B vitamins B: with stress and fatigue

B1 (thiamine): energy, nerves and stress resistance

Tiamin, or vitamin B1, plays a key role in the metabolism of carbohydrates, converting them into the energy necessary for the normal functioning of the body. It also participates in the functioning of the nervous system and maintaining health of the cardiovascular system. With stress and fatigue, the need for thiamine increases, since the body actively uses it to maintain the energy balance and protect nerve cells.

• Role in energy metabolism: Tiamine is a cooferment for several key enzymes involved in the Crebs cycle (tricarbon acid cycle), the main process of energy production in cells. It is necessary for decarboxylation of alpha coat acids, such as pyrowat and alpha-catglutarata, which are important intermediate products in the metabolism of carbohydrates, fats and proteins. Tiamine deficiency leads to a violation of this process and a decrease in energy production, which is manifested in fatigue and weakness.

• Nervous system support: Tiamine is important for the synthesis of acetylcholine, neurotransmitter necessary for the transfer of nerve impulses. It also protects the nerve cells from damage caused by free radicals and other toxins. With stress and fatigue, the nervous system is subjected to increased load, which increases the need for thiamine to maintain its normal functioning. Tiamine deficiency can lead to neurological symptoms such as irritability, forgetfulness, impaired coordination and peripheral neuropathy.

• Influence on stress resistance: Tiamin helps the body adapt to stress, supporting the work of the adrenal glands that secrete stress hormones, such as cortisol. It also helps to maintain a stable level of glucose in the blood, which is important to prevent sharp jumps in energy and associated mood vibrations. Chronic stress can deplete thiamine reserves in the body, which leads to a decrease in resistance to stress and deterioration of overall well -being.

• Tiamin sources: Good sources of thiamine are whole -grain products (brown rice, oatmeal, whole grain bread), pork, liver, legumes (beans, peas, lentils), nuts and seeds. Enriched products, such as bread and cereals, can also be a good source of thiamine. It is important to consider that thiamine is easily destroyed when heated, so the products should be prepared at low temperatures and avoid prolonged cooking.

• Tiamine deficit: Tiamine deficiency can occur with insufficient consumption with food, violation of absorption, increased need (for example, during pregnancy and breastfeeding) or in the presence of certain diseases (for example, alcoholism). Symptoms of thiamine deficiency include fatigue, weakness, irritability, impaired coordination, peripheral neuropathy, edema, heart failure (Beri-Beri) and Vernika-Korsakov encephalopathy (severe neurological disorder associated with alcoholism).

• Consumption recommendations: The recommended daily thiamine consumption rate is 1.2 mg for men and 1.1 mg for women. With stress and fatigue, the need for thiamine can be increased. In some cases, it can be advisable to take tiamine supplements, especially if there is a risk of deficiency. However, before taking the additives, it is necessary to consult a doctor.

• Tiamine and alcohol: Alcohol violates the absorption and metabolism of thiamine, which makes alcoholics especially vulnerable to thiamine deficiency and related neurological disorders. People who abuse alcohol are often recommended to take tiamine additives to prevent the development of Encephalopathy of Vernika-Korsakov.

• Thiamine and diabetes: People with diabetes often have a tiamine deficiency, which can aggravate neuropathy and other complications of diabetes. Tiamin additives can help improve the function of nerves and reduce the risk of diabetes complications.

• Thiamine and age: Elderly people are more susceptible to thiamine deficiency due to a decrease in appetite, violation of absorption and taking drugs that can affect thiamine metabolism. Therefore, older people are recommended to pay special attention to the consumption of products rich in thiamine, or take Tiamin additives on the recommendation of a doctor.

• Tiamin and Sport: Athletes who are especially engaged in sporting endurance need increased Tiamin consumption to maintain energy metabolism and the functioning of the nervous system. Tiamine deficiency can reduce sports indicators and increase the risk of injuries.

• Forms Tiamina: Tiamin is available in various forms, including thiamine hydrochloride (conventional form) and benfotiamine (fat -free form). Benfotiamine is better absorbed and has more bioavailability than thiamine hydrochloride, and can be more effective for the treatment of neuropathy and other states associated with thiamine deficiency.

