Vitamin B12 Supplements

What is Vitamin B12 and what is its function?

Vitamin B-12 (cobalamin) is an essential nutrient required by the body that plays a critical role in various vital bodily functions such as making DNA, helps to keep nerve cells and red blood cells healthy etc. Vitamin B12 is also effective in preventing the risk of megaloblastic anemia that makes people constantly feel weak and tired.

Vitamin B-12 is considered as an effective treatment for many diseases and conditions such as memory loss, fatigue, Alzheimer’s disease, heart disease, high cholesterol, and sickle cell disease.

What are Vitamin B12 Supplements?

Vitamin B-12 supplements are essential for fulfilling the requirement of B12 in people with Vitamin B12 deficiency. Generally, the low levels of vitamin B-12 are more likely to occur in people over age 60, which can be treated with Vitamin B12 Supplements.

Since the Vitamin B12 is made in the gut, eating enough healthy foods and proper digestion ensures that the body is getting enough Vitamin B12. Taking Vitamin B Complex further helps to deal with the daily Vitamin B12 requirement.

However, we may need to take extra Vitamin B12 Supplement if we see frequent B12 deficiency symptoms such as low energy, depression, anxiety.

Vitamin B12 supplement requirement in various age groups

The amount of vitamin B12 supplement needed by an individual depends largely on the age and certain other factors. It is important to note here that even if we are eating plenty of healthy food and animal products but if our digestive system is off, we are going to have trouble getting enough B12.

Vegetarians are the most suspect to having a B12 deficiency and hence they should supplement their diet with B12.

On an average, the Vitamin B12 supplement requirement by the individuals of various age groups are listed below-

  • From birth to 6 months -0.4 micrograms
  • Infants 7–12 months – 0.5 micrograms
  • Children in age group 1–3 years -0.9 micrograms
  • Children in age-group  4–8 years- 1.2 micrograms
  • Children in age-group 9–13 years- 1.8 micrograms
  • Teens 14–18 years- 2.4 micrograms
  • Adults -2.4 micrograms
  • Pregnant women- 2.6 micrograms
  • Breastfeeding women- 2.8 micrograms

The process of absorption of Vitamin B12 from food by the body occurs in two simple steps. In the first step, the hydrochloric acid in the stomach separates vitamin B12 from the protein to which vitamin B12 is attached to food.

In the subsequent step, vitamin B12 combines with a protein made by the stomach called intrinsic factor and is absorbed by the body. In people suffering from pernicious anemia, the body cannot make intrinsic factor which makes it difficult to absorb vitamin B12 from all foods and dietary supplements.

Best Vitamin B12 Supplement

One of the best Vitamin B12 supplement for absorption is sublingual B12 or taking injections.

Methylcobalamin: It is the most common form of Vitamin B12 supplement. There are several studies that show that it is better absorbed since it overrides a few problems that can occur in the B12 absorption cycle. Furthermore, it also provides methyl groups to the body, which are important for overall health and mood.

Vitamin B12 dietary supplements

Vitamin B12 is normally found in almost all multivitamins. Vitamin B12 Supplement is also available in sublingual forms, which gets dissolved under the tongue. However, there is no proof or evidence available that the sublingual forms are better absorbed than the Vitamin B12 pills that are swallowed. Below are the various Vitamin B12 supplements available in dietary form-
