Boost absorption When purchasing a vitamin B12 supplement, it is important to check that it contains the activated form of the nutrient, called methylcobalamin. Other forms of vitamin B12, such as cyanocobalamin, have to be converted to methylcobalamin in order for it to be correctly and optimally utilised by the body. Activated vitamin B12 supports haemoglobin formation and the metabolism of proteins, carbohydrate and fats, aids healthy red blood cell production and blood health, supports cardiovascular and nervous system health and cognitive function, and boosts energy production. Recent discoveries • A recent study revealed that even minor B12 deficiencies can lead to cognitive impairments and memory challenges. The research indicates that sufficient levels of B12 can not only counteract these issues but may also play a role in mood regulation, further proving its centrality to brain health. • With the rise of plant-based diets, scientists underscore the necessity of B12 supplementation to ensure optimal health for vegetarians and vegans. The beauty of B12 is truly multi- faceted, spanning from cellular energy to cognitive wellbeing.
Also known as cyanocobalamin or cobalamin, vitamin B12 was first identified in the 1940s, when it was discovered that it cured pernicious anaemia, a potentially fatal disorder affecting primarily older adults. It is found naturally in dairy products, offal (liver, heart and kidneys), eggs, beef, oysters, brewer’s yeast and seafood. Vitamin B12 is required for many essential processes in the body, including cell replication, especially of red blood cells, as well as helping to convert food to energy, processing fats and carbohydrates, supporting the proper functioning of the nervous system, and facilitating the manufacturing and protection of DNA and RNA. It also plays a critical role in processing and regulating homocysteine, an amino acid-like substance that is linked to an increased risk of heart disease; vitamin B12 works with folic acid to lower this risk. Vitamin B12 has specific benefits for the health of the nervous and immune systems, with research suggesting that low levels may be a factor in a number of neurological disorders, including dementia, tinnitus and Alzheimer’s Vitamin B12 is found naturally in a range of foods, but it is not well absorbed, especially in people over 50.
disease. It is a component of myelin, the sheath or covering that protects the nerves. A long-term deficiency can cause
irreversible nerve damage. Risk of deficiency
Although many foods, such as breakfast cereals, are now fortified with vitamin B12, it remains very poorly absorbed by many people, or not absorbed at all; vegetarians and especially vegans, are at risk of a deficiency and should take a supplement. People with ulcers, Crohn’s disease or other gastrointestinal disorders are at risk, as are those taking certain prescription medications, including anti-epilepsy drugs and long- term use of antibiotics. Excessive alcohol also hinders absorption of vitamin B12. A deficiency can also occur in people who cannot produce intrinsic factor, a protein which should be made in stomach lining cells that allows vitamin B12 to be absorbed in the blood. Many people over age 50 will lose their ability to produce sufficient gastric acid and pepsin, which is the enzyme required to separate B12 from food. This can result in too many bacteria in the stomach that are usually destroyed by stomach acid which then use up dietary vitamin B12, leaving less for the body to use. As a result, they need to take supplements.
