Vitamins for the heart: myths and reality

Vitamins for the heart: myths and reality

Section 1: Heart and its needs: fundamental principles

The heart is not just a pump pumping blood. This is a complex organ that works tirelessly throughout life, providing every cell of the body with oxygen and nutrients. To maintain its optimal function, the heart, like any other organ, needs a certain set of nutrients. However, there is confusion between the real needs of the heart and marketing tricks that offer “miraculous” vitamins for “strengthening” the heart muscle. Before discussing specific vitamins and additives, it is important to understand the fundamental principles of a healthy heart.

• Key heart health factors: A healthy heart requires an integrated approach, including:

  • Balanced nutrition: A diet rich in fruits, vegetables, whole cereals, low-fat protein and healthy fats (omega-3) is the basis of the health of the heart. The restriction of saturated and trans fats, cholesterol and sodium is crucial.
  • Regular physical exercises: Regular physical activity strengthens the heart muscle, improves blood circulation and helps control weight and blood pressure.
  • Weight control: Excessive weight increases the load on the heart and increases the risk of cardiovascular diseases.
  • Refusal of smoking: Smoking is one of the main risk factors of heart disease.
  • Stress management: Chronic stress can negatively affect the health of the heart. It is necessary to find ways to effectively manage stress, such as meditation, yoga, or conducting time in nature.
  • Regular medical examinations: Regular examinations at the doctor allow you to identify and control risk factors for cardiovascular diseases, such as high blood pressure, high cholesterol and diabetes.

• The role of micronutrients in the heart function: Micronutrients, including vitamins and minerals, play an important role in various aspects of heart function. They participate in:

  • Energy production: The heart needs a large amount of energy for constant work. B vitamins of Coenzym Q10 (COQ10) play a key role in the production of energy in the heart cells.
  • Antioxidant protection: Free radicals formed during metabolism can damage the heart cells. Antioxidants, such as vitamins C and E, help neutralize free radicals and protect the heart from damage.
  • Maintaining vascular health: Vitamins C and D, as well as magnesium, are necessary to maintain the health and elasticity of blood vessels.
  • Blood pressure regulation: Potassium and magnesium help to regulate blood pressure and maintain a normal heart function.
  • Blood coagulation: Vitamin K plays an important role in the process of blood coagulation, preventing blood clots.

• The importance of obtaining vitamins from food: The best way to obtain the necessary vitamins and minerals is a balanced diet. A variety of diet, rich in fruits, vegetables, whole cereals, low -fat protein and healthy fats, provides the body with all the necessary nutrients. Additions should be considered only in cases where there is a deficiency of nutrients, confirmed by a medical examination. The independent purpose of vitamin additives can be not only ineffective, but also harmful.

Section 2: B vitamins B: Energy and protection for the heart

B vitamins play a key role in the metabolism of the energy necessary for the normal functioning of the heart. They also participate in the regulation of the level of homocysteine, amino acids, the increased level of which is associated with an increased risk of cardiovascular diseases.

• Vitamin B1 (TIAMIN): Thiamine is necessary for converting carbohydrates into energy. Tiamin deficiency, although it is rarely found in developed countries, can lead to cardiomyopathy (weakening of the heart muscle) and heart failure. Sources: whole cereals, legumes, meat, nuts.

• Vitamin B2 (Riboflavin): Riboflavin is involved in the production of energy and the functioning of cells. He also plays a role in antioxidant protection. Sources: milk, eggs, meat, green vegetables.

• Vitamin B3 (Niacin): Niacin helps to reduce the level of “bad” cholesterol (LDL) and increase the level of “good” cholesterol (HDL). High doses of niacin prescribed by a doctor can be used to treat a high level of cholesterol, but can have side effects. Sources: meat, fish, poultry, nuts, whole cereals.

• Vitamin B5 (pantotenic acid): Pantotenic acid is involved in the production of energy and metabolism of fat. The deficiency of pantothenic acid is extremely rare. Sources: meat, eggs, milk, vegetables.

• Vitamin B6 (Pyridoxin): Pyridoxine is involved in the metabolism of amino acids and the formation of neurotransmitters. It also helps to reduce homocysteine ​​levels. Sources: meat, fish, poultry, bananas, potatoes.

