Vitamin B12: Are you Deficient?

By Sonia Reece

Vitamin B12 is one of the top 5 important supplements in a balanced diet. Your system requires B12 in order to prevent anemia and produce red blood cells.

This vitamin is found almost exclusively in animal products, including milk, eggs and cheese. Those on a Vegan diet or lifestyle can get vitamin B-12 from enriched cereals, fortified soy products or by taking a supplement that contains this vitamin.

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.

Pernicious anemia can be a potential outcome from chronic vitamin B12 deficiency, will symptoms not presenting themselves for many years. Chronic anemia can also develop into loss of memory, Alzheimers disease, disorientation 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.

So, now you might be wondering how much is ENOUGH? What is the proper dosage to prevent Vit B12 deficiency?

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.

Vitamin B12 deficiency also depends on environmental factors. For example, if we consume chlorinated water on a daily basis, B12 absorption would be low or diminished based on the toxic invasion on the body.

Also, consider the possibilites of pesticides and toxins from the plants and animals we are consuming and how that may to affect the absorption of B12. - 15438
