Vitamin

Vitamin is an organic substance that the body needs in very small quantities for normal growth and development; These substances cannot be synthesized in the body, so they enter it mainly with food. Vitamins are divided into two groups depending on whether they are soluble in water or fat: water-soluble (vitamin B complex and vitamin C); fat soluble (A, D, E and K). Insufficient intake of any vitamin from food can lead to the development of characteristic diseases in a person.

VITAMIN A (vitamin A), RETINOL (retinal) - fat-soluble vitamin. It is found in large quantities in animal products (especially dairy products, egg yolks and liver) and in some plant products (for example, carrots, cabbage and lettuce); in the body it is formed from the pigment carotene. This vitamin is essential for normal bone growth, vision in dim light, and maintenance of the structure and function of mucous membranes. (Vitamin A is an active antioxidant) Vitamin A deficiency leads to growth cessation, night blindness, xerophthalmia, keratomalacia and ultimately to complete loss of vision. The recommended daily intake of retinol equivalents for adults is approximately 750 mcg (1 mcg retinol equivalent = 1 mcg retinol or 6 mcg carotene).

Vitamins are organic substances that are necessary for the normal functioning of the body. They cannot be produced by the body and must be obtained from food to maintain health. There are two types of vitamins: water-soluble and fat-soluble. Water-soluble vitamins dissolve in water, while fat-soluble vitamins dissolve in fats.

Vitamin A is a fat-soluble vitamin that is essential for maintaining healthy bones, vision, and mucous membranes. It is found in dairy products, eggs and animal liver, as well as some plant foods such as carrots and cabbage. Vitamin A is formed from carotene, a pigment found in plants.

A lack of vitamin A can lead to various diseases, such as night blindness, osteoporosis and diseases of the mucous membranes, such as ulcers and erosions. Therefore, it is important to eat enough foods containing vitamin A to maintain your health.

Fat-soluble vitamins such as vitamin D, vitamin E and vitamin K are also essential for a healthy body. Vitamin D helps absorb calcium and phosphorus, which are essential for strong bones. Vitamin E protects cells from free radicals and maintains healthy skin. Vitamin K is involved in blood clotting and wound healing.

Water-soluble vitamins, including B vitamins and vitamin C, are also important for health. B vitamins help convert food into energy, and vitamin C is essential for healthy skin, bones and the immune system.

In general, vitamins are essential nutrients needed to keep the body healthy and functioning properly. Eating a variety of vitamin-rich foods helps provide the body with essential nutrients.

A vitamin is a biologically active substance necessary for the normal functioning of the body. Most vitamins enter the body only with food, since they are not synthesized in living cells. Vitamin deficiency can cause various diseases in people.

The first vitamin studied in medical history is vitamin A (also known as retinol). Retinol is part of the group of fat-soluble vitamins and plays an important role in the human visual system. It is important for the growth and development of bones and the lining of the stomach and respiratory tract. Retinol deficiency can lead to decreased vision, slower growth and physical development, and damage to visual tissue. Retinol is obtained from animal products such as egg yolks, fish, liver and dairy products. In addition, some fruits and vegetables contain carotene, a provitamin from which retinol is formed in the body. The recommended daily intake of retinol is about 700-900 micrograms for an adult.

Another group of vitamins includes water-soluble vitamins. For example, vitamin B12 and vitamin C are water-soluble vitamins that help maintain normal body health and protect against infections. Insufficient intake of these vitamins can lead to anemia and a weakened immune system, respectively. Water-soluble vitamins require the presence of water in food to be absorbed. Vitamin C mainly finds its use in neutralizing free radicals and other harmful substances in the body. Vitamin B12 is a cofactor in the nucleotide synthesis cycle and supports nervous system health. Vitamin C has been well studied through its widespread use in medicine, and research has shown that adequate intake can help protect the body from oxidative stress. Studies have shown a significant reduction in the risk of myocardial infarction and other cardiovascular diseases
