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.

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.

Symptoms may present themselves after years of b12 deficiency, and usually don't manifest until years later. A deficiency of B12 can produce pernicious anemia, which can lead to Alzheimers, memory loss, confusion and even dementia.

The preferred type of vitamin B12 for seniors is sublingual. Additionally, malaborption is another reason for being deficient. To assist with absorption and optimize your benefits from taking Vit B12, you should also add folic acid and vit C. These vitamins work synergistically with Vit B12.

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

I was pondering the same thing and after researching several reputable sites like National Institute of Health, I was able to come up with this.

-.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 (excluding those eating 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.

Consuming plants and animals that have been treated with pestides and other toxins can also be another source for causing B12 deficiency. - 17944
