Food has a close link with vision and eye health. We already told you how you should eat to have healthy eyes. And then we reveal five nutraceuticals (functional foods and supplements) that will significantly protect us from vision problems. Here are 5 nutrients that improve eye health.


These small berries of dark blue color contain flavonoids. (antioxidants) That protect the eye from oxidative damage induced by light. A supplementation with blueberries decreases the progression of myopia in children. Increases the secretion of tears in people with dry eye syndrome. And suppresses the retinal damage generated by exposure to blue light. In scientific studies, blueberry products consumed for their anthocyanin content are the most commonly used. The doses range from 40 to 80 mg of cranberry anthocyanins, taken two to three times a day. It is one of the best nutrients that improve eye health.

Coenzyme Q10

Coenzyme Q10 (CoQ10) is an essential cofactor in the production of energy for cells. And a great antioxidant that protects lipids, proteins. And DNA from oxidative damage. CoQ10 protects eyes from oxidative stress generated by exposure to ultraviolet light. It is also true that it can help prevent the onset of glaucoma by normalizing intraocular pressure. Increase energy production in the cells of the retina. And protect nerve cells related to vision. A recommended dose of CoQ10 ranges from 90 to 200 mg per day. It can be found in foods of animal origin, especially in meat and organ meats. Or in bluefish (sardines, horse mackerel, tuna, herring or mackerel). Even so, there are people who take it in the form of supplementation.


The Ginkgo is a tree native to Korea, China, and Japan. Its extract, derived from the leaves, is rich in antioxidant polyphenols. These polyphenols have been shown to have neuroprotective effects on the ganglion cells of the retina and improve vascular function in the eyes; so intraocular pressure is normalized. And the risk of glaucoma is reduced. The benefits of ginkgo in relation to glaucoma are enhanced when administered with cranberry anthocyanins. Its recommended dose is 120 to 160 mg per day. It is one of the best nutrients that improve eye health.

Alpha lipoic acid

Alpha lipoic acid (ALA) is an essential cofactor for the production of cellular energy. As well as a powerful antioxidant. ALA inhibits the death of ganglion cells in the retina in cases of glaucoma and optic neuritis. It also improves visual sensitivity in type I and II diabetics. The recommended dose, according to scientific studies, is approximately 300 mg per day. It is one of the best nutrients that improve eye health.


Curcumin is a yellow pigment derived from the turmeric root. Which has numerous antioxidant properties? In animal studies, this species inhibits the degeneration of retinal cells caused by an eye injury and. When applied directly to the eye, improves the symptoms of glaucoma. It is one of the best nutrients that improve eye health.

Logically, it is not advisable to make yourself a few drops of curcumin for the eyes. There are laboratory models, including oral curcumin.