• Vitamin B7 (Biotin): Biotin is involved in the metabolism of fats, carbohydrates and proteins. Biotin’s deficiency is rare. Sources: eggs, liver, nuts, seeds.

• Vitamin B9 (folic acid): Folic acid is necessary for the growth and division of cells. It also plays an important role in reducing homocysteine ​​levels. Folic acid deficiency during pregnancy can lead to defects in the nerve tube in the fetus. Sources: green leafy vegetables, legumes, enriched cereals.

• Vitamin B12 (cobalamin): Cobalamin is necessary for the formation of red blood cells and the functioning of the nervous system. It also participates in a decrease in homocysteine ​​levels. Vitamin B12 deficiency is more common in older people and vegetarians. Sources: meat, fish, poultry, eggs, dairy products. Vegetarians and vegans are recommended to take vitamin B12 additives.

• B vitamins B and homocystein: An increased level of homocysteine ​​is a risk factor for cardiovascular diseases. Vitamins B6, B9 (folic acid) and B12 are involved in the metabolism of homocysteine, turning it into other, less harmful compounds. However, the studies have shown that taking B vitamins adds to reduce homocysteine ​​does not always lead to a decrease in the risk of cardiovascular diseases. Additional studies are needed to determine the role of group B vitamins in the prevention of heart disease.

• Myths and reality about group B vitamins and heart health:

  • Myth: Reception of large doses of B vitamins will “strengthen” the heart and prevent heart disease.
  • Reality: Balanced nutrition, rich in group B vitamins, is important for the health of the heart. However, taking large doses of group B vitamins, without confirmed deficit, will not necessarily lead to improvement of heart health and may even be harmful. You should always consult a doctor before taking vitamin additives.

Section 3: Vitamins-antioxidants: damage protection

Free radicals formed in the process of metabolism and under the influence of external factors (such as environmental pollution and smoking) can damage heart cells and contribute to the development of cardiovascular diseases. Antioxidants, such as vitamins C and E, help neutralize free radicals and protect the heart from damage.

• Vitamin C (ascorbic acid): Vitamin C is a powerful antioxidant that helps protect the cells from damage to free radicals. It also participates in the synthesis of collagen, which is necessary for the health of blood vessels. Vitamin C can help reduce blood pressure and improve the function of the endothelium (internal lining of blood vessels). Sources: citrus fruits, berries, pepper, broccoli.

• Vitamin E (Tokoferol): Vitamin E is another powerful antioxidant that helps protect cells from damage to free radicals. He can also help prevent the oxidation of “poor” cholesterol (LDL), which is an important step in the development of atherosclerosis. Sources: vegetable oils, nuts, seeds, green leafy vegetables.

• The role of antioxidants in the prevention of cardiovascular diseases: Theoretically, antioxidants should protect the heart from damage caused by free radicals. However, the results of clinical studies that studied the effects of vitamins C and E on the risk of cardiovascular diseases were contradictory. Some studies have shown that taking vitamin E additives can slightly reduce the risk of cardiovascular events in people with high risk, but other studies have not revealed any benefit. In general, there is no convincing evidence that taking vitamin C and E additives reduces the risk of cardiovascular diseases in healthy people.

• The importance of obtaining antioxidants from food: The best way to obtain antioxidants is to use a variety of fruits and vegetables. A diet, rich in fruits and vegetables, provides the body not only with vitamins C and E, but also with other useful antioxidants such as carotenoids and polyphenols. The combination of various antioxidants can be more effective than taking individual additives.

• Myths and reality about vitamins C and E and heart health:

  • Myth: Reception of large doses of vitamins C and E is guaranteed to protect the heart from damage and prevent heart disease.
  • Reality: Vitamins C and E are important antioxidants that are necessary for the health of the heart. However, there is no convincing evidence that taking large doses of these vitamins in the form of additives reduces the risk of cardiovascular diseases. The best way to obtain these vitamins is to use a variety of fruits and vegetables.

Section 4: Vitamin D: sun, bones and heart

Vitamin D is known for its role in maintaining bone health. However, studies show that vitamin D can also play an important role in the health of the cardiovascular system.

