Summary
This narrative review, part of a larger systematic examination of B-complex vitamins, synthesises current knowledge on the biological properties of thiamine (B₁), riboflavin (B₂), niacin (B₃), and pantothenic acid (B₅). The authors characterise their roles as essential cofactors in energy metabolism, cellular signalling, and biosynthetic pathways, alongside discussion of bioavailability, absorption mechanisms, and clinical manifestations of deficiency. The work appears designed to provide an evidence-based reference for understanding how dietary adequacy of these micronutrients supports human physiological function.
UK applicability
The micronutrient content and bioavailability of B vitamins are relevant to UK dietary guidance and food fortification policy. Findings may inform discussions on dietary adequacy thresholds, particularly for vulnerable populations, and could support evidence-based recommendations on nutrient-dense food systems.
Key measures
Biochemical mechanisms, cofactor functions, absorption and metabolism, deficiency symptoms, recommended dietary allowances, therapeutic applications
Outcomes reported
The study reviewed the biological properties, mechanisms of action, and health effects of B vitamins (B₁, B₂, B₃, B₅). It synthesised evidence on the physiological roles, bioavailability, and clinical significance of these micronutrients.