• Tiamine safety: Tiamine is considered safe even in large doses. Side effects from taking thiamine additives are rare and usually insignificant. However, before taking Tiamin additives, you need to consult a doctor, especially if you have any diseases or take any medication.

B2 (riboflavin): cell energy, skin health and vision

Riboflavin, or vitamin B2, plays an important role in energy metabolism, functioning of cells and maintaining the health of the skin and vision. It is a coherent for several enzymes involved in the redox reactions necessary for the production of energy, growth and restoration of tissues. With stress and fatigue, riboflavin helps maintain energy balance and protect the cells from damage.

• Role in energy metabolism: Riboflavin is a component of two important coofers: the mononucleotide flavin and the Flavin Dinucleotide Flavin (FAD). These coofers are involved in many metabolic processes, including oxidation of glucose, fatty acids and amino acids. They are necessary for the transfer of electrons in the respiratory chain, which ensures the production of energy in the cells. Riboflavin deficiency leads to a violation of these processes and a decrease in energy production, which manifests itself in fatigue and weakness.

• Support for the health of the skin and mucous membranes: Riboflavin plays an important role in maintaining the health of the skin, mucous membranes and cornea of the eye. It is involved in the synthesis of collagen, protein necessary to maintain elasticity and skin elasticity. It also protects the skin from damage caused by ultraviolet radiation and other environmental factors. Riboflavin deficiency can lead to dermatitis, cracks in the corners of the mouth (angular stomatitis), inflammation of the tongue (glossitis) and photophobia.

• Vision Impact: Riboflavin is necessary to maintain the health of the cornea of the eye and prevent the development of cataracts. It participates in glucose metabolism in the cornea and protects it from damage caused by free radicals. Studies have shown that sufficient riboflavin consumption can reduce the risk of cataract, especially in older people.

• Antioxidant properties: Riboflavin acts as an antioxidant, protecting the cells from damage caused by free radicals. He participates in the regeneration of glutathione, an important antioxidant that helps neutralize free radicals and protect cells from oxidative stress. With stress and fatigue, the level of free radicals in the body increases, which increases the need for riboflavin to maintain antioxidant protection.

• Riboflavin sources: Good sources of riboflavin are dairy products (milk, yogurt, cheese), eggs, meat (especially liver and kidneys), fish, poultry, green leafy vegetables (spinach, broccoli) and enriched products (bread and cereals). Riboflavin is sensitive to light, so the products containing riboflavin should be stored in a dark place.

• Fisheries deficiency: Riboflavin deficiency can occur with insufficient consumption with food, violation of absorption, increased need (for example, during pregnancy and breastfeeding) or in the presence of certain diseases (for example, celiac disease). Symptoms of riboflavin deficiency include dermatitis, angular stomatitis, glossitis, photophobia, fatigue, weakness and anemia.

• Consumption recommendations: The recommended daily riboflavin consumption rate is 1.3 mg for men and 1.1 mg for women. With stress and fatigue, the need for riboflavin can be increased. In some cases, it can be advisable to take riboflavin additives, especially if there is a risk of deficiency. However, before taking the additives, it is necessary to consult a doctor.

• Riboflavin and Migraine: Studies have shown that high doses of riboflavin (400 mg per day) can help reduce the frequency and intensity of migraines. Riboflavin can improve the function of mitochondria in brain cells and protect them from damage caused by free radicals.

• Riboflavin and anemia: Riboflavin is necessary for the normal metabolism of iron and the synthesis of hemoglobin, a protein that suffers oxygen in the blood. Riboflavin deficiency can contribute to the development of anemia, especially in people with iron deficiency.

• Riboflavin and age: Elderly people are more susceptible to riboflavin deficiency due to a decrease in appetite, impaired absorption and medication that can affect riboflavin metabolism. Therefore, older people are recommended to pay special attention to the consumption of products rich in riboflavin, or to take riboflavin supplements on the recommendation of a doctor.

