Vitamin C is best known for its role in supporting the immune system, but it also contributes to collagen production and helps protect cells from oxidative stress.
Fortunately, vitamin C is widely available in everyday foods.
Citrus fruits, strawberries, kiwi, peppers, tomatoes, and broccoli are all useful sources.
Eating a variety of fruits and vegetables is generally a better strategy than relying on very high-dose vitamin C supplements.
Vitamin C does not guarantee that you will avoid infections, but adequate intake supports normal immune function.
4. Vitamin E: An Antioxidant Nutrient
Vitamin E helps protect cells from oxidative damage and plays a role in normal immune function.
It can be found in foods such as almonds, sunflower seeds, vegetable oils, peanuts, and some green vegetables.
Because vitamin E is fat-soluble, the body stores it rather than quickly eliminating excess amounts. For that reason, taking large doses through supplements without medical advice isn’t necessarily beneficial and may carry risks.
