With the growing fears of corona virus and its spread on a global scale, and while the laboratories are able to find medicine and a curable vaccine, doctors and scientific research centers are advised to strengthen the immune system through 6 nutritional supplements, essential according to the "Express" scientific site and among these supplements

1- Vitamin C:

Vitamin C is considered one of the best supplements to boost the body's immune system. Vitamin C helps stimulate the production of white blood cells, which helps in combating infectious diseases and viruses. It is necessary for the repair and development of tissues. It helps to heal wounds, maintain bone health, act as an antioxidant, and fight free radicals that can weaken the immune system.

2- Zinc:

Zinc is a super-hero of immune stimulation that people often ignore when it comes to fighting a common cold. Studies have shown that zinc may help reduce the duration of colds by up to 50%.

3- Vitamin E:

Similar to vitamin C, vitamin E acts as an antioxidant that helps fight infection. It can be found in many nutritional supplements and some foods, such as almonds, peanuts, sunflower seeds and spinach.

4- Beta Glucan:

Fungus has been described as a traditional medicine in Asia for thousands of years, due to its known strength to boost immunity. In addition to having antibacterial and antiviral properties, the fungus also contains beta-glucan. This element forms the walls of the fungus cells and stimulates the immune system.

5- Vitamin D:

Vitamin D stimulates the production of anti-microbial proteins, which the body relies on to fight infection.

"The reason why this vitamin is so important is because it contains receptors that activate enzymes on the surfaces of our white blood cells," she added.

6- Iron:

Iron is an essential mineral and is necessary for the growth of cells, which are key cell components of the adaptive immune response, and low iron levels affect the body's ability to provide adequate protection from viruses, bacteria, and other pathogens.
