There are so many vitamins, you need to know what to buy – first of all, everyone should know what vitamins are!

Vitamins (also known as vitamins) are micronutrients. They are nutrients composed of organic compounds. They are important nutrients for maintaining life. Most of them cannot be produced or synthesized in the human body. They must be obtained from food. Unlike sugar, fat, and protein, which can produce calories Or energy, this substance is very important to the growth and health of cells, helps to regulate the metabolism in the body, and maintains good physiological functions of the body. Often just a small amount of vitamins can go a long way.

Vitamins can be divided into fat-soluble and water-soluble

Water-soluble vitamins (B, C) can be dissolved in water. When the intake is more than the body needs, the excess will be excreted with urine.

Fat-soluble vitamins (A, D, E, K) are only soluble in fat and must be digested and absorbed by the fat in the food. Excessive intake is more likely to cause poisoning.

Everyone is well aware that in order to maintain good health, in addition to the normal intake of various nutrients, we must also pay attention to vitamin supplements. Vitamins are a type of trace organic substances that the human body must obtain from food in order to maintain normal physiological functions. They grow and metabolize in the human body. , play an important role in the development process. Vitamins neither participate in the formation of human cells nor provide energy for the human body. The content of vitamins in the body is very small, but they are indispensable.

What are the functions of vitamins A to K?

The vitamins found in medicine can be roughly divided into two categories: water-soluble and fat-soluble. There are probably five types of vitamins that most people are familiar with: A, B, C, D, and E. Among them, vitamin A is an indispensable nutrient to protect eyes and improve vision; vitamin B is an essential part of metabolism in the human body; vitamins C and E are high-efficiency antioxidants; vitamin D can promote bone growth and remodeling. Prevention of osteoporosis in the elderly.

Natural vitamin K includes two types of K1 and K2 (there are also two types of artificially synthesized K3 and K4), and K1 is very easy to obtain from dark green vegetables. It was not until 2007 that the medical community first discovered that K2 plays a more important role in human health. An important role, K2 can control the bone regulation protein and production in bones and blood vessels. It is an important nutrient for bone health. People who are deficient for a long time will affect bone growth and even lead to bone growth stagnation.

Therefore, vitamin K2 seems to play the role of traffic police in the blood, which can direct calcium to flow back into the bones and prevent it from entering the arteries, preventing the formation of arterial calcification. If you want to achieve the goal of preventing osteoporosis and fractures, you need to supplement vitamin D and K at the same time to play a synergistic role. In Japan, vitamin K2 has become an effective therapy for osteoporosis.

In addition, one of the important functions of vitamin K is to participate in blood coagulation, so it is also called "coagulation vitamin". If vitamin K is deficient, various bleeding symptoms will appear, such as difficulty in stopping bleeding, gastric discomfort or severe diarrhea. Many dieters reduce exogenous vitamin K due to improper diet, which will cause stomach discomfort, and then reduce appetite and food intake, which may eventually lead to pernicious anemia, general weakness, inability to walk, and even aphasia.
