Vitamin B12 (cobalamin) is one of the most essential components of the B vitamin complex for your health and well-being.

Why is vitamin B12 necessary for your body?
In addition to being necessary for red blood cell production, vitamin B12 is also an essential catalyst for DNA and neurotransmitter production. If you don’t eat enough vitamin B12, your DNA will degrade, your lifespan will shorten, you’ll become anaemic, and you’ll develop psychiatric conditions.
Functions of vitamin B12
Blood cell production: Your body needs vitamin B12 to produce red blood cells, which are the primary components of your blood that carry energy throughout your body.
DNA production: Without vitamin B12, your body won’t be able to synthesise DNA, and reduced DNA synthesis interferes with cell replication and reduces your longevity.
Neurotransmitter production: Vitamin B12 is vital for the production of most neurotransmitters. You’ll develop psychiatric conditions and have trouble with focusing and memory if you don’t get enough of this nutrient.
Bone density benefits: People who don’t consume enough vitamin B12 are more at risk of osteoporosis.
Symptoms of vitamin B12 deficiency
The most common symptom of anemia, which can be caused by B12 deficiency, is fatigue. Anemia can also cause muscle weakness and fainting.
Decreased red blood cell count caused by anemia can make you look pale and sickly.
Increased Heart Rate
To make up for the decreased levels of red blood cells caused by vitamin B12 deficiency, your heart might start to beat faster. This increased strain on your heart increases your risk of cardiovascular disease, and it can also cause inflammation in your blood vessels.
How long do you need to take vitamin B12 to start experiencing its benefits if you’re deficient?
It’s generally possible to start seeing some improvements in vitamin B12 deficiency immediately after you start supplementing with this nutrient. Prolonged deficiency in B12, however, can cause serious medical conditions that take a long time to recover from.
How long does it take for your body to digest/absorb vitamin B12?
While your body absorbs vitamin B12 quickly, this nutrient isn’t absorbed as efficiently as some of the other components of the B vitamin complex. Some sources indicate that your body only absorbs about 50% of the vitamin B12 you consume, and this absorption rate drops off even further when you consume more B12 than your body can process.
How long does vitamin B12 stay in your body after you take it?
Vitamin B12 doesn’t generally build up in your bodily tissues. In the case of severe overdose, however, this substance might build up to dangerous levels.

Avoid these symptoms by only consuming your RDA of this essential nutrient.

Why might synthetic forms of vitamin B12 be better?
As compared to the natural form of vitamin B12, methylcobalamin, cyanocobalamin is more stable and cost-effective.
Absorption rate of synthetic vitamin B12
All available data indicate that methylcobalamin and cyanocobalamin have roughly equal absorption rates.
Why might natural forms of vitamin B12 be better?
There are no known advantages of consuming natural forms of vitamin B12.

Vitamin B12 trends in medicine
A 2019 study found that deficiency in vitamin B12 leads to increased likelihood of infection with pathogens. This research examines the hitherto largely unexplored relationship between vitamin B12 and your immune system, and it simply underscores the importance of incorporating plenty of this essential nutrient into your diet.
Why everyone should be taking WeAreFeel supplements
While vitamin B12 is one of the most important essential nutrients, it’s also one of the nutrients you’re most likely to be deficient in. Vegetarians and vegans are particularly at risk of vitamin B12 deficiency; part of the reason that so many people who don’t eat animal products are anaemic is that they don’t get enough vitamin B12. Simply taking an iron supplement won’t help with your anemia if you don’t incorporate more vitamin B12 into your diet.
At the same time, you don’t want to overdo it with this nutrient. The U.S. Food and Drug Administration (FDA) recently reduced the RDA for vitamin B12 from 6mcg to 2.4mcg, which just goes to show that recent research has been bringing attention to the dangers of taking too much of this nutrient.
