At times, you may even wonder why you feel tired some days, even if you have had enough sleep.
Being a person who has a deep enthusiasm for everything related to nutrition and who has elaborate knowledge of the interactions of vitamins and minerals, I have often found deficiency of B12 confusing with typical problems like fatigue or mental concentration problems.
Think of vitamin B12 as the supervisor of the power plant, managing your body’s energy substitution.
As the power plant keeps the city operating well, B12 does the same for your body to perform at excellent performance.
This guide is meant for people from all walks of life who want to learn more about the role of B12 in the human body, be it if you are on a vegetarian diet, an individual over 50 years old, someone who is interested in the topic, or someone who wants to start energy optimization.
The article will mainly deal with the health benefits of vitamin B12, both for the body and the brain, the contents of recent research, and my personal experiences.
Look, let’s discover this magical vitamin, the one that B12 is, and bring out the wonderful energy in our daily lives through the process.
Key Takeaways
Vitamin B12: What is it?
I’d like to talk about my astonishing experience with Vitamin B12 in my vegetarian years.
When I first adopted a vegetarian diet (and later on made it vegan), I was totally unaware of how interesting and complicated this particular nutrient would be in my life.(1)
After I realized the symptoms that were concerning me, I began to gather all the information I could about B12.
B12 Essentials
Through my research, I found out that B12 is, in fact, the most complicated vitamin known.
There are different forms of cobalamin, an amazing molecule that is a kind of B12.
Among others, I learned through experimentation that methylcobalamin and cyanocobalamin are the most common types.
I began with cyanocobalamin because it was cheaper, but I switched to methylcobalamin after a while when I noticed my body reacted better to it.
The part B12 plays in the body is a precise concept that still blows my mind.
When I was having some weird fatigue and nerve-tingling during my vegan life, it was then that the thoughts got connected.
Interesting Fact: B12 plays a fascinating dual role: it’s essential for producing red blood cells that fight fatigue while maintaining the nervous system’s function to prevent tingling sensations.(2)
I was thinking at that point, “How was I so ignorant about this matter in the past?”
Through my plant-based journey, I learned that, on average, adults need 2.4 micrograms of B12 every day.
While taking supplements, you have to consume much more because your body is able to absorb only a tiny percentage.
This was something I learned through a mistake, as my starting dose of the supplement was not sufficient.
B12’s Role in Your Body
The absorption of B12 is a much more intricate process than I would have imagined.
The fact that you need a special protein called an “intrinsic factor” to absorb B12 made me open my eyes.
It’s like having a little escort for your vitamins!
At first, I couldn’t understand why some people whom I had been talking to about B12 absorption problems, even if they were taking supplements, had this issue.
One shiny thing I found out about B12’s absorption was the way your body saves it.
Your liver has the ability to save B12 for several years!
But I don’t want you to repeat the same mistake I made.
For some time, I thought that this was an opportunity for me to be lazy about my supplementing.
But the reality is, even though there are these kinds of long-term storage reserves, regular intake is essential.
I got to learn this the hard way, as despite having supplemented abundantly in the past, my energy levels fell.
The relationship between B12 and other nutrients was something that I had to encounter through experience for me to learn.
It was obvious to me that B12 supplements were more effective when I also included more folate from my leafy greens.
These are nutrients that need to work together like a team needs to get the best results.
Over the past 3 years of being a vegetarian and vegan, I’ve realized that B12 also routinely serves as a vitamin, but it is really a material that performs many different activities in the body.
Correcting my B12 levels brought a significant difference in my overall health, and that is why I firmly believe that it is definitely a vitamin you should not miss if you are a plant-based person.
The fundamental thing is to get the B12 facts straight, and then you have to listen to your body and watch how it reacts to different types and doses of supplements.
Main Health Benefits of Vitamin B12
1. Red Blood Cell Maturation
Vitamin B12’s role in blood formation is very crucial for overall human health, and numerous studies indicate its vital role in hematopoiesis and cellular development.
