Vitamins for heart health

Vitamins for the health of the heart: Full reference

The heart is a tireless motor of our body, providing vital blood flow and delivers oxygen and nutrients to each cell. Maintaining heart health is a priority task, and proper nutrition plays a key role in this process. Vitamins, along with minerals and other nutrients, are important components of a diet that contribute to the normal operation of the cardiovascular system. In this reference book, we will examine in detail vitamins playing a significant role in the health of the heart, their mechanisms of action, sources, recommended dosages and potential risks associated with deficiency or oversupply.

Vitamin D: sunlight for the heart

Vitamin D, often called “solar vitamin”, is synthesized in the skin under the influence of sunlight. It is also contained in some foods, such as fatty fish and enriched foods. Vitamin D plays an important role in the regulation of calcium metabolism, which, in turn, affects the health of bones and the cardiovascular system.

• The mechanism of action: Vitamin D helps to reduce inflammation, improves the function of the endothelium (inner vascular shell), reduces blood pressure and regulates cholesterol. It can also affect the function of the heart muscle and reduce the risk of heart failure. Studies show that vitamin D deficiency is associated with an increased risk of developing cardiovascular diseases, such as hypertension, coronary heart disease and stroke.

• Sources: The main source of vitamin D is sunlight. It is recommended to spend at least 15-20 minutes a day in the sun, especially during periods of low solar activity. Dietary sources include fatty fish (salmon, tuna, mackerel), egg yolks, enriched dairy products and mushrooms grown under ultraviolet light.

• Recommended dosage: The recommended daily dose of vitamin D for adults is 600 IU (international units). People with vitamin D deficiency may require a higher dose that the doctor must prescribe.

• The risks of deficiency: Vitamin D deficiency can lead to an increase in blood pressure, an increase in the risk of developing cardiovascular diseases, osteoporosis and other health problems.

• Risks of an excess: An excess of vitamin D can lead to hypercalcemia (an increased level of calcium in the blood), which can cause nausea, vomiting, weakness and other symptoms. In rare cases, hypercalcemia can lead to damage to the kidneys and cardiovascular system.

Vitamin K: calcium balance and vascular health

Vitamin K is a group of fat -soluble vitamins, playing an important role in blood coagulation and maintaining bone health. There are two main types of vitamin K: vitamin K1 (phyllokhinon) contained in green leafy vegetables, and vitamin K2 (menachinon), synthesized by bacteria in the intestines and contained in some products of animal origin and fermented products.

• The mechanism of action: Vitamin K activates the proteins necessary for blood coagulation. It also plays an important role in calcium metabolism and helps prevent the calcification of arteries. Calcification of arteries is a process in which calcium accumulates in the walls of arteries, which leads to their hardening and narrowing, increasing the risk of developing cardiovascular diseases. Vitamin K2, in particular, helps to move calcium from arteries to the bone, where it is necessary to maintain their strength.

• Sources: Vitamin K1 is contained in green leafy vegetables, such as spinach, cabbage, broccoli and salad. Vitamin K2 is contained in animal products, such as meat, eggs and cheese, as well as in fermented products, such as NATTO (fermented soybeans).

• Recommended dosage: The recommended daily dose of vitamin K for adults is 90-120 μg (microgram).

• The risks of deficiency: Vitamin K deficiency can lead to bleeding, especially in newborns. In adults, vitamin K deficiency can increase the risk of osteoporosis and calcification of arteries.

• Risks of an excess: An excess of vitamin K is rare and usually does not cause serious side effects. However, people who take anticoagulants (drugs that thin blood) should be careful when using products rich in vitamin K, as this can affect the effect of drugs.

B vitamins B: Energy for the heart and regulation of homocysteine

B vitamins are a group of water -soluble vitamins that play an important role in the metabolism of energy, the functioning of the nervous system and the health of the heart. Some vitamins of group B, such as vitamins B6, B12 and folic acid, are especially important for maintaining the health of the cardiovascular system.

• Vitamin B6 (Pyridoxin): Vitamin B6 is involved in amino acid metabolism, including homocysteine. The high level of homocysteine in the blood is associated with an increased risk of developing cardiovascular diseases. Vitamin B6 helps to turn homocysteine into other, less harmful substances.

  • Sources: Meat, fish, poultry, whole grain products, nuts, seeds, legumes and fruits (for example, bananas and avocados).

  • Recommended dosage: The recommended daily dose of vitamin B6 for adults is 1.3 mg.

• Vitamin B12 (cobalamin): Vitamin B12 is also involved in homocysteine metabolism. It is necessary for the normal functioning of the nervous system and the formation of red blood cells. Vitamin B12 deficiency can lead to anemia and neurological problems.

