Vitamin is one of the essential ingredients in the body and Vitamins are organic compounds that are needed in small quantities to sustain life. Most vitamins need to come from different foods

This is because the human body does not produce enough vitamins, so it is necessary to meet the needs of vitamins by taking different foods. 

Each organism has different vitamin requirements. For example, humans need to take vitamin C or ascorbic acid, but dogs do not eat it. Dogs can synthesize or produce enough vitamin C for their own needs, but humans cannot. 

People need most of their vitamin D to be exposed to sunlight, as it is not available in sufficient quantities of food. However, when exposed to sunlight, the human body can synthesize. 

Different vitamins have different roles and they need different amounts. 

What are vitamins? 

Vitamins are a group of organic substances that are present in minute quantities in natural foods. It is essential for general metabolism. If we do not eat enough vitamins of any kind, certain medical conditions can result. 

A vitamin is both: 

  • An organic compound, which means it contains carbon. 
  • An essential nutrient that the body cannot produce sufficiently and which needs to be obtained from the diet.
  • There are currently 13 recognized vitamins. 

Fast facts on vitamins 

Here are some key points about vitamins. More detailed and helpful information in the original article. 

  • There are thirteen (13) known vitamins. 
  • Vitamins are either water-soluble or fat-soluble. 
  • Water-soluble vitamins are harder to store for the body than fat-soluble
  • Vitamins always contain carbon, which is why they are described as “organic”. 
  • The best source of vitamins is food, but some people may be advised to use the supplement by a physician. 


Vitamins are a substance that is essential for normal cell functioning, growth, and development 

Here are 13 essential vitamins. This means that the vitamins are needed for the body to function properly. They are: 

  • Vitamin A 
  • Vitamin C 
  • Vitamin D 
  • Vitamin E 
  • Vitamin K 
  • Vitamin B1 or thiamine 
  • Vitamin B2 or riboflavin 
  • Vitamin B3 or niacin 
  • Vitamin B5 or Pantothenic acid  
  • Biotin (B7) 
  • Vitamin B6 
  • Vitamin B12 or cyanocobalamin 
  • Folate (folic acid and B9) 

Vitamins are divided into two categories: 

  • Fat-soluble vitamins are deposited in the body’s fatty tissue. The four fat-soluble vitamins are A, D, E, and K. 
  • There are water-soluble vitamins here. They do not accumulate in the body. Any residual water-soluble vitamin leaves the body through urine. Although the body maintains a small reserve of these vitamins, it should be taken regularly to prevent the body’s deficiency. Vitamin B12 is the only water-soluble vitamin in our body that can be stored in the liver for many years. 

Some “vitamin-like factors” are also needed by the body such as:

  • Choline  
  • Carnitine 


Each of the vitamins listed below has an important function on the body. Vitamin deficiency occurs only when you do not get enough of a certain vitamin. Vitamin deficiency can cause health problems. 

  • Not eating enough fruits, vegetables, beans, lentils, whole grains and delicious dairy foods can increase your risk of health problems, including poor health (osteoporosis) for heart, cancer, and bone. 
  • Vitamin A helps to form and maintain healthy teeth, bones, soft tissues, mucus membranes, and skin. 
  • Vitamin B6 is also called pyridoxine. Vitamin B6 helps in the formation of red blood cells and maintains brain function. These vitamins also play an important role in proteins that are part of many chemical reactions in the body. 
  • Like other B vitamins, vitamin B12 is very important for metabolism. It helps in the formation of red blood cells and maintains the central nervous system. 
  • Vitamin C, it’s also called ascorbic acid, is an antioxidant that promotes healthy teeth and gums. It helps the body absorb iron and maintain healthy tissue. It is also necessary for wound healing. 
  • Vitamin D is also known as “sunshine vitamin” since it builds up the body after sunlight. 10 to 15 minutes of sunshine 3 times a week is enough to produce the body’s vitamin D requirements for most people at most latitudes. Not enough people who are not exposed to sunlight can not produce enough vitamin D. D Vitamin helps the body absorb calcium. You need calcium for the normal development and maintenance of healthy teeth and bones. It helps to maintain the correct levels of calcium and phosphorus blood. 
  • Vitamin E is an antioxidant, it’s also known as tocopherol. It helps the body to form red blood cells and utilize vitamin K 
  • Vitamin K is needed because without it, blood will not stick together (clogged). Some research suggests that this is important for bone health. 
  • Biotin is essential for the metabolism of proteins and carbohydrates and the production of hormones and cholesterol. 
  • Niacin is a B vitamin that helps maintain healthy nerves and skin. High levels have a cholesterol-lowering effect. 
  • Folate helps in the formation of red blood cells with vitamin B12. It is required for DNA formation, which regulates tissue growth and cell viability. Any woman who is pregnant should be sure to get enough folate. Low levels of folate are associated with spina bifida with congenital defects. Many foods are now protected with folic acid. 
  • Pantothenic acid is essential for the metabolism of foods. It also plays a role in hormone and cholesterol production. 
  • Riboflavin (Vitamin B2) works with other B vitamins. It is important for the growth of the body and the formation of red blood cells. 
  • Thiamine (Vitamin B1) helps the body’s cells to convert to sugar. During pregnancy and breastfeeding, it is very important to have adequate sugar intake. It is also essential for heart function and healthy nerve cells. 
  • Choline aids the normal functioning of the brain and nervous system. Lack of choline can lead to swelling in the liver. 
  • Carnitine helps the body convert fatty acids into energy.
