Immunity support: which dietary supplements to choose in stress and fatigue
In the modern world, full of stress and increased requirements, maintaining strong immunity becomes critical. Constant fatigue, lack of sleep, improper nutrition and emotional overload weaken the body’s defenses, making us more susceptible to infections. In such conditions, biologically active additives (dietary supplements) can become a valuable tool for strengthening immunity. However, the choice of correct dietary supplements is a difficult task, requiring an understanding of their composition, action and potential side effects. This article will examine in detail the most effective and safe dietary supplements to maintain immunity in conditions of stress and fatigue, and also provide recommendations for their use.
Understanding the relationship of stress, fatigue and immunity
Before moving on to specific dietary supplements, it is necessary to understand how stress and fatigue affect the immune system. Chronic stress caused by long -term work, financial difficulties or personal problems leads to the constant activation of the sympathetic nervous system and the release of stress hormones, such as cortisol and adrenaline.
- Impact cortisol: An increased level of cortisol has an immunosuppressive effect, suppressing the activity of immune cells, such as lymphocytes (T cells and B cells) and natural killers (NK cells). Cortisol reduces the production of cytokines, signal molecules necessary to coordinate the immune response. It can also increase inflammation in the body, which is paradoxical, but is a long -term consequence of chronic stress.
- Impact Adrenaline: Adrenaline, although useful in short -term situations (for example, with a sudden danger), in chronic stress can disrupt the function of immune cells and increase susceptibility to infections.
- Sleep violation: Fatigue, often arising due to lack of sleep and irregular regime, also weakens immunity. During sleep, the body produces and releases cytokines that are important to regulate the immune response. The lack of sleep reduces the level of these cytokines, which worsens the body’s ability to fight infections.
- Inal meals: Stress often leads to unhealthy food habits, such as eating a large amount of processed foods, sweet drinks and a lack of fresh fruits and vegetables. This deprives the body of the necessary vitamins, minerals and antioxidants necessary to maintain immune function.
As a result, weakened immunity makes a person more vulnerable to colds, flu, herpes and other infections. Chronic diseases can also exacerbate. Support for immunity in conditions of stress and fatigue requires an integrated approach, including a change in lifestyle, proper nutrition and intake of dietary supplements.
Key dietary supplements to support immunity with stress and fatigue
Consider the most effective and scientifically sound dietary supplements that can help strengthen immunity in conditions of stress and fatigue.
1. Vitamin D:
- The role in the immunity: Vitamin D plays an important role in the regulation of the immune system. It stimulates the production of antimicrobial peptides (for example, Katelicidine and Defenzines), which help to fight pathogens. Vitamin D also participates in the modulation of an inflammatory response, preventing an excessive inflammatory reaction that can damage the tissue.
- Communication with deficiency and stress: Vitamin D deficiency is widespread, especially in regions with insufficient sunlight and among people spending a lot of time in the room. Stress can aggravate the deficiency of vitamin D, since it is involved in the regulation of the level of cortisol.
- Dosage and forms: The recommended daily dose of vitamin D varies depending on the age, state of health and level of vitamin D in the blood. It is usually recommended to take 1000-2000 IU (international units) per day. In cases of a pronounced deficiency, a doctor may prescribe higher doses (for example, 5000 IU per day) for a short period of time. Vitamin D is available in two main forms: D2 (ergocalciferol) and D3 (cholegalciferol). Vitamin D3 is considered more effective, as it is better absorbed by the body.
- Cautions: Before taking vitamin D, it is recommended to take a blood test to the level of vitamin D (25-hydroxyvitamin D) and consult a doctor. Excessive consumption of vitamin D can lead to hypercalcemia (an increased level of calcium in the blood), which can cause nausea, vomiting, weakness and other symptoms.
2. Vitamin C:
- The role in the immunity: Vitamin C is a powerful antioxidant that protects the cells from damage by free radicals. It also stimulates the production and function of immune cells, such as lymphocytes and phagocytes. Vitamin C maintains the barrier function of the skin and mucous membranes, preventing the penetration of pathogens into the body.
- Communication with deficiency and stress: Stress increases the body’s need for vitamin C. The lack of vitamin C can weaken the immunity and increase the susceptibility to infections.
- Dosage and forms: The recommended daily dose of vitamin C is 75 mg for women and 90 mg for men. However, in conditions of stress and at the first signs of colds, you can increase the dose to 500-1000 mg per day. Vitamin C is available in various forms, including ascorbic acid, sodium ascorbate and liposomal vitamin C. Liposomal vitamin C is considered more bioavailable, since it is better absorbed by the body.
- Cautions: High doses of vitamin C can cause diarrhea, nausea and other gastrointestinal disorders. People with kidney diseases should be careful when taking high doses of vitamin C.
3. Zinc:
- The role in the immunity: Zinc plays an important role in the development and functioning of immune cells. It is necessary for the normal operation of Timus, the body responsible for the ripening of T-lymphocytes. Zinc is involved in the regulation of an inflammatory response and protects cells from oxidative stress.
- Communication with deficiency and stress: Zinc deficiency can weaken the immunity and increase susceptibility to infections. Stress can aggravate zinc deficiency, since it is consumed to combat inflammation and maintaining immune function.
