Vitamins and nutrients are needed to keep a healthy immune system. Stress and poor diet can cause vitamin deficiency which can affect our immune function which can make us more susceptible to viral infections like the flu, norovirus or COVID.
Reminders in Taking Vitamins
Take precautions in taking vitamins even if they seem to be safe. Please take note of the following:
- Supplements are not a cure for viral infections.
- Not all supplements are safe to take without the doctor’s advice – some vitamins need a prescription.
- Consult your doctor or pharmacist first if you’re taking other medications. The vitamins may react with your prescriptions and may cause further complications to your health condition.
- Vitamin overdose can lead to a serious medical condition. Take them as prescribed and within the bounds of daily recommended intake. Carolina Pharmacy offers medication synchronization services to help patients manage their prescription medications and check if they’re taking the right dosage.
5 Vitamins to Boost your Immune System
A rainbow diet consisting of fruits and vegetables can help supply the nutrients we need every day. There are daily recommended amounts of vitamins that you’re allowed to take.
If you are not getting enough nutrients from your diet and lifestyle, supplements can help supply the following vitamins:
Vitamin D
Vitamin D is a steroid-like hormone that helps regulate the immune responses of our body to viral infections. We, humans, are like plants who need sunlight as our natural source of Vitamin D.
However, due to the lockdown, some have less time to get a good amount of sunlight to maintain the daily recommended amount of vitamin D. You may bank on Vitamin D supplements or choose food sources rich in Vitamin D to prevent deficiency.
Vitamin C
Vitamin C is known for its contribution to boosting the immune system. It is responsible for the following roles in the body:
- Creates oxygen radicals that serve as the weapon of the body against pathogens
- Involved in creating antibodies that aid in identifying if a person is infected
- Contains a lot of antioxidants
- Supports the function and ability of immune cells to fight against infection
- Contributes to cellular death by removing the old cells and replacing them with new ones
Zinc
Zinc is the gatekeeper of the immune function. It regulates the number of immune cells and helps the immune system decide when to attack and when to tolerate the pathogens entering our body.
Deficiency of this vitamin can lead to the malfunction of the internal defenses of our immune system that can make us susceptible to respiratory infections.
Protein
Protein is responsible for repairing damaged tissues and cells. It is the main component in the survival of antibodies and immune cells. Protein deficiency can paralyze our immune function and makes it harder for our body’s defense system to fight viruses.
Vitamin A
Vitamin A plays an essential role in maintaining the functional integrity of mucosal cells and immune cells in our skin and the covering of our organs. Keeping up with your Vitamin A intake helps your immune function to fight and defend the body from the transmission of viruses through the eyes, nose, and skin.
