Vitamin B-12 is an essential water-soluble vitamin that is commonly found in a variety of foods such as fish, shellfish, meat, eggs, and dairy products. Important in DNA synthesis, vitamin B-12 is frequently used in combination with other B vitamins in what is known as a vitamin B-complex formulation. Vitamin B-12 is bound to the protein in food, and released by stomach acids during digestion. Once released, B-12 combines with a substance called intrinsic factor (IF) before it is absorbed into the bloodstream.
The human body stores several years' worth of vitamin B-12 in the liver, so low levels in the body are rare. Decreases in vitamin B-12 levels are more common in the elderly, HIV-infected persons, and vegetarians. Vitamin B-12 deficiency is often defined by low levels of within the body stores of this vitamin, which can result in anemia – a lower-than-normal number of red blood cells wherein some of the symptoms include fever, excessive sweating, and soreness or weakness in the arms and legs. The inability to absorb vitamin B-12 from the intestinal tract can lead to various types of anemia, the most prominent of which is a type of megaloblastic anemia called pernicious anemia. However, this form of anemia is quickly remedied through vitamin B-12 supplementation.
Vitamin B-12 has a fascinating history, which rounds out over a decade of vitamin research as the last vitamin to be discovered. An essential daily nutrient, vitamin B-12 is needed to maintain healthy red blood cells, healthy nerve cells, and to make DNA. However, it was discovered as a cure to a condition known as pernicious anemia, which is directly related to a vitamin B-12 deficiency.
Pernicious anemia is a blood disorder in which red blood cells fail to develop normally, resulting in the steady decline of red blood corpuscles that was fatal until the 1920s. The disease was first described completely in 1849 by English physician Thomas Addison (1793-1860), who noted that the typical symptoms included increasing weakness and pallor, accompanied by obesity or weight gain rather than weight loss.
Numerous scientists played roles in helping to discover and isolate the causes and cure for anemia:
Pernicious anemia is a decrease in red blood cells that occurs when your intestines cannot properly absorb vitamin B-12, and presents a host of complications and symptoms. However, studies have shown that a deficiency of vitamin B-12 can also lead to abnormal mental symptoms. These symptoms may include ataxia (shaky movements and unsteady gait), muscle weakness, spasticity (stiff or rigid muscles), incontinence (lack of bladder and/or bowel control), hypotension (low blood pressure), vision problems, dementia, psychoses (abnormal condition of the mind), and mood disturbances. Giving vitamin B-12 by mouth, by injection, or by nasal inhalation is effective for preventing and treating dietary vitamin B-12 deficiency.
There exists a long list of other conditions, disorders, and complications related to vitamin B-12 deficiency, and on which the research remains unclear/inconclusive, but has shown some improvement during vitamin B-12 supplementation including:
Alzheimer's disease, Angioplasty (opening narrowed or blocked arteries), Breast cancer, Canker sores, Cardiovascular disease hyperhomocysteinemia, Cervical cancer, Claudication (leg pain from clogged arteries), Depression, Diabetic neuropathy (nerve damage), Diagnostic procedure, Facial spasm, Fatigue, Fractures (prevention), High cholesterol, Imerslund-Grasbeck disease, Joint pain (elbow), Mental performance, Poisoning (cyanide), Shaky-leg syndrome, Sickle cell disease, Sleep disorders (circadian rhythm)
Vitamin B-12 is necessary to produce an adequate amount of healthy red blood cells in the bone marrow, is available only in animal foods (meat and dairy products) or yeast extracts (such as brewer’s yeast). Vitamin B-12 is a water-soluble vitamin, which means it easily dissolves in water and is paradoxically stored in the liver (making it a good source). It is eliminated from the body through the urine, typically between 24 and 72 hours after consumption, depending on how active a person is and the amount of fluids they take in. Due to the rapid rate with which the body processes Vitamin B-12 frequent supplementation is needed to address deficiencies and gain maximum benefits.
The stomach acids that aid in the natural breakdown of food also breakdown vitamin B-12 pill supplements, the body will only absorb a small amount of the pill form. In addition, as you get older your body’s ability to absorb B-12 through digestion continually decreases. In fact, many adults are completely unable to absorb B-12. Injections provide a direct and concentrated method of supplying your body with the vitamin B-12, and are of particular value to older populations when normal absorption rates decrease, even in the absence of pernicious anemia. The conventional way of fixing a vitamin B-12 deficiency has been through intramuscular injections, which experiments also reveal to be useful healers of neurological disorders, such as progressive memory loss and lethargy.
Research findings show ample evidence to reveal that injections of 1 to 2 milligrams per day can quickly correct deficiencies. It is not apparent whether smaller amounts, such as the 25 micrograms or so found in multivitamins, are sufficient to cure deficiencies. Such a claim is substantiated by the fact that although oral supplementation with vitamin B-12 is safe, efficient, and inexpensive most multi-vitamin pills contain 100-200 micrograms of the cyanocobalamin or methylcobalamin forms of B-12. Furthermore, many multivitamins cannot be chewed, which is important for their breakdown and thorough absorption.
Routine B-12 injections at a dosage of 1 milligram per month also helps to lower homocysteine levels in the blood, thereby reducing the probability of heart diseases and strokes. A vitamin B-12 injection acts as a stimulant for energizing the body, through cobalamin, which transmits its “anti-stress” elements to the human body. For example, the recommended effective cure for chronic fatigue syndrome (CFS) is 6 to 7 milligram dose of vitamin B-12 intramuscular injection per week for 3 weeks.
Renowned doctors have conducted important studies with Chronic Fatigue Syndrome (CFS) patients who’ve received high doses of B-12 injections. The B-12 shots dramatically increased energy in 80% of the participants, and improved sleep quality. Now doctors everywhere are administering B-12 shots to provide patients with renewed energy and vitality. However, as seen here vitamin B-12 has numerous applications, and most people of seek the injections do so for these key benefits:
Boosts energy and overall metabolic rate, Assists in the burning of stored body fat, Detoxifies the body, Increases red blood cell production, Maintains a healthy liver, Helps regulate sleep, mood, appetite and energy, Works synergistically with other nutrients to improve health
B-12 injections can not legally be sold online. Real B-12 Injections can only be obtained with a prescription from a licensed healthcare provider. If you are looking for a fast and effective weight loss plan B-12 may be just what you need.
