Vitamins are important for the normal development of the body. Everyone should be aware of the consequences of vitamin deficiency and the proper use of essential vitamins.
Vitamin A (retinol) is involved in the formation of visual pigments and helps the eye to adapt to different levels of light.
However, when the body lacks retinol, it initially loses its ability to adapt to darkness, and develops blindness and inability to look at light. The skin becomes dry and white, itchy, purulent skin diseases develop, and the hair begins to dry out and fall out.
Vitamin A is found in the green leaves of plants, especially spinach, parsley, chives, lettuce, apricots, carrots and fish oil.
Vitamin V3 (nicotinic acid) gives life to cells, allows them to breathe, participates in protein metabolism, accelerates the digestion of plant proteins in the body, improves the composition of the juice produced by the pancreas, normalizes liver function.
When nicotinic acid is deficient, a person develops a disease called pellagra. It causes diarrhea, redness and glistening of the tongue, and red spots on the limbs. There is dryness, headache, lethargy, loss of consciousness, nervousness, and even frequent mood swings and poor sleep.
Nicotinic acid is found in large amounts in the liver and kidneys of cattle, vegetables and fruits, buckwheat groats, chicken and veal.
Vitamin K (phylloquinone) deficiency causes bleeding under the skin, muscle tissue and mucous membranes. A person usually needs 100 milligrams of vitamin K a day. This vitamin is synthesized by microorganisms in the upper part of the colon.
Vitamin D (calciferol) affects metabolism and bone formation. It is necessary for the rapid growth of the skeleton. If this vitamin is deficient, children develop rickets, become weak, sweat a lot, have frequent colds, and have delayed teething.
In adults, vitamin D deficiency can lead to lethargy, fatigue, and pain in the pelvic bones and muscles. Even the bones become soft, which can have serious consequences. Lack of this vitamin also disrupts the absorption of calcium in the intestines.
Vitamin V6 (pyridoxine) regulates the activity of the nervous system, prevents anemia.
Pyridoxine deficiency is especially dangerous for pregnant women. Because in this case, the toxicosis in them begins early and intensifies.
Pyridoxine is found in small amounts in peas, potatoes, beets, beef and chicken. In fact, it is caused by intestinal bacteria. If antibiotics are taken due to an illness, the intestinal microorganisms are damaged and the pyridoxine is further reduced. Therefore, after taking antibiotics, it is advisable to take vitamin V6 with a doctor's permission.
