Summary: Vitamins are essential organic compounds that are necessary for good health but cannot be synthesized by the human body. Vitamins B6 and B12 are hydrophilic vitamins that play vital roles in cellular operation, growth, and development. This review focuses on the important aspects of vitamins B6 and B12, including their roles, consequences of deficiency, food sources, and chromatographic techniques developed in the last two decades for their determination.

Summary: This review summarizes the complex metabolic pathway of Vitamin B12 deficiency, describes the causes of inherited and acquired Vitamin B12 deficiency, and highlights the differences in international practice regarding prescribing Vitamin B12 replacement therapy. Furthermore, the review discusses the evidence supporting novel modes of B12 replacement such as sublingual, intranasal, and subcutaneous routes, and compares them to intramuscular and oral routes in terms of patient compliance and cost-saving.

Summary: Vitamin B12 plays a crucial role in DNA synthesis for cell division, with deficiency particularly impacting rapidly dividing cells like glioblastoma cells. Antagonists of cobalamin have potential as anti-glioma agents, as shown by inducing cobalamin deficiency to inhibit glioblastoma cell growth and promote cell cycle arrest. This study suggests that cobalamin deprivation could be a promising therapeutic strategy for glioblastoma, with further exploration warranted.

Summary: This study evaluated the association between vitamins B6, B12, and folate concentrations/status and early childhood development (ECD) and found that vitamin B6 was positively associated with DQ, while vitamin B12 was negatively associated with DQ. There was no significant association between folate status and DQ.

Summary: Developing a resilient food supply is crucial in delivering necessary nutrients to consumers and addressing micronutrient deficiencies that can lead to severe health issues. Therefore, focus should be on enhancing minerals and nutrients in food through various methods to improve the sustainability of the food system.

Summary: The study found no significant association between vitamin B6, B12, and folate intakes and both global and subcortical brain volumes among participants with depression. However, vitamin B12 intake was positively associated with right pallidum among non-depressed participants, and a significant interaction between vitamin B12 intake and depression status on the right pallidum was observed. Additionally, a significant interaction between folate intake and depression status on grey matter volume and left thalamus was observed.

Summary: Vitamin B12 is essential and obtained exclusively from diet, with certain population groups at risk of subclinical deficiency. Poor intake of animal products and age-related decrease in intestinal B12 uptake contribute to the risk of deficiency in elderly population.

Summary: The analysis of natural cobalamins in dairy products is challenging due to the complexity of the matrix, low concentration level, light sensitivity, and binding to proteins. This study developed a sensitive and selective method using UHPLC-MS/MS to quantitate vitamin B12 in ripened cheeses from different species, revealing species-dependent differences in vitamin B12 concentrations.

Summary: This study aimed to investigate the status of B6, B12, and folate levels in pregnancy and their associations with low birth weight and preterm delivery. The results showed that a large proportion of pregnant women had low levels of B12, folate, and B6. Moreover, low B6 levels and impaired folate status were significantly associated with low birth weight.

Summary: Euglena gracilis, a freshwater protist, has various biotechnological applications and can be used for biofuel production, pharmaceuticals, and water remediation. However, its large-scale cultivation is limited by the high cost of adding vitamins B1 and B12 to the media. This study demonstrates that E. gracilis can be grown for long periods without the need for added vitamins B1 and B12 in a co-culture system involving the filamentous fungus Cladosporium westerdijkiae and the bacteria Lysinibacillus boronitolerans and Pseudobacillus badius. This finding significantly reduces the cultivation costs and the fungus C. westerdijkiae can be used for effective harvesting of E. gracilis through bioflocculation.

Summary: This study found that higher intake of dairy products, especially milk and yogurt, is positively associated with adequate levels of vitamin B-6, B-12, and folate, and lowers the risk of deficiency or inadequacy of these vitamins.

Summary: This systematic review aimed to assess the evidence for whether habitual or different levels of experimental intake of vitamin B12 from diet and supplements is sufficient to ensure adequate B12 status in groups most susceptible to vitamin B12 deficiency. The search yielded 18 included studies, and the conclusion was that the evidence is currently insufficient to determine if or which level of B12 intake is sufficient to maintain adequate status for all included populations.
