B12 Deficiency: Don’t Ignore the Symptoms

Tuesday, May 10th, 2011



Vitamin B12 deficiency can start with a few symptoms like tiredness and slight tingling or numbness in hands and feet; ignore the symptoms and low B12 levels could escalate into severe nerve damage, disease or death.


What are the symptoms of vitamin B12 deficiency?

Below is a list of some of the most common side effects which may arise from insufficient stores of vitamin B12.

(Please note that the severity of the symptoms may vary according to the stage of B12 deficiency.)

  • Fatigue
  • Depression
  • Aggressive behavior
  • Hallucinations
  • Sleep problems
  • Frailness
  • Imbalance, difficulty walking with coordination
  • Numbness or tingling in the hands and/or feet
  • Altered taste perception

B12 and your body

Vitamin B12 is a water-soluble nutrient. Therefore, your body is only able to store it for a short time. Vitamin B12 has many important functions in your body.

  • Vitamin B12 is essential for producing plenty of healthy red blood cells and for synthesizing DNA. A lack of B12 severely reduces your body’s ability to make sufficient red blood cells for carrying oxygen throughout your body.
  • Pernicious anemia is a life-threatening condition that is often the cause of vitamin B12 deficiency.
  • Your nervous system is dependent on vitamin B12, which enhances communication between the brain and your many nerve sensors, such as those in your fingertips, feet and mouth. This explains why sufferers of B12 deficiency notice a sensation similar to wearing gloves throughout the day; others report that their food tastes unusual, another clue that the body’s neurons are not operating correctly.
  • A deficiency of vitamin B12 compromises your nervous system and could result in permanent neurological damage.
  • Researchers have found a direct link between vitamin B12 deficiency and brain atrophy among the elderly. In one study which appeared in the Journal of Nutrition, senior citizens who had the highest levels of B12 experienced healthier cognitive functioning skills.

  • Vitamin B12 helps your body monitor already healthy homocysteine levels, a factor in heart health.

What diseases are associated with B12 deficiency?

There are many illnesses which occur when B12 levels are low; some conditions may be caused by vitamin B12 deficiency, while others are closely correlated. Below are some common illnesses associated with B12 deficiency, including many which most people don’t realize are affected by vitamin B12 levels.

  • Alzheimer’s disease, brain deterioration, cognitive decline, memory loss and other forms of dementia
  • Neurological diseases such as Multiple sclerosis (MS)
  • Cardiovascular disease, caused by high homocysteine levels
  • Mental illness, including depression, anxiety, bipolar disorder and psychosis
  • Autism spectrum disorder
  • Autoimmune diseases, such as AIDS and pernicious anemia
  • Infertility

Eating Your Way Out of Depression with B-12

B12 deficiency is often misdiagnosed

According to a Tufts University study, 40 percent of people between the ages of 26 and 83 have low to medium-low B12 levels, indicating a deficiency severe enough to cause neurological disorder symptoms, while 9 percent are depleted enough to the point of irreversible neurological damage and life-threatening symptoms. Approximately 16 percent are close to becoming vitamin B12 deficient.

Why is vitamin B12 deficiency overlooked?

Only a blood test can properly determine if somebody is suffering from B12 deficiency, and most physicians don’t include a B12 screening with yearly check-ups. Also, many of the symptoms of vitamin B12 deficiency are similar to common health disorders, such as diabetes, chronic depression and fatigue.

How can you get enough B12?

Vitamin B12 is found in many high protein foods. Excellent sources of B12 are:

  • Lean beef cuts, such as chuck and sirloin
  • Poultry
  • Fish, particularly salmon, tuna and halibut
  • Shellfish, including crab meat, mussels, clams and oysters
  • Dairy products, such as swiss cheese, yogurt, milk and cottage cheese
  • Eggs

Vegans are at a high risk for developing vitamin B12 deficiency, as their diet specifically excludes food items which provide vitamin B12. Other people who are at risk of getting B12 deficiency are patients of weight loss surgery, diabetics on metformin, individuals with gastrointestinal disease, people who lack intrinsic factor and anybody taking prescription heartburn medication.

The only way to prevent becoming deficient in vitamin B12 is by constantly replenishing your body with B12-rich nutrients.

Alternatively, patients diagnosed with vitamin B12 deficiency are encouraged to take vitamin B12 supplements, such as sublingual B12 tablets, B12 shots, or over-the-counter (OTC) vitamin B12.

Eating Your Way Out of Depression with B-12

Thursday, March 10th, 2011

We’ve all heard of overeaters binging themselves into a state of depression- a vicious circle which is difficult to get out of. But eating for happiness?

Vitamin B-12 deficiency is linked with depression

Vitamin B12 is essential for many aspects of brain development, such as myelination (the production of a protective layer around the brain) and the distributing of neurotransmitters to and from the brain. So it comes as no surprise that the Mayo Clinic suggests eating foods rich in vitamin B-12 as a means of preventing the onset of clinical depression.

“Eat to live, don’t live to eat.”

That’s a great motto if you happen to be an android. The fact is, eating is a sensual experience which we were meant to enjoy. (Why else would we have taste buds?) The key to good nutrition is finding foods you love that will love you right back.

Male depression is on the rise. Is it the recession or “Manpression?

