Nutritional supplement for eye health -
Vitamin A may also help protect against other eye afflictions. Some studies suggest that diets high in vitamin A may be associated with a reduced risk of cataracts and AMD 3 , 4 , 5 , 6.
For general eye health, vitamin-A-rich foods are recommended over supplements. Sweet potatoes are an excellent source, as are leafy green vegetables , pumpkins , and bell peppers 1.
Many eye conditions are believed to be associated with oxidative stress , which is an imbalance between antioxidants and free radicals in your body 7 , 8. Vitamin E is a potent antioxidant that helps protect your cells — including your eye cells — from damage by free radicals, which are harmful, unstable molecules 9.
In addition, some studies suggest that diets high in vitamin E may help prevent age-related cataracts. However, more research is needed as some studies show no association between vitamin E and this condition Nonetheless, a diet that includes adequate vitamin E is recommended to maintain proper eye health.
Some vitamin E-rich options include nuts, seeds, and cooking oils. Salmon , avocado , and leafy green vegetables are also good sources 9 , 12 , Like vitamin E, vitamin C is a powerful antioxidant that may protect your eyes against damaging free radicals Vitamin C and several other nutrients are used in the supplement AREDS, which may benefit those with AMD.
In addition, vitamin C is required to make collagen, a protein that provides structure to your eye, particularly in the cornea and sclera Several observational studies suggest that vitamin C may help lower your risk of developing cataracts, a condition that causes your eye to become cloudy and impairs vision Citrus and tropical fruits, bell peppers, broccoli, and kale contain particularly high amounts of vitamin C , making them great options to boost your daily intake 14 , Researchers have also studied several B vitamins for their impact on eye health, particularly vitamins B6 , B9, and B This combination of vitamins can lower levels of homocysteine , a protein in your body that may be associated with inflammation and an increased risk of developing AMD However, more research is needed to confirm the benefits of these supplements.
Another B vitamin studied in relation to eye health is riboflavin vitamin B2. As an antioxidant, riboflavin has the potential to reduce oxidative stress in your body, including your eyes Interestingly, many individuals with cataracts also are deficient in this antioxidant 23 , Health authorities recommend consuming 1.
Some examples include oats , milk , yogurt , beef , and fortified cereals The main function of niacin vitamin B3 in your body is to help convert food into energy. It can also act as an antioxidant Recently, studies have suggested that niacin may play a role in the prevention of glaucoma, a condition in which the optic nerve of your eye becomes damaged For example, an observational study on the nutrient consumption of Korean adults and their risk for glaucoma found an association between low dietary intake of niacin and this condition In addition, an animal study showed that high doses of niacin supplements were effective in preventing glaucoma Supplements should be used with caution.
When consumed in high amounts of 1. However, there is no evidence that consuming foods naturally high in niacin has any adverse effects. Some food sources include beef, poultry , fish , mushrooms , peanuts , and legumes. Lutein and zeaxanthin are part of the carotenoid family, a group of beneficial compounds synthesized by plants.
Both of these carotenoids can be found in the macula and retina of your eyes, where they help filter potentially harmful blue light , protecting your eyes from damage Several studies suggest that these plant compounds may prevent cataracts and prevent or slow the progression of AMD 33 , A randomized, controlled study found potential benefits of lutein for people with cataracts.
Over two years, those taking supplements containing 15 mg of lutein three times per week experienced improvements in vision Recommended daily intakes and safe supplemental doses have not been established for these compounds.
However, up to 20 mg of lutein per day for 2 years has been used in studies without adverse effects Nonetheless, supplements may not be necessary. As little as 6 mg of lutein and zeaxanthin may yield benefits, and a diet rich in fruits and vegetables naturally provides this amount.
Cooked spinach, kale , and collard greens are particularly high in these carotenoids Omega-3 fatty acids are a type of polyunsaturated fat. The cell membranes of your retina contain a high concentration of docosahexaenoic acid DHA , a particular type of omega-3 Besides helping form the cells of your eye, omega-3 fats have anti-inflammatory properties, which may play a role in the prevention of diabetic retinopathy.
A review of 31 studies suggested that diets high in oily fish — such as the traditional Mediterranean diet — may protect against diabetic retinopathy. Although these findings need to be corroborated with more research, they imply that fatty acids may be responsible Omega-3 fats may also benefit individuals with dry eye disease by helping them produce more tears.
With this condition, a lack of tears causes dryness , discomfort , and occasional blurry vision 37 , 39 , To increase omega-3 fatty acids in your diet, include rich sources such as fish, flaxseed , chia seeds , soy , and nuts.
Omega-3s can also be found in cooking oils such as canola and olive oil Omega-3 fatty acids have anti-inflammatory properties and may help prevent diabetic retinopathy when included in your diet.
These fats may also aid those with dry eye disease. Thiamine , or vitamin B1, plays a role in proper cell function and converting food into energy This study also indicates that protein, vitamin A, niacin, and riboflavin may protect against cataracts A clinical study found that mg of thiamine taken three times daily reduced the amount of albumin in urine — an indication of diabetic retinopathy in type 2 diabetes Food sources of thiamine include whole grains , meat, and fish.
In addition, thiamine is often added to foods like breakfast cereals, bread, and pasta Research suggests that certain vitamins and nutrients may help prevent or slow the progression of several different eye conditions.
However, eating a nutrient-dense diet rich in fruits, vegetables, whole grains, protein, and healthy fats will provide you with all the nutrients your eyes — and the rest of your body — need for optimal health. Our experts continually monitor the health and wellness space, and we update our articles when new information becomes available.
