Why are Vitamins important | Vitamins in Biochemistry

Why are Vitamins important?

Vitamins are necessary growth factors. The body cannot synthesize vitamins, which are organic molecules, thus our bodies need to consume them every day for health, growth, and life.

  • F.G. Hopkins, a British scientist, used experiments to demonstrate that our body also needs other nutrients besides carbs, proteins, and fats for survival and good health.
  • A Latin phrase called vita, which means life, was coined by a Polish biochemist (Casmir funk) to describe these deficient elements.
  • Thus, vitamins are essential growth elements, to put it briefly.

Importance of Vitamins:

  • Vitamin A, which is present in our eyes, helps us see by transporting visual data from the eye to the brain. It also provides the cornea of the eye with a moist nature.
  • Vitamin C strengthens our immune system and aids in blood production.
  • The control of nerve impulse transmission and the synthesis of haemoglobin are both aided by vitamin B. Additionally, some 100 enzymes are activated by vitamin B.
  • Vitamin D strengthens bones and teeth. It controls the amount of Ca in our blood.

Types of Vitamins

Classification of Vitamins on the basis of solubility:

The solubility of vitamins determines which of two categories they fall into. Below are the two types of vitamins:

  1. Fat-soluble vitamins
  2. Water soluble vitamins

Fat Soluble Vitamins:

  • The term “fat-soluble vitamins” refers to vitamins that are soluble in fat.
  • Fat-soluble vitamins should only be used in accordance or as directed by your doctor because excessive intake can have negative effects, such as vitamin-A overdose causes:
  • Irritability
  • Dry skin
  • Pressure inside head or headache

Overdose of vitamin D cause:

  • Bone pain
  • Joint pain
  • Kidney pain
  • Loss of weight

Examples of fat-soluble vitamins are; vitamin-A, vitamin D, vitamin E and vitamin K.

Water Soluble Vitamins:

  • Water-soluble vitamins are those that are soluble in water.
  • Any excess water-soluble vitamins you consume will be expelled by your body.
  • However, even at excess doses, they are not hazardous.
  • Examples are vitamin-B and vitamin C.


Vitamins such as vitamins B and C, are soluble in water. When the foods that contain these vitamins’ natural sources—such as rice, pulses, beans, gram, and peas—are boiled in water before being drained. Water will cause vitamins B and C to dissolve, and they will sink with the water that is drained.

Vitamins may be helpful for your child if you feed them a special diet, they have trouble absorbing nutrients, or they are finicky eaters.

  • Consult a doctor before giving your child any kind of supplement.
  • Check for certifications from organisations like NSF International, the United States Pharmacopeia,, Informed Choice, and the Banned Substances Control Group while shopping for dietary supplements.
  • Select children’s vitamins that do not contain megadoses that go beyond what children require on a regular basis.

Precautions to Take When Giving Your Child Vitamins and Minerals

When consumed in large quantities, vitamins and minerals from supplements can be harmful to children. Those fat-soluble vitamins A, D, E, and K are especially susceptible to this, as they are stored in adipose tissue .

As a result of their candy-like appearance and flavour, gummy vitamins in particular might lead to accidental overconsumption.

Vitamins should be kept out of the reach of small children, and older children and adolescents should be educated on the proper dosage to avoid accidental overdosing.
