Vitamin B12 - Less Known, But Essential to Life

Today, a large part of the population suffers from vitamin deficiency from the B-group vitamins. Why do we have to deal with this problem? And is B12 really that important?

Get to know vitamin B12

Vitamin B12 is one of the vital substances that play a key role in the normal functioning of the human body. As the name suggests, B12 belongs to the group of B vitamins, which are essential for the normal functioning of metabolism. It supports hematopoiesis and it’s crucial to the normal function of the nervous system. However, B12 presence isn’t indicated only in terms of physical effects. It helps to keep a positive mood and to resist stress while being an important co-factor in DNA synthesis as well.

B12 represents one of the most discussed topics when it comes to a vegan diet. As its highest source is to be found in meat and animal protein generally, vegetarians and vegans are most likely to suffer from its deficiency. Although there are claims that this vitamin occurs in algae such as chlorella or spirulina, its presence in a plant-based diet has never been reliably proven.

Not only a vegan issue 

Probably the most important question remains why our ancestors had enough of vitamin B12, but we don’t.

B12 is considered to be one of the most complex vitamins we know. It wasn’t first isolated and named until 1948. Up to this point, the substance was hidden from the world, and its deficiency used to be common, even leading to death.

Vitamin B12 was originally produced by microorganisms present in the soil. From there, they entered the digestive system of animals, but also of humans.

At the beginning of the 1930s, the era of the modern economy has begun, causing an increase in agricultural productivity, associated with the first use of pesticides. However, the soil became contaminated and thus depleted all the original nutrients.

Today, not only humans but also some animals such as livestock, are supplemented with vitamin B12 in a synthetic form found in various dietary supplements to not suffer from the deficiency and to ensure their daily functioning.

What are the signs of B12 deficiency?

The most common symptoms include:

  • Anemia
  • Loss of appetite
  • Fatigue and lack of energy
  • Indigestion
  • Dizziness
  • Tingling in hands
  • Poor mobility

How can I increase its intake?

The recommended dietary allowance for vitamin B12 for adults is 2,4 μg per day. Since the best sources of the vitamin include meat, fish, and dairy, when following a vegan diet, one has to look for alternative solutions to increase the intake.

There is a number of products on the market to supply the vitamin. You can choose from a vast selection coming in different formats - from pills and capsules to liquid drops.