- Dosage and forms: The recommended daily dose of zinc is 8 mg for women and 11 mg for men. At the first signs of colds, you can take up to 30 mg of zinc per day for a short period of time. Zinc is available in various forms, including zinc gluconate, zinc sulfate and zinc picoline. Zinc Picoline is considered more bioavailable.
- Cautions: High doses of zinc can cause nausea, vomiting, diarrhea and other gastrointestinal disorders. Long -term use of high doses of zinc can disrupt the absorption of copper.
4. Selenium:
- The role in the immunity: Selenium is a trace element necessary for the normal operation of the immune system. It is a component of glutathioneperoxidase, an antioxidant enzyme that protects the cells from damage by free radicals. Selenium also participates in the regulation of an inflammatory response and stimulates the activity of immune cells.
- Communication with deficiency and stress: Selena deficiency can weaken the immunity and increase susceptibility to infections. Stress can aggravate selenium deficiency, since it is consumed to combat oxidative stress.
- Dosage and forms: The recommended daily dose of selenium is 55 mcg for adults. Selenium is available in various forms, including selenometionine and sodium selenite. Seleenomeininin is considered more bioavailable.
- Cautions: High doses of selenium can cause selenosis, a condition characterized by hair loss, brittle nails, skin rashes and other symptoms.
5. Probiotics:
- The role in the immunity: Probiotics are living microorganisms, which, when used in sufficient quantities, have a beneficial effect on the health of the owner. They support a healthy intestinal microflora, which plays an important role in the immune function. The intestines are a house for most of the body’s immune cells. Probiotics stimulate the production of antibodies, improve the barrier function of the intestine and suppress the growth of pathogenic bacteria.
- Communication with dysbiosis and stress: Stress can disrupt the balance of intestinal microflora, causing dysbiosis. Dysbacteriosis can weaken the immunity and increase susceptibility to infections.
- Choosing probiotics: When choosing probiotics, you should pay attention to the strains of bacteria indicated on the package. Some strains, such as Lactobacillus Rhamnosus GG, Lactobacillus Acidophilus and Bifidobacterium Bifidum, have been well studied and proved their effectiveness in maintaining immunity. It is also important to take into account the number of colony -forming units (CFU) in each capsule. It is usually recommended to choose probiotics with a content of at least 1 billion on a dose.
- Cautions: Probiotics are usually safe for most people. However, in rare cases, they can cause bloating, gas formation and other gastrointestinal disorders, especially at the beginning of the intake.
6. Plant adaptogens:
Adaptogens are a group of plants that help the body adapt to stress and increase resistance to various adverse factors.
- Eleuterococcus (Siberian ginseng): It stimulates the immune system, increases resistance to stress and fatigue, improves mental and physical performance.
- Rodiola pink: Reduces the level of cortisol, improves mood and cognitive functions, and increases physical endurance.
- Ashwaganda: Soothes the nervous system, reduces stress and anxiety, improves sleep quality, and supports immune function.
- Ginseng: Increases energy, improves cognitive functions, stimulates the immune system.
Dosage and forms: The dosage and form of the release of plant adaptogens vary depending on the specific plant and the manufacturer. It is important to follow the instructions on the packaging and consult a doctor before starting.
Cautions: Plant adaptogens can interact with some drugs. People with autoimmune diseases, pregnant and nursing women should be careful when taking adaptogens.
7. Beta-glucan:
- The role in the immunity: Beta-glucans are polysaccharides contained in the cell walls of mushrooms, yeast and some plants. They stimulate the immune system, activating macrophages and other immune cells. Beta-glucans increase the body’s ability to fight infections and tumors.
- Sources: Beta-glucans can be obtained from various sources, such as the mushrooms of Reishi, Shiitak, Matake and Oats.
- Dosage and forms: The dosage of beta-glucans varies depending on the source and manufacturer. It is usually recommended to take 100-300 mg of beta-glucans per day.
- Cautions: Beta-glucans are usually safe for most people. However, in rare cases, they can cause allergic reactions.
8. Black Bozin Extract (Sambucus Nigra):
- The role in the immunity: Black elderberry extract contains antioxidants and antivirus compounds that help fight a cold and influenza. It reduces the duration and severity of the symptoms of respiratory infections.
- Dosage and forms: Black elderberry extract is available in various forms, including syrups, capsules and candies. The dosage varies depending on the form of release and manufacturer.
- Cautions: Black elderberry extract is usually safe for most people. However, it is not recommended to use raw berries of an elderberry, as they can be toxic.
9. N-Acetylcistein (NAC):
- The role in the immunity: NAC is the precursor of glutathione, a powerful antioxidant that protects the cells from damage by free radicals. NAC also has a mucolytic effect, diluting mucus and facilitating its discharge.
- Dosage and forms: It is usually recommended to take 600-1200 mg NAC per day.
- Cautions: NAC can interact with some drugs. People with asthma or peptic ulcer should be careful when taking NAC.
10. Curcumin:
- The role in the immunity: Kurkumin is an active ingredient in turmeric with antioxidant and anti -inflammatory properties. He modulates the immune response and helps to fight infections.
- Dosage and forms: Kurkumin is poorly absorbed by the body, so it is recommended to take it in combination with piperin (black pepper extract), which improves its bioavailability. It is usually recommended to take 500-2000 mg of curcumin per day.
- Cautions: Kurkumin can interact with some drugs. People with gallbladder diseases should be careful when taking curcumin.