• Riboflavin and sport: Athletes, especially those engaged in sporting endurance, need increased consumption of riboflavin to maintain energy metabolism and restore tissues. Riboflavin deficiency can reduce sports indicators and increase the risk of injuries.

• Riboflavin and pregnancy: Riboflavin is important for the normal development of the fetus during pregnancy. Riboflavin deficiency can increase the risk of congenital defects. Pregnant women are advised to consume a sufficient amount of riboflavin from food or take riboflavin additives on the recommendation of a doctor.

• Riboflavin safety: Riboflavin is considered safe even in large doses. Side effects from taking riboflavin additives are rare and usually insignificant. High doses of riboflavin can paint urine in a bright yellow color, but it is harmless. However, before taking riboflavin additives, you need to consult a doctor, especially if you have any diseases or take any medication.

B3 (niacin): energy, cholesterol and nervous system

Niacin, or vitamin B3, is an important nutrient playing a key role in energy metabolism, maintaining the health of the nervous system and a decrease in blood cholesterol. It exists in two forms: nicotinic acid and nicotinamide.

• Role in energy metabolism: Niacin is a component of two important coofers: nicotinin adenin dynucleotide (NAD) and nicotinin adenin dynucleotide phosphate (NADP). These coofers are involved in many metabolic processes, including oxidation of glucose, fatty acids and amino acids. They are necessary for the transfer of electrons in the respiratory chain, which ensures the production of energy in the cells. Niacin deficiency leads to a violation of these processes and a decrease in energy production, which is manifested in fatigue and weakness.

• Nervous system support: Niacin plays an important role in maintaining the health of the nervous system and the brain. It is involved in the synthesis of neurotransmitters, such as serotonin and dopamine, which regulate mood, sleep and appetite. It also protects the nerve cells from damage caused by free radicals and other toxins. Niacin deficiency can lead to neurological symptoms such as depression, anxiety, irritability, forgetfulness and insomnia.

• Close -to -level decrease in cholesterol: Nicotinic acid, one of the forms of niacin, is used to reduce blood cholesterol. It reduces the level of “bad” cholesterol (LDL) and triglycerides and increases the level of “good” cholesterol (HDL). Nicotinic acid reduces the production of very low density (LOPP) in the liver, which are the precursors of the LDL. It also increases the activity of lipoproteinlipases, an enzyme that breaks down triglycerides into the LPU.

• Impact on the health of the skin: Niacin helps maintain skin health, protecting it from damage caused by ultraviolet radiation and other environmental factors. It also participates in the synthesis of collagen, protein necessary to maintain elasticity and skin elasticity. Niacin deficiency can lead to dermatitis, especially in areas of skin exposed to sunlight (Pellagra).

• Sources of Niacin: Good sources of niacin are meat (especially liver and kidneys), fish (tuna, salmon), poultry, peanuts, mushrooms, whole grains and enriched products (bread and cereals). The body can also synthesize niacin from the amino acid of tripophane, but this requires a sufficient amount of vitamins B1, B2 and B6.

• Niacina deficiency: Niacin deficiency can occur with insufficient consumption with food, violation of absorption or increased need (for example, during pregnancy and breastfeeding). The severe deficiency of Niacin leads to Pellagra, a disease characterized by dermatitis, diarrhea, dementia and, ultimately, death. In developed countries, Pellagra is rare, but niacin deficiency can be observed in people who abuse alcohol, having violations of nutrition or suffering from certain diseases (for example, Hartnum disease).

• Consumption recommendations: The recommended daily Niacin consumption rate is 16 mg for men and 14 mg for women. With stress and fatigue, the need for niacin can be increased. In some cases, it can be advisable to take niacin additives, especially if there is a risk of deficiency or to reduce cholesterol. However, before taking the additives, it is necessary to consult a doctor, since high doses of nicotinic acid can cause side effects, such as redness of the skin, itching, nausea and vomiting.

• Side effects of niacin: Nicotinic acid can cause redness of the skin, itching, nausea, vomiting and headache. These side effects usually take place within a few hours and can be reduced by taking nicotinic acid along with food or taking aspirin 30 minutes before niacin. Nicotinamide (niacinamide) usually does not cause redness of the skin. High doses of niacin can cause liver damage, an increase in blood glucose and heart rhythm.

