Quick Take
A Facebook video claims that the intake of vitamin B12 is dangerous due to its cyanide content. We fact checked the claim and found it to be False.
The Claim
The claim in facebook video by Minddss, with a title “Gary Brecka on the Deadly Facts of B12.” During the 90-second clip, Gary Brecka, presents his argument against cyanocobalamin, a form of B12, claiming it to be harmful. Brecka describes B12 as containing the cobalt metal and discusses its synthetic production using hydrogen cyanide. He alleges that vitamins containing this synthetic form of B12 can harm DNA, deprive cells of vital nutrients, and hinder oxygen absorption. He advises viewers to check their vitamin labels and discard any containing cyanocobalamin, saying it is not naturally occurring and contains cyanide.
Fact Check
What is vitamin B12?
Vitamin B12, also known as cobalamin, is a water-soluble vitamin that plays a crucial role in many bodily functions. It is essential for the formation of red blood cells, DNA synthesis, proper neurological function, and the metabolism of fatty acids and amino acids. Vitamin B12 is primarily found in animal-based foods such as meat, fish, eggs, and dairy products, although it can also be obtained through fortified foods or supplements by vegetarians and vegans.
How vitamin B12 supplements are made?
Vitamin B12 supplements are typically made through a synthetic process. The production starts with the cultivation of bacteria that naturally produce vitamin B12. These bacteria are then fermented in large vats under controlled conditions. After fermentation, the vitamin B12 is extracted and purified. It can then be processed into various forms, such as cyanocobalamin, which are commonly used in supplements. Finally, the B12 is often combined with other ingredients and formed into tablets, capsules, or liquid forms for consumption as supplements.
How are cyanocobalamin made?
Cyanocobalamin, a synthetic form of vitamin B12, is produced by combining cyanide with cobalamin, the natural form of B12. Despite containing cyanide, the amount is minuscule and poses no harm at typical doses. Cyanocobalamin is commonly used in supplements and fortified foods to address B12 deficiency. Its synthesis involves fermentation of bacteria that naturally produce B12, followed by extraction, purification, and formulation into various supplements. It supports red blood cell formation, DNA synthesis, and neurological function.
Is the cyanide found in cyanocobalamin vitamin B12 harmful to us?
The cyanide present in cyanocobalamin is not harmful at the doses found in B12 supplements which can harm DNA or hinder oxygen supply. Cyanocobalamin contains a cyanide molecule, yet in trace amounts that are easily metabolised and eliminated by the body without causing harm. The body’s detoxification mechanisms effectively neutralise cyanide, ensuring safety. While cyanide can be toxic in larger quantities, the minute levels in cyanocobalamin supplements are considered safe for consumption even in high doses and are not associated with adverse effects. Thus, when taken according to recommended dosages, cyanocobalamin supplements pose no significant risk to human health.
General Physician Dr Kashyap Dakshini informs, “Cyanocobalamin (Vitamin B12) supplements do contain cyanide but the amount is not harmful to health. When Cyanocobalamin supplements are taken under medical supervision in the prescribed dose by a qualified doctor, they do not cause any adverse effects.”
How much cyanide is found in vitamin B12 supplements?
The amount of cyanide found in vitamin B12 supplements is extremely small, typically measured in micrograms (µg) per dosage. For example, in cyanocobalamin supplements, which contain a cyanide molecule, the cyanide content is typically less than 20 micrograms per tablet or capsule. This amount is considered safe for consumption and is well below levels that could pose a risk to human health. The body can efficiently process and eliminate such trace amounts of cyanide without causing harm.
According to Clinical Nutritionist Nidhi Sarin, cyanocobalamin, also known as Vitamin B12, is safe for consumption. The amount of cyanide present in the cyanocobalamin we consume is minimal and not harmful. Any cyanide consumed in such small quantities is expelled from the body through urine. Cyanocobalamin is typically found in supplements and, when combined with a healthy diet, helps to boost B12 levels in the body.
In everyday foods like almonds, millet sprouts, lima beans, soy, spinach, bamboo shoots, and cassava roots, small amounts of cyanide can naturally occur. However, these levels are typically more than the levels present in vitamin b 12 and both are not harmful to health. Cyanide is present as part of sugars or other compounds found naturally in these foods. When consumed in normal amounts, the cyanide content in these foods poses no significant risk to our health.
