Does B12 come from cyanide?
While methylcobalamin contains a methyl group, cyanocobalamin contains a cyanide molecule. Cyanocobalamin is a synthetic form of vitamin B12 that's not found in nature ( 2 ). It's used more frequently in supplements, as it's considered more stable and cost effective than other forms of vitamin B12.
What vitamin contains cyanide?
vitamin b12The form of vitamin b12 used in nearly all mass-market vitamins is called cyanocobalamin. This is a cyanide-based form of b12 and it is the most common form found on the market! Unknown to most consumers, cyanocobalamin is found in a wide range of vitamins and foods as a synthetic additive.
Is cyanocobalamin the same as cyanide?
Cyanocobalamin is broken down into cobalamin and cyanide. Yes, you read that correctly. That is the same deadly cyanide stuff that we have heard about. Researchers have suggested that there could be a buildup of cyanide in the tissues, especially in smokers from people using the cyanocobalamin form of B12.
What are the ingredients in B12?
Because vitamin B12 contains the mineral cobalt, compounds with vitamin B12 activity are collectively called “cobalamins” [1]. Methylcobalamin and 5-deoxyadenosylcobalamin are the metabolically active forms of vitamin B12.
What is the safest form of B12?
Cyanocobalamin B12 contains a cyanide molecule that gives it stability in products and the body. Cyanide is a poison, of course, but in the minuscule quantities found in Cyanocobalamin, this is of no consequence – it's perfectly safe to take!
Can you take too much vitamin B12?
Since B12 is a water-soluble vitamin, it's generally considered safe, even at high doses. No Tolerable Upper Intake Level (UL) has been established for B12, due to its low level of toxicity. UL refers to the maximum daily dose of a vitamin unlikely to cause adverse side effects in the general population.
What does cyanide do to the body?
Cyanide poisoning is poisoning that results from exposure to any of a number of forms of cyanide. Early symptoms include headache, dizziness, fast heart rate, shortness of breath, and vomiting. This phase may then be followed by seizures, slow heart rate, low blood pressure, loss of consciousness, and cardiac arrest.
What is the best type of B12 to take?
The vitamin itself is available in several forms, most commonly methylcobalamin and cyanocobalamin. However, the best option is clear. “Go for the methylcobalamin form of vitamin B12 because it is absorbed much better by the body than other forms of vitamin B12,” says Dr. Boyer.
What is synthetic B12 made from?
"The most common form of B12 in the world is entirely synthetic. We make it from hydrogen cyanide," said Brecka, who describes himself in his LinkedIn profile as founder of a Florida-based health business. "It's called cyanocobalamin.
What medications should not be taken with B12?
Certain medications can decrease the absorption of vitamin B12, including: colchicine, metformin, extended-release potassium products, antibiotics (such as gentamicin, neomycin, tobramycin), anti-seizure medications (such as phenobarbital, phenytoin, primidone), medications to treat heartburn (such as H2 blockers ...

What products contain cyanide?
Cyanide is contained in cigarette smoke and the combustion products of synthetic materials such as plastics. Combustion products are substances given off when things burn. In manufacturing, cyanide is used to make paper, textiles, and plastics. It is present in the chemicals used to develop photographs.
Where can cyanide be found?
Low levels of cyanides are found in nature and in products we commonly eat and use. Cyanides can be produced by certain bacteria, fungi and algae. Cyanides are also found in cigarette smoke, in vehicle exhaust, and in foods such as spinach, bamboo shoots, almonds, lima beans, fruit pits and tapioca.
What does cyanide do to the body?
Cyanide poisoning is poisoning that results from exposure to any of a number of forms of cyanide. Early symptoms include headache, dizziness, fast heart rate, shortness of breath, and vomiting. This phase may then be followed by seizures, slow heart rate, low blood pressure, loss of consciousness, and cardiac arrest.
What is the best supplement for B12?
The ideal supplemental form of supplemental vitamin b12 is methylcobalamin, which while more expensive, is capable of absorbing 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.
What is the most common cause of inborn errors of B12 metabolism?
In fact, defects in MMACHC are believed to be the most common cause of inborn errors of b12 metabolism. Those who suffer from MMACHC-related ...
Is cyanocobalamin a toxicity?
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 Journal of the Royal Society of Medicine arguing for its withdrawal from use in vitamin therapy, especially with smokers experiencing neuropathy. Another study published in 1997 in the journal Blood, found that cyanocobalamin "antagonizes vitamin B12 in vitro and causes cell death from methionine deficiency."
