Benefits Of Vitamin B12

Vitamin B12  
Are you feeling tired, worn out, and don’t have much energy? Then there is a possibility you may have a vitamin B12 deficiency.
What is it? & What does it do?

Vitamin B12, a member of the B-vitamin family, is a term used collectively to represent a group of cobalt-containing compounds known as corrinoids. The principal cobalamins are cyanocobalamin, hydroxocobalamin, and the two coenzyme forms of vitamin B12, methylcobalamin, and 5-deoxyadenosylcobalamin (adenosylcobalamin). However, the term vitamin B12 is usually used to refer to only one of these forms, cyanocobalamin, which is used to fortify foods and nutritional supplements. Vitamin B12 is a water-soluble vitamin required for normal cell activity, DNA replication, and the synthesis of the mood-influencing substance SAMe. Vitamin B12, also known as cobalamin, works with folic acid to produce healthy red blood cells. Vitamin B12 also keeps your central nervous system healthy.
Benefits
This very important nutrient helps support higher energy levels, emotional stability, mental clarity and more. One of the primary vitamin B12 benefits is its crucial role in energy metabolism. It’s been unofficially coined the “energy vitamin.” Although it won’t directly cause weight loss, because B12 is known to increase your energy and metabolism, many claim it may assist with the process.
Another of the B12 benefits is that it protects myelin which is a fatty material that covers your nerves and enables them to transmit electrical impulses/messages between the nerve cells throughout the body. Depressed patients often have low serotonin so one of the benefits of vitamin b12 is their role in preventing depression which is another of the reasons it is often called an energy vitamin. They also support your growth and appetite. People sometimes associate this vitamin with weight loss because since it increase your energy and metabolism your body will naturally  increase its daily energy consumption.

Vitamin B12 has health benefits for young and old alike, and everyone in between. It combats asthma in children, has shown promise against HIV in adults, and has helped the elderly who find their minds aren't as sharp as they used to be.

Older adults who notice a decline in mental function, even the emergence of Alzheimer's disease, need to get on the B12 bandwagon. Experts have found that when mental symptoms are treated with vitamin B12 within six months of onset, many of the symptoms disappear or mental clarity improves.
Vitamin B12 may also help alleviate depression in the elderly by working with a compound that helps to make serotonin, the neurotransmitter responsible for a calm feeling of well being.

B12 also plays a role in melatonin production. Melatonin is the hormone responsible for letting you get a good night's sleep. As we age, the body is less efficient at making this hormone. B12 supplementation has helped some older adults sleep better.

On the opposite end of the life spectrum, children who have asthma may benefit from vitamin B12 as well. Weekly injections of 1,000 mcg or daily oral supplements of 1 to 3 mcg improved their condition and resulted in less shortness of breath.

AIDS patients typically have low levels of this vitamin. This can be used as an indicator that overall nutritional status is low and that attention needs to be given to intake of all nutrients. In the laboratory, vitamin B12, in any form, reduces replication of HIV. This is a hopeful treatment yet to be tested in humans.

Several studies show that B12 dramatically increases ***** counts in men whose counts are low. The vitamin also jump-starts *****'s action, increasing motility rates.

People with tinnitus, that constant ringing in the ears, are often deficient in vitamin B12. Supplementation diminishes the irritating ringing for some people.

Adequate quantities of vitamin B12 help in treating diseases and disorders such as, diabetes, insomnia, allergies, osteoporosis, asthma, etc. Vitamin b12 is the best vitamin for almost every disease

Who Needs It?
Normally the body stores an ample reserve of B12 in the liver, however babies and young children sometimes develop deficiencies because their bodies haven’t had time to stockpile the vitamin yet. Senior citizens and those that have had certain types of digestive tract surgery are at above-average risk. Those whom do not consume meat and dairy almost certainly need to buy supplements, because this substance is not found in plant-based foods. And the bodies of women who are pregnant require an increased amount of vitamin B12.
Even if you do get enough through your diet, there is a possibility your body isn’t metabolizing it correctly. This is a common reason many people need to supplement. In fact, 10 to 30% of older adults are known to suffer from atrophic gastritis which decreases the absorption.

Who Needs a Supplement to Get Vitamin B12 Benefits?
Anyone who cannot get enough vitamin B12 through their food needs a supplement. That includes anyone who has a low serum B12 level and/or anyone who has symptoms of vitamin B12 deficiency, even if blood tests do not show low levels of vitamin B12.
A supplement may help you get vitamin B12 benefits if you experience any of the following symptoms:
  1. Numbness and tingling in your hands or feet
  2. Fatigue
  3. Muscle weakness
  4. Poor appetite
  5. Pallor
  6. Shortness of breath
  7. Sore mouth and tongue
  8. Confusion, memory problems or any unexplained change in mental status
 
What Happens without it?
 
Vitamin B12 deficiency may result negative in hematological, neurological, and gastrointestinal conditions. Gastrointestinal effects of B12 deficiency may include diarrhea, constipation, abdominal pain, excessive flatulence, and a burning sensation on the tongue. B12 deficiency can cause a type of anemia marked by fewer but larger red blood cells that's called pernicious anemia. It can also cause walking and balance problems, sore tongue, weakness, confusion and, in advanced cases, dementia. Prolonged B12 deficiency can lead to nerve degeneration and irreversible neurological damage. People with vitamin B12 deficiency show irregular destruction of the myelin sheaths, which eventually causes paralysis and death.Vitamin B12 levels decrease with age and various measures of cognitive impairment are associated with reduced B12 status.
 
Even in the absence of anemia, the neurological effects of vitamin b12 deficiency can still occur. This is especially true for the elderly. In theses cases, vitamin B12 deficiency can affect the peripheral nerves, and in later stages, even the spinal cord itself. Signs of neurological conditions caused by B12 deficiency include tingling and numbness in the extremities, loss of sensation, spacticity, Babinski's responses, visual impairment, bowel control issues, insomnia, impotence, irritability, depression, memory loss, and dementia.

Additional conditions that have been associated with vitamin B12 deficiency include anorexia, weight loss, age-related hearing loss, Alzheimer's disease, and pernicious anemia.
 
Studies have shown that a deficiency of vitamin B12 can lead to abnormal neurologic and psychiatric symptoms. These symptoms may include: ataxia (shaky movements and unsteady gait), muscle weakness, spasticity, incontinence, hypotension, vision problems, dementia, psychoses, and mood disturbances. Researchers report that these symptoms may occur when vitamin B12 levels are just slightly lower than normal and are considerably above the levels normally associated with anemia.

Breast cancer
Researchers at Johns Hopkins University report that women with breast cancer tend to have lower vitamin B12 levels in their blood serum than do women without breast cancer. In a subsequent review of these findings, it was hypothesized that vitamin B12 deficiency may lead to breast cancer because it could result in less folate being available to ensure proper DNA replication and repair. Higher dietary folate intake is associated with a reduced risk of breast cancer. The risk may be further reduced in women who also consume high amounts of dietary vitamin B12 in combination with dietary pyridoxine (vitamin B6) and methionine. However, there is no evidence that dietary vitamin B12 alone reduces the risk of breast cancer.
