Introduction Glaucoma is a progressive eye disease that damages the optic nerve and leads to vision loss; it affects over 70 million people worldwide and is a leading cause of irreversible blindness (pmc.ncbi.nlm.nih.gov). A major risk factor is high intraocular pressure (IOP), but damage can occur even at normal pressure. Over time, scientists have noticed that oxidative stress (cell damage fro...
Vitamin E is a group of fat-soluble compounds found in nuts, seeds, vegetable oils, and green leafy vegetables. Its main role in the body is to act as an antioxidant that protects cell membranes from damage by free radicals. Because it dissolves in fat, vitamin E is stored in body tissues and carried in the bloodstream by fat particles. This vitamin helps preserve healthy skin, supports the immune system, and plays a role in keeping nerve cells functioning properly. Different forms of vitamin E exist, and food sources generally provide a balanced mix that the body can use. High-dose supplements can cause problems, including increasing bleeding risk in some people and interacting with certain medications. Vitamin E works together with other nutrients—for example, vitamin C can help regenerate vitamin E after it neutralizes free radicals. It matters because protecting cells from oxidative damage is one way the body defends itself against aging and some chronic conditions, so getting enough through a varied diet is important for long-term health.
