How Vitamin B12 Works

Most people know that it is important to keep your body nourished and that it may be a good idea to take a daily multivitamin. That’s as far as most people go in terms of knowing the specific benefits of a well-rounded, healthy diet or vitamin supplements.

How vitamin B12 can help your health

For instance, it is fairly common knowledge that B-vitamins are helpful in maintaining energy levels and managing stress.

However, Vitamin B12, in particular, has also been linked to brain health. Find out how vitamin B12 can help your health below.

How is Vitamin B12 Important for Healthy Brain Function?

Memory and Focus

When considering what functions represent a healthy brain, quick-thinking, memory, or focus may come to mind. It is true that healthy levels of vitamin B12 have been linked to all of these things. Vitamin B12 is also necessary for proper nerve function, and the brain and nervous system work closely together.

How Vitamin B12 Can Improve Your Brain Health TodayThe myelin sheath that surrounds nerve cells is responsible for how quickly signals move through your brain, and vitamin B12 is vital for maintaining the strength of the myelin sheath.

Therefore, maintaining a consistent amount of vitamin B12 in your body will increase the speed of your thinking, aid memory, and increase focus.

Formation of Blood Cells

Vitamin B12 plays a vital role in the production of red blood cells. When you have a deficiency of vitamin B12, red blood cells tend to be large and oval, as opposed to healthy blood cells which are small and round.

When red blood cells are too large and irregular in shape, they cannot move readily through your bone marrow, causing anemia.

In turn, when you are anemic, there aren’t enough red blood cells to transport oxygen to your brain and other vital organs.

Elevated Mood

Sufficient levels of vitamin B12 also aid in the synthesizing and metabolizing of serotonin, a chemical produced naturally by your body that regulates mood.

Therefore, a deficiency in vitamin B12 can cause a depressed mood or further lower the mood of those with chronic depression.

Sources of Vitamin B12


The only way to obtain vitamin B12 naturally is via a diet high in animal-based foods such as meats, poultry, organ meats, fish, eggs, and dairy products.

Generally, vitamin B12 is not found in plant foods, but most breakfast cereals are fortified with vitamin B12, making them a good source of vitamin, especially for vegans and vegetarians who are otherwise not getting vitamin B12 from their diet.


Taking a daily multivitamin or getting B12 injections are other ways to ensure that you are getting enough vitamin B12, especially if you follow a vegetarian or vegan diet.

In addition, vitamin B12 supplements come in the form of sublingual tablets or lozenges, which increase the absorption rate of the vitamin.

B12 Vaporizers

A new and exciting way to get your vitamin B12 is by inhaling it. Yes, inhaling it! Vitamin vape pens have become a popular way to maintain sufficient levels of vitamin B12 throughout your day and to prevent the vitamin B12 deficiency.

Nicotine-free vape pens are now on the market, and they are a very affordable and effective way to get your vitamin B12. Each vitamin vape pen contains hundreds of puffs and can easily be transported in your purse or pocket.


Maintaining healthy levels of vitamin B12 is crucial for a healthy brain.

By increasing your daily intake of vitamin B12 by way of diet, supplements, or a vitamin B12 vaporizer, you can improve the function of your brain and nervous system, leading to increased memory, focus, and energy levels, as well as an elevated mood.