Is Cyanocobalamin Really A Health Concern?
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 cyanide-free form of vitamin b12 -- which readily binds with the cyanide, becoming cyanocobalamin, which sequesters the cyanide, putting it into a less toxic form that can be more readily eliminated from the body via the lungs and kidneys. You can learn more about this cyanide detoxification approach on Emergency Physician Monthly's site here.
What is the name of the vitamin that converts to B12?
Technically, that’s correct. Cyanocobalamin is a form of vitamin B12 which our bodies can convert into the same B12 we’d pick up from food. One step in that process is changing cyanocobalamin to hydroxocobalamin.
How does the body deal with cyanide?
The body can deal with small amounts of cyanide, usually by using sodium thiosulfate, converting the cyanide ions to thiocyanate, which you then excrete.
Is cyanocobalamin safe for anemia?
Cyanocobalamin is safe, and found in food additives, health supplements, and the injections that doctors give patients with anemia. What’s more, the reaction can work the other way. Hydroxocobalamin is sometimes used to treat cyanide poisoning. When it gets into the blood stream, it can absorb cyanide atoms in the body.
Can B12 cause a heart murmur?
This results in pernicious anemia, which starts with fatigue and depression and can get bad enough to bring on deterioration of the spinal cord and a heart murmur. Doctors treat the condition with what they say is a vitamin B12 shot. Technically, that’s correct.
Can you take B12 with B12?
So you will probably take a little cyanide with your B12, but you can also take B12 to suck up cyanide.
Is there cyanide in vitamin B12?
There's Cyanide in Artificial Vitamin B12, And That's Okay. When you get a shot of vitamin B12, you’re also getting traces of cyanide in the mix–although it would be equally accurate to say that there’s artificial B12 in your antidote to cyanide.
Can you see B12 with your naked eye?
Nothing you can see with the naked eye can manufacture vitamin B12 from scratch–which is a shame, because we all need it. Instead, we have bacteria to thank for keeping us alive: They can form B12, and we either eat them or eat things that eat them.
How does B12 get into the body?
The body releases B12 from its package (the food you eat) through chewing and digestion through stomach acid and enzyme activities. Then a special protein in the saliva and stomach picks up the B12 and takes it to the gastrointestinal (GI) tract (your intestines). Once in the GI tract, the “freed” B12 will go to the cells either with another protein (intrinsic factor) or “float” across the cell barrier in a process called diffusion.
What is the role of B12 in the body?
Vitamin B12 plays an important role in the body. It has been found to help with various systems within the body including but not limited to energy, sleep, memory, increased homocysteine (an indicator of inflammation), anemia (low red blood cell count), dementia, stroke, and improved mood.
What vitamin is needed for dementia?
Metabolic vitamin B12 deficiency: a missed opportunity to prevent dementia and stroke.
What does the word "methyl" mean in front of methylcobalamin?
Tip 5: The word “methyl” in front of methylcobalamin does not mean this form of B12 provides the body with more methyl groups for methylation. In actuality, it helps the body bring the B12 to the outside of the cell where the body cuts off the methyl group and brings it inside the cell to participate in its various jobs. More on this topic in an upcoming blog post!
How many different types of B12 are there?
There are three different types of Vitamin B12:
Where is adenosylcobalamin found?
Adenosylcobalamin is found primarily in animal meat especially in the liver.
Is B12 a protein?
Tip 2: B12 is heavily concentrated in animal protein. If you are a vegan or vegetarian, it is especially important that you monitor your B12 and B12 metabolite levels (e.g. methylmalonic acid) particularly if you are experiencing a decrease in energy, hair loss and/or difficulty sleeping.
What is the most commonly used vitamin B12?
Of those, cyanocobalamin, is by far the most commonly used one. In fact, over 65% of the multivitamin supplements we’ve analysed contain vitamin B12 in this form.
How much cyanide can you ingest?
In order to get this amount of cyanide, that person will have to ingest 7 kilograms of cyanocobalamin or approximately 3,500 vitamin B12 tablets in a single day.
What is the antidote for cyanide?
Amyl nitrate is the antidote of choice, followed by intravenous sodium nitrite and then sodium thiosulfate. It is interesting that decreasing supplies of laboratory amyl nitrate in the first aid kit often do not tally with the number of accidental cyanide incidents, but that is a whole different story. Is the cyanocobalamin form of vitamin B12 ...
How much cyanide is needed to extinguish life?
