Vitamin B Complex Quiz

Vitamin B Complex Summary

• Vitamin B complex includes folate, folic acid, B12, thiamin, riboflavin, niacin, B6, pantothenic acid, and choline
• Units of measurement include Dietary Folate Equivalent (DFE) and Niacin Equivalents (NE)
• Functions include coenzyme roles in metabolism, neurotransmitter synthesis, and hemoglobin synthesis
• Absorption occurs through active transport, passive diffusion, and protein binding
• Excretion happens through urine, bile, and feces
• Excess is excreted through urine and storage in muscle
• Primary deficiencies can lead to anemia and neural tube defects, while secondary deficiencies are associated with alcoholism and malabsorption
• Symptoms of deficiencies range from anemia to dermatitis and neurological issues
• Related diseases include peripheral neuropathy, Wernicke-Korsakoff Syndrome, and pellagra
• Food sources include dark leafy greens, meat, fish, poultry, dairy, and fortified cereals
• Loss from cooking and inhibitors affect the availability of B vitamins in food
• Unknown toxicity for most B vitamins, but excess B6 from supplements can cause adverse effects

Vitamin B Complex: Key Facts and Functions

• Vitamin B complex includes folate/folic acid, vitamin B12, thiamin, riboflavin, niacin, vitamin B6, pantothenic acid, and choline.
• Units for measurement include Dietary Folate Equivalent (DFE) for folate and Niacin Equivalents (NE) for niacin.
• Functions of B vitamins include coenzyme roles in metabolism, DNA/RNA synthesis, energy metabolism, and neurotransmitter production.
• B vitamins have different absorption and excretion mechanisms, including active transport, passive diffusion, and reabsorption.
• Excess B vitamins are excreted through urine, and deficiencies can lead to various symptoms and related diseases.
• Primary deficiencies of B vitamins can result in conditions such as megaloblastic anemia and peripheral neuropathy.
• Secondary deficiencies may be associated with factors like alcoholism, malabsorption, and drug interactions.
• Symptoms of B vitamin deficiencies include anemia, dermatitis, confusion, irritability, and gastrointestinal issues.
• Related diseases due to B vitamin deficiencies include neural tube defects, Wernicke-Korsakoff Syndrome, and pellagra.
• Food sources of B vitamins include a wide range of plant and animal-based foods, and some vitamins can be lost during food processing.
• Inhibitors of B vitamin absorption and loss during food processing can affect the availability of these vitamins in the diet.
• While there is no known toxicity from a diet rich in B vitamins, excessive intake of certain B vitamins through supplements may have adverse effects.
