Vitamin B12: Are you Deficient?

By Sonia Reece

The body requires a minimum dosage per day of Vitamin B12 in order to sufficiently prevent anemia and effectively produce red blood cells. In fact, B12 is one of the top 5 nutrients that your body needs to function at its optimum level.

Primarily, B12 is found in animal products such as cheese, eggs and milk. For those of you that are Vegan, you should look for food enriched with B12 or take a high quailty supplement.

What are the signs of being deficient in vitamin B12?

Defiency from B12 can be experienced if you are not eating animal products, like the ones listed above. Other signs of being deficient include, low energy, shores in your mouth, loss of appetite, dizziness, numbness and heart palpitations.

It may take years before signs or symptoms of this deficiency to manifest in your body. Being deficient in vitamin B12 can lead to pernicious anemia and can eventually turn into Alzheimers, loss of memory, confusion and dementia.

Seniors absorb the supplement better in the sublingual form. Malabsorption of the vitamin is another reason for the deficiency. Example, to receive optimal benefits from supplementing with vitamin B12 you would combine with folic acid and vitamin c, which will assist the absorption.

What's a good way to determine the amount needed to prevent becoming deficient?

I had the same question, so after conducting some research and acquiring data from the National Institutes of Health, I came up with the following information.

-.4 mcg- 0-6 months

-.5 mcg- 7-12 months

-.9 mcg- 1-3 years

-1.2mcg- 4-8 years

-1.8mcg- 9-13 years

-2.4mcg- age 14-older

-2.6mcg- pregnant adolescent females

-2.8mcg- lactating females

-25-100mcg- Adults over 50 (unless consistently eating vitamin B12-fortified foods)

Expert opinion may be slightly different, but two ideas were clear: We are designed to absorb low levels of vit B12 at each meal, ranging from .1mcg to 1mcg.

Environmental factors can also affect Vit B deficiency, including regularly consuming chlorinated water. In this case, the body can react to the toxic invasion and the B12 absorption can be low or completely diminished.

Consuming plants and animals that have been treated with pestides and other toxins can also be another source for causing B12 deficiency. - 17269