We know that it takes 1 mg of cyanide per kilogram of body weight to extinguish life in a human being 3. The average daily dose of cyanocobalamin in the products we have analyzed is 0.14 mg. The highest dose of cyanocobalamin we have found in the products we have analyzed is 1 mg.
How does cyanide affect frogs?
Cyanide exerts its toxic effect by inhibiting a mitochondrial enzyme called cytochrome c oxidase 1. If you have ever applied cyanide to frog skin in biology class, you would see that the effect is almost immediate. This effect is known as histotoxic hypoxia because the cells are unable to get oxygen.
Is cyanocobalamin a poison?
In fact, over 65% of the multivitamin supplements we’ve analysed contain vitamin B12 in this form. Unfortunately, during absorption by the digestive system , cyanocobalamin has a disturbing tendency of releasing cyanide, which in high quantities can be a powerful poison.
Is apple core more toxic than vitamin B12?
This is equal to the same amount of cyanide poison in 18 apple cores. Therefore, apple cores are more toxic than vitamin B12 tablets containing cyanocobalamin by a factor of 195. So the answer to the original question is yes, the cyanocobalamin form of vitamin B12 is toxic but, in practical terms, it would be very difficult to ingest enough ...
How does B12 help remove hydrogen cyanide from the body?
In the body the cyanide ion is exchanged with the hydroxyl group of hydroxycobalamin, producing cyanocobalamin. The cyanocobalamin can now be safely flushed from the body. Many commercial vitamin B12 supplements actually contain cyanocobalamin. This raises the question of the toxicity of cyanocobalamin. In the quantities taken for regular supplementation is it usually not toxic. Exceptions are heavy smokers who already have chronic cyanide toxicity from cigarette smoke, and sufferers of Leber's hereditary optical neuropathy. If you want to completely avoid any amounts of cyanide, use supplements containing hydroxycobalamin or methylcobalamin. Vitamin B12 is very nontoxic. The hydroxycobalamin dose administered at the scene to smoke inhalation victims is 5 grams for an adult. That is about 2 million times the daily dose needed for an adult (2.4 micrograms).
What is the greatest risk of cyanide poisoning?
The greatest risk for cyanide poisoning in the United States comes from smoke inhalation. Many common household materials like wool, paper and plastics produce hydrogen cyanide when burned under low-oxygen conditions. Smoke inhalation thus presents a greater threat than actual burning in a fire, and hydrogen cyanide toxicity through smoke inhalation is a common occupational hazard for firefighters.
Can cyanide be poisoned?
Cyanide exposure not occurs not only from intentional poisoning. Cyanide (hydrogen cyanide) and cyanide-containing chemicals are used in mining, in acrylic nail removal and sometimes in fumigation. Most people have heard that apple pits contain cyanide. This is true, although the amount is very small. The cyanide is bound to a sugar called amygdalin. The apple pit has to be broken or crushed to release the amygdalin into the body.
What is cyanide toxic?
Cyanide toxicity can occur from a range of different exposures, including smoke inhalation from burning plastics in house fires, intentional ingestions in suicide attempts and industrial exposures among individuals working in the jewelry, photography, metallurgy or textile industries [1,2].
What are the symptoms of cyanide poisoning?
ADVERTISEMENT. The symptoms of cyanide toxicity include nausea, vomiting, headaches, confusion and dyspnea ultimately leading to seizures, coma and death.
What is the role of B12A in the body?
ADVERTISEMENT. How It Works. Hydroxocobalamin (vitamin B12a) has a central cobalt atom that binds cyanide ions, forming cyanocobalamin (vitamin B12), which is nontoxic and renally excreted. Hydroxocobalamin can rapidly enter the mitochondria and bind cyanide at the site where it is toxic, thus restoring oxidative metabolism. Major Indications.
Can cassava cause neuropathy?
Ingestion of improperly prepared cassava, is one cause, and can lead to a demyelinating disorder called tropical ataxic neuropathy. Cyanide is also present in trace amounts in fruit seeds, but rarely poses a health risk.
Is cyanide iatrogenically or iatrogenically?
It can also occur iatrogenically from prolonged nitroprusside infusion. In water, cyanide exists primarily as HCN (hydrogen cyanide), which can rapidly cross cell membranes, but is in equilibrium with cyanide ions (CN–).
Is cyanide a safe drug?
Cyanide toxicity can be quickly fatal, but there is a simple, safe treatment that can reverse its toxic effects. For many years, cyanide toxicity was treated with multi-component cyanide antidote kits. Now there is a newer, safer agent that converts the mitochondrial toxin, cyanide, into the benign chemical cyanocobalamin, or vitamin B12.
