Virus protection: review of the best dietary supplements for immunity — a detailed guide

Understanding immunity and viral infections

What is immunity?

Immunity is a complex system of protecting the body from pathogenic agents, such as bacteria, viruses, fungi and parasites. It includes many cells, tissues and organs that work together to recognize and neutralize threats. There are two main types of immunity: congenital and acquired.

Inborn immunity — This is the first line of defense of the body. It is nonspecific and reacts quickly, but does not have immunological memory. Examples of congenital immunity include skin barriers, mucous membranes, phagocytes and inflammatory processes.

Acquired immunity — This is a more complex and specific form of immunity. It develops in response to specific antigens (substances that cause an immune response) and forms immunological memory. The acquired immunity is divided into humoral (mediated by antibodies) and cellular (mediated by T-lymphocytes).

How do viruses attack the body?

Viruses are microscopic infectious agents that cannot propagate independently. They need a living host cell for replication. Viruses penetrate the cells using various mechanisms, such as connecting with receptors on the surface of the cells and the introduction of their genetic material. After penetration, the virus intercepts control over cellular mechanisms and begins to produce new viral particles, which then infect other cells.

Viral infections can cause various diseases, from mild cold to serious and deadly diseases, such as flu, HIV/AIDS and COVID-19.

Factors affecting immunity

The state of the immune system is affected by many factors, including:

Age: Immunity is reduced with age (immune aging).
Nutrition: The lack of nutrients, such as vitamins and minerals, weakens immunity.
Stress: Chronic stress negatively affects the immune function.
Dream: The lack of sleep suppresses the immune system.
Physical activity: Moderate physical activity strengthens the immunity, and excessive ones can weaken it.
Chronic diseases: Some diseases, such as diabetes and autoimmune disorders, weaken the immunity.
Medicines: Some drugs, such as immunosuppressants, suppress the immune system.
Bad habits: Smoking and alcohol abuse weaken the immunity.

The role of dietary supplements in strengthening immunity

What are dietary supplements and how do they work?

Dietary supplements (biologically active additives) are concentrates of natural or identical to natural biologically active substances designed for direct intake or introduction into food products in order to enrich the rations with individual food or biologically active substances and their complexes. Bades are not drugs and are not intended for the treatment of diseases. They are designed to maintain health and improve the general condition of the body.

Dietary supplements for immunity contain various vitamins, minerals, plant extracts and other substances that are believed to strengthen the immune system and increase resistance to viral infections.

The main components of dietary supplements for immunity

The most common components of dietary supplements for immunity:

Vitamin C: A powerful antioxidant that stimulates the production of leukocytes and improves their function.
Vitamin D: It is important for regulating the immune system and maintaining bone health.
Zinc: It is necessary for the normal function of immune cells and has antiviral activity.
Selenium: The antioxidant that supports the function of the immune system.
SOUTINATEA: A plant that stimulates the immune system and has anti -inflammatory properties.
Black Black: It has antiviral activity and helps alleviate the symptoms of colds and influenza.
Probiotics: Useful bacteria that maintain intestinal health and strengthen the immune system.
Reishi mushrooms, Shiitaka, Maitaka: They contain beta-glucans that stimulate the immune system.

The effectiveness of dietary supplements for immunity: scientific data

The effectiveness of dietary supplements for immunity is the subject of scientific research. Some studies show that certain dietary supplements can be useful to strengthen immunity and reduce the risk of viral infections, while other studies do not reveal a significant effect. It is important to note that research results can vary depending on the dosages used, duration of administration and individual characteristics of the body.

Vitamin C: Numerous studies have shown that vitamin C can reduce the duration and severity of a cold, especially in people subject to intensive physical stress. However, its preventive action against the common cold has not been proven.

Vitamin D: Studies have shown the relationship between vitamin D deficiency and an increased risk of respiratory infections. Taking vitamin D can reduce the risk of infections, especially in people with a deficiency of this vitamin.

Zinc: Zinc plays an important role in the immune function, and its deficiency can weaken the immune system. Taking zinc can reduce the duration and severity of a cold, especially if you start taking the first 24 hours after the appearance of symptoms.

SOUTINATEA: Some studies show that echinacea can reduce the risk of colds and reduce its duration. However, the research results are contradictory.

Black Black: Studies have shown that black bezine extract can reduce the duration and severity of the flu.

Probiotics: Probiotics can strengthen immunity, improving the health of the intestine and modulating the immune response. They can reduce the risk of respiratory infections, especially in children.

Important: Before taking any dietary supplements, it is recommended to consult a doctor, especially if you have any chronic diseases or take other medicines.

Overview of the best dietary supplements for immunity

In this section, we will consider some of the most popular and effective dietary supplements to strengthen immunity available on the market. We will consider their composition, action, effectiveness, reviews and recommendations for use.

Vitamin C.

Action: Vitamin C is a powerful antioxidant that protects the cells from damage by free radicals. It stimulates the production of leukocytes (white blood cells), which play a key role in immune protection. Vitamin C is also involved in the synthesis of collagen, which is necessary to maintain the health of the skin and mucous membranes, which are a barrier against infections.

Efficiency: Studies have shown that vitamin C can reduce the duration and severity of a cold, especially in people subject to intensive physical stress. However, its preventive action against the common cold has not been proven.

Recommended dosage: The recommended daily dose of vitamin C is 75 mg for women and 90 mg for men. To strengthen immunity, you can take higher doses (up to 2000 mg per day), but you should take into account possible side effects, such as stomach disorder.
