Vitamin B12 as a Nootropic

Vitamin B12 as a Nootropic. Illustration of a charged-up brain sparking with natural energy.

Vitamin B12, also known as cobalamin, is a water-soluble vitamin. It is involved in the function of virtually every cell of the human body, especially affecting DNA synthesis and metabolism of fatty acids and amino acids.

Vitamin B12's far-ranging benefits across body systems help support energy, blood health, digestive function, skeletal strength and more. In this article, we're focusing on B12 for the brain.

Vitamin B12 and other B vitamins play key roles in brain health and neural function.

How does B12 work as a nootropic, specifically? Let's take a look at some of its most important bioactivities for bolstering the brain.

Brain Chemicals: Vitamin B12 is involved in catalyzing and producing neurotransmitters for cell to cell signaling such as dopamine and serotonin, which are critical for brain function and mood regulation.(1) Learn more about nootropics for neurotransmitters

Brain Protection: Vitamin B12 helps form myelin, the fatty sheath that protects and optimizes communication between all neurons in the brain.(2-4)

Brain Energy: B12 supports cell energy metabolism throughout the body, including within brain cells.(5)

Brain Blood Flow: B12 plays a role in balancing homocysteine that damages blood vessels; one study found B12 supplementation (combined with folate) reduced homocysteine by 36%.(6)

Tip: It is always a good idea to take Vitamin B12 as part of a whole B-vitamin complex.

In particular, Vitamins B6, B9 and B12 have been studied in combination and appear to be more effective for brain chemicals and homocysteine regulation when taken together.

For example, in one analysis, researchers linked Vitamin B9 supplementation (.5 mg) with a 25% reduction in blood homocysteine levels; adding B12 (.5 mcg) reduced homocysteine an additional 7%.(7)

B12 Brain Research Studies and Possible Benefits

Most of the evidence supporting B12 as a nootropic suggests failing to get enough Vitamin B12 can negatively impact the brain.

Researchers have linked suboptimal and deficient B12 levels to:(8-12)

  • memory problems and cognitive decline
  • depression, mild anxiety and even higher anxiety levels
  • Other mental health concerns including OCD
  • loss of overall brain size in the elderly

Restoring B12 to healthy levels -- via dietary changes or supplementation -- may help to reverse health issues related to sub-optimal B12 intake.

B12, Stress and Burnout: What's the Connection?

B12, Stress and Burnout: What's the Connection? A stressed out-woman in an office holding her head in her hands while surrounded with people demanding her time. She could benefit from Vitamin B12 burnout support.

Chronic stress, including workplace stress, family strife and other daily stressful situations, can negatively impact cognition and lead to a mood disorder known as burnout.

Symptoms of burnout may include:

  • Mental and physical exhaustion
  • Cynicism and detachment
  • Feelings of ineffectiveness
  • Irritability and impatience
  • Difficulty concentrating; brain fog
  • Physical symptoms (headaches, upset stomach)
  • Trouble sleeping; poor sleep quality
  • Loss of motivation
  • Withdrawal from responsibilities

Taking supplements with Vitamin B12 may help with some symptoms of burnout.

When under stress, the body may require more nutrients for various metabolic processes, including those in which vitamin B12 is involved, such as energy production and neurotransmitter synthesis.

Chronic stress can also lead to changes in eating habits and digestive issues, which in turn can affect vitamin B12 status.

For example, prolonged stress can influence the stomach's acid production, potentially leading to a reduction in the stomach's ability to properly absorb vitamin B12 from food.

While stress itself is not a direct cause of vitamin B12 depletion, its various negative effects on the body -- including producing too much cortisol (stress hormone) -- can contribute to conditions that make vitamin B12 deficiency more likely.

In one meta-analysis, researchers found that B-vitamins in supplement form, including B12, were associated with a reduction in stress and improvement in mood.(13)

With that in mind, it's important to put effort into managing and relieving stress, as well as maintaining a balanced diet rich in vitamin B12. This is especially crucial during periods of high "burnout stress."