• Vitamin D and heart health: Vitamin D affects various aspects of the cardiovascular system, including:

  • Blood pressure regulation: Vitamin D helps regulate the level of renin, hormone, which affects blood pressure. Vitamin D deficiency can be associated with increased blood pressure.
  • Endothelium function: Vitamin D can improve the function of the endothelium (internal lining of blood vessels).
  • Inflammation: Vitamin D has anti -inflammatory properties and can help reduce inflammation in blood vessels.
  • The risk of cardiovascular diseases: Some studies have shown that vitamin D deficiency is associated with an increased risk of cardiovascular disease, such as coronary heart disease, stroke and heart failure. However, additional studies are needed to confirm this connection.

• Sources of vitamin D:

  • Sunlight: The main source of vitamin D is sunlight. When exposed to sunlight, the skin produces vitamin D. However, the amount of vitamin D produced by the skin depends on many factors, including the season, time of day, geographical position, skin color and the use of sunscreen.
  • Food: Vitamin D is contained in a small number of products, such as fatty fish (salmon, tuna, sardines), egg yolks and enriched products (milk, juices, cereals).
  • Supplements: Vitamin D additives can be necessary for people who do not get enough vitamin D from sunlight or food.

• Recommended dose of vitamin D: The recommended daily dose of vitamin D is 600 IU (international units) for adults up to 70 years and 800 IU for adults over 70 years old. People with vitamin D deficiency may require a higher dose prescribed by a doctor.

• Vitamin D and supplements: Before taking vitamin D additives, it is recommended to take a blood test for vitamin D level. This will help to determine if you have a deficiency of vitamin D and which dose of additives you need to take. Reception of too large doses of vitamin D can be harmful.

• Myths and reality about vitamin D and heart health:

  • Myth: Reception of vitamin D additives is guaranteed to protect the heart from diseases.
  • Reality: Vitamin D deficiency can be associated with an increased risk of cardiovascular disease. However, additional studies are needed to confirm this connection and determine whether the intake of vitamin D reduces the risk of cardiovascular diseases. It is important to maintain a sufficient level of vitamin D, receiving it from sunlight, food or additives, if necessary, under the supervision of a doctor.

Section 5: Vitamin K: blood coagulation and vascular calcification

Vitamin K is known for its role in blood coagulation. However, studies show that vitamin K can also play an important role in preventing the calcification of arteries, a process that contributes to the development of atherosclerosis.

• Vitamin K and calcification of arteries: Calcification of arteries is a process in which calcium is deposited in the walls of the arteries, making them rigid and less elastic. This contributes to the development of atherosclerosis and increases the risk of cardiovascular diseases. Vitamin K, especially vitamin K2 (menachinon), plays a role in the activation of proteins that help prevent calcium deposition in the arteries and direct it to the bones.

• Types of vitamin K: There are two main types of vitamin K:

  • Vitamin K1 (Fillohinon): Contained in green leafy vegetables.
  • Vitamin K2 (Menahinon): It is produced by bacteria in the intestines and is contained in fermented products, such as NATTO (fermented soybeans) and some cheeses.

• Sources of vitamin K:

  • Vitamin K1: Green leaf vegetables (spinach, broccoli, cabbage), vegetable oils.
  • Vitamin K2: NATTO, some cheeses, egg yolks, meat (in small quantities).

• Vitamin K and warfarin (anticoagulant): Vitamin K plays an important role in blood coagulation, so its consumption can affect the effectiveness of warfarin, anticoagulant, which is used to prevent blood clots. People taking warfarin need to maintain stable vitamin K consumption in order to avoid vibrations in blood coagulation. It is necessary to discuss the consumption of vitamin K with a doctor.

• Additional studies are needed: Additional studies are needed to determine the optimal dose of vitamin K2 for the prevention of calcification of arteries and cardiovascular diseases.

• Myths and reality about vitamin K and heart health:

  • Myth: Reception of large doses of vitamin K is guaranteed to prevent the calcification of arteries and protect the heart.
  • Reality: Vitamin K plays an important role in preventing the calcification of arteries. However, additional studies are needed to determine the optimal dose of vitamin K2 for the prevention of cardiovascular diseases. People taking warfarin need to maintain stable consumption of vitamin K and consult a doctor.

Section 6: Coenzym Q10 (CoQ10): Energy for the heart muscle

Coenzym Q10 (COQ10) is a substance that is produced in the body and is necessary for the production of energy in cells. It is also an antioxidant that helps protect the cells from damage to free radicals. The heart especially needs COQ10, as it requires a large amount of energy for constant work.

