Vit B12: Are you getting enough vitamin B12?

By Sonia Reece

Why is it a viable choice to prevent Vit B12 deficiency? Vitamin B12 is one of the top 5 important nutrients in the body. Our body needs vitamin B-12 to produce red blood cells and prevent anemia.

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.

Will you know if you have a deficiency in this vitamin?

Not consuming adequate amounts of the foods listed above and experiencing shortness of breath, dizziness, weakness, nausea, loss of appetite, numbing sensations, low energy, it's quite possible you may have a deficiency.

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.

Sublingual Vit B12 may be the best form of supplementation for seniors to absorb. Another reason for B12 deficiency can also be from malabsorption. For example, taking vitamin C can assist in the absorption, as well as coupling Vit B12 with folic acid, to really get superior benefits.

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 (except if consuming 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 absorption can be affected by environmental factors and respond to the toxic invasion. Consuming chlorinated water regularly, for instance is one example of an environmental factor that can lower or diminish absorption of the vitamin.

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. - 15683