Magnesium and adaptogen herbs like Rhodiola rosea also reduce stress and may be used as supplements for burn out.

Why supplement with B12?

Why supplement with B12? A bottle spills tablets and softgels into an open palm, including Vitamin B12 nootropic supplements for burnout.

While the majority of people consume more than the recommended amount of vitamin B12, around 20% of the elderly population in Western countries experience a deficiency of this vital nutrient. The primary reason for this deficiency in those aged 60 and above is malabsorption.

Similarly, vegans and vegetarians may face risks of B12 deficiency due to the absence of animal products in their diets.

Vitamin B12 is most commonly found in animal products, such as meat, fish, poultry, eggs, and dairy, making it particularly important for vegetarians and vegans to consider supplementation or fortified foods to ensure adequate intake.

Pregnant women and breastfeeding women, older adults, and those with certain gastrointestinal disorders are also at a higher risk of deficiency and may require supplements.

A lack of vitamin B12, or hypocobalaminemia, can adversely affect cognitive function and may lead to an increased risk of neurological disorders.

Vitamin B12 deficiency is typically diagnosed with a routine blood test.

To address vitamin B12 deficiency, especially in at-risk individuals, a healthcare professional may suggest dietary changes, supplementation or even injection of Vitamin B12.

Is a "shot of B12" an option?

Vitamin B12 shots are intramuscular injections administered by a healthcare professional to address B12 deficiency. They help people who have trouble absorbing vitamin B12 from their diet or supplements, such as those with anemia, older adults, and people with gastrointestinal health issues.

Is a 'shot of B12' an option? A hand holds a glass vial of red liquid, symbolizing a shot of vitamin B12.

The primary benefits associated with vitamin B12 shots may include an increase in energy levels, improvement in mood, and a reduction in symptoms of depression and anxiety levels, which are often associated with B12 deficiency.

Researchers have reported that for healthy individuals, supplements with high doses of vitamin b12 (1000-2000 mcg daily) may be as effective as intramuscular shots for people who are deficient.(14)

Beyond the Brain: Additional reasons to take B12

Cardiovascular System: Especially in combination with other B vitamins, it helps lower homocysteine levels. It also supports healthy endothelial function, helping to regulate high blood pressure levels.

Blood health: B12 is essential for red blood cell formation, helping to ward off the anemia that is characterized by fatigue and weakness; it also helps balance blood sugar.

Digestive Support: Facilitates proper digestion by aiding in the metabolism of fats and carbohydrates, which contributes to energy production. Also optimizes the gut for nutrient absorption.

Skeletal System: Associated with better bone health and lower risk of osteoporosis, especially in older adults, by aiding in bone mineral density maintenance.

Immune Function: May support immune system function, potentially by helping to maintain healthy and balanced immune responses to invading pathogens. Learn more about natural immune support

Skin, Hair, and Nails: Along with other B vitamins, B12 plays a role in cell reproduction, contributing to healthy skin, hair, and nails by assisting in their ongoing renewal process.

B12 forms found in supplements

Vitamin B12 supplements come in several forms, each with distinct characteristics. The common forms found in dietary supplements include:

Cyanocobalamin: Synthetic B12; common and widely used in cheaper supplements. It converts to active forms of vitamin B12 (methylcobalamin and 5-deoxyadenosylcobalamin) in the body.

Methylcobalamin: One of the two active forms of vitamin B12 found in the body. Found in foods, it is readily utilized by the body and is often recommended for those with B12 absorption issues.

Hydroxocobalamin: Naturally produced by bacteria in the gut, hydroxocobalamin is converted into active forms of B12 in the body.

Adenosylcobalamin (5-deoxyadenosylcobalamin): The other active form of B12 in the body, adenosylcobalamin, is associated with cellular energy production.

Beyond these forms are many more versions created as "branded" B12 that are used in many other supplements. It can be confusing choosing the best B12.
