Biotin is a water-soluble vitamin that can be attached to a variety of proteins and nucleic acids, often without altering their properties. Its use in molecular biology is introduced here.

Vitamin B12 (also known as cobalamin) is an essential water-soluble vitamin that plays a pivotal role for several physiologic functions during one’s lifespan. Only certain microorganisms are able to synthetize B12, thus humans obtain cobalamin exclusively from their diet, specifically from animal-derived foods. Specific sub-group populations are at risk of vitamin B12 subclinical deficiency due to different factors including poor intake of animal source foods and age-dependent decrease in the capacity of intestinal B12 uptake. Consumption of animal products produces some negative health issues and negatively impacts sustainability while a plant-based diet increases the risk of B12 deficiency. Taking a cue from the aforementioned considerations, this narrative review aims to summarize facts about B12 deficiency and the burden of inadequate dietary intake in elderly population, as well as to discuss sustainable approaches to vitamin B12 deficiency in aging population.

I was happy to read the report from Greer et al.1 This biochemically confirms the clinical observation that the majority of children who develop clinical rickets are breast-fed. During the ten years, 1970-1979, I have seen six cases of clinical rickets. All of these infants were breast-fed.2 The only exception has been the rickets of prematurity. I should like to commend, again, the report from the Department of Pediatrics and Biochemistry of the University of Wisconsin.
