Doctor insights on:
Yes, however...: You don't say which medication but it is safe to take B12 with all medications, but it should not be taken at the same time as tetracycline (take at least an hour apart). Many medications reduce absorption & thus increase our need for B12. I advise sublingual or chewable methylcobalamin.

Why deficient?: Thanks for writing. I trust this is laboratory-proved. You are in danger. If you have become B12 deficient through a vegetarian diet, i hope you'll reconsider this lifestyle, which despite much hype actually offers little benefit and many dangers, or that you'll supplement. If you have a problem absorbing B12 (several possibilities), it's a lifetime on injectable b12, which isn't bad. Good luck. ...Read more

Nothing: Why would you use this???? It is probably low potency. B12 is cheap. Why inject it? Most patients today are given a daily 1000mcg "nugget" to swallow. It is cheap and completely free of side effects. What is the indication? This is a long-term therapy, not an occasional treatment. ...Read more
B12 NOT toxic: Cobalamin (or vitamin b12), is a water-soluble vitamin with a key role in the normal functioning of the brain and nervous system, and for the formation of blood. It is one of the 8 b-vitamins. It is normally involved in the metabolism of every cell of the human body, especially affecting dna synthesis and regulation, but also fatty acid synthesis and energy. Vitamin B12 has extremely low toxicity. ...Read more
Similar: The methyl form is biologically active, and will directly interact with receptors, but in most cases, the body will convert the other form readily, so in the end, there is equivalency. ...Read more
Methylcobalamin: Methylcobalamin is by far the best form of vitamin b12. This is the co-enzymated active form that our bodies use. When we take Cyanocobalamin our bodies must first convert it into methylcobalamin, so it is better to take the active form and save your body the trouble of making this conversion. See http://www.Naturalnews.Com/027045_vitamin_b12_cyanocobalamin_methylcobalamin.Html. ...Read more
I have an unopened vial of cyanocobalamin that is a couple years expired. What would happen if I used it?
DO NOT USE IT: Never use expired medication for any purpose, especially injectable medications. ...Read more
I have been prescribed Methylcobalmin 1000mcg/ml injection but I am able to get either cyanocobalamin or mecocobalamin.Could I use either of the two?
Yes, probably : Cyanocobalamin is an artificial B12 which must be activated in the liver. Methylcobalamin or Mecobalamin is a biologically active form. Your doctor may have a reason for preferring the active form. BTW, Mecobalamin is fully absorbed through the mucous membranes of the mouth, but cyanocobalamin is not and must be absorbed through the gut. ...Read more

No, however...: A famous saying is "the poison is in the dose." Cyanide naturally occurs in trace amounts in many foods including almonds, soy and spinach. The amount of cyanide when we metabolize cyanocobalamin is tiny and it's detoxified by our body. However, we need to convert it to the active form, methylcobalamin, so better to take that form so we don't have to convert it and not waste our detox resources. ...Read more
Cobalamin: Cyano c. is inactive form. Hydroxy c. is natural form. Methyl c. is an active form. Adenosyl c. is also an active form of c. but unlike the others, it is not available by injection. ...Read more
Methylcobalamin: Methylcobalamin is by far the best form of vitamin b12. This is the co-enzymated active form that our bodies use.When we take Cyanocobalamin or hydroxycobalamin our bodies must first convert these into methylcobalamin, so it is better to take the active form and save your body the trouble of making this conversion.See my comment for a link to more info:. ...Read more
Why do that?: If your physician recommended it to be done this way i would ask them for their reasoning. Otherwise, i don't see the logic in doing 2 separate injections of cobalamin as you suggest. I would choose one formulation and provide my patient with a single injection with the proper amount i wanted them to receive and be done. ...Read more
B12 as methylcobalamin or B12 as cyanocobalamin - which one is safer/better and in what form : pills or sublingual?
No difference: 2 mg oral is supposed to be as good as sub lingual. I usually recommend 1.7 mg SL liquid every week for 2 months then once every 2 weeks thereafter. I recommend maintaining a level of 550 at all times. One should also check folate (folic acid) level and make sure that is OK. If anemic and you are replacing B12 its wise to check for low potassium as correction of the anemia can deplete K+ stores. ...Read moreSee 1 more doctor answer
Can cyanocobalamin be lethal or harmful to the human body if it cannot process the cyanide component? If yes, should one avoid cyanocobalamin?
No worries: Cyanocobalamin has trace amounts of cyanide; the usual dose is 1 mg (one thousandth of a gram) or less; only some of that is the cyanide,which is readily detoxed by several mechanisms so everyone can likely clear it. There is cyanide in almonds,bamboo shoots, cassava and other foods. I advise taking methylcobalamin, the active form we convert the cyano form to, as some have trouble converting it. ...Read more
Do all fortified foods contain cyanocobalamin or do some contain methyl or hydroxo, and which natural sources of b12, are the most bioavailable?
Most cyanocobalamin: No way of knowing if "all" have the cyano form but I believe virtually all have that form as it is the least expensive and most widely available. But methylcobalamin is the optimal form for supplementation- see http://tinyurl.com/h7scsna Some foods contain higher concentrations of B12 but the form found in food is hydoxycobalamin so all equally bioavailable. See http://tinyurl.com/j7npwg3 ...Read more
