That's where we'll cover all the questions you've ever asked about vitamin B12: what is it, how does it work in your body, vitamin B12 benefits, how do you check to see if your B12 levels are low, how do you get it through food, and how much B12 do I need to take a day.

What is Vitamin B12

Vitamin B12 or cobalamin is a naturally water-soluble vitamin that is naturally found in animal food. Vitamin B12 participates in red blood cell formation, nerve function, and DNA. B12 cannot be synthesized by the body independently and thus must acquire it from outside sources such as food or supplements.

Two of the most ubiquitous forms of B12 supplements are cyanocobalamin and methylcobalamin. Both are highly effective, but of course first among them is nature's own methylcobalamin, and it is a top favorite because it is filled with bioavailability.

Health Benefits of Vitamin B12


Red Blood Cell Support

Vitamin B12 is also needed during the production of healthy red blood cells. Since there are not enough amounts in your body, it produces big and inefficient red blood cells, resulting in megaloblastic anemia or vitamin B12 anemia.

Increases Energy Levels

Among the most widely selling products of B12 for energy supplements is that they act as a source. B12 is not a stimulant but rather enhances burning food into energy by boosting your metabolism. It also causes deficiency that results in such weakness or fatigue that it just can't be thought of.

Herbal Remedy and Boosts Mood and Intellectual Functioning

Vitamin B12 helps to promote the production of serotonin, which is needed for mental health. Depressions and dementias have been proven to be caused by a lack of B12, and intellectual acuteness and mental well-being are connected to it.

Function of the Nerves

B12 encourages healthy nerve cells and helps the growth of myelin, bundling tissue around nerves. Numbness, tingling, or irreversible destruction of nerves may be the result with low B12 if not treated.

Skin, Hair, and Nails

Since it is responsible for cell growth, B12 also leads to good skin, healthy hair, and healthy nails. Deficiency of B12 can result in skin diseases such as corner mouth dryness or hyperpigmentation.

Signs and Risk of Vitamin B12 Deficiency

Problems resulting from deficiency of vitamin B12 can be prevented in the future. Years pass by before symptoms of low B12 arise and get worse if left unchecked.

  • Frequent weakness or fatigue
  • Pale yellowish color
  • Numbness or tingling of fingers and toes
  • Trouble with walking or loss of balance
  • Forgetfulness or confusion
  • Mood change or depression
  • Sore red tongue or mouth ulcers
  • Vision loss
If the deficiency of B12 is long-standing, it can lead to permanent damage to nerves, dullness of mind, or life-threatening anemia.

Food Sources of Vitamin B12

Vitamin B12 principally from animal food and therefore found in vegetarians in common.

  • Meat and liver organ
  • Beef, pork, and chicken
  • Salmon, sardines, and tuna fish
  • Dairy foods such as milk, cheese, and yogurt
  • Eggs
  • Nutritional yeast and fortified cereals
  • Fortified plant milk (oat, almond, soy)
In fruit and vegetable disciple vegans, vitamin B12 rich foods are restricted to fortified foods and supplements only. Breakfast cereals or B12-enriched plant milk taken daily will be sufficient to prevent deficiency.


Recommended Daily Dosage

How much B12 should I take daily?
The Recommended Dietary Allowance (RDA) for vitamin B12 is also different depending on health and age:

  • Adults: 2.4 micrograms (mcg) daily
  • Pregnancy: 2.6 mcg
  • Breastfeeding women: 2.8 mcg
  • Older people (>50 years): Typically recommended to take B12 from fortified foods or supplements since absorption is minimal
As it is water-soluble, as excess is typically eliminated through urine, it's comparatively safe even if in excess.

Can Too Much Vitamin B12 Be Had?

Compared to fat-soluble vitamins, B12 is toxic-free and non-toxic even with increased B12 dosage per day. B12 supplements easily get absorbed by all individuals, and no overdose levels are seen because your body expels what it does not require.

Suppression, nonetheless, particularly with vitamin B12 injection, must be carried out under medical supervision. Flushing briefly over the face, headache, or nausea in some patients occur after injection. Infrequently, high doses interfere with other drugs (e.g., proton pump inhibitors, metformin) or cause acneiform-type rashes.

B12 Absorption and Special Considerations

B12 isn't always absorbed. It needs intrinsic factor, which is protein the stomach releases to allow B12 to attach on so the body can absorb it. Individuals with gastrointestinal illness such as pernicious anemia, celiac disease, or Crohn's disease can't.

The reduction in the emission of gastric acid is associated with old age, the consumption of which increases B12 absorption from diet. Therefore, B12 is usually supplemented or intramuscularly applied to the older individuals to stimulate its highest effect.

Some drugs, such as metformin (it's for type 2 diabetes patients) and antacids, affect the absorption of vitamin B12. So they need to be watched out for intervals.

Vitamin B12 for Vegetarians and Vegans

However, vitamin B12 sources for vegans or vitamin B12 for vegetarians are very low. Because plant food will never have a steady supply of B12, vegetarians will get at least some from eggs and milk and leave the vegans with absolutely none.
To stay high in B12 without eating meat:

  • Fortify foods (plant milk, cereal, nutritional yeast)
  • Taking daily B12 supplements (including cyanocobalamin or methylcobalamin)
  • Having your blood checked regularly to check your levels of B12
However, methylcobalamin vs cyanocobalamin is equal, although it may last longer and be better absorbed when taken orally. If you just cannot decide between the two, ask your doctor for further advice.
