Scientists have cracked the code behind how vitamin B-12 is made, providing insight that may persuade bacteria to produce it more abundantly – potentially aiding treatment for pernicious anemia.

Researchers used anaerobic B12 production as a basis to train a beneficial bacteria to create all components necessary for its synthesis. This provided them with all of the molecular puzzle pieces needed to piece together how vitamin is created.

Why B-12?

Vitamin B12 is essential in producing red blood cells, which carry oxygen around the body. Additionally, it’s used for producing DNA and RNA that make up our genetic material. Without enough vitamin B12 in their bodies, individuals can suffer from megaloblastic anemia characterized by abnormally large red blood cells.

B12 works alongside its fellow B vitamins folic acid and B-6 to regulate levels of homocysteine, an amino acid linked with heart disease. Homocysteine can be broken down by cobalamin-dependent methyltransferase in the liver into S-adenosylmethionine (SAMe) which may help protect against cardiovascular disease; however, studies on supplement B vitamins have not consistently demonstrated their efficacy against cardiovascular disease or stroke risk.

Deficient vitamin B12 levels can lead to nerve damage in older adults. They’re most likely to appear among people who do not consume sufficient food sources of the vitamin, including meat and dairy products, while digestive disorders that impede normal digestion like Crohn’s disease or celiac disease increase their chances.

Research suggests that higher blood levels of vitamin B12 could reduce depression risk; however, more research must be completed before this can be proven.

Other research suggests that an adequate intake of vitamin B12 may reduce risks for eye diseases such as age-related macular degeneration and cataracts; however, a randomized controlled trial that assessed whether supplementing with B12, folic acid, and B6 would increase macular degeneration risk did not show any benefit from supplementation.

Observational research indicates that vitamin B12 supplements might be linked with an increased risk for certain cancers; however, more study needs to be completed in this area. People living with pernicious anemia – an uncommon congenital condition which prevents them from properly absorbing food-bound vitamin B12 – are especially prone to severe vitamin B12 deficiency; prescription drugs like metformin or proton pump inhibitors can also result in deficiency levels dropping.

What is B-12?

Vitamin B12 (cobalamin) plays an essential role in red blood cell formation, cell metabolism and nerve function, as well as the production of DNA molecules that carry genetic information within cells. Vitamin B12 can be found naturally in animal foods as well as added to certain food items like breakfast cereals or dairy products; additionally it is sold as an oral dietary supplement and even available through injection or nasal spraying.

Most Americans consume enough vitamin B12 from their diet. Data from the National Health and Nutrition Examination Surveys reveal that, on average, daily vitamin B12 intakes exceed the Recommended Dietary Allowance (2 mcg per day for adults). However, low vitamin B12 consumption may be common among certain groups – particularly lower socioeconomic status individuals, non-Hispanic blacks, and older adults who often have difficulty absorbing food-bound sources of Vitamin B12. Consequently they have increased risks for severe deficiency states due to difficulties absorbing food-bound Vitamin B12. These groups are at greater risk due to difficulties assimilating food-bound sources of Vitamin B12.

Vitamin B12 must first bind with intrinsic factor protein in the stomach for absorption; this happens when hydrochloric acid in the stomach releases it from its food source, whereupon it joins forces with intrinsic factor to be absorbed in the small intestine. People unable to access enough intrinsic factor will eventually experience severe vitamin B12 deficiency known as pernicious anemia.

Pernicious anemia can also cause neurological damage that could eventually lead to dementia and memory loss, with low levels of vitamin B12 believed to contribute. Depression may be related to low vitamin B12 levels due to reduced methyl group donors S-adenosylmethionine (SAM), which can be made available via supplementing your diet with Vitamin B12.

Vitamin B12 appears to help protect against cancer. Two early case-control studies indicate this, suggesting higher vitamin B12 intakes and blood concentrations may be related to decreased cancer risks; other research, however, has not established such a correlation. It should be interpreted with caution since other factors, such as overall diet patterns could have had an influence on these findings.

How do I get B-12?

Vitamin B12 (cobalamin) can be found in many food sources, such as meat and dairy. Together with vitamin B9 (folic acid), this nutrient works together to produce red blood cells and DNA for your body’s use – this requires maintaining optimal levels of both vitamins.

Anemia can result from deficiencies of both vitamins. B12 is essential for producing red blood cells that carry oxygen throughout your body.

Lack of vitamin B12 may result in symptoms including nerve damage, weakness, numbness and loss of balance and coordination. If this sounds familiar to you, seek medical advice immediately as deficiency anemia should initially be treated via injections followed by oral or nasal supplementation.

People most at risk of vitamin B12 deficiency include older adults who may not produce enough hydrochloric acid in their stomachs to absorb vitamin B12 from food; vegetarians and vegans who avoid animal products could also be susceptible since this vitamin can only naturally occur in animal products.

Pregnant women and breastfeeding mothers require adequate levels of vitamin B12 during gestation and breastfeeding to ensure healthy development for their fetuses. Lack of this vitamin in either can result in birth defects or developmental delays for their child.

Vitamin B12 deficiency symptoms include poor memory and thinking difficulties, fatigue, weakness and dizziness – potentially life-threatening in severe cases.

Vitamin B12 deficiency can be treated in several ways, from shots of this nutrient through pills, liquid supplements or dissolvable lozenges to multivitamin supplements containing B12. You can also find B12 in pills or liquid forms; multivitamin supplements often contain it too! You can purchase individual B12 supplements or complex formulas containing all eight of the B vitamins active and absorbable forms – these products can often be found at health food stores; some come sweetened with fruit concentrates or stevia, while others are unflavored containing only B vitamins; some brands even provide customized formulations with extra folic acid for pregnant women or those suffering from genetic conditions that affect folate metabolism.

What is B-12 M2?

When it comes to B12, one of the easiest ways to ensure you’re getting enough is through food that has been fortified with this essential nutrient. According to the NIH, vegetarians and vegans may be particularly susceptible to vitamin B12 deficiency than others; regardless of diet, however, it’s essential that blood levels be checked every few years by healthcare professionals.

As with other vitamins, B12 can be found in various food products. It’s often added to processed meats and milk products as well as fortified cereals, pasta, bread, soymilk and juices. In addition to eating fortified foods that include B12, the National Institutes of Health recommend taking supplements of either methylcobalamin or 5-deoxyadenosylcobalamin; both forms convert by your body into enzymes that convert amino acids into glucose (blood sugar).

The methylcobalamin form of B12 can be found naturally in liver and dairy foods, while 5-deoxyadenosylcobalamin forms may also be obtained through plant sources. A small clinical study demonstrated that methylcobalamin could even be delivered directly into cells using nasal mucus membrane delivery systems (see video below).

B12 stands out among water-soluble vitamins because it contains cobalt as its active metal ion; thus, it’s known as a cobalamin vitamin. Cobalamin has a complex chemical structure and plays an essential role in many biological reactions in your body, such as DNA synthesis and protein metabolism.

Studies have demonstrated that high homocysteine levels may increase risks of Alzheimer’s and dementia. They’re also linked with cardiovascular disease and stroke risks; and may play a part in stroke and heart attack outbreaks.

Researchers led by Professor Martin Warren of the University of Kent recently asked schoolchildren to grow garden cress seedlings in water with different concentrations of B12 before washing and testing for the presence of vitamin. Scientists discovered that cress seedlings absorbed and stored vitamin from its environment; their results confirmed that plant tissues can synthesize it while leaf cells contain specialized structures capable of storing it.
