PROVIDED BY NATURE Vitamin B12 is required for the development and function of a healthy immune and nervous system. Vitamin B12 is essential for the production of red blood cells and so maintaining correct levels of B12 can reduce tiredness and fatigue while also promoting better sleep. Vitamin B12 is more abundant in animal-based diets and so is particularly recommended for vegetarians and vegans. PERFECTED BY SCIENCE Methylcobalamin is a metabolically active form of vitamin B12. As Vitamin B12 is water-soluble and not fat soluble, it is regularly flushed out of the body and so needs to be taken daily. Vitamin B12 (with Vitamin B6) reduces levels of homocysteine. Regulating levels of homocysteine reduces the risk of cardiovascular disease and cognitive decline. PROVEN BY RESEARCH Vitamin B12 is “an essential molecule for humans.” Individuals following vegetarian diets are at risk of developing vitamin B12 deficiency owing to suboptimal intake. As vitamin B12 is essential for the synthesis of nucleic acids, erythrocytes and in the maintenance of myelin, deficiency may result in a variety of symptoms. Vegans who do not ingest vitamin B12 supplements were found to be at especially high risk. Vegetarians, especially vegans, should give strong consideration to the use of vitamin B12 supplements to ensure adequate vitamin B12 intake.
