B-12: The Miracle Vitamin


By Dr. Edward F. Group

Vitamin B-12 is one of the more discussed vitamins and for good reason. It is important for your health overall as it helps several organs and systems in your body function properly, including the brain, the nervous and skeletal systems, DNA replication and energy creation processes.

Let’s take a look at a few reasons why it’s important to make sure you’re getting enough Vitamin B-12.

1. Supports Cardiovascular Health

You’ve probably heard that B-12 is good for cardiovascular health. The way that works is this…

Homocysteine is a protein that naturally forms as a byproduct of your body’s processes. When it builds up, it can corrode and inflame arteries and blood vessels, placing strain on the heart and cardiovascular system. Vitamin B-12 helps converts homocysteine to methionine, a protein the body uses for positive, essential activities.

2. Supports Energy Levels

One of the positive, essential activities that methionine is involved with is cellular energy creation.

3. Promotes Normal DNA and RNA Replication

Your body’s genetic material, DNA and RNA, need vitamin B-12 and folate (Vitamin B9) to replicate correctly. Without it, genetic material can be damaged and lead to mutations. Some speculation has even risen that low B-12 levels are associated with an increased risk of breast cancer.

4. Protects the Nervous System

In addition to converting homocysteine, the methylcobalamin form of B-12 encourages the formation of a protective covering for nerve cells called myelin. This covering protects nerve cells from free radicals and toxins which may be in the blood stream.

5. Protects the Brain, Too

The methylcobalamin form of B12 circulates in the blood stream and can cross the blood-brain barrier to support brain cells just as it protects nerve cells. In one study, 77 patients suffering from Alzheimer’s Disease had significantly lower vitamin B12 levels than individuals in the control group. [1] Other symptoms of low B12 levels include numbness in the hands and feet, memory loss, and disorientation.

6. Encourages a Balanced Mood

Vitamin B-12 plays a role in the creation of serotonin, a chemical that influences brain function and overall mood. In one study researchers examined the effect of B-12 on the brains of diabetic patients who experienced mood imbalances. The diabetic patients with normal levels of B-12 enjoyed better cognitive performance and lower incidence of depression compared to B-12 deficient patients. [2]

7. Essential for Fetal Development

High homocysteine levels in pregnant mothers directly impact fetal growth. Since adequate B-12 contributes to normal homocysteine levels, it can support fetal development. [3]

8. Supports Bone Health

Homocysteine appears to have an impact on skeletal health, too. In recent study 50 patients suffering from osteoporosis were compared to 50 patients with normal bone density levels. Tests showed the osteoporosis patients had high levels of homocysteine and substantially lower levels of vitamin B-12, as well as folate and vitamin B6. [4]

Getting Enough B-12

As essential as B-12 is, it can be tricky to get enough in your diet. Foods that contain B-12 include red meat, organ meats like kidneys and liver, eggs, yogurt, and cheese, and seafood — definitely a problem for vegans or vegetarians. Additionally, many people, especially adults over 50, have trouble absorbing B-12. Commonly prescribed drugs can also cause nutritionally deficiencies, including Vitamin B-12, which have been linked to many health conditions.

One way to fill the gaps between your nutrient intake and nutrient requirements is to supplement. For B-12 supplementation, I like VeganSafe B-12. It contains natural and most bioavailable forms of vitamin B12, methylcobalamin and adenosylcobalamin in an easily absorbed liquid formula.

    I take sublingual B12 daily. My stomach does not absorb B12. I was first diagnosed when I was 45 years old. I am female. Any thoughts on this condition?

  • Another excellent informative article as always.

  • Toni

    The thing about B-12 is we don’t really need to worry about it. The body usually keeps reserve B-12 for 4-5 sometimes more Years.

    Vegans can get B-12 from Nutritional Yeast, Spirulina, Chlorella and other blue-green-algae and other leafy vegetables.

    Surprisingly enough most meat eaters are more deficient then vegans due to their lack of leafy greens they eat. In some cases vegans are still excellent b-12 even after 15+ years.

    So forget 1 article and open 100 articles and find the true answer that suits you best. I have done so and here is a little taste of my result 🙂 Hope it helped

      Nutritional Yeast, Spirulina, Chlorella and other blue-green-algae and other leafy vegetables contain so called “B12-like analogues” which are most likely idle and maybe even counterproductive:

    I suffer from lupus SLE & when I get brain fog ( a feeling that your head is full of cotton wool) I have found that by taking B complex vitamins after a few days it clears. In the past brain fog would last for days followed by raging headaches. I’ve tried to explain this to my rheumatologist but all he seems is to want me to take more prescription pills. Currently I don’t take anything other than juicing fruit & vegetable & eating as healthy as I can. My lupus has calmed down & I now have more good days than bad.

    i inject myself about once a month about 2.5 to 3MLs. I have dyslexia and when I start having mind blocks and can’t tell you the name of things … I know I need a shot. It’s night and day… After my shot… I am most articulate… B12 is awesome. Now that I learned the difference btw the (cyni) and (methl )… I am now injecting once a week about a 10ml… When I bring it up to my dr. They question my reasoning and deny my results… Placebo affect… But I know my body does not lie and I feel the big difference in how my mind works significantly more efficient … I don’t know if my doses are right… I have come up with them on my own via trail and error… When I feel I need it I take…

    Can anyone suggest me B12 tablet’s name?

  • Raed Alsamahji

    I’ve been taking B12 as a supplement for 3 years now, and the results are wonders when it comes to my Increased energy levels and enhanced stable mood levels.

  • Lisa Lowy

    I take the vegan safe B12 that is mentioned here but I am concerned about the glucose in it

  • Matthias Schuster Scharmer

    B12 gets produced by bacteria, which live on the ground – they transform it by cobalt, which is very rare today in the industrial ground and even if it would available, get the B12 washed away by the industrial purge

    a natural, vegan B12 supplementation is – since these type of purge is binding – illegal

    the only 2 ways, to consume B12 – which comes into my mind, is to grow your own food on own ground with enough cobalt in it and the supplementation
