Casually Explained: Vitamins


Hey Guys! Welcome to another video of our
“Casually Explained” series. In this series, we are talking about some scientific term which you regularly see and hear in your daily life. Today we are going to talk about Vitamins. Good health is desired by everyone & the key to achieve it is a good and balanced diet. And, when it comes to diet, the importance of vitamins cannot be ignored. Vitamins are organic compounds that our body requires in small quantity. Most of the vitamins needed by human body should be consumed from dietary sources because our body either does not produce
them enough or do not produce at all. There are 13 universally recognized vitamins – A,
B complex which contains B1, B2, B3, B5, B6, B7, B9 & B12, vitamin C, D, E & K. A point to remember here is – B4, B8, B10 and B11 were categorized as vitamins in the past but they are no longer considered as vitamins. All of these 13 universally recognized vitamins are categorized into 2 types based on their solubility fat soluble and water soluble Fat-soluble vitamins are- Vit A, Vit D, Vit E & Vit K. These vitamins are easily stored
in fatty tissues & liver. That is why our body usually does not suffer from their deficiency. And if their deficiency occurs it takes some time for the body to return at balance. On the other hand, water-soluble vitamins like Vit B complex & Vit C does not stay in the body for long. Because of their water solubility, they are easily excreted via urine. That is why regular consumption of vitamin B & C is necessary for the body. So, Why do these vitamins
important for our body? The Vitamins play a wide range of roles in our body. Some act as enzyme co-factors and help different enzymes to do their work properly. Vitamin B Complex
is a good example of this. The Vit A regulates cell and tissue growth. Vit K plays an important role in blood coagulation and it prevents cardiovascular disease. Some vitamins like Vit E & Vit C act as antioxidants. The antioxidants are essential for the protection and proper functioning of our body as we have discussed in one of our previous videos. Vitamins D have hormone-like function and it helps in the absorption of calcium and phosphorus from the diet. As you can see that the vitamins have all
these important jobs, so it is necessary to take them regularly. And if you don’t take them in proper amounts you can suffer from various diseases like beriberi, night blindness, keratomalacia, scurvy etc The Natural sources of vitamins are the best for consumption because they also provide other micro-nutrients as well as antioxidants. But you can take vitamin tablets too if necessary. Just remember one thing- like other substances
their overdose can also be harmful. So take only required quantity. Do you know what disease is caused by the deficiency of Vit E? Tell us in the comment
