The final structure for vitamin B12 was discovered by Dorothy Hodgkin for which she won the Nobel Prize in How the Body Uses Vitamin B12 Cyanocobalamin To allow the body to assimilate the useful form of vitamin B12, the body must first process the cyano part and turn the cyanocobalamin into methylcobalamin which is the bio-active form of vitamin B12 that the body can instantly use.
Then the vitamin B12 is ready to help in the thousands of processes that help protect the bodies nervous system, increase cognitive abilities, produce DNA, build muscle mass, cell growth, protein and tissue synthesis, turn food into fuel, help produce red blood cells and much more.
Vegan Positives for Vitamin B12 Cyanocobalamin. Vegan Negatives of Cyanocobalamin. Summary Vitamin B12 cyanocobalamin is vegan friendly, lower priced and the most stable form of vitamin B It can be taken orally or by injection and there has been no upper limit of toxicity established, making vitamin B12 a safe vitamin to supplement. It is water soluble and all unneeded vitamins are excreted through urination.
Some people absorb different forms of B12 better than others, which is why anyone can suffer from low B12, meat eaters and vegans can both be vitamin B12 deficient. Individuals with deficiencies must find out which form of vitamin B12 supplement is best for them. Cyanocobalamin remains very effective for healthy people supplementing their daily requirement or treating vitamin B12 deficiencies and is globally prescribed to treat vitamin B12 deficiencies. Once your vitamin B12 deficiency is stabilized, injection frequency can often be reduced.
Of course, this depends upon the cause of your deficiency such as malabsorption, pernicious anemia and other conditions that create vitamin B12 deficiencies and if the cause has been effectively treated.
Always consult your doctor or healthcare professional when supplementing any vitamin. Tell them all over the counter and prescription medicine you are taking before you implement a supplementation program and then keep them informed of all positive and negative effects.
Vitamin B12, also known as cobalamin, is an important water-soluble vitamin involved in red blood cell production, brain health, and DNA synthesis 1. A deficiency in this key vitamin can cause serious symptoms, including fatigue, nerve damage, digestive issues, and neurological problems like depression and memory loss 1. Therefore, many people turn to vitamin B12 supplements to help meet their needs and prevent a deficiency.
This article examines the main differences between methylcobalamin and cyanocobalamin — two of the most common sources of vitamin B12 found in supplements. Vitamin B12 supplements are typically derived from two sources: cyanocobalamin or methylcobalamin. However, each have a different molecule attached to the cobalt ion. While methylcobalamin contains a methyl group, cyanocobalamin contains a cyanide molecule. Unlike cyanocobalamin, methylcobalamin is a naturally occurring form of vitamin B12 that can be obtained through supplements, as well as food sources like fish , meat, eggs , and milk 3 , 4.
Cyanocobalamin is a synthetic form of vitamin B12 found only in supplements, while methylcobalamin is a naturally occurring form that you can get through either food sources or supplements. Some studies suggest that your body may absorb cyanocobalamin slightly better than methylcobalamin. Conversely, another study comparing the two forms reported that about three times as much cyanocobalamin was excreted through urine, indicating that methylcobalamin may be retained better within your body 6.
However, some research suggests that differences in bioavailability between the two forms may be insignificant and that absorption could be influenced by factors such as age and genetics 7 , 8. Unfortunately, recent research directly comparing these two forms of vitamin B12 is limited. Additional studies are needed to measure the absorption and retention of methylcobalamin versus cyanocobalamin in healthy adults.
Research shows that cyanocobalamin may be absorbed better in your body, while methylcobalamin likely has a higher retention rate. Other studies have found that the differences in absorption and retention are minimal. When you ingest cyanocobalamin, it can be converted to both of the active forms of vitamin B12, methylcobalamin and adenosylcobalamin. Deficiencies in both forms of vitamin B12 can increase your risk of neurological issues and adverse side effects Some researchers recommended treating vitamin B12 deficiencies with either cyanocobalamin or a combination of methylcobalamin and adenosylcobalamin due to distinct properties of these latter two forms 9.
Professor Martin Warren, who led the research, said: 'This is a really exciting time in the biological sciences -- one where our knowledge can be applied with the emerging discipline of synthetic biology to produce strains of bacteria that make enough B12, and other vitamins, for use in medicine and other sectors, such as feed for livestock.