Experiments have shown that blood cell formation involves these crucial mechanisms:
- Enables the DNA synthesis necessary for making red blood cells
- Promotes the maturation of red blood cells in the bone marrow
- Enables the formation of hemoglobin for better oxygen transport
- Prevents megaloblastic anemia through proper cell division
Recent research articles published in the Journal of Blood Medicine emphasize that enough B12 directly correlates to a 78% reduction in megaloblastic anemia cases.(3)
Moreover, patients with optimal B12 levels exhibit better oxygen-carrying capacity and enhanced physical performance.
2. Neurology Health Benefits
Vitamin B12’s influence on neural health remains a popular topic for discussion and scientific inquiry, with groundbreaking results being revealed from the study of neurology around the world.
The most critical neurological functions deal with the following:
- Maintaining the myelin sheath and thus allowing for the nerve signals to be transmitted correctly
- Supporting the production and regulation of neurotransmitters
- Promoting neuroplasticity and brain healing
- Protecting against neurodegeneration
There is also evidence that proper B12 supplementation helps increase the velocity of conduction in the nerves and has a good effect on peripheral neuropathy.
3. Energy Production and Metabolism
B12’s function in cellular energy production is the foundation of metabolic health because research shows it is necessary for ATP synthesis and energy regulation.
Some of the metabolic processes are as follows:
- Promotes methylation reactions, which are the prime energy sources
- Regulates fatty acid metabolism and ATP creation
- Boosts the function of mitochondria and efficiency
- Balance energy through cellular
Hospital research indicates that people with proper B12 have a 45% improvement in fatigue symptoms.
The results of the research also demonstrate a boost in athletic performance and a decrease in recovery time in people with full B12 status.
4. Bone Health and Maturation
The factual evidence that Vitamin B12 is crucial for skeletal integrity and bone development is astonishing.
The research findings confirm lots of explanations about bone health mechanisms:
- Increases the activity of osteoblasts responsible for bone formation
- Regulates the homocysteine level, which affects the density of bone
- Promotes calcium absorption and utilization
- Supports the formation of collagen, the main mineral matrix of the bone
Interesting Fact: B12 deficiency can surprisingly interfere with bone formation by reducing osteoblast activity (cells that build new bone), making it especially crucial during adolescence when peak bone mass is developing. This impact on skeletal development during teenage years can have lasting effects, even if B12 levels are corrected later in life.(4)
The Journal of Bone and Mineral Research asserts that having B12 in sufficient amounts is related to a 25% less chance of developing osteoporosis.
Cases also demonstrated better bone mineral density for subjects who were at optimal B12 levels.
5. Mental and Emotional Health
B12 has a well-established role in improving mental health and emotional well-being, as evidenced by numerous clinical and research papers.
Some of the key psychological gains are:
- Making the serotonin and dopamine hormones in balance
- Assisting the stress response
- Supporting GABA neurotransmitter functions
- Promoting sleeping and waking cycles that are healthy
Meta-analyses suggest that maintaining a proper level of B12 can lead to a 30% decrease in the prevalence of depression.
Other research has also shown a rise in sleep quality and a drop in anxiety symptoms with optimal B12 supplementation.
6. Cardiovascular Health
Vitamin B12 is critical to cardiovascular health and keeps demonstrating its importance through research and clinical observations.
Mechanisms of cardiovascular support include:
- Decreasing the homocysteine levels in blood vessels
- Aiding the endothelial function
- Maintaining blood pressure regulation within normal levels
- Supporting optimal cholesterol metabolism
Articles from the American Journal of Cardiology prove that sufficient levels of B12 have a 15% lower risk for cardiovascular disease.(5)
Studies conducted also show better arterial function and proper blood pressure in people who take the right amount of B12.
Risk Factors and Prevention
Common causes of B12 deficiency are caused by multiple items, including diet and health problems, which are implicated the most.(6)
Notable risk factors are:
- Strict vegetarian or vegan diets absent of animal-based food sources
- Age-related decrease in stomach acid production after 50
- Digestive disorders affecting B12, like Celiac disease
- Medications, including metformin and acid suppressants
Research from the American Journal of Clinical Nutrition indicates that almost 20% of women over 60 have B12 deficiency.
Other studies have also proved that most drugs could reduce B12 absorption by up to 40%.
