Though preventative measures such as social distancing, wearing masks and sanitizing are important, it is equally important to build your immune system to have better chances of fighting off the coronavirus. Now before we get into what you can do to boost your immune system, it is important to note that these suggestions are based on what has been seen to work for other illnesses like influenza. There is no conclusive study, as far as we know, on the effects of different vitamins and minerals on the coronavirus in specific. However, having a balanced diet and taking an appropriate quantity of supplements is harmless and good for your health in general.
Vitamin C helps the immune system in a myriad of ways by bolstering different processes involved in fighting off foreign bodies. Vitamin C is found in many vegetables and as we all know, citrus fruits are a rich source as well. With a healthy diet you should be getting the minimum amount needed but you can add fruits to your diet or take a 500 mg or 1000 mg supplement according to your diet.
There have been studies suggesting vitamin D helps in fighting against respiratory tract infections and so it has been reasoned that it might aid in fighting against COVID 19. Vitamin D is absorbed through exposure to sunlight but as everyone is spending more time indoors during the pandemic so food rich in vitamin D such as egg yolk, cheese, and fish might be a consideration. You can also take vitamin D supplement, the daily requirement being somewhere between 0.4 to 0.85 mg.
Zinc is a mineral essential for a healthy functioning and responsive immune system and for warding off infections. Eggs, dairy products, and grains and pulses are a good source of zinc. It is also found in supplements, daily requirements being 8 mg for women and 11 mg for men. As with all supplements, care should be taken to regulate the amount taken.