• CoQ10 and heart function: COQ10 plays a key role in the production of energy in mitochondria, energy centers. It also helps to stabilize cell membranes and protect cells from oxidative stress. COQ10 can improve the function of the heart muscle, increase physical activity tolerance and reduce fatigue.

• CoQ10 and aging: With age, the COQ10 level in the body decreases, which can lead to a decrease in energy production and an increase in oxidative stress. A decrease in the level of COQ10 can also be associated with some diseases, including heart failure, Parkinson’s disease and migraine.

• Statins and COQ10: Statins, drugs used to reduce cholesterol can reduce COQ10 in the body. Some doctors recommend taking COQ10 supplements taking statins to compensate for a decrease in the COQ10 level. However, additional studies are needed to confirm this recommendation.

• COQ10 sources: COQ10 is contained in a small number of products, such as meat, fish, poultry, nuts and vegetable oils. However, the amount of COQ10 obtained from food is usually not enough to maintain the optimal level in the body.

• CoQ10 and additives: COQ10 additives can be useful for people with low COQ10 levels, such as people with heart failure or people taking statins. However, it is necessary to consult a doctor before taking the COQ10 additives.

• Myths and reality about COQ10 and heart health:

  • Myth: Reception of COQ10 additives is a miraculous remedy for all heart diseases.
  • Reality: COQ10 plays an important role in the production of energy and antioxidant protection. COQ10 additives can be useful for people with low COQ10 levels, such as people with heart failure or people taking statins. However, additional studies are needed to determine the optimal dose of COQ10 and its role in the prevention and treatment of heart disease.

Section 7: Minerals: integral components of heart health

In addition to vitamins, minerals also play a vital role in maintaining the health of the heart and the cardiovascular system. Calcium, magnesium, potassium and sodium are only some of the minerals that are necessary for normal heart function.

• Calcium: Calcium is necessary to reduce the heart muscle and maintain normal heart rhythm. He also plays a role in blood coagulation and maintaining bone health. However, an excess of calcium, especially in the form of additives, can lead to calcification of arteries. The best source of calcium is food, such as dairy products, green leafy vegetables and enriched products.

• Magnesium: Magnesium is involved in more than 300 biochemical reactions in the body, including the regulation of blood pressure, maintaining normal heart rhythm and the functioning of the nervous system. Magnesium deficiency can be associated with an increased risk of cardiovascular diseases, arrhythmias and hypertension. Sources of magnesium: green leafy vegetables, nuts, seeds, whole cereals and legumes.

• Potassium: Potassium helps regulate blood pressure and maintain the normal function of the heart muscle. It works in tandem with sodium to maintain electrolyte balance in the body. Diet, rich in potassium and low sodium, can help reduce blood pressure. Sources of potassium: bananas, avocados, potatoes, spinach and legumes.

• Sodium: Sodium is necessary to maintain electrolyte balance and regulation of blood pressure. However, excessive consumption of sodium can lead to increased blood pressure and an increase in the risk of cardiovascular diseases. It is recommended to limit sodium consumption up to 2300 mg per day or less. The main source of sodium in the diet is processed and packaged products.

• Other minerals: Other minerals, such as zinc, selenium and copper, also play a role in maintaining heart health. However, they are usually obtained in sufficient quantities with a balanced diet.

• Myths and reality about minerals and heart health:

  • Myth: Reception of large doses of individual minerals is the best way to maintain heart health.
  • Reality: A balanced diet rich in various minerals is the best way to maintain heart health. Reception of additives of individual minerals can be necessary only in case of confirmed deficit, on the recommendation of a doctor. Excess of some minerals, such as calcium, can be harmful.

Section 8: omega-3 fatty acids: benefits for blood vessels and heart

Omega-3 fatty acids is a type of polyunsaturated fats that are necessary for human health. They have a beneficial effect on the cardiovascular system, reducing the level of triglycerides, blood pressure and the risk of blood clots.

• Types of omega-3 fatty acids: There are three main types of omega-3 fatty acids:

  • Eicosapentaenic acid (EPA): Contained in oily fish.
  • Docosahexaenic acid (DHA): Contained in oily fish.
  • Alpha-linolenic acid (Alk): Contained in vegetable oils (for example, linseed oil), nuts and seeds.

