1. Vitamin D
Deficiency in this vitamin has become a commonplace occurrence. This is caused by consuming a poor diet, avoiding the sun, having to use sunscreen when going out, and spending most of the daylight hours indoors.
Dr. Barnish said that vitamin D is very important for the normal immune function of the body. To have sufficient vitamin D, you need to expose yourself to the sun more often. If you are unable to do that, you can instead supplement the need by increasing your intake of oily fish, eggs, and mushrooms.
2. Vitamin C
Although it has not been proven yet that increasing vitamin C consumption will ease the symptoms or curb its spread, clinical trials are currently being done to assess its power. Dr. Barnish said that vitamin C is an important player in your body’s immune system and also a very powerful antioxidant. You can increase your vitamin C intake by consuming fresh organic fruits, as well as vegetables are known to contain vitamin C. Potatoes have been identified as among the vegetables that contain vitamin C. Taking vitamin C supplements could also help. Some clinics offer patients intravenous vitamin C for the body to gain higher concentrations.
Zinc is a mineral that’s commonly added to supplements and other healthcare products like lozenges that are meant to boost your immune system. This is because zinc is essential for immune system function. Taking zinc long term is typically safe for healthy adults, as long as the daily dose is under the set upper limit of 40 mg of elemental zinc. Supplemental zinc may also help reduce the duration of the common cold. Excessive doses may interfere with copper absorption, which could increase your infection risk.
4. Elderberry Vitamin
Taking elderberry supplements may reduce upper respiratory symptoms caused by viral infections and help alleviate flu symptoms. However, more research is needed.
