Have you ever wondered why Vitamins are important to us? Why do health nuts go gaga over them?
The word “Vitamin” is a short version of Vital Amine. Amines or Amino acids are the building blocks of proteins. Vitamins are organic compounds that are essential in minute quantities. They support the body’s various physiological functions. These organic compounds cannot be synthesized by the body. Which is why they need to be supplemented through our foods on a regular basis to meet our needs.
Vitamins have three main characteristics:
- They are naturally available in the foods we eat, usually present in very small quantities.
- They are essential for normal physiological functions of the body – digestion, growth and reproduction.
- When we do not consume vitamins in sufficient quantities, the body exhibits deficiency symptoms.
Based on its solubility Vitamins are divided into two types:
- Vitamins that dissolve in fats or lipids are called lipid soluble vitamins. Fat-soluble vitamins are absorbed passively into the body and must be transported along with dietary fat. These are usually found in cells which contain fat such as membranes, lipid droplets or oils within seeds. In the body, these vitamins are stored in the fatty tissues.
- Vitamins soluble in water are known as water-soluble vitamins.
Each of these super awesome vitamins serve multiple functions in the human body. But the most crucial among them is the role they play with Enzymes. Vitamins are absolutely necessary as cofactors for enzymes to catalyse reactions. And every process in the body depends on these enzymes.
When the body does not receive vitamins in the right quantities on a regular basis, there are deficiencies. These can create or worsen chronic health conditions.
Water Soluble Vitamins:
The functions of some of the vitamins are very similar to one another and are found in similar foods. One such group of vitamins is referred to as the B complex. These include 8 B vitamins – B1, B2, B3, B5, B6, B7, B9 and B12). These vitamins, as a group, play an important role in keeping our bodies functioning like well-oiled machines. While each of these vitamins work in tandem, they also have their own unique roles and functions within the body including
They are usually found together in different food groups. Each of them plays vital roles and ensure that the body operates efficiently, as it should!

Vitamin B12 (Cobalamin):
Vitamin B12 must combine with intrinsic factor before it’s absorbed into the bloodstream. We can store a year’s worth of this vitamin – but it should still be consumed regularly. B12 is a product of bacterial fermentation, which is why it’s not present in higher order plant foods.
Unlike other vitamins, Vitamin B12 is a total team player. B12 combines with B9 to help iron-protein complex aka haemoglobin do its job, ie carry oxygen. Since B12 is a product of bacterial fermentation, it is not present in higher order plant foods.

From then on this Vitamin was closely studied they found that Vitamin does wonders in treating a whole range of ailments. This water-soluble vitamin easily gets destroyed when fresh foods are processed. In the body, Vitamin C acts as a strong antioxidant (7). It stimulates the production of hormones & enzymes.
