Study Notes
Vitamin A
- Plays a crucial role in maintaining healthy eyes, promoting bone and tooth growth, and regulating genes.
- Deficiency, uncommon in developed countries, can cause night blindness, bone problems, and infections due to a weakened immune system.
- Found in egg yolks, liver oil, meat, cheese, and butter.
Vitamin B1 (Thiamine)
- Essential for converting food into energy, maintaining healthy skin, and supporting a healthy nervous system.
- Deficiency, known as beriberi, can be dry or wet.
- Dry beriberi causes neuropathy due to nerve damage.
- Wet beriberi causes dilated cardiomyopathy, leading to enlarged and weakened heart chambers, potentially resulting in heart failure.
- Water-soluble, meaning excess amounts are eliminated through urine.
- Found in eggs, meat, yeast, vegetables, and nuts.
Vitamin B2 (Riboflavin)
- Assists in converting food to energy and maintains blood health.
- Water-soluble.
- Deficiency usually results from malnutrition or a lack of dairy and meat, particularly in those with lactose intolerance.
- Found in milk, whole grains, eggs, yeast, mushrooms, and leafy green vegetables.
Vitamin B3 (Niacin)
- Functions similarly to vitamins B1 and B2.
- Deficiency leads to pellagra, characterized by diarrhea, dermatitis, dementia, and potentially death.
Vitamin B5 (Pantothenic Acid)
- Aids in the production of lipids, neurotransmitters, steroid hormones (like testosterone and progesterone), and hemoglobin (a protein in red blood cells).
- Found in chicken, broccoli, avocados, and tomatoes.
Vitamin B6 (Pyridoxine)
- Regulates amino acids, impacting sleep, appetite, and mood.
- Helps create red blood cells.
- Found in fish, legumes, potatoes, and bananas.
Vitamin B7 (Biotin)
- Helps synthesize glucose, break down fatty acids, and maintain healthy bones and hair.
- Deficiency is rare but can occur due to consuming raw egg whites (avidin inhibits absorption).
- Widely found in various foods.
Vitamin B9 (Folate)
- Important for cell creation.
- Often taken by pregnant women to promote fetal brain health.
- Found in asparagus, okra, spinach, and orange juice.
Vitamin B12 (Cobalamin)
- Crucial for DNA synthesis and the metabolism of fatty acids and amino acids.
- Deficiency causes megaloblastic anemia, resulting in large, ineffective red blood cells.
- Symptoms include walking difficulties, numbness/tingling in hands/feet, and fatigue.
- Found in meat-based products.
Vitamin C (Ascorbic Acid)
- Found only in fruits and vegetables, especially citrus fruits.
- Acts as an antioxidant, neutralizing free radicals.
- Deficiency leads to scurvy, a disease marked by slow wound healing, easy bruising, tooth loss, gum disease, skin bleeding, and ultimately, death.
Vitamin D
- Regulates mood and aids in calcium and phosphorus absorption, crucial for strong bones and teeth.
- Deficiency causes osteomalacia (soft bones) in adults and rickets in children, leading to skeletal deformities.
- Infants were often given cod liver oil (vitamin D-rich) to prevent rickets.
- Produced through sunlight exposure.
Vitamin E (Tocopherol)
- Primarily found in fruits, seeds, and seed oils.
- Protects other nutrients, like vitamin A, and certain lipids from damage.
- Prevents Alzheimer's disease (note: the evidence for this is debated).
- Deficiency, although rare, can lead to impaired coordination, muscle weakness, and possibly paralysis.
- Vitamin E is crucial for red blood cell integrity, so deficiency can cause anemia.
Vitamin K
- Essential for blood clotting, activating proteins and calcium for this process.
- Produced by gut bacteria, also found in cabbage, liver, broccoli, and kale.
- Deficiency can result in excessive bleeding after injuries, osteoporosis, and increased cardiovascular risk.
