Sources of Vitamin B1
Fortified and Enriched Grains
Animal Meats
Squash, Black Beans and Flax Seed
Critical to the metabolism of Proteins, Carbohydrates and Fat
Essential Part of the Antioxidant System
Vitamin B2 (Thiamine)
Component of flavin adenine dinucleotide (FAD), an essential part of the antioxidant system in the body
Vitamin B2 (Riboflavin)
Vitamin B2 Deficiency
Dry Skin, Sore Throat and Inflammation
“Rusting”
Oxidative Stress
“Reactive”
Inflammatory Stress
Sources of Vitamin B2
Beef, Fish, Pork, Milk, Mushroom, Peanuts, Avocados and Eggs
Vitamin B3 (Niacin) Functions
Metabolism of Carbohydrates, Proteins and Fats
Component of nicotinamide adenine dinucleotide (NAD)
Vitamin B3 (Niacin)
Nicotinamide adenine dinucleotide (NAD)
Molecule that carries Hydrogen Ions and is used to make ATP, provides energy for our body
Vitamin B3 Deficiency
Inflammation of the Skin, Headache, Diarrhea, Memory Loss and even death
Sources of Niacin
Beef, fish, pork, milk, mushrooms, peanuts, avocados, and eggs
Component of Co-enzyme A (CoA)
Vitamin B5 (Pantothenic Acid)
Function of co-enzyme A (CoA)
Molecular link b/w Glycolysis and the Kreb’s Cycle
Function of Vitamin B5
Production of Cholesterol, Fatty Acids and coenzyme 10 (Q10)
Vitamin B5 Deficiency
Rarely seen (Severe Malnutrition)
Class of Vitamins including Vitamin B6
Pyridoxal, pyridoxine, and pyridoxamine
Function of Vitamin B6
Breakdown of Glycogen into Glucose and the production of Glucose and Neurotransmitters
Sources of Vitamin B6
Vitamin B6 is found in fortified grains and in dairy along with eggs, organ meats (e.g., liver), potatoes, bananas, parsnips, and some nuts (e.g., pistachios).
Vitamin B7
Biotin
Cofactor in many carboxylase enzymes, which are responsible for transferring carbon dioxide molecules and the metabolism of carbohydrates, fatty acids, cholesterol, and amino acids
Vitamin B7 (Biotin)
Biotin Deficiency
Hair loss (Alopecia), Dermatitis and issues with nails
Carboxylase Enzymes
Responsible for adding a carboxyl group to molecules – these carboxylation reactions are involved in almost every step in energy production.
DNA synthesis, red blood cell production, and in maintaining proper neurological function
Vitamin B12
Vitamin B12 Deficiency
Pregnancy, Vegans and Vegetarians
Anemia and Neurologic Disorders
Sources of Vitamin B12
Fortified grains, shellfish, fish, beef, and dairy
Folic Acid (Folate)
Helps regulate single-carbon transfers, both accepting and donating single carbons to chemical reactions
Helps make Red and White Blood Cells and Dna Replication
Folic Acid Deficiency
Rare; Anemia; May be found in pregnancy
Sources of Folic Acid
Fortified grains, seafood, lean meats and poultry, eggs, legumes (beans and peas), nuts, seeds, and soy products.
Folic Acid Supplements
In Pregnancy, for anemia and may prevent Neural Tube Defects
May help with Depression