• Niacin and Diabetes: Nicotinic acid can increase the level of glucose in the blood, so people with diabetes should use it with caution and under the supervision of a doctor. Nicotinamide (niacinamide) does not affect the level of glucose in the blood.

• Niacin and Medicines: Niacin can interact with some drugs such as the beds (used to reduce cholesterol), anticoagulants (lining blood) and medicines for blood pressure. Before taking Niacin additives, you need to consult a doctor, especially if you take any medicine.

• Niacin and age: Older people can be more sensitive to the side effects of Niacin. Therefore, they should use it with caution and under the supervision of a doctor.

• Niacin and pregnancy: Pregnant women should avoid taking high doses of niacin, as this can be harmful to the fetus.

• Choosing the form of niacin: Nicotinic acid and nicotinamide (niacinamide) are two forms of niacin. Nicotinic acid is more often used to reduce cholesterol, but it can cause more side effects than nicotinamide. Nicotinamide is usually used to maintain skin and nervous system health.

B5 (pantothenic acid): stress hormones, energy and skin health

Pantotenic acid, or vitamin B5, is a water -soluble vitamin necessary for the synthesis of coenzyme A (COA), which plays a key role in energy metabolism, the synthesis of hormones and cholesterol, as well as in maintaining the health of the skin. The name “pantoten” comes from the Greek word “pantothen,” which means “everywhere,” since this vitamin is present in many foods.

• Role in energy metabolism: Pantotenic acid is necessary for the formation of COA, which is involved in many metabolic reactions, including oxidation of glucose, fatty acids and amino acids. COA is necessary for the transfer of acyel groups in the Crebs cycle (tricarbon acid cycle), the main process of energy production in cells. It is also involved in the synthesis of fatty acids, cholesterol and phospholipids necessary for the construction of cell membranes. The deficiency of pantothenic acid leads to a violation of these processes and a decrease in energy production, which is manifested in fatigue and weakness.

• Support for the adrenal gland function: Pantotenic acid plays an important role in maintaining the adrenal function that produce stress hormones, such as cortisol. COA is necessary for the synthesis of cholesterol, which is the predecessor of the adrenal hormones. It is believed that sufficient consumption of pantothenic acid helps the body cope with stress and reduces the level of cortisol.

• Impact on the health of the skin: Pantotenic acid helps to maintain skin health, participating in the synthesis of collagen, a protein necessary to maintain elasticity and skin elasticity. It also helps to moisturize the skin and protects it from damage caused by ultraviolet radiation and other environmental factors. Pantotenic acid is used in some cosmetics to improve the condition of the skin and hair.

• Pantothenic acid deficiency: Pantothenic acid deficiency is rare, since this vitamin is widespread in food. However, deficiency can occur in people with severe malnutrition, violation of absorption or taking certain drugs. Symptoms of pantothenic acid deficiency include fatigue, headache, irritability, insomnia, numbness and tingling in the arms and legs, as well as abdominal pain.

• Consumption recommendations: The recommended daily pantothenic acid consumption is 5 mg for adults. With stress and fatigue, the need for pantothenic acid can be increased. In some cases, it can be advisable to take pantothenic acid supplements, especially if there is a risk of deficiency. However, before taking the additives, it is necessary to consult a doctor.

• Pantotenic acid and acne: Some studies have shown that high doses of pantothenic acid can help reduce acne (acne). It is believed that pantothenic acid reduces the production of sebum, which helps to reduce inflammation and clogging of pores.

• Pantotenic acid and wound healing: Pantotenic acid can contribute to wound healing, stimulating the formation of new skin and collagen cells.

• Pantotenic acid and medicine: Some drugs, such as antibiotics and anticonvulsants, can reduce the level of pantothenic acid in the body.

• Pantotenic acid safety: Pantotenic acid is considered safe even in large doses. Side effects from taking pantothenic acid additives are rare and usually insignificant. However, before taking the additives of pantothenic acid, you need to consult a doctor, especially if you have any diseases or you take any drugs.

