Vitamin C is an essential nutrient that helps protect your cells, supports your immune system, and plays a major role in making collagen, the protein needed for healthy skin, blood vessels, bones, and joints. It also helps your body absorb iron from plant foods and may slightly shorten the length of a cold when taken regularly.
Benefits of Vitamin C
One of vitamin C’s biggest roles is acting as an antioxidant, which helps protect cells from damage caused by free radicals. This protection supports long-term health and may help lower the risk of some chronic diseases.
Vitamin C also supports immune function by helping white blood cells work properly, and it is essential for wound healing because collagen is needed to repair skin and tissue. In addition, vitamin C improves iron absorption, which is especially helpful for people who eat little meat or rely mainly on plant-based iron sources.
Minimum daily requirements of Vitamin C
For most adult women, the recommended daily amount is 75 mg of vitamin C, and for adult men it is 90 mg per day. People who smoke need an additional 35 mg per day because smoking increases vitamin C turnover in the body.
Pregnant and breastfeeding people generally need more vitamin C than non-pregnant adults, and children need smaller amounts based on age. The upper daily limit for adults is 2,000 mg, since very high intakes can cause stomach upset or diarrhea.
Simple takeaway
Vitamin C is a small nutrient with big benefits: it supports immunity, skin health, wound healing, and iron absorption. For most adults, getting 75–90 mg a day from fruits and vegetables is enough to meet basic needs.
