Serum aluminum accumulation with Cyano B12 Injections

[DFord]

Cyanocobalamin injections and aluminum as a preservative - anyone finding they are accumulating aluminum in their blood?

What are drawbacks of MethylCobalamin with Benzyl Alcohol preservative, or

HydroxoCobalamin with MethylParaben and PropylParaben as preservatives?

[fbirder]

Cyanocobalamin injections do not use aluminium as a preservative. Here are the ingredients of the vial - dailymed.nlm.nih.gov/dailym...

Cyanocobalamin, water, benzyl alcohol, sodium hydroxide and hydrochloric acid.

You may be confused by the fact that some cyanocobalamin preparations say that they contain a certain (tiny) amount of aluminium. That is because some US jurisdictions insist on every product that might possibly contain aluminium display how much it contains. The amount they list is the lowest amount they can measure. It means that, while there is zero aluminium in there, they can't guarantee there isn't the tiniest smidgen of it.

I've never heard of parabens being used with hydroxocobalamin. It definitely doesn't happen in the EU, because those chemicals are being phased out in the face of a probable ban in the near future. However, it wouldn't surprise me to hear that they are used in the USA.

Personally, I would use cyanocobalamin out of the choices you list.

This link says it can include aluminum, but most other sources say it does not, and the vials I have say Benzyl Alcohol.

even if the product you have does contain aluminium the article implies that the risk only arises where the individual concerns has impaired kidney function and is taking other drugs containing high dosing of aluminimum. It implies that this is only a real concern with premature neonates - probably because these are likely to be treated with other drugs containing aluminium and don't have full kidney function