• Omega-3 and heart health: Omega-3 fatty acids have the following beneficial effects on the cardiovascular system:

  • Reducing the level of triglycerides: Triglycerides are a type of fat in the blood, the high level of which is associated with an increased risk of cardiovascular diseases.
  • Reduced blood pressure: Omega-3 fatty acids can help reduce blood pressure in people with hypertension.
  • Prevention of blood clots: Omega-3 fatty acids have an antitrombotic effect, reducing the risk of blood clots.
  • Reduction in risk of arrhythmia: Omega-3 fatty acids can help reduce the risk of arrhythmia (heart rhythm disorders).
  • Improving the function of the endothelium: Omega-3 fatty acids can improve the function of the endothelium (internal lining of blood vessels).

• Sources of omega-3 fatty acids:

  • Fat fish: Salmon, tuna, sardines, herring, mackerel.
  • Vegetable oils: Flue oil, soy oil, rapeseed oil.
  • Nuts and seeds: Walnuts, flax seeds, chia seeds.
  • Enriched products: Some eggs, yogurts and other products are enriched with omega-3 fatty acids.

• Recommended dose of omega-3 fatty acids: It is recommended to use at least two portions of fat fish per week. People who do not eat fish are recommended to take Omega-3 fatty supplements. The recommended dose of EPK and DGK is 250-500 mg per day.

• Myths and reality about omega-3 fatty acids and heart health:

  • Myth: Reception of large doses of omega-3 fatty acids is the best way to prevent heart disease.
  • Reality: Omega-3 fatty acids have a beneficial effect on the cardiovascular system. It is recommended to consume at least two portions of fat fish per week or take the supplements of omega-3 fatty acids. High doses of omega-3 fatty acids can cause side effects, such as stomach disorder and blood thinning.

Section 9: approaches to the use of vitamins for heart health

The rational use of vitamins to maintain heart health requires a conscious approach based on the scientific data and recommendations of the doctor. An uncontrolled reception of additives based on marketing promises can be not only ineffective, but also harmful.

• Personalized approach: The needs for vitamins and minerals are individual and depend on age, gender, state of health, lifestyle and diet. It is recommended to consult a doctor to assess your health state and determine the need to take vitamin additives.

• Blood test: A blood test can help identify a deficiency of vitamins and minerals. Based on the results of blood tests, the doctor can recommend taking certain vitamin additives in the required dose.

• Balanced nutrition: Balanced diet, rich in fruits, vegetables, whole cereals, low -fat protein and healthy fats, is the basis of the health of the heart. Vitamins and minerals obtained from food are better absorbed by the body and less often cause side effects.

• Additives as an addition, not replacement: Vitamin additives should be considered as an addition to a healthy lifestyle, and not as a replacement for a balanced diet and regular physical exercises.

• Caution when taking drugs: Some vitamins and minerals can interact with medicines. Be sure to inform your doctor about all the vitamin additives that you take, especially if you take medications for cardiovascular diseases, such as anticoagulants, statins or drugs to reduce blood pressure.

• The choice of quality additives: When choosing vitamin additives, pay attention to the quality of products. Choose additives from well -known manufacturers that undergo independent testing.

• Monitoring of the effect: After taking vitamin additives, it is important to regularly visit a doctor and monitor your health state. The doctor can evaluate the effectiveness of additives and adjust the dose if necessary.

• Refusal of unreasonable statements: Beware of marketing statements about “miraculous” vitamins for “strengthening” the heart. There is not a single vitamin that could instantly improve heart health. Heart health requires an integrated approach, including a healthy lifestyle and, if necessary, medical care.

Section 10: Conclusion: a reasonable approach to vitamins for a healthy heart

Vitamins and minerals play an important role in maintaining the health of the heart, but they are not a miraculous means of all heart diseases. Balanced nutrition, regular physical exercises, rejection of smoking and stress management are key components of a healthy lifestyle for the heart. Before taking vitamin additives, it is recommended to consult a doctor to determine your individual needs and avoid potential risks. A reasonable and personalized approach to the use of vitamins, based on the scientific data and recommendations of a doctor, can help support your heart health for many years.
