How Vitamin C Supports Immunity

Vitamin C, also known as ascorbic acid, is a water-soluble vitamin essential for several physiological functions, particularly immune defence. It strengthens the body’s natural barriers and helps the immune system fight pathogens effectively.

Stimulating White Blood Cells: Vitamin C increases the production and function of white blood cells, such as lymphocytes and phagocytes, which are key players in defending against infections.
Enhancing Skin Defence: Acting as an antioxidant, vitamin C helps protect the skin a primary physical barrier from environmental stressors like cold weather and pollution.
Reducing Inflammation: Infections and injuries often trigger inflammation. Vitamin C modulates inflammatory responses, helping the body recover faster.
Improving Antioxidant Defence: During colder months, oxidative stress increases due to cold exposure and winter infections. Vitamin C neutralises free radicals, thereby preserving cells from harm.
Promoting Wound Healing: Vitamin C supports collagen synthesis, which is essential for healing wounds and maintaining healthy skin.

Citrus Fruits: Oranges, lemons, limes, and grapefruit are great sources.
Berries: Strawberries, blueberries, and raspberries are packed with vitamin C and antioxidants.
Leafy Greens: Spinach, kale, and broccoli are nutrient-dense vegetables that provide vitamin C along with other essential nutrients.de
