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 C is a water-soluble nutrient found in many fruits and vegetables such as oranges, strawberries, bell peppers, and broccoli. It acts as an antioxidant, which means it helps neutralize unstable molecules that can damage cells. The vitamin is essential for making collagen, a protein that keeps skin, blood vessels, bones, and other tissues strong and flexible. It also helps the body absorb iron from plant-based foods and supports normal immune function. Because the body does not store vitamin C in large amounts, you need a steady supply from food or supplements each day. A severe lack of this vitamin leads to scurvy, which causes fatigue, gum problems, and weakened connective tissue. Taking very large doses from supplements can cause stomach upset and, in some people, increase the risk of kidney stones. Vitamin C matters because it helps protect tissues from oxidative stress and supports repair processes that maintain healthy organs and blood vessels. Including vitamin C–rich foods in your regular eating pattern is a simple way to support overall health and healing.
