Shots, Shots, Shots – Vitamin B-12 thats is!

Recently, a number of  patients have inquired in regards to Vitamin B-12 shots, asking if they are helpful to increase energy levels.  Well, lets take a look at closer look at Vitamin B-12 to get a better understanding of what it is, who should take it, and which form of it to use.

Vitamin B-12, also called cobalamin, is a water-soluble vitamin, it is key for brain function, nervous system, and for blood synthesis. It is one of the eight vitamins in the Vitamin B family. vitamins.  Animals, plants, and fungi do not produce this vitamin, mainly it is made by bacteria.  Many foods are a natural source of B12, not because these foods produce it, but because of bacterial symbiosis. “The vitamin is the largest and most structurally complicated vitamin and can be produced industrially only through bacterial fermentation-synthesis.” (1)

What is Vitamin B-12 used to treat (1):

  • B12 deficiency
  • cyanide poisoning
  • hereditary deficiency of transcobalamin
  • It is given as part of the Schilling test for detecting pernicious anemia

Who is most at risk of a Vitamin B-12 Deficiency:

  • Elderly patients
  • Strict Vegetarians

We Get Vitamin B-12 in our diet, what are the recommended dietary amounts (2)

According to the Mayo Clinic, recommended dietary amounts (RDAs) are 2.4 micrograms daily for ages 14 years and older, 2.6 micrograms daily for pregnant females, and 2.8 micrograms daily for breastfeeding females. Those over 50 years of age should meet the RDA by eating foods reinforced with B12 or by taking a vitamin B12 supplement. Supplementation of 25-100 micrograms daily has been used to maintain vitamin B12 levels in older people. A doctor and a pharmacist should be consulted for use in other indications.

What if the doctor checks my blood test and I have a Vitamin B-12 deficiency, how will I be treated?  Here are the possibilities: (2)

  • 125-2,000 micrograms of cyanocobalamin has been taken by mouth daily for up to 2.5 years or longer.
  • Five hundred micrograms of sublingual (under the tongue) vitamin B12 has been used daily for up to four weeks
  • by IV (through the veins): 1,000 micrograms of intramuscular cobalamin once daily for 10 days (after 10 days, the dose was changed to once weekly for four weeks, followed by once monthly for life)
  • intramuscular injections, 1,000 micrograms cyanocobalamin given on days 1, 3, 7, 10, 14, 21, 30, 60, and 90 of treatment

Injectable form has great absorption, because goes directly into the blood stream. After a doctor determines a deficiency, injectible Vitamin B-12 is prescribed by physician, the prescription is filled at the pharmacy.  The patient takes the vial to their appointment, and injections are done in the doctor’s office.

I heard that the Cyanocobalamin form for B-12 is not as good as the Methylcobalamin form

There has been literature circulating that methylcobalamin is the more natural form of B-12. The body can break it down more easily and there is no cyanide involved. Cyanide is considered a a poison, but the amounts in cyanocobalamin were never said to be dangerous.

Methylcobalamin has several possible key advantages over cyanocobalamin: (4)

* Increased absorption
* Better retention in tissues
* Contains no cyanide
