What Is Primary Role Of B-Vitamins? In our Body and Their Functions

What Is The Primary Role Of The B Vitamins

What Are Vitamins?

Vitamins are related to organic compounds that are responsible for proper body physical working. These vitamins are need relatively in lower concentrations as compare to other nutrients. They play a vital role in our body system for its proper working. Those are not produced in the body. Instead, they are necessarily taken into the body in small quantities by daily diet. The human body needs to have 13 vitamins in total, in which

Four vitamins are fat-soluble, i.e., Vitamin (A, D, E, K )

Nine vitamins are water-soluble, which are named B-Vitamins. These are given below.

  • Thiamine (B1)
  • Riboflavin (B2)
  • Niacin( B3)
  • Pantothenic acid (B5)
  • Vitamin (B6)
  • Folate (B9)
  • Vitamin (B12)

Origin of B-Vitamins

As far as their origin is concern, these are synthesize by the plants. They perform the same cellular functions in the plants as they do in animals who eat those plants. Unlike other B-vitamins, Vitamin B12 is synthesize by bacteria.

Nowadays, most of them are taken from plants. But we can consume them indirectly by food chains of animals, which are as follows:

  • Eggs
  • Meat (including mutton, beef etc.)
  • Dairy products

Primary Role Of B-Vitamins

The primary role of B-Vitamins includes brain functioning, cellular energy level, and metabolic process maintenance.

  1. Bodily Performances

They play a primary role in metabolic functions. Let’s take an example of vitamin B3, which plays a vital role in enzymatic reactions. During its bodily action, it is convert into nicotine amide adenine diphosphate (NAD) and oxidize into NAD+.

In the electron chain of mitochondria, NAD releases its electron to protein. The transfers of electrons happen through the chain and proton gradient across the mitochondrial membrane. Resultantly, this protein gradient compels the conversion of adenosine diphosphate (ADP) to adenosine triphosphate (ATP), and ATP starts to provide permanent energy to cells for metabolic activity.

  1. Regulation Of Plasma Homocysteine

The B-vitamins which we intake with our diet play a vital role in the regulation of plasma homocysteine. Apart from vitamin B12, all other B-vitamins are full of dietary intakes, which keeps the elevation in homocysteine.

It is related to an increase in cardiovascular disease, which needs to be suppressed. This regulation includes the primary role of B-vitamins.

  1. Cognitive Function Among Old People

In general, research to date indicates that cognitive function and cognitive impairment among older adults are link to B vitamins. However, there is a great deal of space for more research into B vitamins’ impact on cognition. Cross-sectional, correlational designs have appeared to be used in the prior study.

The results of studies using these prototypes thus providing a significant basis for concluding that B vitamins may be correlated with cognitive performance. Well-conducted intervention trials may be usefully complemented by cognitive impairment in aging. In the design of studies in general and intervention studies in particular, several factors would lead to our ability to determine micro-nutrients’ role in older cognitive performance.

  1. Energy Production

The primary role of B-vitamins includes in the energy production of the cells via the catabolic process. If there is a deficiency in any of the eight vitamins, this process might get affected. So, it will not be wrong to say that these vitamins have importance, just like the backbone in cellular energy.

In this process, the close-connected relationship between mitochondria and B-vitamins via electron transport chain and the citric acid cycle. So, the primary role of B-vitamins includes energy production and proper consumption within the body.

  1. Brain Maintenance

The brain in the human body has primary importance in the human body as it controls all activities in our body. Its average performance is as essential as the backbone is to stand on feet. It is the most active metabolic organ of the human body, consisting of only 2% of the body weight, but its energy consumption is around 19-20%.

The neurochemical synthesis by these vitamins is consider equally important as its proper working concerning to body from head to toe. The brain’s mechanism keeps changing with the brain’s needs and requirements, but the regulation in mechanisms kept higher to make sure the brain’s concentration is relatively higher.

  • Thiamine includes necessary steps in the production of fatty acids, steroids, and nucleic acid. They act as a precursor to bioactive compounds for regular brain activity. Its role is essential as a co-factor in metabolic processes.
  • Riboflavin co-enzymes includes the production of niacin regarding its conversion, manipulation. Likewise, they are quite crucial for the synthesis of hemeprotein, including hemoglobin. These proteins are necessarily be undertaken to transfer electrons and transportation of oxygen along with its storage.
  • Pantothenic acid works as a substrate for the synthesis of Ubiquitous co-enzyme. While in the production of neurotransmitters, it also becomes a rate-limiting co-factor.
  • Folate and vitamin B12 jointly play a role in folate and methionine cycles. As the deficiency of vitamin B12 becomes hazardous for brain working and controlling capabilities. The brain’s interconnection with the brain is affected.

So, it might be conclude that B-vitamins play a primary role in brain functioning.

What Are The Sources Of B-Vitamins?

  1. Thiamine

Its basic sources include

  • Peas
  • Nuts
  • Cereals
  • Vegetables

It helps the nervous system work properly and take energy from food during the digestion process in the human body.

For men (age 19-64), 1mg in 24 hours.

For women (age 19-64), 0.8mg in 24 hours.

A high dose of this vitamin creates several problems. It is not stored in our body, so we need to consider it as per necessity.

  1. Riboflavin

Its basic sources are include

  • Milk
  • Dairy products
  • Curd

These should be taken in the absence of light as they might get destroyed by sunlight.

For men (age 19-64), 1.3mg in 24 hours

For women (19-64), 1.1mg in 24 hours.

They can also not be stored in our bodies, so we need them in our daily lives. Its less or massive amount into the human body causes severe problems within the system.

  1. Niacin

Its basic sources are include

  • Meat
  • Flour
  • Dairy products

For men (age 19-64), 16.5mg within 24 hours

For women (age 19-64), 13.3mg within 24 hours

It is not stored, so we need to consume it on a daily diet.

Its high consumption causes liver problems, while low consumption causes skin scratches.

  1. Pantothenic Acid

Its sources are include

  • Meat (including chicken, mutton and beef)
  • Liver
  • Kidneys
  • Dairy products
  • Mushrooms

More or less 200mg consumption of pantothenic acid is necessary for our body. It is stored in our body, so we need to take it into our daily life diet.

  1. Vitamin B6

It helps the body to gain and its proper usage from protein as well as extraction of carbohydrates from food. It sources are includ

  • Peanuts
  • Soya beans
  • Milk products

For men (age19-64), 1.4mg within 24 hours

For women (age19-64), 1.2mg within 24 hours.

Its permanent extended high usage turns into permanent problems.

  1. Biotin

To make fatty acids it is quite important for body.

It source are include

  • Food products but at lower levels

0.9mg per day, it should be taken by men and women.

  1. Folate And Folic Acid

Folate helps to make red blood cells within the body and reduce the risk of birth defects like unborn babies.

Good sources include

  • Peas
  • Breakfast cereals consisting folic acid.

200mg per day is necessary for adults. It is highly recommend for pregnancy up to 400mg per day. But too much usage can harm the nervous system.

  1. Vitamin B12

Its good sources are include

  • Dairy products
  • Cheese
  • Fish
  • Meat

Adults need 1.4mg per day usage of vitamin B12.

It can causes bodily defects if taken into less amount.

End Note

Vitamin B is necessary to consume daily to work correctly for the human body. Its primary role is vital for healthy physiological activities with adequate supply and energy consumption within the cells. Additionally, brain functioning is as equally important as the previous ones. So, the inter-related relationship within different organs maintains by the essentially needed these B-vitamins.
