Bad for immunity: is it worth it to take risks? Detailed analysis
Section 1: Immunity – Health Fundamental: Brief Review
-
1 What is immunity and why is it important?
Immunity is a complex system that protects the body from pathogenic agents such as bacteria, viruses, fungi and parasites. It also plays a role in the removal of damaged or mutated cells, preventing the development of cancer. The immune system consists of many components, including organs (Timus, spleen, bone marrow, lymph nodes), cells (leukocytes, lymphocytes, macrophages) and molecules (antibodies, cytokines).
Without functioning immunity, the body becomes vulnerable to infections and other diseases. A weak immunity can manifest itself with frequent colds, a long recovery, chronic fatigue, skin problems and other symptoms.
-
2 Types of immunity: congenital and acquired
Immunity is divided into two main types: congenital and acquired.
-
Inborn immunity: This is the first line of body protection. He is nonspecific and reacts quickly to any threats. The components of congenital immunity include physical barriers (skin, mucous membranes), cells (macrophages, neutrophils, NK cells) and inflammatory processes. Congenital immunity does not remember previous meetings with pathogens.
-
Acquired immunity: This type of immunity develops after the effects of the pathogen or vaccine. It is specific and remembers previous meetings with threats, which allows the body to respond faster and more efficiently with re -infection. The acquired immunity is divided into humoral (mediated by antibodies) and cellular (mediated by T-lymphocytes).
-
-
3 Factors affecting immunity
Many factors can affect the functioning of the immune system. These include:
- Age: The immune system weakens with age (immune aging).
- Nutrition: The lack of nutrients, such as vitamins, minerals and proteins, can weaken the immune system.
- Stress: Chronic stress suppresses the immune system.
- Dream: The lack of sleep negatively affects immune functions.
- Physical activity: Moderate physical activity strengthens the immunity, while excessive – can suppress.
- Diseases: Some diseases (HIV, diabetes, autoimmune disorders) weaken the immune system.
- Medicines: Some drugs (corticosteroids, immunosuppressants) can suppress immunity.
- Genetics: Genetic factors play a role in predisposition to some immune disorders.
- Environment: The influence of toxins and pollutants can weaken the immune system.
- Vaccination: Vaccination stimulates acquired immunity and protects against infectious diseases.
Section 2: Dad for immunity: What is it?

1 Definition and classification of dietary supplements
Bades (biologically active additives) are products designed to supplement the diet. They are not medicines and are not intended for the treatment of diseases. Bades may contain vitamins, minerals, amino acids, herbs, probiotics and other substances.
Classification of dietary supplements:
- Vitamin-mineral complexes: Contain vitamins and minerals necessary for the normal functioning of the body.
- Herbal additives: They contain herbs extracts that are traditionally used to maintain health.
- Probiotics and prebiotics: They contain living microorganisms (probiotics) or substances that stimulate their growth (prebiotics) to maintain intestinal health.
- Amino acids: Contain amino acids necessary for protein synthesis.
- Antioxidants: Contain substances that protect cells from damage by free radicals.
- Other additives: Include enzymes, fatty acids, fiber and other substances.
-
2 Bades positioned as “immunity amplifiers”
Many dietary supplements are positioned as means for “strengthening immunity.” Usually they contain one or more of the following components:
- Vitamin C: An antioxidant that plays a role in the functioning of immune cells.
- Vitamin D: It is necessary to activate immune cells.
- Zinc: It is important for the development and functioning of immune cells.
- Selenium: An antioxidant who plays a role in the immune system.
- SOUTINATEA: Grass that is traditionally used to treat colds.
- Black Black: It has antiviral properties.
- Propolis: It has antibacterial and anti -inflammatory properties.
- Beta-glucan: Stimulate the immune system.
- Probiotics: They support the health of the intestine that plays an important role in immunity.
-
3 Bad regulation: Differences from drugs
The regulation of dietary supplements is significantly different from the regulation of drugs. In most countries, dietary supplements do not pass strict clinical trials as medicines, and do not require approval of regulatory authorities before sale. Manufacturers of dietary supplements are not required to prove the effectiveness of their products, but only safety.
This means that the effectiveness of dietary supplements is often not confirmed by scientific research, and consumers should be careful when choosing them. It is also important to consider that dietary supplements can interact with medicines and cause side effects.
