99 percent of the Vitamin B12 Supplements on the Market Contains Cyanide

Unknown to most consumers, cyanide is found in a wide range of vitamins and foods in a form known as cyanocobalamin. On its own, the cyanide has a very low potential to do harm because it is organically bound to cobalamin (vitamin b12) — that is, as long as everything is working correctly and that person hasn’t already been burdened with environmental chemical exposures from cyanide, and related xenobiotic compounds.

Cyanocobalamin is actually found in 99% of the vitamins on the market which contain B12, as it is relatively cheap (recovered from activated sewage sludge or produced through total chemical synthesis), and stable (non-perishable). Despite its wide usage, it is not an ideal form of vitamin b12, as the cyanide must be removed from the cobalamin before it can perform its biological indispensable roles within the body. While there is plenty of research on the potential value of cyanide-bound vitamin B12, it does have potential to do harm.

In fact, when a person is poisoned with cyanide, as sometimes happens following smoke inhalation, and they are rushed to the emergency room, what do they give them to remove the cyanide? Hydroxocobalamin — a natural form of vitamin b12 — which readily binds with the cyanide, becoming cyanocobalmin (which sequesters the cyanide and puts it into a form ideal for detoxification and elimination), which is then rapidly excreted from the body via the lungs and kidneys.

Those with a higher body burden or higher cyanide exposure, such as smokers, are less likely to be able to effectively detoxify the additional cyanide they consume through their diet or supplements, making the seemingly benign levels found in some vitamins and foods a real problem.

Indeed, this is not the first time the question of the potential toxicity of cyanocobalamin has been raised. As far back as 1992, a report was published in the Journal of the Royal Society of Medicine arguing for its withdrawal from use in vitamin therapy. Another study published in 1997 in the journal Blood, found that cyanocobalamin “antagonizes vitamin B12 in vitro and causes cell death from methionine deficiency.”

Cyanide in non-vitamin form, of course, is extremely toxic and a poster child of sorts, among poisons. It only takes 6.44 mg per kilogram, or 1.61 mg to kill 50% of your average-sized (500 gram) rats through the oral route of exposure. The margin of safety (as defined by the LD50) for cyanocobalamin, on the other hand, is approximately 1,000 times higher.

An entirely different approach to maintaining adequate vitamin B12 levels is through supporting the microflora in the gut, as these beneficial bacteria are proficient in producing this indispensable vitamin. Lactobacillus reuteri, for instance, has been studied for its vitamin B12-producing properties.

Other dietary sources of biologically active B12 include white button mushrooms, spirulina and chlorella. The ideal supplemental form of supplemental vitamin B12 is methylcobalamin, which while more expensive, is capable of absorbing efficiently sublingually and is cell-ready as a methyl donor. It should also be noted that the drug category known as proton pump inhibitors (acid blockers for reflux) prevent vitamin B12 absorption and microwaving food deactivates this vitamin, as well.

    Excellent advice. I’ve known about the superiority of methylcobalamin for years, and it’s the only kind I purchase; however, I was not aware that cyanocobalamin contained cyanide. Thanks for enlightening me on this.

    Apricot pits also contain a form of cyanide; they are used as a source of nitrilosides (amygdalin, laetrile) used in natural treatment of cancer. Watch G. Edward Griffin’s video, A World Without Cancer: http://www.youtube.com/watch?v=JGsSEqsGLWM

    B12: Cyanocobalamin and Methylcobalamin

    Cyanocobalamin vs. methylcobalamin makes an interesting comparison. Methylcobalamin is slightly more biologically active than cyanocobalamin, and is retained in the body slightly better. However, methylcobalamin is not well absorbed when taken orally, yet cyanocobalamin is. The very slight superiority of methylcobalamin over cyanocobalamin once it is in the body is completely negated by cyanocobalamin’s superior absorption. The companies that put methylcobalamin in their supplements and make a big deal about it being a better quality than cyanocobalamin don’t tell you that all the studies that show its superiority were done by injected methylcobalamin not oral methylcobalamin. To benefit from methylcobalamin taken orally, several thousand micrograms per day must be taken to equal the benefit of cyanocobalamin.
