flow to the retina.
* Can slow retinal deterioration which results in an
increase of visual acuity.

Retinal damage has a number of potential causes, including diabetes and macular degeneration. Studies suggest that gingko may help preserve vision in those with macular degeneration.