Section 3: Scientific data on the effectiveness of dietary supplements for immunity
-
1 Vitamin C: Review Review
Vitamin C is one of the most popular dietary supplements for immunity. Many studies have shown that vitamin C can reduce the duration and severity of a cold, especially in people involved in intense physical exercises. However, vitamin C does not prevent a cold in most people.
Some studies have shown that vitamin C can be useful for people with vitamin C deficiency, such as smokers and people with poor nutrition. However, for people with a normal level of vitamin C, taking high doses of vitamin C may not bring additional benefits.
High doses of vitamin C can cause side effects, such as stomach and diarrhea.
-
2 Vitamin D: Review Review
Vitamin D plays an important role in the functioning of the immune system. Vitamin D deficiency is associated with an increased risk of infections, autoimmune diseases and cancer.
Many studies have shown that vitamin D intake can reduce the risk of respiratory infections, especially in people with vitamin D deficiency. However, not all studies confirm this effect.
Vitamin D is a fat -soluble vitamin, so taking high doses can lead to toxicity.
-
3 Zinc: Review Review
Zinc is important for the development and functioning of immune cells. Zinc deficiency is associated with an increased risk of infections.
Some studies have shown that zinc intake can reduce the duration and severity of a cold, especially if you start taking it within 24 hours after the appearance of symptoms. However, zinc can cause side effects, such as nausea and a metal taste in the mouth.
Long -term intake of high doses of zinc can lead to copper deficiency.
-
4 Echinacea: Review of research
Echinacea is a grass that is traditionally used to treat a cold. Some studies have shown that Echinacea can reduce the duration and severity of a cold, but the results are ambiguous.
Echinacea can cause side effects, such as allergic reactions.
-
5 Probiotics: research review
Probiotics are living microorganisms that benefit health when consumed in sufficient quantities. Probiotics can improve intestinal health, which plays an important role in immunity.
Some studies have shown that probiotics can reduce the risk of respiratory infections and diarrhea caused by antibiotics. However, not all probiotics are the same, and effectiveness depends on the strain and dose.
Probiotics are usually safe, but can cause bloating and gases in some people.
-
6 Other dietary supplements: brief review
- Black Black: Some studies have shown that Buzina Black can reduce the duration and severity of the flu.
- Propolis: It has antibacterial and anti -inflammatory properties, but scientific data on its effectiveness for immunity are not enough.
- Beta-glucan: They stimulate the immune system, but additional studies are needed to confirm their effectiveness.
- Selenium: It is important for the immune system, but selenium deficiency is rare in developed countries.
Section 4: risks associated with the reception of dietary supplements
-
1 Lack of strict quality control
As mentioned earlier, dietary supplements do not go through strict clinical trials as medicines. This means that the quality of dietary supplements can vary, and some products may contain ingredients that are not indicated on the label, or contain pollutants.
Some dietary supplements contain ingredients that can be harmful to health, especially if you take them in high doses or for a long time.
-
2 Interaction with drugs
Bades can interact with medicines and change their effectiveness or cause side effects. It is important to inform your doctor about all the dietary supplements that you accept in order to avoid undesirable interactions.
For example, vitamin K can reduce the effectiveness of anticoagulants, and St. John’s wort can reduce the effectiveness of antidepressants and contraceptives.
-
3 Side effects
Bades can cause side effects, especially if you take them in high doses or for a long time. Side effects can vary depending on the type of dietary supplement and individual sensitivity.
Some common side effects of dietary supplements include stomach disorder, nausea, diarrhea, headache and allergic reactions.
-
4 The risk of an overdose
Reception of high doses of vitamins and minerals can lead to an overdose that can be dangerous to health. Symptoms of overdose can vary depending on the type of vitamin or mineral.
For example, an overdose of vitamin A can cause nausea, vomiting, headache and liver damage, and an overdose of iron can cause organs damage and even death.
-
5 False promises and marketing
Bad manufacturers often use false promises and aggressive marketing to attract consumers. It is important to be critical of the information that you see in the advertisement of dietary supplements, and not believe the promises of “miraculous healing.”
Remember that dietary supplements are not medicines and are not intended for the treatment of diseases.
Section 5: Badam alternatives to maintain immunity
-
1 Healthy food: the basis of immunity
Healthy nutrition is the basis for maintaining strong immunity. A balanced diet rich in fruits, vegetables, whole grains, low -fat proteins and healthy fats provides the body with the necessary nutrients for the normal functioning of the immune system.
It is important to use enough vitamins, minerals, antioxidants and fiber.
