Cold and flu season is just around the corner – or perhaps for your family, it’s already started. While basic hygiene measures such as handwashing and covering your mouth when you sneeze or cough are important for preventing seasonal viral infections, your amazing immune system is an invaluable line of defence if you do encounter a cold or flu virus.
How our immune system works
Our immune system is a complex network, all designed to work together to fight off pathogens – what we commonly call germs. Components of the immune system include leukocytes (white blood cells), antibodies, the complement system, the lymphatic system, bone marrow, and the spleen and thymus organs. In addition to responding to germs the moment they enter our bodies, our immune system has a process for remembering these pathogens and their characteristics, which enables our bodies to react even more swiftly the next time the same germs invade again.
The problem with the cold and flu virus is that these conditions can be caused by many different strains of the virus, so our immune systems can still be a little slow to react if they encounter a new strain.
Can IV nutrients protect from colds and flu?
The major benefit of vitamin infusions is that it delivers the nutrients you need straight into your blood circulation. This is a more efficient route than through oral supplements or food and drink, as these nutrients first need to be digested in the stomach then absorbed at some point along the gastrointestinal tract.
A number of key nutrients are known to be crucial for healthy immune function. Some of these are easy to obtain from a well-balanced diet, while others can be more challenging depending on your cultural and personal food preferences, or availability of certain foods in your community.
Some vitamins and minerals important for your immune system include:
- Vitamin C: a powerful antioxidant with multiple benefits for various components of the immune system; if taken before you catch a cold, vitamin C may help to shorten the duration of the cold and reduce the severity of your symptoms
- Vitamin D: though more commonly associated with bone health, vitamin D also helps to regulate the immune system
- Vitamin A: also known as an anti-inflammatory micronutrient, vitamin A plays an integral role in regulating the immune system
- Vitamin E: supports lymphocyte function and is one of the most important nutrients for immunoregulation
- Zinc: this micronutrient supports healthy immune function and can also specifically help to fend off viral infections
The right formulation of these important nutrients can do wonders for boosting your immune system and giving it that extra support it needs this cold and flu season.
