The metal cobalt is incorporated into vitamin B-12, which is the basis of the alternative name of this vitamin, cobalamin. A vitamin B-12 deficiency is more common in the elderly, affecting between 10 and 15 percent of those over 60 years of age. Some diseases are the cause of the deficiency, including pernicious anemia, and conditions that reduce the amount of vitamin B-12 absorbed by the gastrointestinal tract.

Who Is Prescribed Vitamin B-12 Injections

Vitamin B-12 in the form of cyanocobalamin is prescribed to treat severe vitamin B-12 deficiencies. One manufacturer of injectable vitamin B-12 is American Regent Inc., and they have published prescribing information for this medication. According to this manufacturer, vitamin B-12 injections are generally prescribed for people in whom the deficiency is caused by insufficient absorption of vitamin B-12 through the gastrointestinal tract. Cyanocobalamin is used to treat pernicious anemia; illness, dysfunction and/or surgery of the gastrointestinal tract that prevents normal vitamin B-12 absorption; pancreas or bowel cancer; deficiency in folic acid; and/or a tapeworm infection. In addition, some people who eat a strict vegetarian diet do not get enough vitamin B-12, and may need injections or high dose oral vitamin B-12 to correct a deficiency.

Characteristics

Vitamin B-12 injections are given intramuscularly or subcutaneously, meaning that vitamin B-12 is injected directly into the muscle or underneath the skin, respectively. The injectable vitamin B-12 is in the form of cyanocobalamin, which is the principle form of this vitamin used in supplements.

Common Vitamin B-12 Doses

For those with pernicious anemia, monthly injected doses of vitamin B-12 should be taken for life. At the start of treatment, 100 mcg are injected each day for six or seven days. Blood tests reveal if the doses of vitamin B-12 are raising the level of this vitamin in the blood; if improvement is seen, then the doctor may change the dose to every other day for an additional seven days, followed by every three or four days for between two and three weeks. When levels of vitamin B-12 become normal in the blood, monthly injections at 100 mcg should be repeated for life. Make sure to consult a medical professional before beginning a regimen of vitamin B-12 injections.

Side Effects and Safety

Doses up to 1,000 mcg per month of injected vitamin B-12 have no toxic effects in those who have pernicious anemia but are otherwise healthy. The most common side effects of vitamin B-12 injection are diarrhea and swelling. Other symptoms that are less common include muscle pain, weakness and cramps; intense thirst and frequent urination; coughing, wheezing and shortness of breath; and fast heart rate and dizziness. If you are allergic to any of the components of the injectable vitamin, you may experience swelling, redness, hives, rash, itching and/or difficulty breathing or swallowing.

My girl takes b-12 pills. I've never tried the injects would like to though

Thanks for posting that Beanlicker.
I found it really interesting and actually was surprised.
One would think that with it being water soluable it would leave the system rather fast.
But apparently you can build it up in the bloos level and then have less frequent injections.
Many endurance athletes use it.

i take mio energy.. it contains all b vitamins and no sugar... i use it as a pre workout drink

Wouldn't you have to be deficient in it to get any real benefit? Multiple doctors as well as dieticians have told me this. Naturalists (chiro's) too...

What is the maximum weekly mg of B12 any recommendations?

ive only tried caps n orals of b-12 didnt notice anything great, however friends of mine done injections and swear by energy, mood elevation, focus.

Methylcobalamin Injection -VS- Cyanocobalamin Injection

Methylcobalamin Injection

This B12 Injection is Methylcobalamin. Injectable B12 Methylcobalamin is the best and purest source of Vitamin B12.
Methylcobalamin B12 is better absorbed than Cyanocobalamin. Vitamin B12 injections is are important for:

• absorption of foods
• proper digestion
• DNA
• healthy nerve cells
• red blood cells

