Certain vitamins and nutrients are believed to assist with meibomian gland dysfunction (MGD) and dry eye symptoms. Some of the most frequently recommended vitamins and supplements encompass omega-3 fatty acids, vitamin A, vitamin D, and vitamin E. Omega-3 fatty acids, specifically eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), possess anti-inflammatory properties and support healthy tear production. They can be obtained from sources such as fish oil, flaxseed oil, chia seeds, and walnuts. Vitamin A, which is essential for good vision, overall eye health, and the production of the mucin layer of the tear film, can be found in foods like carrots, sweet potatoes, and leafy greens or consumed as a supplement. Vitamin D, linked to overall ocular health, may aid in managing MGD by regulating inflammation and bolstering the immune system. It can be acquired through sun exposure, certain foods like fatty fish, and supplements. Lastly, vitamin E, an antioxidant vitamin, might help protect the meibomian glands from oxidative damage and can be found in foods such as nuts, seeds, and vegetable oils.