  • Sources: Products of animal origin, such as meat, fish, poultry, eggs and dairy products. Vegetarians and vegans are recommended to take vitamin B12 additives or use enriched products.

  • Recommended dosage: The recommended daily dose of vitamin B12 for adults is 2.4 μg.

• Folic acid (vitamin B9): Folic acid plays an important role in the formation of DNA and RNA, as well as in the metabolism of homocysteine. It is especially important for pregnant women, as it helps to prevent defects in the nervous tube in the fetus.

  • Sources: Green leafy vegetables, legumes, citrus fruits, enriched grain products.

  • Recommended dosage: The recommended daily dose of folic acid for adults is 400 mcg. Pregnant women are recommended to take 600 μg per day.

• The mechanism of action: Vitamins B6, B12 and folic acid help reduce the level of homocysteine in the blood, thereby reducing the risk of developing cardiovascular diseases. They also support the normal function of the nervous system and the formation of red blood cells, which indirectly contributes to the health of the heart.

• The risks of deficiency: The deficiency of vitamins B6, B12 and folic acid can lead to an increase in the level of homocysteine, anemia, neurological problems and other health problems.

• Risks of an excess: An excess of group B vitamins is rare, since they are water -soluble and excess is excreted from the body in the urine. However, taking high doses of vitamin B6 can lead to neurological problems.

Vitamin C: antioxidant protection for blood vessels

Vitamin C (ascorbic acid) is a powerful antioxidant that helps protect the cells from damage by free radicals. He also plays an important role in the synthesis of collagen, which is necessary to maintain the strength and elasticity of the vessels.

• The mechanism of action: Vitamin C helps prevent oxidation of LDL cholesterol (“bad” cholesterol), which is an important step in the development of atherosclerosis. It also improves the function of the endothelium, reduces blood pressure and has anti -inflammatory properties.

• Sources: Fruits and vegetables, especially citrus fruits, berries, kiwi, pepper, broccoli and spinach.

• Recommended dosage: The recommended daily dose of vitamin C for adults is 75 mg for women and 90 mg for men. Smokers are recommended to take a higher dose of vitamin C.

• The risks of deficiency: Vitamin C deficiency can lead to scurvy, disease, characterized by bleeding gums, weakness, fatigue and slow healing of wounds. Vitamin C deficiency can also increase the risk of developing cardiovascular diseases.

• Risks of an excess: An excess of vitamin C can lead to a disorder of the stomach, diarrhea and other symptoms. Reception of very high doses of vitamin C can increase the risk of kidney stones.

Vitamin E: protection against oxidative stress and atherosclerosis

Vitamin E is a group of fat -soluble antioxidants that help protect the cells from damage to free radicals. Alpha-Tocopherol is the most common and biologically active form of vitamin E.

• The mechanism of action: Vitamin E helps prevent oxidation of LDL cholesterol, reduces inflammation and improves endothelium function. He can also help prevent blood clots. Studies show that vitamin E can reduce the risk of developing cardiovascular diseases, especially in people with high risk.

• Sources: Vegetable oils (for example, wheat germ oil, sunflower oil, safflower oil), nuts, seeds, green leafy vegetables.

• Recommended dosage: The recommended daily dose of vitamin E for adults is 15 mg.

• The risks of deficiency: Vitamin E deficiency is rare, since it is widespread in food. However, vitamin E deficiency may occur in people with disorders of fat absorption.

• Risks of an excess: An excess of vitamin E can lead to bleeding, especially in people taking anticoagulants. Taking high doses of vitamin E can also increase the risk of prostate cancer.

Recommendations for taking vitamins for heart health

• Balanced nutrition: The best way to get the necessary vitamins is a balanced diet that includes a variety of fruits, vegetables, whole grain products, low -fat meat, fish and poultry.

• Consultation with a doctor: Before taking any vitamin additives, it is recommended to consult a doctor, especially if you have any diseases or you take medications.

Interaction of vitamins with drugs

It is important to know about the possible interactions of vitamins with drugs. Some vitamins can enhance or weaken the effect of drugs, as well as increase the risk of side effects.

• Vitamin K and anticoagulants: Vitamin K can reduce the effectiveness of anticoagulants (for example, warfarin). People taking anticoagulants should be careful for the use of products rich in vitamin K, and regularly monitor blood coagulation.

• Vitamin E and anticoagulants: High doses of vitamin E can increase the risk of bleeding, especially in people taking anticoagulants.

• Vitamin C and statins: Some studies show that vitamin C can reduce the effectiveness of statins (drugs that reduce cholesterol).

• Vitamin B6 and Levodopa: Vitamin B6 can reduce the effectiveness of levodopa, the drug used to treat Parkinson’s disease.

Before taking vitamin additives, especially if you take any medicine, be sure to consult a doctor to learn about possible interactions and avoid unwanted consequences.
