There is so much information out there over the internet regarding claims about b12. Here is a synopsis of major truths regarding b12 and its benefits.
What is B12?
Vitamin Health
Vitamin B12 is a water soluble vitamin (as opposed to fat soluble vitamins such as vitamins A, D, E, and K). It is necessary for maintaining the basic unit of our nervous system called a neuron or nerve cell. It also helps our bone marrow to make blood. Therefore, it is also necessary to maintain the health of red blood cells to prevent anemia. B12 also helps the body to make and maintain our genes or DNA. You may sometimes here b12 referred to as cobalamin because of the cobalt content of this vitamin. Cyanocobalamin is a man-made form of b12. Your body can convert b12 to two usable forms (or coenzymes): adenosylcobalamin and methylcobalamin.
Where is B12 Found naturally?
It is found mostly in animal products such as seafood, meat (especially beef), milk and eggs.
Consequences of Vitamin B12 Deficiency
There are numerous consequences of b12 deficiency. Some symptoms are more exaggerated with with increasing severity of deficiency. Some of the major signs and symptoms are: Anemia (low red blood cell counts / low hemoglobin). You may hear the term megaloblastic anemia which means your red blood cells are large and pale (the lack of hemoglobin which makes our blood red). Other signs and symptoms include fatigue (tired), a depressed mood, numbness or tingling of feet or hands, decreased or poor memory, a decreased ability to reason, and a slow gastrointestinal track that leads to bloating and constipation.
Who is at risk for Vitamin B12 Deficiency?
Individuals at risk include those who eat very little or no seafood, meat, eggs or milk. Vegetarians, especially vegans are at probably at the greatest risk and should take a b12 supplement unless advised otherwise by a physician.
What is the the body's usual requirement for b12?
According to the NIH, office of dietary supplements, an adult needs about 2.5 micrograms per day. If you are pregnant or breast feeding, youw will need closer to 3 micrograms.
What is too much B12?
It has a very low potential for toxicity. Since b12 is a water soluble vitamin, the excess should be cleared by the kidneys via the urine. However, with significant kidney disease this can be a problem. If you are folate deficient, high consumption of b12 can drop your folate levle and and anemia may follow. There are some unusual circumstances where medical advice is a must: if you are allergic to cobalt or have a condition known as Leber's disease.
Sublingual B12 vs Injection
Sublingual is usually less expensive and obviously not painful. Sublingual rapidly gets the vitamin into the blood stream. There is no need to go to a physician's office for regular doses as well. However, do follow up with your physician regarding the condition that lead to a b12 deficiency or to recheck a b12 level.
