The Best Supplements To Support Eye Health

The Best Supplements To Support Eye Health

Eyesight is one of the most important senses for humans. Its preservation and improvement, therefore, are crucial in maintaining a high quality of life. There is a growing interest in the benefits of supplements for eye health, as multiple research studies have explored the relationship between specific vitamins, minerals, and eye-related conditions. Here is an overview of the benefits of supplements for eye health, discussing the various vitamins and minerals essential for maintaining good vision and preventing eye diseases.

The Role of Antioxidants in Eye Health

Antioxidants play a vital role in protecting the eyes from oxidative stress, an imbalance between free radicals and antioxidants in the body. Oxidative stress can lead to damage and degeneration of the eye, contributing to conditions such as age-related macular degeneration (AMD) and cataracts. Some key antioxidants for eye health include vitamins A, C, and E and other nutrients like beta carotene, zinc, lutein, zeaxanthin, and omega-3 fatty acids1.

  1. Vitamin A (and Beta Carotene)

Vitamin A is essential for vision, as it helps the retina produce certain pigments that enable us to see. A deficiency in vitamin A can lead to night blindness, particularly among older individuals, and if left untreated, it can result in permanent blindness. Beta carotene, a pigment found in many fruits and vegetables, is a precursor of vitamin A and is important for eye health. Vitamin A and beta carotene are primarily obtained from a well-balanced diet, which typically includes fortified foods like breakfast cereals2.

  1. Vitamin C

Vitamin C is a powerful antioxidant that helps protect the eyes from harmful substances and oxidative stress. It is crucial in maintaining the health of blood vessels in the eyes and may reduce the risk of developing cataracts. A diet rich in fruits and vegetables, mainly citrus fruits, can provide adequate vitamin C for maintaining good eye health.

  1. Vitamin E

Vitamin E is another essential antioxidant for eye health, as it protects cells from damage caused by free radicals. Studies have shown that vitamin E may help reduce the risk of developing AMD and cataracts. If you are not taking a Vitamin E supplement, a good source of vitamin E includes nuts, seeds, and vegetable oils3.


  1. Zinc

Zinc is an essential trace mineral that plays a critical role in maintaining the health of the retina and preventing vision loss. The Age-Related Eye Disease Studies (AREDS and AREDS2) have shown that a combination of high doses of antioxidants, including zinc, can slow AMD progression in individuals with intermediate AMD or advanced AMD in one eye.

  1. Lutein and Zeaxanthin

Lutein and zeaxanthin are carotenoids found in high concentrations in the macula, the central part of the retina responsible for sharp central vision. These nutrients act as natural antioxidants and protect the eyes from harmful blue light. The AREDS2 study found that replacing beta carotene with a 5-to-1 mixture of lutein and zeaxanthin may reduce the risk of late AMD. Lutein and zeaxanthin can be obtained from a diet rich in leafy green vegetables and highly colored fruits and vegetables4.

  1. Omega-3 Fatty Acids

Omega-3 fatty acids, particularly EPA and DHA, benefit eye health. They are essential for maintaining the structure and function of cell membranes in the retina and may help reduce the risk of AMD and dry eye syndrome. Omega-3 fatty acids can be obtained from oily fish, such as salmon, mackerel, and sardines, as well as from plant sources like flaxseeds and walnuts5.

Eye Conditions and the Benefits of Supplements

Age-Related Macular Degeneration (AMD)

AMD is a leading cause of vision loss and affects millions worldwide. The AREDS and AREDS2 studies have provided significant evidence that dietary supplementation with antioxidants and zinc can slow AMD progression in people with intermediate AMD or advanced AMD in one eye. The recommended AREDS2 supplement formulation includes vitamins C and E, lutein, zeaxanthin, zinc, and copper6.


Cataracts are a common age-related eye condition characterized by the clouding of the eye lens. While the AREDS and AREDS2 studies did not find a significant overall effect of lutein/zeaxanthin or omega-3 fatty acid supplementation on the need for cataract surgery, they did find that lutein/zeaxanthin supplementation could reduce the risk of cataract surgery by 32 percent in individuals with the lowest dietary intake of these carotenoids7.


Dry Eye Disease

Dry eye disease is common when the eyes cannot produce enough tears or moisture to maintain a healthy eye surface. Some vitamins and nutrients, such as omega-3 fatty acids, may help restore and maintain tear formation and eye lubrication. However, consultation with a healthcare professional is recommended before taking any dietary supplements for dry eye disease.

Corneal Abnormalities (Keratoconus)

Keratoconus is when the cornea becomes abnormally shaped, leading to blurred or distorted vision. Riboflavin, a B vitamin, can help absorb harmful light that may be toxic to the more internal parts of the eye. A healthcare professional can help determine if riboflavin supplementation is appropriate for individuals with corneal abnormalities8.

The benefits of supplements for eye health are well-documented, with several vitamins and minerals playing crucial roles in maintaining good vision and preventing eye diseases. While a well-balanced diet remains the best source of these essential nutrients, supplementation may be necessary for some individuals. Consult a healthcare professional to determine the most appropriate approach to maintaining good eye health through diet and supplementation.
