Study Notes

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.