Here are some yummy appetizers and entrées which are naturally high in vitamin B-12:

  • Fish tacos- Made popular by Rubio’s, the fish tacos is a tasty fusion of Cal-Mex and seafood cuisine.  Take a soft flour tortilla, add some fiery mango salsa, a dab of sour cream and a grilled fish fillet (hint: salmon is high in B-12).  It’s a wrap!
  • Are you a Sushi lover? Then you’re going to love this- sushi and sashimi recipes typically include such high-in-B12 ingredients as roe (fish eggs), octopus, crab, shrimp, and mackerel. Pass the soy sauce!
  • New England clam chowder- just the name elicits images of salty sea breezes, sailboats and clam bakes. Don’t have any recipes handy? Here is a list of variations on this classic soup recipe.
  • Lean cuts of lamb are high in vitamin B-12 and a popular staple of many Middle Eastern cuisines. Here is a flavorful Lamb Moussaka recipe, as featured in epicurious.
  • Tuna casserole is one of America’s fave comfort foods and it’s simple to make- combine canned tuna, cooked broad noodles, and a can of concentrated mushroom soup. Top it with some fried onions and pop it in the oven for 30 minutes. Tuna is high in B-12 and omega-3 fatty acids.
  • Hamburgers barbecued with low-fat ground beef chuck are a great source of vitamin B-12. Serve it up on whole-grain buns with a side of oven roasted root veggies for a healthy upgrade from the typical artery-clogging burgers ‘n fries.




Vitamin B12 Toxicity

Tuesday, February 6th, 2007

Vitamin B12 Deficiency

Vitamin B12 is the only vitamin that is not known to have toxic effects even when taken in large doses. Patients with anemia have been given 1,000 mcg monthly injections to treat vitamin B12 deficiency without any side effects. However, for healthy individuals, large doses of vitamin B12 are not recommended. Healthy adults get enough of this vitamin from a balanced diet. Healthy adults are recommended to take one multivitamin daily that contains vitamin B12. Those at risk for vitamin B12 deficiency include the elderly and vegetarians. The elderly are at risk for atrophic gastritis, and vegetarians often need supplementation because vitamin B12 is found only in foods from animal products. A strict vegetarian diet which prohibits consumption of animal products can result in vitamin B12 deficiency.

Additional Supplementation

Patients with anemia cannot absorb vitamin B12 from food or oral supplements. Therefore, vitamin B12 injections are usually required to correct anemia and to prevent irreversible neurological damage. Patients who have had surgical removal of the stomach lack intrinsic factor which is produced in the stomach, so they cannot absorb vitamin B12 from food or supplements. Patients with resection of the small bowel may not be able to absorb vitamin B12 from food and supplements. Patients with a condition of food allergy to gluten that leads to atrophy of the small bowel lining may also not be able to absorb vitamin B12 from food and supplements. Also, some medications affect the absorption of vitamin B12 in the body. For example, medication used to control blood glucose levels with type II diabetes, treatment used to lower blood cholesterol levels, and also some medications used to control unexplained diarrhea have been known to inhibit the absorption of vitamin B12 from food.

Effects Of Vitamin B12

The Importance Of Vitamin B12

The amount of vitamin B12 required by the human body is relatively low, but the function it performs can not be ignored. The two most significant functions of vitamin B12 are cell division and the formation of red blood cells. The absorption of vitamin B12 within the body is a complicated process because it involves the release of some intrinsic stomach liquids, including stomach acids. Vitamin B12 is found naturally in many plant and animal sources. However, neither plants nor animals can directly synthesize this vitamin. Certain bacterium is capable of producing vitamin B12, and later adds them to plants. Animals become a source of vitamin B12 after they eat those plants.

Side Effects Of Vitamin B12

Scientific studies have found that vitamin B12 has very low potential for toxicity. This means that even if the vitamin is taken in excessive amounts it can not cause adverse effects. Even in high doses, oral vitamin B12 is well tolerated by the body. Very rarely are there reports of hypersensitive reactions such as urticaria, rash and pruritis, and these occur only in patients receiving parenteral vitamin B12. Those patients who experience hypersensitive reactions from parenteral supplementation may also have the same reaction from oral supplementation. It is advised that patients who are allergic to cobalamin or cobalt should not take vitamin B12.

Vitamin B12 Injection Benefits

About Vitamin B12 Injections

Vitamin B12 injections are only administered when there is no other way of supplementation. Injections are mostly used in cases of diseases caused by vitamin B12 deficiency. Injections are usually administered to people who have a medical problem known as pernicious anemia, a condition in which the patient is not capable of absorbing vitamin B12 via the intestine. Injections are also administered to those who suffer from a diseased intestine or have a large part of their stomach or intestines removed. Vitamin B12 injections are only given by or under the supervision of a health care professional. In the United States, injections of vitamin B12 are generally available in two types, cyanocobalamin and hydroxocobalamin.

Advantages of Vitamin B12 Injections

Vitamin B12 injections have been used for a long time, especially by many politicians and famous personalities from the entertainment industry. There are several reasons why. The injection contains 500 times more vitamin B12 than the recommended daily dosage.  When injected, vitamin B12 is easily absorbed by the body and then utilized in the formation of red blood cells as well as aiding in the maintenance of a healthy nervous and cardiovascular system.  The three major health benefits of vitamin B12 injections are an increase in energy, sleeping better, and a feeling of alertness.  However, people often complain of bruises and soreness in the area where the vitamin B12 was injected.
