Vitamin C is an essential micronutrient that contributes to a high-performing immune system2.
Vitamin C supports all three lines of immune defence: physical barriers (skin and mucosa), cellular defences (white blood cells), and adaptive responses (antibodies).
It helps to strengthen your physical barriers so that your body is capable of protecting itself against various foreign bodies, microbes, and viruses.
Vitamin C supports the control of general immune system, promotes production of new defensive cells and their further movement to site of infection.
This essential micronutrient also boosts adaptive responses of your immune system by influencing the production of T- and B-cells – as well as antibodies, proteins that are involved in neutralizing pathogens.
Vitamin C is crucial for your immune system to fight off any pathogens2. And a high-dose Vitamin C helps to increase your resistance against common cold and flu.
Vitamin D: Balancing your immune system
Vitamin D plays an important role in keeping your immune system balanced. If the activity of the latter is too low, frequent infections can occur. When there is too much immune system stimulation, you may be at risk of autoimmune diseases3. Balance at work!
Your immune cells release proteins to fight off infections. Vitamin D boosts this effect and protects you against cold and flu.
Zinc: Keeping your immune system strong
Zinc is best known for the role it plays in your body’s natural defences. It promotes the growth, maturation and activity of immune cells6 and is involved in nearly all immune system processes.
Zinc helps the body adjust during seasonal weather changes, as it improves the immune barrier’s integrity and prepares it to ward off colds and influenza.
Zinc plays a major role in regulating every phase of the wound healing process and helps fight against skin problems. It is a powerful antioxidant that neutralizes free radicals and participates in the growth of hair and nails.
Sufficient zinc intake can also help prevent many viral infections, including the common cold and can reduce the duration and severity of symptoms.
Remember that your immune system requires an adequate supply of vitamins and minerals to work properly. A balanced diet is a great start, but it might be a good idea to consider adding supplements to your diet if you can’t get all the nutrients you need from food alone.
