What is Vitamin B12?

Vitamin B12, or cobalamin, is a very important vitamin that is water-soluble. It plays a very important role in the metabolism of every cell in the human body. That means it is very important for our health.

Vitamin B12 synthesis can take place in the intestines of animals, including ours. However, we will eliminate vitamin B12 on our own after synthesizing them. That means we cannot absorb vitamin B12 on our own.

Therefore, we need to look for vitamin B12 from other sources.

We only need about 3 micrograms of vitamin B12 per day. However, a deficiency of B12 will lead to many serious consequences. You will even face the risk of death if you are deficient in this vitamin.

As a result, it is best to make sure you get the right amount of vitamins.

A vegetarian diet can make you deficient in this vitamin. Therefore, you need to supplement with products rich in B12 as well as special supplements to avoid deficiency of B12.

Reasons vegetarians don’t get B12

Plants or animals themselves do not synthesize vitamin B12. What makes vitamin B12 are microorganisms (bacteria).

Currently, the excessive use of pesticides has led to many serious consequences. One of them is that it kills all beneficial bacteria, including the kind that makes vitamin B12.

Vegetarians do not eat animals. Therefore, they tend to have less vitamin B12 than other people. However, that does not mean that eating meat can prevent this vitamin deficiency. Both vegetarians and non-vegetarians are at a very high risk of B12 deficiency.

In the past, we could even get B12 by drinking water. However, people have used chlorine to disinfect our drinking water. As a result, the water also no longer contains this important nutrient.

Where can you find vitamin B12?

Vitamin B12 is a water-soluble vitamin. You can find B12 in several foods. Bacteria are what synthesize this vitamin. These bacteria are usually found in the intestines of animals or the soil.

We can see this most clearly in the results of the National Health and Nutrition Examination Survey. Specifically, about 3.2 percent of adults over the age of 50 have severely low B12 levels. In addition, 20 percent of them have mild B12 deficiency.

In general, vitamin B12 deficiency is not a problem unique to vegetarians. It’s a common problem for everyone.

We produce vitamin B12 in our intestines. Unfortunately, our blood cannot absorb them. Our body will eliminate them on its own.

As for wild animals, even if they only eat plants, they are not deficient in vitamin B12. The reason is that when they eat plants, they will accidentally ingest excrement and soil that contain B12. We can’t all do that, can we?

Symptoms that indicate you are deficient in B12

A deficiency of B12 can cause anaemia or serious neurological effects. This is often the case with long-term vegans who do not take the usual B12 fortified foods.

In addition, infants are also at risk of B12 deficiency when consuming the milk of vegetarian mothers with low B12 levels.

Adult, when they have a B12 deficiency, they usually have the following signs:

  • Weak
  • Heartbeat fast
  • Constipation
  • Anorexia
  • Tired
  • Diarrhea
  • Hair loss
  • Shortness of breath
  • Muscle weakness
  • Constipation
  • Decreased eyesight
  • Memory decline
  • Depression

For infants, a B12 deficiency leads to much more serious consequences. They may lose energy, have an appetite, and slow to grow.

If this continues for a long time, they can go into a coma or even die. Infants are more vulnerable than adults. Some can make a full recovery, others face developmental delays.

How much B12 do we need each day?

There is no exact answer to this question. It has significant differences between countries.

For the United States, the recommended daily intake of B12 is 2.4 micrograms for the average adult. This number is 2.8 micrograms for nursing mothers. For Germany, each person needs to supplement with 3 micrograms of B12 per day.

For both vegetarians and non-vegetarians, achieving adequate B12 intake is very easy. You can use many methods to supplement B12 that suit personal preferences.

According to the Vegetarian Association, you need to take the following actions to be able to get enough vitamin B12:

  • You should take fortified foods two or three times per day. That’s to make sure you are getting at least three micrograms of B12 each day.
  • You should take a B12 supplement daily. With that, you can get ten micrograms
  • You should take a B12 supplement weekly to get at least 2,000 micrograms

Do not worry about you getting too much vitamin B12 a day. Your body will excrete excess B12 through urine.
