The 9 Major Benefits of B12: What You Need To Know

Do you feel tired, run-down, and forgetful? Are you struggling to sleep through the night? If so, you may be deficient in vitamin B12. Vitamin B12 is a vital compound, and your body needs it to stay healthy and strong.[1]

Wondering why? Keep reading to explore how B12 can help you feel more energized, improve your mood, get a better night's sleep, and so much more!

What is Vitamin B12?

The name "vitamin B12" comes from the fact that it was the twelfth vitamin to be discovered. The first 11 vitamins were discovered in alphabetical order, so B12 was named accordingly after being isolated in 1947.[4]

Vitamin B12 is a water-soluble vitamin that is essential for human health. What does that mean? Water-soluble vitamins are vitamins that dissolve in water. They are not stored in the body's fat tissues; instead, they are excreted in the urine. As a result, water-soluble vitamins, like B12, need to be consumed regularly in order to prevent a deficiency.[1-4]

The best way to get vitamin B12 is from animal products, such as meat, fish, poultry, eggs, and dairy products. However, vitamin B12 can also be found in some fortified foods, such as breakfast cereals and nutritional yeast, or people can get an easy boost of this essential vitamin through supplements.[1]

The 9 Benefits of Vitamin B12

Vitamin B12 is an essential nutrient that plays a vital role in many bodily functions. It's so important that your body actually craves it! Here are 9 of the biggest reasons why:

1. Fuel Your Body

B12 is essential for converting food into energy, so you can get through the day without feeling sluggish. Studies show a boost in energy and stamina after B12 supplementation in people with a vitamin B12 deficiency.[14,15]

Combat those afternoon slumps and get the boost you need to power through your workday or workout.

2. For a Healthy Baby

B12 is essential for fetal development, so it's important to get enough during pregnancy. Research shows that women who boost their vitamin B12 intake during pregnancy are less likely to have babies with neural tube defects.[3,7,10]

Give your baby the best possible start in life by making sure they get enough B12 from the womb.

3. Strong Bones & Healthy Vision

B12 is involved in the production of red blood cells, which carry oxygen to the body's tissues. This includes the bones and eyes, which need a good supply of oxygen to stay healthy. Studies show improvements in bone density and vision with vitamin B12 intake, as well as a reduced risk of macular degeneration.[1,11,16]

Walk tall with strong, healthy bones and healthier eyesight.

4. Boost Your Mood

B12 plays a role in the production of serotonin, a neurotransmitter that regulates mood. Research shows that the supplementation of vitamin B12 may help to delay the onset of depression and improve overall mood.[5,12]

Say goodbye to the blues and embrace regulated moods!

5. Sleep Soundly

B12 plays a role in the production of melatonin, a hormone that regulates sleep. A deficiency in vitamin B12 can lead to insomnia and other sleep problems. Studies have shown that taking vitamin B12 supplements can help improve sleep quality and duration.[1,2,13]

Sleep like a baby and wake up feeling refreshed and ready to take on the day.

6. Sharpen Your Mind and Protect Your Heart

B12 is involved in the production of myelin, a fatty substance that insulates nerve cells. This helps to protect the nerves and keep them functioning properly. Studies have shown improved cognitive function and a reduced risk of heart disease after vitamin B12 supplementation.[5,6,7,11]

Keep your heart and your brain healthy for a brighter future.

7. Get That Healthy Glow

Low levels of vitamin B12 may cause various dermatologic symptoms. Since this essential vitamin plays a role in cell production, supplementing with vitamin B12 has been shown to promote healthy hair, skin, and nails.[17,18]

Nourish your hair, nails, and skin from the inside out.

8. Get Ready to Fight Back

B12 is involved in the production of white blood cells, which are essential for fighting off infection. A deficiency in vitamin B12 can lead to a weakened immune system, making you more susceptible to illness. Studies have shown improvements in immune function after supplementing with vitamin B12.[1,2,5]

Fend off colds and the flu, and feel confident that your body can fight off infection.

9. Prevent Anemia at The Source

B12 is essential for the production of red blood cells, which carry oxygen throughout the body. A deficiency in vitamin B12 can lead to anemia, a condition in which the body doesn't have enough red blood cells.[1,2,3]

Put fatigue to rest and feel like yourself again.

Some People Need More Than What They Get From Food

So, you already know that vitamin B12 is a nutrient your body needs to keep you going. Your body needs vitamin B12 to maintain metabolism, produce DNA and red blood cells, and even keep your nervous system in tip-top shape. But, not everyone can get enough of this water-soluble nutrient from their diet.[1,2,3] 

Here are some groups of people who might require more than what they get from food:

- Older adults: As you age, your body becomes less efficient at absorbing vitamin B12.

- Pregnant or breastfeeding women: Your body needs more vitamin B12 to support the growth and development of your baby.

- Vegans and vegetarians: Vitamin B12 is found naturally in animal products, so vegans and vegetarians may not get enough from their diet.

- People with digestive issues: Some digestive conditions, such as Crohn's disease and celiac disease, can make it difficult to absorb vitamin B12.

- People taking certain medications: Some medications, such as metformin, can interfere with the absorption of vitamin B12.


If you think you might be at risk of a vitamin B12 deficiency, talk to your doctor. They can recommend a blood test to check your levels and advise you on whether you need to take a supplement.