But how do you know where to start? Read on to learn about 5 vitamins and supplements that benefit your eyes. Adding omega-3 fatty acids is a natural way to support tear production and help treat dry eye.
While temporary dry eye can be irritating, chronic or severe dry eye can cause corneal scarring and impair vision. In addition, omega-3s can reduce eye inflammation and promote meibomian gland production, responsible for the oily tear layer reducing tear evaporation.
The cell membranes of your retina contain a high concentration of omega-3, supporting cell formation in the eye. In addition, omega-3 has anti-inflammatory properties , which can help prevent eye diseases, including age-related macular degeneration AMD and diabetic retinopathy DR.
Cold-water fish are a significant source of omega-3 fatty acids. Some of the best fish for omega-3 fatty acids are:. Many supplements for omega-3 use fish oil, which can sometimes give them a fishy taste.
If you consider the taste of fish or fish oil unappealing, some seeds high in omega-3 include:. Vitamin A can benefit vision in multiple ways. It helps maintain a clear cornea transparent front surface of the eye , allowing light to enter the eye correctly.
Vitamin A is also a component of rhodopsin , a protein found in photoreceptors cells rods , allowing vision in low light conditions. While omega-3 might be the most recommended nutrient for dry eye, diets rich in vitamin A can also improve tear quality.
Additionally, diets high in vitamin A also lower the risk for age-related macular degeneration AMD and cataracts. Sweet potatoes also have additional health benefits , mainly due to antioxidants.
Some vitamin A foods include:. There are also many supplements available with Vitamin A. When possible, try taking vitamin A supplements with healthy fat such as avocado , as it absorbs better.
Lutein and zeaxanthin are carotenoids produced by plants. They give fruits and vegetables a yellow or reddish hue. However, the chlorophyll in some vegetables alters the colouring, resulting in dark green.
Lutein and zeaxanthin antioxidants are recommended by the Canadian Association of Optometrists CAO to help maintain sharp vision. The carotenoids in the macula and retina also help filter blue light to prevent damage. They can also help prevent multiple eye problems, including cataracts , UV damage , and dry eye.
Lutein can also help to slow the progression of macular degeneration, which can lead to vision impairment and blindness. Foods that contain lutein and zeaxanthin include :.
Vitamin C is a powerful antioxidant. Antioxidants fight free radicals, unstable molecules that can harm cells. Diets rich in vitamin C help maintain clear vision and support the tear film by improving lubrication and production.
In addition, vitamin C is necessary to produce collagen , a structural protein that supports bone, skin, connective tissue, and tendons. In the eye, the cornea and sclera front of the eye contain high amounts of collagen. Supporting collagen in the eye can reduce the risk of developing cataracts and slow the progression of age-related macular degeneration.
Vitamin C is found in various vegetables, particularly citrus fruits. For example, kiwi is high in vitamin C. According to the Canadian Association of Optometrists , kiwi is the top eye food in the fruit category.
Some other natural sources of vitamin C include :. Vitamin C is water-soluble.
Clinical Diabetic retinopathy retinal imaging, Scientific Literature, Info for Patients: Nuttritional Supplements for Eye Conditions. Findings from the Age-Related Eye Nutritional supplement for eye health Studies AREDS and Nutditional suggest that dietary supplementation Nufritional antioxidant vitamins and healhh may slow the fof of Nutritionla macular degeneration in people who have intermediate Nurritional and those who sipplement late AMD in one eye. Supplemennt AREDS2 Nutritional supplement for eye health found that adding Chitosan for energy and zeaxanthin or omega-3 fatty acids to the original AREDS formulation with beta-carotene had no overall effect on the risk of late AMD. However, the trial also found that replacing beta-carotene with a 5-to-1 mixture of lutein and zeaxanthin may help further reduce the risk of late AMD. Data from other studies do not support using other dietary supplements, such as Ginkgo biloba and omega-3 fatty acids, for AMD. The available data on efficacy of dietary supplements for delaying the progression of or reducing the risk of developing AMD consist of several randomized controlled trials and systematic reviews. Although there are some data from observational research that dietary vitamin B12 supplements may slow or prevent cataract development, no dietary supplements have been recommended for the treatment of cataracts.Nutritional supplement for eye health -

For specific questions, please see your eye care practitioner. Several years ago, results from a study called the Age-Related Eye Disease Study AREDS provided encouraging news regarding vision and diet.
The study, funded by the National Eye Institute, included people with dry macular degeneration, at different stages of the disease. Some participants were given a daily high-dose vitamin and mineral supplement of vitamin A beta carotene , vitamin C, vitamin E, zinc and copper.
Others were given an inactive pill placebo. Over a five-year period, the participants were closely monitored, and outcomes from the two groups were compared. However, only participants in the intermediate and advanced stages of macular degeneration benefited from the supplements.
Participants with no age-related macular degeneration or in early stages of the disease saw no benefit. A few years later, the same research group conducted a second study called AREDS2 to determine if they could improve the formulation.
Based on this study, the AREDS2 formula was altered. Beta carotene was removed and lutein and zeaxanthin were added. The AREDS and AREDS2 formulations are sold at local pharmacies. You might consider taking the formulations if you have intermediate dry macular degeneration in one or both eyes or advanced dry macular degeneration in one eye but not the other and you want to keep the disease from progressing to a more advanced stage.
It may take years before you see positive results. But in addition to benefits to your eyesight, adopting these healthy habits can go a long way toward improving your overall health and quality of life.
