Vitamin B12 is an essential nutrient, a form of cobalamin required for the creation of healthy red blood cells, proper nervous system function and DNA synthesis.

Vitamin B12 is one of the 13 essential vitamins required for human health. Unlike other vitamins, it is not produced by plants or synthesised through sunlight exposure. Instead, it’s made by bacteria and is found naturally in animal-based foods such as meat, fish, dairy, and eggs.

Despite its presence in food, B12 absorption can be challenging due to a complex process involving stomach acid, digestive enzymes, and specific transport proteins. After being released from food in the stomach, B12 binds to haptocorrin, is released again in the small intestine, and finally binds to Intrinsic Factor to be absorbed in the ileum. From there, it is transported via Transcobalamin II to body tissues. Any disruption in this pathway - due to low stomach acid, gut issues, or dietary restrictions - can impact B12 status.

Vitamin B12 deficiency can affect anyone at any age, but certain groups are at higher risk. These include vegans and vegetarians, adults over 60, individuals with eating disorders such as anorexia or bulimia, and those taking medications like antacids or diabetes treatments that interfere with B12 absorption. People with a history of alcoholism, anaemia, or gastrointestinal conditions such as Crohn’s disease and IBS are also more vulnerable. Autoimmune conditions like type 1 diabetes, Addison’s disease, and SLE can increase risk, as can a family history of pernicious anaemia. Women with infertility or recurrent miscarriage, as well as infants born to or breastfed by deficient mothers, should also be aware of their B12 status.

What Is Hydroxocobalamin?
Hydroxocobalamin is a stable form of vitamin B12 that contains a cobalt ion within a corrin ring structure, bonded to a hydroxyl group (-OH). It is well regarded for its longer retention time in the body. Once absorbed, it is converted into the active forms methylcobalamin and adenosylcobalamin.

Metabolics Vitamin B12 (Hydroxocobalamin) Liquid offers an effective, easy-to-absorb B12 source in a convenient one-drop format.
