What are the Types of Vitamins?

Rank Predictor

The human body needs vitamins in small amounts. Because the body produces very little or none of these vitamins, the human body needs to obtain different types of vitamins in food. Vitamin requirements are different for each organism. In contrast to humans, dogs can produce all the vitamin C they need from their bodies. Unlike most other vitamins, vitamin D is not readily available in foods for humans. The human body synthesizes vitamin D on its own when exposed to sunlight, which is the most natural source. Keeping one's health depends on the number of vitamins a person needs. Vitamins serve different functions in the body. This article can provide you with a deep understanding of the types of vitamins and minerals.

Types of Vitamins and their Functions

Vitamins are either soluble in fat or water in the body. We describe both types of vitamins below: to understand the concept of vitamins clearly, you can make your notes for types of vitamins pdf using the information given in this article.

Fat-Soluble Vitamins

Fat-soluble vitamins include vitamins A, D, E, and K. The body stores fat-soluble vitamins as reserves in the liver and fatty tissue. These reserves of vitamins can stay in the body for days and sometimes months. The body can absorb the fat-soluble vitamins from the intestinal tract through the help of dietary fats.

Water-Soluble Vitamins

All the B vitamins and Vitamin C are counted as water-soluble vitamins. Water-soluble vitamins neither stay in the body for long nor be stored. They leave the body via the urine. That is why people are required to take a more regular supply of water-soluble vitamins than fat-soluble ones.

The table will help you understand the types of vitamins and their functions.

FAQs on Types of Vitamins

1. What is the role of different types of vitamins in the human body?

Minerals and vitamins act in concert to perform hundreds of functions in the human body - making them essential nutrients. Some of the functions of vitamins in the body include strengthening bones, healing wounds, and boosting the immune system. Vitamins help turn food into energy, as well as repair damaged cells in the body. Several bodily functions depend on them, including cell reproduction, growth, and energy transport within the cell. Because you need only a tiny amount of vitamins and minerals, they are called micronutrients. Vitamins are essential for a healthy body, but they must be consumed in far smaller amounts than macronutrients, such as carbohydrates and fats. Still, inadequate intake of even these small amounts can lead to serious health problems. In the same way that the deficiency of key micronutrients can cause significant harm to your body, adequate amounts can be beneficial.

2. What are the types of vitamins needed in daily life?

Skin, muscle, and bone are all produced by your body every day. In addition to pumping rich red blood to remote outposts, it carries nutrients and oxygen to the brain and body along thousands of miles of pathways. Furthermore, it makes chemical messengers that send messages between organs, providing instructions for life. For your body to perform all of this, it needs some raw materials. At least 30 vitamins, minerals, and nutritional supplement components are essential to your body. The human body requires a combination of fat-soluble vitamins (Vitamin A, D, E, K) and water-soluble vitamins (B Vitamins and Vitamin C). B Vitamin includes Biotin (vitamin B7), Folic acid (folate, vitamin B9), Niacin (vitamin B3), Pantothenic acid (vitamin B5), Riboflavin (vitamin B2), Thiamin (vitamin B1), Vitamin B6, and Vitamin B12.
