 Can eye supplements improve vision?

It is indeed typical to believe that one or two vitamins are in charge of a specific aspect of health since different vitamins play diverse roles in the body. For instance, you would consider beta carotene or vitamin A when considering eye health.

Although both of these are crucial for eye health, there are a number of additional micronutrients (nutrients that you require in lesser amounts) that also contribute to eye protection. Learn more about these vitamins, how they promote eye health, and which foods and beverages can help you include them in your diet by reading about them.

Which vitamins are essential to keeping your eye healthy?

In general, there is a strong correlation between eating a healthy diet and preventing certain illnesses, such as diabetes, which is known to cause eye difficulties. A balanced diet may also aid in preventing the worsening of eye conditions, according to a study.

It's challenging to single out one vitamin as being essential for improving eye health. According to experts, a variety of nutrients that are regarded as advantageous on their own combine to aid in protecting your eyes. The following list of vitamins has been demonstrated to be useful in enhancing eye health:

1. Vitamin A

The retina uses particular pigments that are produced by this vitamin to enable vision. Moreover, it aids in protecting and preserving the cornea, which is the transparent front section of the eye.

2. Beta-carotene

This color belongs to the family of substances known as carotenoids, which is well recognized for providing carrots (and other fruits and vegetables) with their distinctive orange hue. The formation of vitamin A depends most heavily on beta-carotene out of all the carotenoids.

The AREDS experiment provides the clearest proof pointing out the advantages of this antioxidant. One component of the supplement, beta carotene, reduced the risk of severe age-related eye disease (AMD) by 25%. A person's central vision is impacted by AMD.

Yet, studies have indicated that high levels of beta-carotene increase the risk of lung cancer among smokers. It is important to see a healthcare professional before taking a beta carotene supplement if you already smoke. They can advise substitutes like lutein and zeaxanthin or assist you in determining whether it is safe for you. There is more information on these below.

3. zeaxanthin and lutein

The above pigments are also carotenoid pigments.

These substances were included in the formulation and beta carotene was eliminated in the AREDS2 study, a follow-up to the AREDS experiment. Also, this mixture reduced the likelihood that mild macular degeneration would progress to severe levels. They might also protect against oxidative stress and blue light damage.

Zeaxanthin & lutein's long-term effects were investigated in a 2022 study. Several substances were discovered to offer protection against late-stage AMD. They don't carry the same danger of lung cancer as beta carotene, according to the data, and may even be more helpful.

4. The vitamin C

This vitamin is crucial for lowering oxidative stress in the eyes, in addition to its other functions in the body. Your eyes are more vulnerable to injury because oxygen is broken down into free radicals there more quickly. The synthesis of collagen requires vitamin C, which is why your eyes contain a variety of collagen types. The AREDS formulation included vitamin C among its components.

 5. Vitamin E

Antioxidants that can dissolve in or combine with other fat cells make up this vitamin. Important fatty acids in the retina are shielded from free radical oxidation. Observational studies have suggested that vitamin E may help to reduce the risk of aging-related cataracts. Nevertheless, a sizable randomized controlled trial, which is the best kind of study to determine if a certain course of action leads to a given result, found no appreciable difference in cataract risk with vitamin E administration.

6. Zinc

By lowering oxidative stress, removing free radicals from the eye, and protecting the retina, this mineral supports. In the AREDS experiment, zinc also assisted in reducing the risk of developing severe AMD.

7. The omega-3 fatty acids

These nutrients are crucial for shielding the retina against oxidative damage, aging, inflammation, and even outside influences like light. Omega-3 fatty acids may aid in preventing the hardening and clogging of blood vessels in the eye, similar to its advantages for heart health.

Are supplements necessary for you to take?

Getting vitamins that are good for your eyes should ideally be done through your diet. Since the FDA does not regulate supplements, it is impossible to know for sure what ingredients they contain. Also, when you pick food over pills, you also obtain the additional nutrients the food contains, such as fiber and protein.

But National Eye Institute does point out that the supplement formulations utilized in the AREDS2 trial did contain higher doses of antioxidants and zinc than what can be obtained from a person's diet alone. However, keep in mind that the trial indicated that the supplements were only beneficial for those with intermediate or late AMD. If you think supplementing would be beneficial for you, it's best to talk to your doctor about it.

The conclusion

A number of nutrients, including vitamin A, carotenoids, and omega-3 fatty acids, are directly or indirectly related to eye health. Eating a range of nutrient-rich whole foods, particularly leafy greens, is the greatest way to receive the vitamins you need to support healthy eyes. For advice on what to eat and how to prepare it to support your health, consult a healthcare professional or dietitian.

Remember that a variety of other factors, including age and genetics, can also have an impact on your eye health. Hence, it's crucial that you continue to visit an eye doctor on a regular basis. They can make absolutely sure your eyes are in good shape.