• Forms of pantothenic acid: Pantotenic acid is available in various forms, including calcium pantotenate and panthenol. Panthenol, also known as provitamin B5, is often used in cosmetics to moisturize the skin and hair.

• Pantotenic acid and sport: Athletes need sufficient pantothenic acid consumption to maintain energy metabolism and restoration of tissues. Pantothenic acid deficiency can reduce sports indicators and increase the risk of injuries.

B6 (pyridoxine): Neurotransmitters, immunity and fatigue

Vitamin B6, also known as Pyridoxine, is a group of six related formations, including pyridoxine, pyridoxal and pyridoxamine. It plays an important role in more than 100 enzymatic reactions in the body, mainly associated with amino acid metabolism, as well as in the synthesis of neurotransmitters, the formation of hemoglobin and maintaining immune function.

• The role in the metabolism of amino acids: B6 is a coherent for enzymes involved in amino acid metabolism, including transamination, deamination, decarboxylation and racemization. These reactions are necessary for the synthesis of proteins, neurotransmitters and other important biologically active compounds. It also participates in gluconeogenesis (glucose synthesis from non-carb sources) and glycogenolysis (glycogen splitting), providing the body with energy.

• Synthesis neurotransmitted: B6 is necessary for the synthesis of several important neurotransmitters, such as serotonin, dopamine, norepinephrine and gamma-aminobatic acid (GABA). These neurotransmitters play a key role in the regulation of mood, sleep, appetite, cognitive function and stress reaction. B6 deficiency can lead to a decrease in the level of these neurotransmitters, which can manifest itself in depression, anxiety, irritability, insomnia and deterioration of cognitive functions.

• The formation of hemoglobin: B6 is necessary for the synthesis of hem, a component of hemoglobin, which is responsible for the transfer of oxygen in the blood. B6 deficiency can lead to microcitic anemia, characterized by small and pale red blood cells.

• Maintaining immune function: B6 plays an important role in maintaining the immune function, participating in the proliferation and differentiation of lymphocytes (immune cells). It also contributes to the production of antibodies that help fight infections. B6 deficiency can weaken the immune system and increase susceptibility to infections.

• Sources B6: Good sources B6 are meat (especially liver and poultry), fish (tuna, salmon), bananas, avocados, potatoes, spinach, nuts and whole grain products.

• Deficit B6: B6 deficiency can occur with insufficient consumption with food, violation of absorption, increased need (for example, during pregnancy and breastfeeding) or taking certain drugs (for example, isoniazida, penicillant, contraceptive tablets). Symptoms of B6 deficiency include depression, anxiety, irritability, insomnia, convulsions, peripheral neuropathy, dermatitis, glossitis, angular stomatitis and anemia.

• Consumption recommendations: The recommended daily B6 consumption rate is 1.3 mg for adults under 50 years old and 1.7 mg for men over 50 and 1.5 mg for women over 50 years old. With stress and fatigue, the need for B6 can be increased. In some cases, it can be advisable to take B6 additives, especially if there is a risk of deficiency. However, before taking the additives, it is necessary to consult a doctor, since high doses of B6 (more than 100 mg per day) can cause peripheral neuropathy.

• B6 and PMS (premenstrual syndrome): Studies have shown that B6 can help alleviate the symptoms of PMS, such as irritability, depression, anxiety, bloating and chest soreness. It is believed that B6 affects the level of neurotransmitters and hormones that regulate the mood and physical condition during the menstrual cycle.

• B6 and nausea during pregnancy: B6 is often used to treat nausea and vomiting during pregnancy. It is considered a safe and effective tool for alleviating these symptoms.

• B6 and carpal tunnel syndrome: Some studies have shown that B6 can help relieve symptoms of carpal tunnel syndrome, such as numbness and tingling in the hands and fingers.

• B6 and medicines: B6 can interact with some drugs such as levodop (used to treat Parkinson’s disease), phenytoid (anticonvulsant drug) and cycloserin (antibiotic). Before taking the B6 additives, you need to consult a doctor, especially if you take any medicine.
