Vitamin B Complex: Key Facts and Functions

Vitamin B complex consists of eight water-soluble vitamins: folate, vitamin B12, thiamin, riboflavin, niacin, vitamin B6, pantothenic acid, and choline.
The units of measurement for these vitamins include Dietary Folate Equivalent (DFE) and Niacin Equivalents (NE).
Functions of vitamin B complex include coenzyme roles in nucleic acid metabolism, DNA/RNA synthesis, energy metabolism, and neurotransmitter production.
Absorption of these vitamins involves active transport, passive diffusion, and specific mechanisms in the small intestine.
Excretion of vitamin B complex vitamins primarily occurs through urine, with some reabsorption in bile and fecal losses.
Primary deficiencies of vitamin B complex vitamins can lead to conditions such as low plasma folate, megaloblastic anemia, and liver dysfunction.
Secondary deficiencies may arise due to factors like alcoholism, drug interactions, malabsorption syndromes, and certain diseases.
Symptoms of vitamin B complex deficiencies include anemia, weakness, fatigue, neuropathy, and skin conditions.
Related diseases associated with these vitamins include neural tube defects in pregnancy and Wernicke-Korsakoff Syndrome.
Food sources of vitamin B complex include a wide range of plant and animal-based foods, with some vitamins requiring fortification/enrichment.
Loss of vitamin B complex vitamins can occur during food processing, cooking, and exposure to inhibitors such as anti-thiamin factors and excess alcohol.
Bioavailability of these vitamins varies, with factors like food sources and cooking methods influencing absorption.