Vitamin B12, known as cobalamin, is commonly available in two forms: Methylcobalamin and Cyanocobalamin. Proper absorption of vitamin B12 requires normal function of the digestive system, specifically the stomach, pancreas, and small intestine. B12 is typically available as an oral B12 supplement or as a vitamin B12 injection. Because of poor absorption into the body, Vitamin B12 injections are by far the most effective method for supplementation. Whether in the form of a B12 tablet, capsule or as Vitamin B12 shot, it has the most complex chemical structure of all the B12 shots. Methylcobalamin is the form of vitamin B12 used in the human body, whereas Cyanocobalamin is the most prevalent form used as a nutritional supplement. In order for Cyanocobalamin to be utilized by the body it must first be converted to Methylcobalamin and 5-deoxyadenosy. Because Cyanocobalamin requires the secondary step of being converted to Methylcobalamin in the body, it is the least efficient means to cure the body of a Vitamin B deficiency.
Methylcobalamin is the only form of b12 injection that is naturally supported by the human body without having to go through an unnecessary chemical breakdown.
According to studies, Vitamin B12 deficiency affects at least 10% of individuals over age 60. According to the Linus Pauling Institute the most common forms for Vitamin B12 deficiency are autoimmune conditions and food-bound vitamin B12 malabsorption. Both causes, though separate, become more prevalent with age.

Methylcobalamin 1000mcg/ml compounded Vitamin B12 injection is available in 10ml and 30ml vials (10-30 doses for injections).
Dosing:
1ml Intramuscular 1-2 times per week.

Cyanocobalamin Injection

The least expensive and popular B12 Injection Kit. This B12 Injection is Cyanocobalamin. This form of vitamin b12 has been used for many years for many conditions. It is easily converted systemically to Methylcobalamin for use by the body.
Vitamin B12 Injections is the name for a class of chemicals known as cobalamins that are commonly available in two major forms: Methylcobalamin and Cyanocobalamin. The most practical method to improve vitamin B12 levels are through B12 injections and B12 oral supplementation (typically capsule, tablet or in powdered form). B12 shots are, by far, the most efficient and beneficial method for Cyanocobalamin supplementation. Cyanocobalamin shots are the most common and most inexpensive types of B12 injections. Cyanocobalamin is almost exclusively the only form of B12 added to food and used in dietary supplements. Cyanocobalamin naturally is converted to Methylcobalamin through the chemical processes of the body.
Ingredients:
Cyanobalamin 1000mcg

Dementia, psychoses, and mood disturbances are but a few of the disorders which have recently been linked to possible vitamin B12 deficiencies.
Cyanocobalamin is the most commonly used form of vitamin B12. It does not occur naturally in living organisms. However, the synthetic form of the vitamin can be converted into an active form such as Methylcobalamin in animals. This results in the release of very little amounts of cyanide which is not harmful. It is more stable and can be easily crystallized. This makes it easy to purify after it has been produced through in vitro synthesis or bacterial fermentation. The cyanide ligand is replaced by other groups such as methyl which are more biologically active. It is useful in the prevention and treatment of low blood levels of the vitamin. The vitamin associates with Intrinsic Factor to help in maintaining good health of the body. Cyanocobalamin may be prescribed for treatment of a number of vitamin B12 deficiencies resulting from a variety of causes. Benefits of Cyanocobalamin include: Maintaining the cell Cyanocobalamin helps in maintaining a variety of cells in the human body. This includes formation, maintenance, and repair of cells such as the red blood cells. It also helps in the repair and sustaining nerve cells and maintaining a stronger nervous system. Formation of DNA The vitamin contributes significantly in the formation of DNA in the human body. This occurs during division of cells and Cyanocobalamin plays a central role. Deficiency of vitamin B12 may result in abnormal cell formation such as megaloblasts. This makes it important to include the vitamin in the diet. Cyanocobalamin helps in improving stamina and thus helps in relieving the body from fatigue and weakness. This helps the body withstand heavy work/ exercises. It also helps to reduce cholesterol levels in the body by controlling triglycerides levels. This contributes positively to a normal healthy heart. Moreover, the vitamin has been shown to contribute positively to individuals suffering from sickle cell anemia, Alzheimer’s disease, anemia, and breast cancer. A number of studies have also shown the vitamin to help in increased weight loss through increased fat metabolism. The supplements have been associated with several side effects such as chest pains, nausea, dizziness and fever among others following the injection. The medication comes as an injection, oral pills, and nasal drops and should be taken under directions and instructions by the physician.
