Frequently Asked Questions On Vitamins:
What are vitamins?
- Vitamins are organic substances necessary for the body to function properly.
- Vitamins perform the most important functions – they regulate metabolic processes, catalyze biochemical reactions, and help in the absorption of many mineral components.
- With a deficiency of vitamins, various metabolic disorders develop, which lead to malfunctions in the body and the formation of pathologies.
- Deficiency occurs when there is a violation of their intake into the body or problems with their absorption and assimilation.
How vitamins are classified?
- Vitamins are divided into water-soluble and fat-soluble vitamins.
- Water-soluble vitamins are practically not stored in the body, except B12, which is stored in the liver tissues. Given their good solubility in water, these are actively involved in metabolism and excreted in the urine, their overdose practically does not occur, even if they are taken in slightly increased dosages.
- Examples of water-soluble include groups B, ascorbic acid, P, biotin (H), etc.
- Fat-soluble vitamins are not soluble in water, they dissolve in fats, which allows them to accumulate in the body, creating a certain depot. However, this same property is dangerous because taking high doses (which is quite likely with an incorrect, independent dissection) can threaten an overdose.
- Examples of fat-soluble vitamins include retinol (A), K, tocopherol (E), and D.
- Among all the vitamins in this group, D can be partially synthesized in the body, and K is almost completely synthesized by healthy intestinal microbial flora.
- Fat-soluble vitamins are essential for health and are involved in many vital processes, including mineral metabolism, blood clotting, and sensory function.
What are the good Sources of vitamins?
- Naturally, the main source of vitamins, both water- and fat-soluble, is food. Sources of retinol will be various fruits that have a yellow or orange color, oils (both vegetable and butter), as well as animal products – eggs, milk, meat, liver, and fish oil.
- Vitamin D can be synthesized in the skin under the influence of ultraviolet radiation, and also comes with food – caviar, oily fish, meat, yolks, liver, and butter are rich in it.
- Vitamin E is found in vegetable oils, nuts, germinated cereals, seeds, herbs, heavy cream, and kinds of margarine.
- Vitamin K is produced by beneficial gut microbes and is also found in green and white vegetables (cabbage, spinach, leaf lettuce, and garden greens).