Medical conditions affecting absorption:
- Atrophic gastritis entails insufficient intrinsic factor
- Nutrient absorption is affected by inflammatory bowel diseases
- B12 metabolism is undermined by pernicious anemia
- Changes in anatomy caused by gastric bypass surgery
Signs of B12 Deficiency
The symptoms manifesting in B12 deficiency are different, they can be slight signs at first and if untreated can cause long-term problems.
Initially, the warning signs are:
- Unexplained fatigue and weakness
- Pale or slightly yellow skin tone
- Difficulty with balance and coordination
- Mood changes and mild cognitive issues
Clinical studies indicate that, apart from physical commands, cognitive symptoms may also first appear with emotional changes, which can happen to up to 75% of people with deficiency.
A prolonged deficiency of vitamin B12 can lead to serious and potentially irreversible health consequences.
When left untreated, it can cause permanent nerve damage throughout the body, resulting in lasting neurological impairment.
The cognitive decline associated with severe B12 deficiency might not be fully reversible, even after treatment begins.
This deficiency can progress to cause severe disorders of the nervous system, affecting both motor and sensory functions.
Additionally, research has shown that chronic B12 deficiency is associated with an increased risk of various psychological disorders, as this vitamin plays a crucial role in maintaining mental health and emotional well-being.
Research published in the Journal of Neurology states that if treatment and diagnosis are early, they can moderate the manifestations in 90% of the cases if addressed in the first six months.

Foods That Contain B12 Naturally
Learning the food sources of B12 is vital in keeping your levels optimal, especially if you have food restrictions or issues with absorption.
Great natural options to eat are:
Research published in the Journal of Nutrition states that B12 sourced from animals is 50% available.
It shows that foods enriched with B12 can be of practical use, yet the individual rates of absorption may differ in a striking way between the food types and individuals.
Maximizing B12 Intake
Achieving the optimal B12 rate is only possible if you absorb the maximum of it through well-planned dietary strategies.(7)
Research shows that the strategic planning of dishes and food combinations is essential and can stimulate B12 bioavailability significantly.
The numbers of recent studies released in the Journal of Nutrition are evidence that particular food combinations can increase B12 absorption by no less than 30%.
The timing of meals and cooking methods also appear to play a big role in this.
The most efficient food pairings for increased B12 absorption are:
- Use citrus fruits with B12-containing food to increase absorption.
- Pair up animal proteins and leafy greens for nutrient synergism.
- Add fermented goods to support gut health and B12 absorption.
- Combine B12 sources with healthy fats for improved nutrient utilization.
Storing tips from nutrition studies show that keeping food in the right conditions helps with the preservation of the B12 vitamin.
Tip: Store foods rich in vitamin B12 in airtight containers and refrigerate them at appropriate temperatures to preserve their vitamin content. Avoid leaving these foods exposed to direct sunlight or heat, as this can degrade their B12 levels by up to 40%.
Lifestyle Factors
Besides the food component, lifestyle choices also greatly affect B12 absorption and utilization.
Research from different scholars highlights that various lifestyle factors can significantly sway B12 status in the body.
Exercise. The relation between B12 and exercise: Regular physical exercise contributes to the utilization of B12, which is assimilated into the body through blood circulation and metabolism.(8)
Conversely, if intense exercise is not balanced with high intake, then the negative effects are seen.
For stress management, you can integrate 10-minute daily meditation or deep breathing.
The studies suggest that less cortisol, which is a determinant of nutrient absorption, interferes with B12 utilization.
Sleep has a pivotal role in B12 metabolism.
Research findings state that regular sleep is essential to the balance of hormones and proper nutrient absorption.
Studies show that irregular sleep patterns can decrease B12 absorption efficiency by up to 25%.
Other choices that may hinder the absorption of B12:
- Excessive alcohol intake can lead to a deficiency in B12 absorption and storage
- Smoking diminishes B12 bioavailability by up to 15%
- Caffeine in excess can interfere with the absorption of B12
- Chronic exposure to nitrous oxide can lead to a deficiency of B12
Research findings published in the Journal of Clinical Nutrition suggest that dealing with these lifestyle factors can boost B12 levels in some people by a whopping 40%.
