Vitamin C
Vitamin C, also known as ascorbic acid, is the best vitamin for protecting cells and keeping them healthy, maintaining healthy skin, blood vessels, bones and cartilage, and helping with wound healing.
This vitamin is found in a wide variety of fruit and vegetables such as oranges, strawberries, broccoli, brussels sprouts, potatoes, blackcurrants and peppers.
Eating any of these plants will give you an immune system boost. Regularly eating foods full of vitamin C can help your body fight off colds and flu.
This is because vitamin C is an antioxidant and plays a role in strengthening the body’s natural defences against invaders such as viruses and bacteria.
One way it does this is by encouraging the production of white blood cells known as phagocytes and lymphocytes which help protect the body against infection.
Unlike vitamin D, our bodies don’t produce vitamin C naturally, and it is best absorbed in natural sources or supplementary form.
